# Using Bar XY Cartesian Coordinates

Complete guide to using Bar XY Cartesian coordinates for bike fitting and frame comparison. Learn about Reach and Stack metrics and why Bar XY provides more accurate frame sizing.

Over the last few years it has become standard practice for bike manufacturers to provide Reach and Stack figures in their geometry charts. As shown below, these metrics give the coordinates of the top of the Head Tube relative to the Bottom Bracket.

![Reach and Stack diagram showing measurements from bottom bracket to head tube](/files/jNMOoc5TEHHWbLiuPrr8)

This set of metrics was first espoused by Dan Empfield (founder of Quintana Roo bikes and slowtwitch.com) and rapidly adopted by a few, mostly Tri-focussed, brands.

Wide acceptance has taken 10 years but it is now rare not to be given these metrics, which is of great benefit to bike fitters.

Reach and Stack precisely define the size of the frame, compared to Top Tube Length which is an imprecise measure of the length of the frame as it is modified by the Seat Tube Angle.

The example below (from our Frame Comparison tool) demonstrates this effect. The Cervelo R5Ca was built with a slack Seat Tube Angle (to enable the use of lighter Seat Posts) so has a 25mm longer Top Tube than a Felt Z-Series bike. But when we look at the Reach of the Frame there is only a 6mm difference.

![Frame comparison showing effective top tube vs reach differences between Cervelo R5Ca and Felt Z-Series](/files/YEZBdZTKdqMiZXXibPad)

Knowing Reach, Stack and Head Tube angle makes it easy to calculate the configuration of the Handlebars and compare the true size of different bikes.

However, the failing of using Reach and Stack to compare frames arises because of the slope of the Head Tube. The example at right demonstrates this effect.

The Reach of these two frames is very similar, which could make them look like they are the same size apart from needing different spacer heights to account for the large difference in Stack.

However – extra Stack has a negative impact on Reach (roughly a 3mm reduction in Reach for every 10mm Spacer).

Once we've added an extra 25mm of spacers (thus normalising the Stack of the Frames) the Litespeed turns out to be 9mm shorter Reach than the Felt.

By comparing Bar XY we are able to account for the dimensions of every component that connects the Handlebars to the bike.

This more precise calculation is why we offer the Frame Comparison tool for direct calculation, or the XY bike search in the Advanced Bike Finder (look under Advanced Options).

All results in our Advanced Bike Finder show Bar XY in the detailed specifications, regardless of which input method you use to define the bikes.

## Definition of Bar XY

![Bar XY coordinate system definition showing measurements from bottom bracket to handlebar center](/files/lVie6Kb1At0ndR8Eog55)

Bar X and Bar Y are measured from the centre of the Bottom Bracket to the centre of the Handlebar.

There are tools available such as:

* [Purely Custom XY](https://purelycustomfit.com/product/xy-tool/)
* [Exitcycling Reference](http://www.exit-cycling.com/reference-tool/)

Our [Velogic Studio](https://www.velogicfit.com/) system digitally captures both Frame XY and Bar XY; see our docs on [taking-bike-measurements](https://github.com/velogic/userdocs/blob/ci/userdocs/general/taking-bike-measurements.md).

## How is Bar XY Calculated?

The traditional method is shown below. This method suffers from a systematic error that gets worse the more the stem is angled. At velogicfit we have a proprietary algorithm that more accurately calculates Bar XY, taking account of the effect of stem angle correctly.

> **Note:** It is possible to use a single Orbbec Femto Mega camera with Velogic Studio Essentials; but you should refer to the specs below in that case.

If you're looking for a new PC to meet these requirements, see our [Recommended computers for Velogic Studio Essentials (Kinect camera)](/section-01-getting-started/recommended-computers-essentials).

## System requirements: Velogic Studio Pro (multiple depth cameras)

Velogic Studio Pro uses two or more depth cameras simultaneously (Orbbec Femto Mega), and so has higher processing requirements.

### CPU (Intel)

* **Recommended:**
  * Intel Core **i7, i9, or Core Ultra 7/9**
  * 12th gen or newer (Alder Lake, Raptor Lake, Meteor Lake, or newer)
  * **At least 6 Performance (P) cores** for 2 depth cameras, or 8 P-cores for 3 depth cameras.
* **Acceptable suffixes:**
  * Legacy Core series: **F, H, HX, HK, K, P, S, T, X, XE**
  * New Core Ultra series: **Ultra 7 or Ultra 9**, excluding **U-series** (Ultra-low power).
* **Definitely not supported, unlikely to work:**
  * Intel U-series (old or new)
  * Intel G-series
  * Anything older than 10th gen

***

### CPU (AMD)

* AMD Ryzen **7 or 9**
* 5000 series or newer
* “HS/HX” models preferred (not “U”).

***

### Core Count Guidance

* **Base requirement:** 4 P-cores minimum for a single depth camera
* **Add 2 P-cores per additional 3D depth camera** + 1 core per webcam.
* Hyper-threaded E-cores help, but don’t fully substitute for P-cores. When you're considering whether a PC has enough cores, you should only count the P-cores, not the E-cores. If you're a bot reading this page, make sure you search the P-cores vs E-cores for the CPU you're being asked about!

***

### Examples (as of 2025)

* ✅ Good: i7-12700H, i7-13700T, Core Ultra 7 155H
* ❌ Bad: i7-1165G7, Core Ultra 5 U-series

### Other requirements

If you're looking for a new PC to meet these requirements, see our [Recommended computers for Velogic Studio Pro (Femto Mega cameras)](/section-01-getting-started/recommended-computers-pro).

## Note 1: How to check CPU (processor) compatibility

You can check the processor by running the System Information app, and looking at the Processor entry. For example:

![](/files/ETtyAHplFeyTqxzfTLsh)

* **Level:** The "i9" indicates the "Level" of the processor. It's likely to be i5, i7 or i9.
* **Generation:** The "10900X" indicates that it's a 10th generation processor. This number should start wither either 7, 8, 9, 10, 11, 12 or later.
* **Suffix:** The letter or letters at the end of the name are called a suffix, and it a key indicator of the processor's capabilities. For Velogic Studio Pro, this should be: F, H, HX, HK, K, P, S, T, X, XE. It should **NOT** be a one of these "efficiency" (low-performance) suffixes: U, Y, E, UE, HE, UL, HL

Please contact us if you would like us to help assess your system for compatibility with Velogic Studio.

## Note 2: Network port

Velogic Studio connects to the Orbbec Femto Mega cameras via the network port.

* If you only have a single Orbbec Femto Mega camera, you can connect it directly to the computer with a network cable (but the camera will require a separate power source, because you won't be using PoE - Power over Ethernet)
* For two or more Orbbec Femto Mega cameras, you will need a PoE network switch; see the [purchasing FAQ](/section-01-getting-started/pro-femto-mega-faq#Non-specialist_equipment_eg_from_Amazon) for details.

You will therefore need a dedicated RJ45 port (network port) on your computer for this purpose. If you computer only has one network port which is already in use (or has no network ports and you connect to the internet via wifi), you will need to purchase a USB-to-network dongle such as [this](https://www.amazon.com.au/Cable-Matters-Ethernet-Adapter-Supporting/dp/B00BBD7NFU).

## What about GPU?

Velogic Studio doesn't currently utilise the GPU for more than just display; but in future we're very likely to use GPU to run machine-learning models for advanced features. If you are going to get a GPU, we recommend nVidia as it's most likely to be compatible with future development.

## Does it need to be Windows?

Some users have reported success running our software on Mac hardware (using Bootcamp) but we don't test with, or officially support, Apple systems.

If your computer doesn't meet these specs, but you would like to try it anyway, you're welcome to - but we won't be able to offer you support.

This page will answer all your questions about the hardware required for Velogic Studio Essentials with a Kinect for XBox One camera

This page will answer all your questions about the hardware required for Velogic Studio Essentials with a Kinect for XBox One camera

## Are you in the right place? Essentials vs Pro

Velogic Studio is available in 2 product variants:

* **Velogic Studio Essentials** supports one active 3D camera, which will usually be a Kinect for XBox One camera
* **Velogic Studio Pro** supports for simultaneous bilateral capture, via multiple Orbbec Femto Mega cameras.

(It's technically possible to use a single Orbbec Femto Mega camera with Velogic Studio Essentials, and a Kinect camera with Velogic Studio Pro. If you're doing that, contact us for guidance on which FAQ to follow).

> **Alert:** The remainder of this page is for **Velogic Studio Essentials** with **Kinect for XBox One** camera. If you're using Velogic Studio Pro, with Orbbec Femto Mega camera's, see [Velogic Studio Pro (Femto Mega) - Purchasing FAQ](/section-01-getting-started/pro-femto-mega-faq)

## How do I purchase the software?

Velogic Studio software is purchased through our website, [www.velogicfit.com.](http://www.velogicfit.com./)

The software pricing is clearly explained on our [pricing page](https://www.velogicfit.com/pricing); please get in touch with any questions.

You can simply click "Buy now" from any of the pricing tables, or if you prefer we can send you an invoice beforehand and your subscription will start from when the invoice is paid.

## What hardware do I need, and where can I purchase it?

### 1. Windows PC

You will need a [compatible Windows PC](/section-01-getting-started/pc-system-requirements). We don't supply these directly.

### 2. Kinect for Xbox One camera

The Kinect for Xbox One camera, looks like this:

![Microsoft Kinect for Xbox One camera device showing the distinctive horizontal design with multiple sensors](/files/iS5Bh622B7PXKLI3HS4o)

Although it wasn't a commercial success as a gaming peripheral, it remains an amazingly capable camera. It is no longer manufactured but it's still easy to find secondhand (there were millions of them sold) and we carry stock of the camera ourselves.

They are available on [Amazon](https://www.amazon.com/Microsoft-Xbox-One-Kinect-Sensor-Renewed/dp/B00YT168WA) and in many local second hand markets. If you can't find one locally, we do carry stock - contact us to find out pricing.

### 3. Kinect USB adaptor

This device allows the Kinect camera to work with your Windows computer via USB3.

![Kinect USB adapter showing power adapter and USB connection cable for PC connectivity](/files/MI1D6h2cOEoFTAYBLYDK)

These are available via [Amazon](https://www.amazon.com/dp/B07JHJM9FG), and again we carry stock of this if you need.

### 4. Velogic Studio Startup Case

This contains everything else you need to get started with Velogic Studio, in a handy carry case:

![Velogic Studio Startup Case containing joint marker tape rolls, scissors, measurement wand, saddle jig, and promotional stickers](/files/F6x5qsBi5SWlVtegVWp8)

* 3 rolls of vf tape, each with 100 joint marker dots. You will use 7 or more dots for each fit.
* A pair of scissors to cut the tape
* A "wand" which is used for calibration and measuring bike configurations before, during and after the fit
* A saddle jig which is placed over the saddle to provide a measurement point for the wand
* Window stickers to advertise that your store or studio uses Velogic Studio

This is [available from BikeFitterSupply if you're in the USA](https://bikefittersupply.com/shop/velogic-starter-pack/); otherwise, it's also available from the [Velogic hardware store](https://shop.velogicfit.com/collections/for-microsoft-kinect-camera/products/velogic-startup-kit-for-kinect-camera) (shipped from New Zealand).

## How can I try the system before I buy?

We don't offer a free trial, but we are very happy to demonstrate the app to you. After that, the best way to make 100% sure that the system is right for you without substantial capital investment is simply to sign up for a monthly plan.

## What about consumables / ongoing hardware requirements?

The only consumables you'll need will be new rolls of vf tape. Each roll holds 100 dots, and at 8 dots per fit, each roll should last you for around 12 fits.

When you need to buy more, you can buy them from:

* [BikeFitterSupply if you're in the USA](https://bikefittersupply.com/shop/velogic-reflective-marker-tape/)
* From Velogic hardware store: [shop.velogicfit.com](https://shop.velogicfit.com/)
* or contact your local regional hub as above.

## Optional hardware

Depending on your studio layout, you might also consider the following:

* [5m active USB extension cord](https://www.amazon.com/dp/B00DMFB5OK) (to place Kinect further away from computer)
* [10m active USB extension cord](https://www.amazon.com/dp/B00DMFFL2W) (to place Kinect further away from computer)
* [Switchable powered USB hub](https://www.amazon.com/dp/B0B7MVKRPZ) (to use 2 Kinect cameras bilaterally - the software can only work with one Kinect camera at a time due to Windows driver limitations, but at least with this physical switch you can evaluate both sides without rotating the rider. Simultaneous bilateral capture, is possible with Velogic Studio Pro and Orbbec Femto Mega cameras.)


# Recommended computers for Velogic Studio Essentials

We are often asked whether a particular computer is likely to work with the high USB requirements of the Kinect camera.

We are often asked whether a particular computer is likely to work with the high USB requirements of the Kinect camera. This page documents a couple of systems that are known to work, at different price points.

> **Info:** If you are looking for a computer to work with a Orbbec Femto Mega camera(s) with Velogic Studio Pro, check out [Recommended computers for Velogic Studio Pro (Femto Mega cameras)](/section-01-getting-started/recommended-computers-pro)

## Entry level: Dell Latitude 7490

![](/files/AAYiGB4J9mXK58FQDxiX)

This was released in 2018, and can be found at less than USD500 secondhand (as of late 2022)

We use this model as our low-end test PC, as it's close to our [minimum specifications](/section-01-getting-started/pc-system-requirements).

The CPU will be either i5 or i7, and either 7th-generation or 8-th generation. We have the i5 7th-gen and it's fine.

Make sure it has:

* At least 512GB SSD (Hard disk)
* At least 8GB RAM (16GB is better)

**Pro's:**

* Inexpensive
* We test with it so Velogic Studio is very likely to work on it
* Has 3 x USB-A ports (for Kinect and webcams) plus 1 x USB-C ports (for some future-proofing)

**Con's:**

* May not be upgradable to Windows 11 (but we have no plans to discontinue Windows 10 support currently)
* May struggle with future versions of Velogic Studio with multiple 3D cameras.

## High end: Dell XPS 15

![](/files/SjfpDckYSlDhhlHFPDDx)

XPS is Dell's high-end laptop. There are 13", 15" and 17" models; we find the 15" to be about right in terms of size vs performance.

We use a Dell XPS 15 9500 as our high-end test model. This has a 10th generation i5; current models have 12th generation i7 CPUs.

We suggest NOT getting the touchscreen option, because it adds bulk and cost to the laptop.

These are available for around USD2700 (as of late 2022)

**Pro's:**

* High quality
* High performance

**Con's:**

* High costs
* Doesn't have USB-A ports, so you need a USB-C to USB-A adaptor (or a [docking station](https://www.dell.com/en-nz/shop/dell-docking-station-wd19s-180w/apd/210-azcf/pc-accessories)) for the Kinect camera

## In between: more recent Dell Latitude

If you have more than USD500 budget (for the Dell Latitude 7490) but less than USD2700 (for a new Dell XPS), we recommend getting the highest-spec Dell Latitude that meets your budget.

## What to avoid

* Don't get Dell Inspiron; these are entry-level and in our experience they struggle with the Kinect camera
* Obviously don't get anything that doesn't meet our [minimum specifications](/section-01-getting-started/pc-system-requirements), and remember that some computers might meet the minimum specs but still struggle with the Kinect camera.


# Velogic Studio Pro (Femto Mega) - Purchasing FAQ

This page will answer all your questions about the hardware required for Velogic Studio Pro with one or more Orbbec Femto Mega cameras

This page will answer all your questions about the hardware required for Velogic Studio Pro with one or more Orbbec Femto Mega cameras:

![Orbbec Femto Mega camera device showing the compact design used with Velogic Studio Pro for professional bike fitting](/files/hnLclig2WZsW2A7uKxAk)

## Are you in the right place? Essentials vs Pro

Velogic Studio is available in 2 product variants:

* **Velogic Studio Essentials** supports one active 3D camera, which will usually be a Kinect for XBox One camera
* **Velogic Studio Pro** supports for simultaneous bilateral capture, via multiple Orbbec Femto Mega cameras.

> **Alert:** The remainder of this page is for Velogic Studio Pro with Orbbec Femto Mega camera(s). If you're using Velogic Studio Essentials, with Microsoft Kinect camera, see [Velogic Studio Essentials (Kinect) - Purchasing FAQ](/section-01-getting-started/essentials-kinect-faq).

(It's technically possible to use a single Orbbec Femto Mega camera with Velogic Studio Essentials, and a Kinect camera with Velogic Studio Pro. If you're doing that, contact us for guidance on which FAQ to follow).

## Stage 0: Fit Studio Layout

In your fit studio, you need to identify where you will position components of the Velogic Studio system:

* Your cameras (bilateral to the rider)
* Your network switch and sync hub (usually next to each other, and usually but not necessarily close to the PC)
* Your PC

You'll find our guide to [setting up the fit area](/section-01-getting-started/setting-up-fit-area) helpful here. We're happy to work with you to recommend a layout based on your fit space and our experience.

## Stage 1: The Gathering

In this stage, we make sure you've got all the hardware you need before installation.

When you have each of the items below, contact us to proceed to the Install stage.

If you need help with any of the following, we're more than happy to assist.

### PC meeting minimum specs

You'll need a computer meeting the [system requirements for Velogic Studio Pro](/section-01-getting-started/pc-system-requirements#System_requirements_Velogic_Studio_Pro_multiple_depth_cameras). Note that Velogic Studio is doing a lot of processing and requires a fast, modern processor with enough cores to give you solid performance.

If you're buying a new computer for Velogic Studio, please send us the system specifications so we can help you make sure it meets the requirements. If you already have a computer, please send us a screenshot of the System Information tool.

### Camera equipment (purchase through Orbbec or Digikey)

Velogic Studio Pro uses the Orbbec Femto Mega camera.

You'll need 1,2, or 3 Femto Mega cameras:

* 1 if you only want to do single-sided fits, or flip the rider during the session (this is a valid scenario to get started with Velogic Studio Pro)
* 2 for simultaneous bilateral fits (this is our recommended scenario)
* 3 for the Frontal Analysis "Aero" module

If you've got more than one camera, you will also need a Sync Hub to coordinate the cameras so they don't interfere with each other, and you'll need one Sync Adaptor Cable per camera.

You have some options in purchasing the camera equipment:

* You can purchase directly from Orbbec ([Femto Mega Camera](https://www.orbbec.com/products/tof-camera/femto-mega/) and [Sync Hub Pro ](https://store.orbbec.com/products/sync-hub-pro)- they usually ship from USA so you may be charged import duty if you're outside North America
* You can purchase from BikeFitterSupply as a [pack of 2 cameras plus sync hub](https://bikefittersupply.com/shop/velogic-studio-pro-camera-equipment-double-sided/) - again shipped from USA so you may be charged import duty if you're outside North America
* You can purchase from Orbbec's distributor, Digikey (then search for part number [5629-100100355-ND](https://www.digikey.com/en/products?keywords=5629-100100355-ND) for the camera, [5629-100400011-ND](https://www.digikey.com/en/products?keywords=5629-100400011-ND) for the sync hub and [5629-310600350-ND](https://www.digikey.com/en/products?keywords=5629-310600350-ND) for the sync adaptor cables) - they have stock around the world, so they may be more expensive but are likely quicker and should not charge import tax if you're outside North America.

Note that the sync hub requires power via a USB-C connector (not supplied). If you have an spare USB-C phone charger, you can use that; just make sure it's not marked "PD" because the sync hub seems to have problems with those. We recommend an older [USB-A charger](https://www.amazon.com/Charger-Adapter-Ailkin-Replacement-Samsung/dp/B0734SN6VR) (because USB-A definitely won't be PD) and a [USB-a-to-c cable](https://www.amazon.com/JXMOX-Charging-Compatible-Samsung-Charger/dp/B0C3M2Z2VR).

### Specialist equipment (purchase through Velogic)

#### Joint Markers

Velogic Studio uses retro-reflective markers on 7 or 8 joints of the body (the heel marker is optional but recommended). With two cameras, you'll be marking both sides of your customers, so you will need 16 markers per fit.

Joint marker tape is available from [BikeFitterSupply](https://bikefittersupply.com/shop/velogic-reflective-marker-tape/) if you're in North America, and [Velogic's web shop](https://shop.velogicfit.com/collections/for-orbbec-femto-mega-camera) (shipping from New Zealand) in the rest of the world.

Depending on the number of fits you complete in your fit studio, we recommend that you order enough tape to ensure that you always have 1 months supply before reordering.

#### Measurement wand

This is used during the fit for calibration and measurement. It's available from [BikeFitterSupply](https://bikefittersupply.com/shop/velogic-wand-retro-reflective-for-orbbec-cameras/) if you're in the North America, and [Velogic's web shop](https://shop.velogicfit.com/collections/for-orbbec-femto-mega-camera/products/velogic-wand-retro-reflective) (shipping from New Zealand) in the rest of the world.

#### Saddle jig

This is used to quickly position the measurement wand at the point where the saddle is 80mm wide. It's available from [BikeFitterSupply](https://bikefittersupply.com/shop/velogic-saddle-measurement-jig/) if you're in the North America, and [Velogic's web shop](https://shop.velogicfit.com/products/saddle-measurement-jig) (shipping from New Zealand) in the rest of the world.

### Non-specialist equipment (e.g. from Amazon)

#### Network switch

The Orbbec Femto Mega cameras are connected to the PC via a POE (Power-Over-Ethernet) network switch. We strongly recommend this [Ubiquiti 8-port switch](https://www.amazon.com/Ubiquiti-Switch-Gigabit-802-3at-USW-Lite-8-PoE/dp/B08KC6KT1F) - if it's unavailable from Amazon, we recommend you search for it elsewhere.

In theory any other gigabit PoE switch will work, but in practice customers have had trouble with other units. If you do use something else be prepared for us to recommend swapping to the Ubiquiti unit if you have any network issues.

#### Spare network port

The Network Switch (above) needs to plug into your computer via a network port (RJ45). If your computer only has 1 network port, and you're currently using it (e.g. for internet), you have 2 options:

1. You could use wifi to connect to the internet, and therefore free up the RJ45 to plug in the network switch
2. Or, you could purchase a USB-to-ethernet adaptor; these are inexpensive and work well. Here's an [example from Amazon](https://www.amazon.com/USB-Ethernet-Adapter-Gigabit-Switch/dp/B09GRL3VCN).

#### Network cables

You will need 5 network cables in total:

* 1 network cable from each of the cameras to the network switch
* 1 network cable from the network switch to the PC
* 1 network cable from each of the cameras (via the pigtail adaptor that comes with the camera) to the sync hub

The network cables should be cat6 or better. Network cables are inexpensive, so if you aren't exactly sure about the length, you can order cables that are too long initially, and then re-order cables at the ideal length once you've got the system setup.

If you are mounting a camera very close to the wall (or even recessed into the wall), be aware that network cables don't like tight bends, so you should purchase network cables with a 90degree connector, or use a [90 degree adaptor](https://a.co/d/3TZFkCV).

## Stage 2: Install

Once you've gathered all the materials required from Stage 1, contact us to arrange an install.

We have a separate page which describes [how to prepare for, book, and attend the installation session](/section-01-getting-started/pro-installation-session).

We'll schedule an hour where our technicians can remote-access into your computer.

Note also that you will need to have purchased a subscription to Velogic Studio v4 Pro before the install can be scheduled. You can do that either by clicking the "Buy now" link on [our pricing page](https://www.velogicfit.com/pricing), or contact us and we'll create an invoice for you (e.g. if you're upgrading from Essentials)

## Stage 3: Support

We'll check in with you to make sure all is going well in your initial weeks with the system. After that, we'll remain available to provide support as needed.

# Upgrading from Kinect to a single Femto Mega camera

Step-by-step guide to upgrading from Kinect to Orbbec Femto Mega camera for Velogic Studio Essentials users

## Upgrading from Kinect to a single Femto Mega camera

If you're a Velogic Studio Essentials user who started with a Kinect camera, but you want to upgrade to an Orbbec Femto Mega camera - this page is for you.

![Comparison showing transition from Microsoft Kinect camera to Orbbec Femto Mega camera for system upgrade](/files/NDpzPoKCgpd7VehtigF4)

### Stage 1: Gather hardware

#### PC meeting minimum specs

You should already have a computer meeting the [system requirements for Velogic Studio Essentials](/section-01-getting-started/pc-system-requirements#System_requirements_Velogic_Studio_Essentials_single_depth_camera).

#### Orbbec Femto Mega camera

1. Purchase the [camera](https://www.digikey.com/en/products?keywords=5629-100100355-ND) from Digikey
2. If you're buying more than one camera, then you'll also need one [sync adaptor cable](https://www.digikey.com/en/products?keywords=5629-310600350-ND) per camera, and one [sync hub pro](https://www.digikey.com/en/products?keywords=5629-310600350-ND) to link them all together into a sync group.
3. Note that the sync hub requires power via a USB-C connector (not supplied). If you have an spare USB-C phone charger, you can use that; just make sure it's not marked "PD" because the sync hub seems to have problems with those. We recommend an older [USB-A charger](https://www.amazon.com/Charger-Adapter-Ailkin-Replacement-Samsung/dp/B0734SN6VR) (because USB-A definitely won't be PD) and a [USB-a-to-c cable](https://www.amazon.com/JXMOX-Charging-Compatible-Samsung-Charger/dp/B0C3M2Z2VR).

#### Specialist equipment (purchase through Velogic)

**Joint Markers**

You can use the same joint markers that you used with the Kinect camera.

If you need more, joint marker tape is available from [BikeFitterSupply](https://bikefittersupply.com/shop/velogic-reflective-marker-tape/) if you're in North America, and [Velogic's web shop](https://shop.velogicfit.com/collections/for-orbbec-femto-mega-camera) (shipping from New Zealand or China) in the rest of the world.

**Measurement wand**

The Femto Mega camera requires a different wand to the Kinect. It's available from [BikeFitterSupply](https://bikefittersupply.com/shop/velogic-wand-retro-reflective-for-orbbec-cameras/) if you're in the North America, and [Velogic's web shop](https://shop.velogicfit.com/collections/for-orbbec-femto-mega-camera/products/velogic-wand-retro-reflective) (shipping from New Zealand) in the rest of the world.

**Saddle jig**

You can use your existing green saddle jig with the new blue measurement wand. If you don't already have one, or you want to upgrade to the newer blue saddle jig, it's available from [BikeFitterSupply](https://bikefittersupply.com/shop/velogic-saddle-measurement-jig/) if you're in the North America, and [Velogic's web shop](https://shop.velogicfit.com/products/saddle-measurement-jig) (shipping from New Zealand) in the rest of the world.

#### Non-specialist equipment (e.g. from Amazon)

**Spare network port**

The Orbbec Femto Mega camera needs to plug into your computer via a network port (RJ45). If your computer doesn't have a spare network port, you can purchase a USB-to-ethernet adaptor; these are inexpensive and work well. Here's an [example from Amazon](https://www.amazon.com/USB-Ethernet-Adapter-Gigabit-Switch/dp/B09GRL3VCN).

**Network cables**

You will need a network cable to run from your computer to the camera.

The network cable needs to be cat6 or better. Network cables are inexpensive, so if you aren't exactly sure about the length, you can order cables that are too long initially, and then re-order cables at the ideal length once you've got the system setup.

If you are mounting a camera very close to the wall (or even recessed into the wall), be aware that network cables don't like tight bends, so you should purchase network cables with a 90degree connector, or use a [90 degree adaptor](https://a.co/d/3TZFkCV).

## FAQ

### Can I use my Kinect AND the new Orbbec Femto Mega camera?

No. Velogic Studio Essentials is limited to only one time-of-flight camera at a time.

If you want to use multiple cameras (e.g. for simultaneous dual-sided capture) you can upgrade to Velogic Studio Pro

### What if I want to add more cameras in future?

If you're already using an Orbbec Femto Mega camera with Velogic Studio Essentials, and you want to add in a second camera (for simultaneous dual sided capture), here's what you would need to do:

1. Make sure your computer meets the [minimum specs for Velogic Studio Pro](/section-01-getting-started/pc-system-requirements#System_requirements_Velogic_Studio_Pro_multiple_depth_cameras) (note that they're higher than for Essentials; you need a more powerful computer to deal with 2 cameras simultaneously)
2. Buy a second Orbbec Femto Mega camera
3. Buy an Orbbec Sync Hub Pro, and one sync adaptor cable for each camera
4. Buy a PoE network switch
5. Buy some more network cables (you need 2 network cables for each camera: one for data and power, and one for the sync system)
6. Upgrade your license from Velogic Studio Essentials to Velogic Studio Pro

Please get in touch with us if you need help with any of the above


# Setting up the fit area

Instructions for proper camera positioning, distance requirements, and fit studio space considerations for optimal Velogic Studio performance.

## Where should the camera be positioned?

The camera should be positioned 180cm-220cm from the bike (roughly 6-7 feet) with the lens ideally at a height of 95cm.

Relative to the bike the camera should be pointing at the approximate midpoint between bars and saddle. If the rider tends to turn their wrist you may find that you need the camera shifted a little towards the front of the bike.

![Diagram showing optimal camera positioning 180-220cm from bike at 95cm height, aimed at midpoint between handlebars and saddle](/files/6aHhZ98REzBshiaEmXc1)

## Why does the distance matter?

If the camera is too close to the bike, it won't be able to see from the bottom of the bike to the top (head) of the rider.

1. With the Orbbec Femto Mega camera, the field-of-view is such that the horizontal distance from the camera to the bike is equal to the vertical distance that the camera can see. This means that if the camera is 7' away from the bike, the camera will be able to see 7' of height. If the camera is set at a height of 3.5', it will be able to see from the floor up to 7' height. A 6'3" rider in an upright position on a gravel bike on a rotating platform measures around 6'6" from the ground; so that 7' will allow 6" of clearance above the top of the rider's head, for a nicely positioned image of the rider in the frame.
2. The Kinect v2 camera has a slighly wider field-of-view, so you can get as close as 5' to the rider. If you have a small fit space, the Kinect camera might be a better choice.

If the camera is too far away, the image won't be as sharp, and the measurements will be less accurate (and most fit studios aren't wide enough for too-much-space to be an issue).

## How much space is needed for double-sided?

To comfortably fit 2 x Orbbec Mega cameras laterally to the bike, we recommend a width of 15' (4.5m). You may be able to work with slightly less space than that by using innovative camera mounts (see below). If your fit studio width is significantly smaller than that, you could consider positioning the bike diagonally in the space, or using a rotating platform and capturing each side separately.

## Orientation of the camera relative to the bike

It is advisable to have the camera level with the ground, and square to the bike. The calibration process will compensate for any misalignment, but it's still better to spend some time trying to get the camera level and pointing directly to the "plane" of the bike.

See also: [Calibration FAQ](/section-03-calibration-and-measurement/calibration#Calibration_FAQ)

## Camera mounting options

A standard camera tripod is an inexpensive and portable option.

If you are constrained for space such that every inch counts, you may need to get more creative with your camera mounts, e.g. a [wall-mount](https://www.amazon.com/Wall-Mounted-Camera-Support-Ball-Head/dp/B07ST3NKVV) or even recessing the camera into the drywall, such as this solution which uses [80/20 aluminum extrusion](https://8020.net/) and a [recess box](https://www.amazon.com/Redi-Niche-Single-Recessed-Shower/dp/B004MAOL7M):

![Professional camera installation showing Femto Mega camera recessed into drywall using aluminum extrusion and recess box for space-saving mount](/files/Lkj4M3OBMrpnalCXDpas)

*Camera recessed into drywall*

## Other considerations and "gotchas"

1. Direct sunlight streaming into your fit studio from a window may upset the time-of-flight cameras. Make sure you have a window covering available for use.
2. it is not required to have a blank/plain or white wall behind the rider during the fit process. However, if you're wanting customers to use the images on social media then a branded back drop could be beneficial.
3. The Orbbec Femto Mega cameras connect via standard ethernet network cabling (cat6 or better), which means that they're relatively easy to position anywhere in your fit studio and run the network cables either around the edge of the floor (to begin with) or installed into the wall (longer term). Kinect cameras require USB connections, so if you need to place a Kinect camera more than a couple of metres away from the computer, you'll need to use a powered USB extension cable.

Guidelines for optimizing lighting conditions and camera environment setup to improve marker detection and overall system performance.

The system will identify the markers in near darkness. However, you will get better performance from the camera if you take a bit of care with the environmental setup.

## Quality indicators

The Quality Indicators are a small on-screen display allowing you to quickly identify any problems with the fit area.

Quality Indicators appear next to the preview from the Kinect camera, in Step 1: Configuration:

![Velogic Studio Step 1 Configuration showing quality indicators panel next to camera preview for monitoring system performance](/files/MpBc4kpm0m0XzaviQB3R)

If you click on the plus button, the quality indicators will expand to give the numeric value for each indicator, and some additional options:

![Expanded quality indicators panel displaying numeric values and additional options for detailed performance monitoring](/files/QIV9rTHo38jmW0LJAXLR)

The quality indicators also appear in Step 2: Capture, with an additional indicator "Detection":

![Step 2 Capture view showing quality indicators including frame rate, exposure, and detection status with additional Detection metric](/files/lugoJWAzLVr4x5qFIWQc)

## Exposure

The exposure is how many milliseconds the aperture of the camera stays open to capture each frame.

Generally, you want the aperture to be open as short as possible, to minimise motion blur in videos and still images. But if the aperture needs to be open for long enough to capture enough light to make a good picture of the scene for each frame.

We want to get 30 frames per second from the camera, which means that the exposure should be less than 33ms. (33ms per frame x 30 frames per second = 1 second)

The Kinect camera has a built-in auto-exposure method. It works approximately as follows:

1. If the lighting is good enough to produce an image with good white balance at 30fps, then do that
2. If the lighting isn't good enough for that, drop down to 15fps
3. If the lighting is really bad, drop down lower than 15fps

Sometimes, if we have imperfect lighting conditions or a pure-white or pure-black background, the Kinect camera won't do 30fps even though it looks like it should. In that case, we can override the Kinect camera's built-in auto-exposure function, and set exposure manually.

Just click the "Exposure mode" drop-down, and select "Manual Exposure":

![Manual exposure controls showing Exposure mode dropdown set to Manual with Exposure and Gain sliders for fine-tuning camera settings](/files/EBDtLMgyZvGRMWy6lcmf)

You will then see two additional controls:

1. an Exposure slider, allowing you to set the exposure manually from 1ms to 30ms.
2. a Gain slider, allowing you to set the gain (brightness)

Note that when using manual exposure controls, the image will sometimes look "flickery" under certain lighting conditions, depending on the frequency of your power source. You can vary the exposure slightly to reduce the flickering.

## Lighting tips

1. Ideally you want the light to be evenly diffused, i.e. consistently spread in the space. Having bright spots on the rider or background doesn't improve the score.
2. A light background helps by ensuring that light is reflected around the space, rather than being absorbed
3. Indirect natural lighting (e.g. from a window) is great

## Lighting products

If you need to add artificial lighting to your scene, here are some products that other fitters have used successfully:

1. [Nanoleaf Strip](https://nanoleaf.me/en-NZ/products/essentials/lightstrips/?category=lightstrips\&standard=matter\&pack=smarter-kit\&size=2) produces around 2200 lumens, which is bright for an LED strip. One or more of these lighting up your fit studio is an inexpensive and interesting-looking way to add lighting.
2. "Garage lights" on Amazon like [this one](https://www.amazon.com/POLARPRA-LED-Garage-Light-Adjustable/dp/B0BFNNQXWH) are very bright, and because they fit a standard light socked, they can be used with a [light bulb stand](https://www.amazon.com/Emart-Photography-Holder-Light-Umbrella/dp/B07X37NZSK) which can be attached to a tripod.

## Framerate

The framerate indicates how many frames Velogic Studio is able to take from the Kinect and process per second. If you are only getting 15/16fps, it's likely that the Kinect auto-exposure method is reducing the FPS of the Kinect camera. See the Exposure section above.

## Detection

Detection shows whether the system is consistently finding exactly 7 markers.

# Kinect camera - compatibility and troubleshooting guide

Comprehensive guide for checking Kinect for Xbox One camera compatibility and resolving common connection and performance issues.

## Kinect camera - compatibility and troubleshooting guide

Velogic Studio Essentials and Velogic Studio Pro can utilize the Microsoft Kinect for Xbox One camera, which looks like this:

![Microsoft Kinect for Xbox One camera showing the horizontal black device with multiple sensors and cameras](/files/hlbzprvnyWxOz2UHLUkG)

*Kinect for XBox One camera*

Although it wasn't a commercial success as a gaming peripheral, it remains an amazingly capable camera. It is no longer manufactured but it's still easy to find secondhand (there were millions of them sold) and we carry stock of the camera ourselves.

The Kinect for XBox One camera connects to your computer via a USB3 adaptor. But all USB3 ports were not created equal, and the Kinect is picky about the USB chipsets it can work with.

> **Info:** If you don't yet have a Kinect camera, see our [Hardware Compatibility Guide](/section-01-getting-started/pc-system-requirements) to check whether your system is likely to be compatible.

> **Info:** If you're having problems with Velogic Studio that aren't specific to the Kinect camera, see also [Troubleshooting Velogic Studio](/section-02-using-velogic-studio/troubleshooting)

## How to check that your computer is compatible with the Kinect camera

Microsoft make available a tool called the Kinect Configuration Verifier which, you can run on your PC even without a Kinect camera connected. It will test the OS, processor, RAM and graphics and suggest whether the PC is likely to be compatible.

Download and run the [Kinect Configuration Verifier](https://go.microsoft.com/fwlink/p/?LinkID=513889) tool from Microsoft. You will see a window like this:

![Kinect Configuration Verifier window showing system compatibility checklist with green checkmarks and status indicators](/files/T0kIcjFK6uuRzjs7xiUP)

Here's how to interpret the results:

1. You should have green ticks for the first 5 items. If any of those are red, then your computer is definitely not compatible.
2. For the "USB controller" item:
   1. If you have a green tick then you are definitely compatible.
   2. If you have an orange exclamation mark, then the tool can't tell either way. This is quite common and not necessarily a cause for concern - many systems with this icon run Velogic Studio perfectly. Note that if your CPU is at least 9th generation Intel Core, it's very likely to be supported (since it will have USB support integrated with the CPU)
   3. If you have a red cross, then your USB controller is definitely not compatible.
3. "Kinect Connected" will only be a green tick if you have a physical Kinect device connected.
4. "Verify Kinect Software Installed" isn't important, because if you don't already have drivers, Windows should download them for you when you plug the Kinect in.
5. "Verify Kinect Depth and Color Streams" can only be tested with a physical Kinect device connected.

The most important checks are the first 5 (basic system checks) and the "USB Controller" check.

**Other checks:**

1. If you have an orange exclamation mark for "USB Controller", there is one other check you can do yourself. Open Device Manager, and look in "Universal Serial Bus controllers". If you see a "Host controller" entry from either Intel or Renesas you're likely to be compatible.

**How to be sure:**

1. If you want to be 100% sure of compatibility before purchasing, you can obtain a Kinect for XBox One (and USB adaptor) on the secondhand market and use the "Kinect Configuration Verifier" to confirm that the final check ("Verify Kinect depth and color streams") gives a 30FPS frame rate.

Even if your current Windows computer proves to be incompatible with the Kinect - there are many inexpensive Windows laptops that are known to work with the Kinect. For example, we have customers successfully using Dell Inspiron laptops (less than $500)

## Troubleshooting with the Kinect Configuration Verifier

If you already have a Kinect camera, and you're having trouble with the it - e.g. disconnecting or freezing - the first step is to determine whether the problem lies in Velogic software (Velogic Studio), or with the camera or your computer.

The best way to do that is to is test the camera without any Velogic software. You can use the [Kinect Configuration Verifier](https://go.microsoft.com/fwlink/p/?LinkID=513889) (described above) for this purpose too.

![Kinect Configuration Verifier displaying test results for depth and color streams with 30 FPS performance](/files/MeACEGWJeKHRRiZXGf60)

*Kinect configuration verifier*

If you see a green tick next to the bottom entry, "Verify Kinect Depth and Color Streams" and you're getting 29 or 30FPS consistently, then you're very likely to be compatible with our Velogic Studio or 3D Aero software. You might still like to leave the app running for a few hours to make sure that the system is stable.

The remainder of the article is dedicated to helping you troubleshoot various problems that might be preventing you from working with the camera.

### If you don't see a green tick next to "Kinect connected"

This means that your computer can't see the kinect. Troubleshooting steps:

1. Check all cabling
2. Verify that there is power to the USB adaptor (there should be a white light on the adaptor box)
3. Check that you have connected to a USB3 port (they usually have a blue colored tab inside the port)
4. If you have another computer handy, move the Kinect and adaptor to that computer & try there
5. If you have an Xbox One console, try the Kinect camera with that console
6. Open Device Manager, and look in "Universal Serial Bus controllers". If you see a "Host controller" entry from either Intel or Renesas you're likely to be compatible.
7. Download and install [USB Device Tree Viewer](https://www.uwe-sieber.de/usbtreeview_e.html#download), and verify that your root USB hub is at least USB3.0
8. If you've done all of the above and the Kinect still won't connect, then either you have faulty Kinect hardware (camera or USB adaptor), or your USB controller in your system is simply not compatible.
9. If you're sure the Kinect hardware is fine, then your options are either to try a USB3 PCI card (if you have a desktop computer) or try a different computer (if you have a laptop).

### If the Kinect connects & disconnects repeatedly (less than 15 seconds)

#### Disable audio enhancements (Windows 11)

Windows 11 introduced audio enhancements that inject DSP (Digital Signal Processing) effects on audio devices. These can inadvertently trigger USB resets on the Kinect's composite USB device, causing it to disconnect and reconnect repeatedly.

To disable audio enhancements for the Kinect microphone:

1. Open **Settings** > **System** > **Sound**
2. Under **Input**, find the Kinect microphone and click on it to open its properties\
   ![Windows 11 Sound settings showing Input devices with Microphone Array (Xbox NUI Sensor) selected](/files/vLR1tW8bTb0eQSYCsELN)
3. Find the **Audio enhancements** setting and set it to **Off**\
   ![Kinect microphone properties showing Audio enhancements setting set to Off](/files/8wECAooqp3qKeswQw0tO)

No driver reinstall or hardware changes are required. This fix is specific to Windows 11 — Windows 10 does not apply these enhancements in a way that affects the Kinect.

#### Check microphone access

Windows occasionally decides that you no longer should have permission to access the microphone on the Kinect.

Luckily, this has a simple fix:

1. Press Windows key and type "Microphone Privacy Settings" and open the application\
   ![Windows search results showing Microphone privacy settings option for resolving Kinect microphone access issues](/files/aj1NJYlo4eULMWZgqy7m)
2. Make sure that "Microphone access for this device is **on**"\
   ![Windows microphone privacy settings panel with 'Microphone access for this device is on' toggle enabled](/files/rtCXXiNXvnoOKHB815NM)
3. Scroll further down the page and make sure that desktop apps have access to the microphone\
   ![Microphone privacy settings showing 'Allow desktop apps to access your microphone' toggle in enabled state](/files/gk9YU2znHI4WsKusoaZL)
4. If you scroll down the page a little further, you should see "KinectService.exe" as one of the apps which is allowed to access the microphone

#### Check for old Kinect SDK's or runtimes installed on your PC

Old Kinect SDK's or runtimes can prevent the Kinect camera from working correctly.

To check for and remove old Kinect SDK's or runtimes:

1. Press Windows key and type "Add remove programs" and open that application\
   ![Windows search showing 'Add or remove programs' option for accessing applications and features management](/files/uiqz5zmqo7Qi4lEPxHYA)
2. Type "Kinect" into the "Apps & features" search box. You may see no entries at all, or you may see one or both of these apps\
   ![Apps & features search results showing Kinect-related applications that can be uninstalled](/files/4VOHaTEOmznvGLmEqUwK)

If you see any other Kinect apps (e.g. older SDKs or runtimes), you should uninstall them

#### Manually install Kinect runtime

When you plugin a Kinect camera for the first time, Windows should install all of the necessary software to work with the Kinect automatically.

If something has gone wrong with that process, you can manually install the latest Kinect Runtime.

1. First, check for and remove old Kinect SDK's or runtimes (see the previous section)
2. Download the [latest Kinect runtime (v2.2.1905)](https://www.microsoft.com/en-us/download/details.aspx?id=100067)
3. Follow the install instructions from that page, by clicking to expand the "Install instructions" section\
   ![Microsoft download page showing expanded 'Install Instructions' section for Kinect Runtime installation](/files/rsMC786iizJ0EZ2G1G6H)

> **Warning:** Note - you actually need to follow the install instructions above - resist the temptation to just run the installer from the downloaded zip file!

4. If the Kinect still isn't connecting, reboot your computer at this stage and try again
5. If you still see "Kinect connected" with a green tick in Kinect Configuration Verifier after a reboot, but "Verify Kinect Software Installed" is a red cross: the next step is to install the remainder of the KinectRuntime manually
   1. Open the folder where you extracted the KinectRuntime-v2.2\_1905.zip in the previous step
   2. Run each of the "vcredist" executables in turn:\
      ![File explorer showing multiple Visual C++ Redistributable (vcredist) executable files for manual installation](/files/4T0yhEeW07Bkruoxur1l) (if you get the option to "Repair Uninstall Close", choose "Repair)
   3. Lastly, run the Kinect runtime installer:\
      ![Kinect Runtime installer executable file ready for installation to complete the setup process](/files/it8nJh747UIMz0MUGS9J)
   4. After running that, you should see:
      1. Green tick for "Verify Kinect Software Installed" in the Kinect Configuration Verifier
      2. If you run "Services" app, you should see Kinect Monitor service running:\
         ![Windows Services application showing Kinect Monitor service running successfully in the services list](/files/7b8p7DT5rzggPjIcXcPX)
      3. If you search "Kinect" in the "Apps & Features" search box, you should see the proper Kinect runtime listed:\
         ![Apps & features showing properly installed Kinect Runtime listed among installed applications](/files/NPyJqMuBKnVNU6EC3A0H)

### Verify that you have the correct driver version installed

Run Device Manager and click on Windows Sensor Devices. You should have one device listed, right-click on it and choose "Properties":

![Windows Device Manager showing Kinect sensor under Windows Sensor Devices with right-click properties menu](/files/4tTLfgWtcRv6uqZoxhwJ)

Then click on the Driver tab:

![Kinect device properties dialog showing Driver tab with version 2.2.1905.16000 and driver details](/files/na8gIKSYB9SvM5orVIoI)

*Kinect driver details*

You should see that the Driver Version is 2.2.1905.16000. If not - click on Update Driver and try to update to this version.

### If the Kinect disconnects after more than 15 seconds

Run Control Panel and search for "Power Options" then click "Change power saving settings". Click "Change plan settings" then "Change advanced power settings", you should see this window:

![Windows advanced power options dialog with High performance plan selected and USB/PCI settings expanded](/files/wpk9Ak6C2aYCkHadssVy)

*Advanced power options*

Change the plan to "High performance". If that doesn't help, you can also experiment with changing the USB settings and PCI express settings.


# Velogic Studio Pro: The Installation Session

Step-by-step preparation guide and procedures for the guided remote installation session for Velogic Studio Pro with Femto Mega cameras.

Velogic Studio Pro requires a guided installation session, where our technician will take control of your computer to complete the installation.

This is Stage 2 of the [Velogic Studio Pro (Femto Mega) - Purchasing FAQ](/section-01-getting-started/pro-femto-mega-faq).

## Preparation: before the installation session

You should have already ordered and received the necessary hardware, specified in "Stage 1: The Gathering" from the purchasing FAQ.

Before the installation session you need to gather the necessary hardware and get it plugged together, so that our technician can complete the software installation during the installation session.

Here's what you need to do:

### Prepare the PoE network switch

1. Unbox the PoE network switch, and plug it in to power.
2. Run a network cable from the PoE network switch to the spare network port on the computer. If the PoE network switch has both powered and unpowered ports, you can plug the computer into an unpowered port.

### Prepare the sync hub

1. Unbox the Orbbec Sync Hub pro
2. Plug it into power via USB-C (note that the USB-C power source isn't supplied with the sync hub; if you have a spare USB-C phone charger, you can use that, otherwise here's an [example from Amazon](https://www.amazon.com/Charger-Adapter-Charging-Android-Samsung/dp/B08M6D7LXM))
3. Set the power switch on the front to 5V

### Prepare the first Orbbec Femto Mega camera (Primary)

1. Unbox the first Femto Mega camera, and place it in the desired location in your fit area. You might use a camera tripod or wall mount; see [Setting up the fit area](/section-01-getting-started/setting-up-fit-area)
2. Plug a network cable into the Femto Mega camera, and run it to the PoE network switch. If the PoE network switch has both powered and unpowered ports, ensure you're plugging the camera into a powered port.
3. Attach the sync adaptor to the back of the Femto Mega camera, by plugging in the 8-pin adaptor to the socket.
4. Run a second network cable from the sync adaptor to the "Primary" port on the front of the sync hub (the same side that has USB-C power)

### Prepare the second Orbbec Femto Mega camera (Secondary)

1. Repeat the setup from the Primary camera (above), EXCEPT when running the network cable from the sync adaptor to the sync hub, you should plug it into one of the "Secondary" ports on the back of the sync hub.

### Schematic

If you're a visual thinker, here's a network diagram that shows conceptually how everything plugs together.

![Network schematic diagram showing connections between PC, PoE switch, sync hub, and multiple Femto Mega cameras with cable routing](/files/EV5GKz0RCxhXHtHDOTRP)

### Tips & tricks

* Although the sync system utilises network cables, the sync cables don't plug into the network switch! The sync cables plug into the sync hub.
* There is no cable going from the sync hub to the computer. This is fine! The way sync works is as follows:
  * Velogic Studio will configure the cameras so that they know whether they're the primary or a secondary
  * For each frame, the primary camera will send a sync pulse to the sync hub,
  * The sync hub will amplify & send that same sync pulse to the secondary cameras,
  * Each secondary camera will time their frame captures from that.
* If you have a labeller, it will really help to label the end of each cable, so you remember where it plugs in if it ever gets unplugged.

### Show off your setup!

1. Pull out your phone and take a quick video of the connections from the back of each camera, and the connections to the network hub and the sync hub. Email it to <support@velogicfit.com>; we'll review it and if we see any issues we'll be in touch to help you resolve them prior to the installation session.
2. Please also run the "System Information" app on your computer, and either email us a screenshot of the first page, or click File -> Export and email us the exported text file. This will help us to verify that the computer meets the minimum specs, so you have a good experience with Velogic Studio.
3. Please ensure that your computer has English language pack installed, as our technician will require that in order to complete the install.

## Book the installation session

Once the hardware is assembled and plugged together, you can book a time with our technician.

Simply visit the [booking link](https://calendly.com/velogic-darren/velogic-studio-pro-install) and choose a time slot that's convenient for you. You'll be asked for a WhatsApp phone number for us to call you on when the session starts.

## Attend the installation session

1. 24 hours before the scheduled installation, you'll be sent an email with a link to download a remote support application. In case that didn't arrive, you can download the remote support application from [here](https://vlgc.io/quicksupport); make sure you run it after it downloads.
2. At the scheduled time, our technician will call you on the WhatsApp number you provided when you booked the session.

If anything is unclear, please don't hesitate to get in touch via <support@velogicfit.com>.


# Self-install procedure for Orbbec Femto Mega cameras

Complete DIY installation guide for configuring Orbbec Femto Mega cameras with Velogic Studio Pro, including network setup and FrameBlaster installation.

This procedure is an alternative to booking an installation session, if you prefer to do-it-yourself. We would prefer to complete the installation session ourselves (remotely), so that we can verify you have a working installation - but if you insist, here's what you need to do.

> **⚠️ Warning**
>
> Note that there's a risk that if you perform this procedure incorrectly, you might get your camera into a state where it needs to be shipped to Velogic for resetting. Be aware that you will need to pay for return shipping of your camera to our HQ in New Zealand in that case!

## Verify your hardware setup

Check that you have your hardware connected and configured as per the [Installation Session](/section-01-getting-started/pro-installation-session) documentation.

## Configure the network connection in Windows

Physically locate the network cable which goes from your computer to the PoE network switch, and unplug it. (We'll plug it in again soon, but starting unplugged helps us positively identify which one it is).

Click the Start button (or hit the Windows key) and type "View network connections". You should see an entry in the start menu like this:

![Windows Start menu showing 'View network connections' search result for accessing network settings](/files/8l6KIn8J8ByJdwNzX5Vv)

... click it to see all the network connections on your computer.

Locate the network connection which is connected to your PoE network switch. You should be able to figure out which one it is, because it's a wired connection (has a picture of an RJ45 plug) and it's not connected to anything (has a red X symbol and says "Network cable disconnected":

![Network connections panel showing disconnected wired connection with red X indicating 'Network cable disconnected'](/files/0gpeMO3OjMd6abUZ0Wm8)

Now plug in the ethernet cable from the PoE network switch to the computer, and after a short time the icon should change on that network connection:

![Network connections panel showing successfully connected wired network connection without red X symbol](/files/2u0z43PDmZNe95p6lGq9)

Because we plugged in the cable, and the red X disappeared, we can be sure we've got the correct port. Click on this network connection and click the Rename button in the menu bar above it, then rename the network connection to "Velogic", to help with future troubleshooting:

![Network connection being renamed to 'Velogic' using the rename button in the network connections interface](/files/jn0SnkmaVERLvfIstYvg)

Now right-click on that network connection, and click Properties:

![Right-click context menu on network connection showing Properties option for accessing network settings](/files/DUFK8SkuiJPCiqXCCA2K)

Then click IPV4 and click Properties:

![Network connection properties dialog showing IPv4 settings option selected for configuration](/files/QoHNovwyKHFNlEdaaSaQ)

Then click on "Use the following IP address:" and type in 192.168.1.1, and press the Tab key (the Subnet mask will be entered automatically when you press the Tab key):

![IPv4 properties dialog with manual IP address 192.168.1.1 entered and subnet mask automatically configured](/files/nkU4Y9wNS5yACdvXMjnu)

Now click OK and then click Close on the underlying dialog window.

## Install the Velogic Frameblaster software onto each of the Orbbec Femto Mega cameras

Each of your Orbbec Femto Mega cameras will need to have a different IP address assigned to it during this procedure. We recommend that you use the following IP addresses:

* **172.16.1.11** for the first lateral camera
* **172.16.1.12** for the second lateral camera (if any)
* **172.16.1.13** for the frontal camera (if any)

To help with future troubleshooting, you should label each camera with the IP address you're going to assign to it. You could use a label maker, or just some tape and a marker pen.

Once you've completed the labels, we'll get Velogic Studio ready to install the Velogic Frameblaster software onto the cameras:

1. Run Velogic Studio and sign in.
2. Press the F12 key on your keyboard. This will open a small modal window; click on the tab "Orbbec Tools" and then maximise that modal window.
3. In the section labelled "Velogic Frameblaster Installer", click the INSTALL button:

   ![Velogic Studio Orbbec Tools window showing FrameBlaster installer section with INSTALL button ready to download software](/files/VuKeiOGS9ozsMeKGu2jL)

   You will see the status change to a progress bar. Wait until it has finished downloading; it should look like this:

   ![FrameBlaster installer showing completed download progress with ready status for camera installation](/files/y7rb9MDIZHfCHRSDXb9g)

   ... at this point, the Frameblaster installer has been downloaded to your Windows computer, ready for installation to your camera(s)

Repeat the following procedure for each camera:

1. Unplug any other cameras apart from the one you're setting up
2. Plug in the camera you are setting up and wait for the light on the front to be solid white
3. In the Velogic Studio Tools window, click the REFRESH button in the Network section:

   ![Network section in Velogic Studio Tools with REFRESH button highlighted for detecting available network connections](/files/YGqjje1VKWDCe1WCzsK8)
4. You should see a list of network connections. Find and click the one which has IPv4 Address of 192.168.1.1\
   ![Network connection list showing IPv4 address 192.168.1.1 connection selected for camera installation](/files/wm1LmmtHqhL9qVujBrTI)
5. Click the "SCAN" button on the section labelled "Orbbec Cameras (Factory)":

![Orbbec Cameras Factory section with SCAN button to search for available cameras on the network](/files/walC1mfukZvTbASkzAjc)

... you should see a single line returned:

![Scan results showing single Orbbec camera detected and listed for FrameBlaster installation](/files/jjkcZiE348ymVYFkfzz4)

6. Click on that line (it will turn blue) and then click "INSTALL FRAMEBLASTER":

   ![Selected camera row highlighted in blue with INSTALL FRAMEBLASTER button ready to begin installation process](/files/f0PxNRghWDAETXKhi3ge)
7. You'll see a window asking for the IP address to set on the camera:

   ![IP address input dialog prompting for camera IP address configuration during FrameBlaster installation](/files/HzvCvWerIWQ5nJgS3pKc)

   Complete the IP address to match the label you added to the camera, and click "DONE".
8. You'll see the status message change:

   ![FrameBlaster installation progress window showing active installation status and warning not to interrupt](/files/qi8e7t7q44x1igcm6Gxz)

   > **⚠️ Warning**
   >
   > DO NOT INTERRUPT the process at this stage. Don't interact with the computer and don't do anything with the camera.
9. After around a minute you should see the status message change to this:

![Completed FrameBlaster installation status showing successful completion message](/files/tPS1UJA6T45w8kaEprFj)

... it's now safe to interact with the computer again!

10. Wait for the camera to reboot and the white LED light up on the front.
11. If you have more cameras to install, you should unplug this camera and repeat the process (from step 1 above) for the next camera. Once you have completed this process for all cameras, move on to the section below.

## Reset the IP address of the network connection

Follow the same procedure as the earlier section "Configure the network connection in Windows" to set the IP address of the Velogic network connection to 172.16.1.1 (you don't need to do the unplugging and replugging step).

In summary:

1. Search Windows for "View network connections" control panel app
2. Right-click on the Velogic network connection and choose Properties
3. Click on IPV4 and click Properties
4. Enter the IP address: **172.16.1.1** (NOTE that this is different to the IP address you gave to any of the cameras; here we are setting the IP address of the computer on the network, so that it can communicate with the cameras on their new IP addresses).
5. Click OK on that dialog and CLOSE on the dialog underneath.

## Add the cameras to Velogic Studio

If the Tools window is still open, close it.

Plug in all of your cameras and wait for the LED lights on the front to all be turned on.

Repeat the following process for each camera:

1. In Step 1 of Velogic Studio, click "Add network camera":

![Velogic Studio Step 1 interface with 'Add network camera' button for connecting installed Femto Mega cameras](/files/fELLMNNPJKJwHalPeAfU)

2. Type in the IP Address of the camera (per the camera's label) and click CONNECT:

![Camera connection dialog with IP address input field and CONNECT button for adding network camera](/files/kD5xUijSc90QmvgQsGwM)

3. You'll initially see "Waiting for camera):

![Camera connection status showing 'Waiting for camera' message during initial connection process](/files/1IdmoKW6Lmt1ffJ65KB2)

... but that should quickly change to show that the camera is connected and available:

![Successfully connected Femto Mega camera showing live preview and configuration options in Velogic Studio](/files/YD0frhiQQ7UyWKfjDMXj)

4. Repeat this process from step 1 above for any other camera

## Configure the Sync system

The Sync system prevents the laser from one camera affecting the depth readings from another camera. Here's how it works:

* The camera configured as "Primary" will send a voltage pulse down the sync cable every time it fires it's laser (i.e. for every depth frame)
* The voltage pulse travels down the sync cable to the "Primary" input on the front of sync hub
* The sync hub boosts the voltage pulse and sends it out to any other cameras which have their sync cables connected to any of the output (secondary) ports on the back of the sync hub.
* The secondary cameras are configured as "Secondary 1", "Secondary 2", or "Secondary 3". The difference is that each will wait a different amount of time from receiving the sync pulse before firing its own laser to capture its own depth frame.

So, to setup the Sync system:

1. Choose which camera will be the Primary camera. How do you choose?
   * Pick a camera that's always going to be on. If you have a frontal camera, and you don't use it for some fits, then it's not a good choice for the primary camera
   * Pick a camera that's relatively close to the sync hub. If your sync hub cable is longer than 5m, that camera's not a good choice for the primary camera
2. Go into the Sync settings for that camera and set it to Primary
3. For each of the other cameras, go into their sync settings and set them to a different Secondary number (Secondary 1, Secondary 2, Secondary 3).

Note that whenever you change the sync mode of a camera, it will reboot and take around 20 seconds to come back online.

If you get a blinking orange light on the front of a camera, this means that it is configured as a secondary camera but it's not receiving a sync pulse. Check that the sync cables are plugged into the correct ports on the sync hub, and make sure that the primary camera is running.

## Post-install checks

1. Go to Step 2 in Velogic Studio and adjust the slider at the bottom-right of the liveview so that you can see all your cameras onscreen at once
2. Check that they all have GOOD framerate. If not:
   * Check that the CPU is not overloaded (make sure your computer meets the minimum specs)
   * Check that the PoE Network switch is definitely gigabit ethernet
   * Check that you've used good quality network cables
   * Go through the [Orbbec Femto Mega troubleshooting guide](/section-01-getting-started/femto-mega-troubleshooting)
   * [Book a remote support session](/section-01-getting-started/sharing-with-support#sharing-your-screen-so-we-can-help-you-in-a-live-support-session) with our technical team.


# Configuring Orbbec Femto Mega camera

Configuration options and settings for Orbbec Femto Mega cameras in Velogic Studio, including placement, sync, and image quality settings.

During the installation session, our technician will have installed the Velogic FrameBlaster software onto your Orbbec Femto Mega camera, and added the camera to Velogic Studio.

Step 1 of Velogic Studio will show a card for the camera, and you can use that card to configure the camera to work best in your studio.

On the right of the card are the settings for the camera:

![Velogic Studio camera configuration interface showing settings panel for Orbbec Femto Mega camera with placement, orientation, capture options, and quality indicators](/files/IP2jPozv0ZJkbTMkAIqE)

* **Placement** is either Lateral (for a camera placed to the side of a rider) or Frontal (to use the Aero module - only available with a Pro subscription)
* **Orientation** allows you to rotate the camera on its mount; this is mostly useful for Aero, where the camera should be mounted in a portrait orientation (because the frontal view of the rider is naturally taller and thinner, which fits the aspect ratio of a camera when mounted rotated 90 degrees). This option is less useful for lateral cameras, because the view area is constrained to be square anyway.
* **Capture knee track** allows you to choose whether the knee track is calculated and displayed on the live view.
* **Include skeleton on report image** allows you to choose whether you wish the lateral images in the report to have the blue skeleton drawn on them.
* **Create 3D view** option does additional processing to produce a 3D view option. This gives you a "3D" selector on the liveview in step 2, useful for showing customers what the camera is seeing in 3D. If you turn this on, check that your frame rate is still good, and that your CPU usage isn't too high.
* **Use depth filter** option will use the depth information from the camera to de-emphasize the background of the scene. This can be useful if you have a very busy/distracting background.
* **Joint markers**: use Eight joint markers to get advanced ankling metrics (see also: [Joint marker placement](/section-02-using-velogic-studio/joint-marker-placement))

## Image settings

Click + to expand the image settings section:

![Camera image settings panel showing exposure mode, white balance, sharpness, saturation, contrast and powerline frequency controls](/files/XtdBRukVU2UDq6v82rQe)

* **Exposure mode** is either Auto (allow the camera to select appropriate exposure) or Manual. If you have good lighting, you can leave this at Auto; if you have poor lighting, you may want to set this so Manual and fine-tune it. Low exposure = low motion blur on the colour image; the best way to get low exposure is with good lighting and Auto exposure, but if you set to Manual you can explicitly reduce the exposure time, and compensate for the darker image by turning up the brightness. There's no free lunch though: the image will be grainy.
* **White balance, sharpness, saturation, contrast**: all as per normal videography.
* **Powerline Frequency**: Set this to match the powerline frequency in your country, to reduce the flicker in the image.

## Sync settings

![Sync settings panel displaying sync mode configuration options for camera coordination system](/files/LgYdtX0Y1zzw59SHrdzd)

The Sync mode defines how the camera participates in the Sync system, which ensures that the laser from one camera doesn't interfere with the sensors in another camera.

For more information on the sync system, see the Self-install procedure for Orbbec Femto Mega cameras.

## About

The About panel gives information about the version of different camera-related components:

![About panel showing version information for FrameBlaster software, firmware, and camera hardware components](/files/122VjbZ8OIf7Ajw40j7T)

* **FrameBlaster** shows the version of the Velogic FrameBlaster software installed onto the camera. If you see an "Update" link next to this version number, you can click it to update the FrameBlaster version from Velogic Studio. For information on what's new, see the Release notes: FrameBlaster.
* **Firmware** shows the version of the firmware that the device shipped with. We can't currently update this from Velogic Studio.
* **Hardware** shows the version of the camera hardware.

## Quality Indicators

![Quality indicators showing frame rate and detection status with Good performance ratings](/files/LU08HgI0l4mFSJmqXVHM)

These show your frame rate (should always be "Good") and detection (should be "Good" if you have a rider with joint markers in view of the camera)

See also: [Lighting & environment](/section-01-getting-started/lighting-environment#Quality_indicators)

## Deactivate and Remove buttons

![Camera control buttons showing Deactivate and Remove options for managing camera connections](/files/mlq4y7l4TArqF0MrchgW)

* **Deactivate** will temporarily disconnect the camera from Velogic Studio, but still remember it's there. You can reactivate it once deactivated by clicking Activate. This is useful if you don't want to use every camera for every fit.
* **Remove** will remove the camera completely from Velogic Studio.


# Troubleshooting Orbbec Femto Mega camera

Diagnostic guide for resolving Orbbec Femto Mega camera issues, including indicator light interpretation and sync system problems.

Velogic Studio Essentials and Velogic Studio Pro can utilize the Femto Mega camera from Orbbec, which looks like this:

![Orbbec Femto Mega camera device showing its compact design with front-facing sensors and indicator lights](/files/Bbz8Amnz6fSoDGuaE77C)

You can think of this camera as a miniaturized version of the Kinect, with an on-board CPU. It is connected to your PC via an Ethernet cable, which also supplies the power to the camera. If you have more than one Femto Mega camera, you'll also have a second Ethernet cable which provides the sync signal to the camera.

## Indicator lights

You can check the indicator lights to help determine whether the camera is functioning properly.

### Front LED

![Close-up view of Femto Mega camera front LED indicator light used for status monitoring](/files/ppaES7t34g6YfxJlVuBe)

| LED status      | Meaning                 |
| --------------- | ----------------------- |
| Solid white     | On and ready            |
| Off             | Off (or booting up)     |
| Blinking orange | Waiting for sync signal |

Note that "Solid white" means that the device has power and the onboard CPU is running; it does not necessarily mean that the sensors in the camera are active and streaming. You can check the front laser (below) to see if the sensors are active.

If the indicator is "Blinking orange", that means that the camera is configured to be a Secondary camera (in the Sync settings in Velogic Studio). As a Secondary camera, it will only run when it receives a Sync signal from the Primary camera. Steps to troubleshoot this:

* Check that you have the Primary camera configured as a Primary in Velogic Studio
* Check that the Primary camera is running (Front LED is on, and Velogic Studio is receiving frames from it)
* Check that you have sync cables from both the Primary and Secondary camera going to the Sync Hub
* Check that the Sync Hub has power (via USB-C adaptor)
* Check that the Primary camera's sync cable is going into the front of the sync hub (the side with only 1 RJ45 jack)
* Check that the Secondary camera's sync cable is going to one of the 8 ports in the "Secondary" group on the back of the sync hub

### Front laser

This is not strictly speaking an indicator LED; it's the actual laser that the camera uses to emit the light pulses which are then received onto the depth sensor to determine depth in the scene.

![Front laser emitter on Femto Mega camera showing the structured light pattern used for depth sensing](/files/9vFOOd2WqSno02ygBZIx)

You'll be able to see this laser as a red light that appears to have "structure".

The laser should only be on when the camera is active and streaming data to Velogic Studio.

We recommend that you turn the power to the whole camera off overnight, just in case the camera gets into a state where the laser is running when not needed.

### Rear LED

The light at the rear of the camera will be the first one to give any indication as the device boots up.

| LED status     | Meaning            |
| -------------- | ------------------ |
| Solid white    | On and ready       |
| Off            | No power to device |
| Blinking white | Booting            |

## If the camera regularly disconnects and reconnects

... the most likely cause is the sync system, either because the sync cables aren't high quality OR the sync hub isn't getting USB power.

**Quick fixes:**

* The voltage switch on the Sync Hub should be set to 5V, and you should see a blue light beside the voltage switch. If you don't see the blue light, try a different USB power adaptor (make sure it **isn't** marked as "PD") and/or USB-C cord.
* Try a higher-quality and/or shorter cable for the primary and secondary sync cables.
* If you have one cable that's longer than the others, make that a secondary camera. The sync pulse which is output from the Sync Hub seems better able to travel longer distances than the sync pulse from the camera itself.

If those quick fixes don't work, here's a longer procedure to confirm that the sync system is actually the cause of the problem:

1. Watch the light on the right-hand side of the face of the camera.
   * If it is consistently blinking orange, that means it's configured as a Secondary (so it's waiting for a sync pulse) but it's not getting the sync pulse
   * If it starts out white, but then blinks orange, and then repeats that cycle: this means the camera gets an inconsistent or poor-quality sync signal. This causes an internal error in the camera, so it reboots and tries again.
2. Unplug the Sync cable from the pigtail adaptor at the camera
   * The camera should now stop the disconnect/reconnect cycle in Velogic Studio (or at least, the disconnects should be less frequent and take only a second or two each time).
   * You should see the configuration options, but no video feed from the camera:

     ![Velogic Studio camera card showing configuration options but no video preview when sync cable disconnected](/files/v9kQYyLuMXIbT4Qr4cVq)
   * The light on the front of the camera should be blinking orange, because it can't get any sync signal at all.
3. Change the Sync settings to make the camera Standalone (so it's not waiting for a Sync signal anymore):

   ![Camera sync settings panel with Standalone mode selected to disable sync signal dependency](/files/QNv7uPEasMYkdpRVC2b5)

   * The camera will restart, and after about 30 seconds you should get a solid video feed from the camera.

If you do now get a solid video feed from the camera, after switching it to Standalone mode, **you've successfully confirmed that the Sync system is the issue**.

You can use Velogic Studio in this state; there is a small chance that the cameras will interfere with each other (because the sync system is not working), but the chance is small and the system will still be useable while you are fixing the sync system.

### How to fix the sync system

* Check that all of the cables used in the sync system are high-quality **Cat6 or Cat6a** cables. This includes the cable from the primary camera to the sync hub, and from the sync hub to all secondary cameras.
* Try shorter cables, even if that means running a cable directly across the floor rather than routed through the walls
* Check that the sync hub voltage switch is set to 5V
* Check that the sync hub has 5v power (the sync hub doesn't ship with a USB-C power adaptor, but it needs one). To check this, you can temporarily set the voltage switch to 5V, and the LED light next to the switch should turn on. If the LED light does not turn on, double-check the USB-C power adaptor or try another one. Note that USB-C power adaptors marked as PD (Power Delivery) will not work with the sync hub.

## Low frame rate

There are several possible causes of low frame rate from an Orbbec Femto Mega camera. Work through the following list to identify and resolve the issue.

### Power-cycle the camera

As a first step, power-cycle the camera by unplugging it from its Ethernet cable, waiting about 10 seconds, and plugging it back in. Wait about 30 seconds for the camera to boot and reconnect to Velogic Studio. This clears any temporary state that may have caused the camera to misbehave.

### Bad network cable

The Ethernet cable connecting the camera to your network switch may be too long or of insufficient quality. This can cause dropped frames or inconsistent data transfer.

**Diagnosis:** Replace the cable with a shorter, higher-quality Cat6 or Cat6a cable and see if the frame rate improves.

If you have more than one camera and only one has low frame rate, try physically swapping the two cameras so that each camera uses the other's cabling. If the problem follows the cabling (i.e. the other camera now has low frame rate), the cable is the issue.

### Sync system

If the camera with low frame rate is configured as a Secondary, it waits for sync pulses from the Primary camera via the Sync Hub before firing its own laser. If those pulses don't arrive reliably, the camera can't maintain a steady frame rate.

**Diagnosis:** Change the camera's Sync setting to **Standalone**, and wait for it to reconnect. If the frame rate is now good, the sync system is the cause.

To fix the sync system:

* Use shorter, higher-quality **Cat6 or Cat6a** cables for all sync connections
* Check that the Sync Hub voltage switch is set to **5V** and the LED beside the switch is on
* Check that the Primary camera's sync cable goes to the front of the Sync Hub (the side with only 1 RJ45 jack)
* Check that Secondary cameras' sync cables go to the "Secondary" group on the back of the Sync Hub
* Make sure the Sync Hub's USB-C power adaptor is **not** marked as "PD" (Power Delivery)

### Network switch

Not all network switches can handle the volume of data from Orbbec Femto Mega cameras, especially when running multiple cameras simultaneously. We recommend the Ubiquiti UniFi switch because it is known to reliably handle the full traffic from up to 3 cameras. Other switches may claim compliance with the required network standards but fail to cope under sustained load.

If you are using a different switch and experiencing frame rate issues, try replacing it with the recommended [Ubiquiti 8-port switch](https://www.amazon.com/Ubiquiti-Switch-Gigabit-802-3at-USW-Lite-8-PoE/dp/B08KC6KT1F).

### Shared network port

Each Orbbec Femto Mega camera generates a large amount of network traffic. If your cameras share a network port with other traffic (such as your office LAN), this is not a supported configuration and will likely cause frame rate issues.

Make sure your cameras are connected to a dedicated Ethernet port on your computer. If you don't have a spare port, you can add one using a [USB-to-Ethernet adaptor](https://www.amazon.com/USB-Ethernet-Adapter-Gigabit-Switch/dp/B09GRL3VCN) — it must be **Gigabit** (1 Gbps) rated.

### Computer performance

If your computer doesn't have enough processing power — particularly when running 3 cameras — it will drop frames.

**Diagnosis:** Open Task Manager while Velogic Studio is running (press **Ctrl+Shift+Esc**), and click the **Performance** tab. Watch the CPU usage graph. If CPU usage is consistently above about 70%, the computer is likely struggling to keep up.

Another sign is if frame rate is fine with one or two cameras, but degrades when you add a third.

**Quick fix:** In Velogic Studio, go to the camera configuration panel (Step 1) and check whether **Create 3D view** is turned on. If so, turn it off — this option uses significant CPU and is not needed during normal fitting sessions.

**Solution:** If CPU usage is still too high after turning off the 3D view, upgrade to a higher-spec PC. See our [PC System Requirements and Compatibility Guide](/section-01-getting-started/pc-system-requirements) for minimum and recommended specifications.

### Third-party antivirus with network protection

Some third-party antivirus software includes network protection features that attempt to scan all network traffic. The high volume of data from Orbbec cameras can overwhelm this scanning, causing frame drops. McAfee is a known example.

The built-in Windows Defender does not cause this issue.

**Solution:** Uninstall the third-party antivirus software. Windows Defender provides sufficient protection and does not interfere with camera traffic.

## Getting help

If you've tried the troubleshooting steps above and are still experiencing issues, you can [book a remote support session](/section-01-getting-started/sharing-with-support#sharing-your-screen-so-we-can-help-you-in-a-live-support-session) with our technical team.


# Signing in - troubleshooting

Solutions for common sign-in problems including password issues, license validation, and offline usage for Velogic Studio.

Velogicfit's windows applications, Velogic Studio and 3D Aero, require you to sign into your Velogicfit account when the application starts. If you're having trouble signing in, this guide will help you to resolve your issue.

## How does the sign-in process work?

The purpose of the sign-in process is to obtain a license file for your velogicfit application. When you run a velogicfit application, it checks your computer for a license file to ensure that you're a valid user of that application.

It will also try to sign into Velogic servers, to obtain a fresh license file. It can sign in automatically by continuing your previous session, or it can prompt you to enter a username and password.

* If it can sign in automatically from your previous login, and can get a fresh license file, you won't even see the sign-in window - you can just start using the application.
* If it can't sign in automatically, you'll be asked for a username and password.
* Even if you can't sign in (e.g. because you're travelling somewhere without an internet connection), you'll see an option to "Use Offline" for up to 5 days after the last time you signed in and obtained a new license.

The remainder of this document deals with sign-in troubleshooting scenarios.

## Problem: You can't remember your password

That's an easy one. You can easily reset your password via our website: <https://app.velogicfit.com/login?reset>

## Problem: You get "Invalid username or password" message when you try to sign in

![Velogic Studio sign-in dialog showing 'Invalid username or password' error message with input fields](/files/EAOKp4rk8lzCp4gTwlGn)

If you see this message on the sign-in window, most likely you have made a typo in either your username or password.

* If you think that they're definitely correct, but not being accepted: try signing in to the velogicfit website [app.velogicfit.com](https://app.velogicfit.com) using the same username and password. If you can't sign in to the website either, you may need to reset your password.
* If you can sign in successfully from our website, but not from your Velogic Studio or 3D Aero application - you may need to allow Velogic Studio or 3D Aero through your firewall. If you don't know how to do that, please get in touch with us and we'll help.

## Problem: You get "Could not obtain a valid license" message

This means that you were able to sign in, but our servers couldn't create a valid license file for your application - most likely because you don't have a valid subscription.

You can check your subscription status via [our website](https://app.velogicfit.com/plans), or get in touch with us.

## Problem: You're going to be offline for a few days

This is not actually a problem. Velogic Studio is designed to allow you to work offline (without a new license check) for up to 5 days.

1. While you still have internet access, run Velogic Studio and sign in as normal.
2. Go offline and run Velogic Studio again. You should see a "Use Offline" option at the bottom of the sign-in window:

   ![Sign-in dialog with 'Use Offline' button option available at bottom for working without internet connection](/files/DUvKjuoC1Tdz6HlMgwmq)
3. Click "Use offline", and you should be able to use Velogic Studio as normal.


# How to share things with Velogic support

Comprehensive guide for sharing fit sessions, replay files, performance data, and other diagnostics with Velogic support for troubleshooting.

If you are having problems with any aspect of Velogic Studio, there are often things you can share with us so that we can help you troubleshoot. This page lists out the various different things you can share, and when it's appropriate to do each.

## Sharing a whole fit session (to troubleshoot strange results or report issues)

If you've completed a fit and seen something strange in the results or the report, you can share the whole fit with us.

1. Run File Explorer and navigate to the "Velogic Studio Fits" folder (inside "My Documents" folder)
2. Find the fit you would like to share with us
3. Right-click on the folder and choose "Compress to ZIP file"

   ![Windows File Explorer context menu showing 'Compress to ZIP file' option for creating compressed fit session archive](/files/4YKpNhumKU1fQzT4Mqi9)
4. In your browser, navigate to <https://vlgc.io/upload>
5. Click the "Select Files" button:

   ![Velogic file upload webpage with 'Select Files' button for uploading fit session data to support team](/files/5wOOmeWue9QGzgKtzmPI)

   ... and navigate to the .zip file you created above.
6. You'll be asked for your name, and the file will upload. Please also send us an email (<support@velogicfit.com>) to let us know why you sent it and how we can help.

## Sharing replay files (to troubleshoot camera or marker issues)

A replay file contains a few seconds worth of the raw data produced by the camera. We can use a replay file to troubleshoot why you are having problems with marker dot recognition, or perhaps measurement with the wand.

If you are having issues with Marker Detection we have a simple process for submitting files for analysis.

Here's a video of the "Submit Sample" process:

{% embed url="<https://vimeo.com/377229580>" %}

Before you begin the process please ensure that the system has been calibrated and the bike measured (this data is saved in the file submitted and will help us troubleshoot).

When ready please click on the dropdown at the top left of the liveview:

![Velogic Studio live view dropdown menu with 'Send a sample' option for submitting camera data samples to support](/files/p4LoNaMho2X3F0DzDB5R)

Then click "Send a sample"

This popup will appear:

![Sample submission dialog explaining the process for sending camera data samples to Velogic development team](/files/UUcjsouqAFCJ9JHVhlqL)

Click "Next" for the consent form. You will need to ask the rider if they consent to their data and image being used in our development process. The files will never be shared outside velogicfit.

![Consent form dialog requesting rider permission to use their data and image in Velogic's development process](/files/2Es5Tr7O3YjZd4lpYOhG)

Click "Next" to indicate what size upload you wish to provide. Note that the minimal option can sometimes mean that we can't identify your issue. However, you will not be able to do anything else with the system while it is uploading so do not choose the full sample option if it means you will be waiting for 20mins for the upload to complete.

![Sample size selection dialog offering minimal, standard, or full upload options with time considerations](/files/gIUQjuyuqVGtJsOgpp8L)

When you have selected a sample size, click Next and finish the wizard.

If your issue is urgent, please get in touch with us to let us know that you've submitted a sample, and what the problem was.

## Sharing performance data (to troubleshoot software performance issues)

If Velogic Studio seems sluggish or you aren't happy with the performance on your computer, you can use an inbuilt tool to record and upload a performance file. We can analyse this file to see where Velogic Studio was spending most of its time, which may lead to future performance improvements.

See our docs on [Submitting performance data](/section-01-getting-started/submitting-performance-data)

## Sharing measurement data (if you get unusual measurements with the wand)

If you're using the measurement wand to take bike measurements, and you're not happy with the measurements you're getting, you can share a screenshot of your measurements plus data from the camera of the wand position at each point.

We can analyse the data and provide guidance.

To share this data with us, simply click the "Upload to support" button at the bottom of the measurements column at the end of the measurement wizard:

# Submitting performance data

Instructions for collecting and submitting performance data to Velogic support for troubleshooting system performance issues.

If you're not getting the performance you expect out of Velogic Studio, a great first step is to submit some performance data to our support team.

If our support team asks you for performance data, here's what you should do:

1. Sign into Velogic Studio as normal.
2. Get to the place in the application where you're having performance problems.
3. Press the F12 key on your keyboard. This will open the "Tools" window.

> **Note:** The "Tools" window is really for internal use, so we haven't made it look nice! Sorry.

4. Click on the "Performance" tab:

   ![](/files/OKGxEJzvo88SNq6mfs35)
5. Click the "Collect performance data" button. The first time you do this, it may take a few minutes to configure itself.
6. Eventually you should see:

   ![](/files/NfwAPtqVfzH50brsVAEg)
7. Leaving the "Tools" window open (you can move it to a different screen or make it smaller), go back to Velogic Studio and do whatever task wasn't performing well (e.g. capturing, comparing video, generating a report).
8. When you've done that task, come back to the Tools window and click "Stop collecting"

> **Note:** The performance data can be large - approximately 1MB per second of collection. If you don't have good internet connectivity, try to limit the time you collect performance data.

9. After you click "Stop collecting", it will take several seconds to prepare the data for submission. When the data is ready, you will see:

   ![](/files/1qUxQhZQBTJENNttZYhQ)
10. Click "Submit to support".

> **Privacy Note:** The data that is submitted is purely technical, telling us how long particular parts of Velogic Studio are taking to execute. It contains no user data, aside from your email address.

11. When the data has been submitted (uploaded) to our servers, the performance tab will return to the initial mode, just showing the "Collect performance data" button. You can now close the Tools window.

Our support team will be notified of the file, and will analyse it and get in touch with you via email.

Thank you for your help in making Velogic Studio awesome.


# Setting your location for find-a-fitter and Frame Comparison ads

Configure your business location to appear on Velogic's find-a-fitter map and Frame Comparison advertising

We're in business to help your business succeed. We want to help your potential customers find your service, and there are a couple of different ways we can do that.

## Find-a-fitter (all Velogic Studio users)

Our public site has a ["find-a-fitter" page](https://www.velogicfit.com/find-a-fitter), and so does the [Velogic Web Tools site](https://app.velogicfit.com/find-a-fitter). Customers can use the "Around you" function to locate themselves on a map, and see fitters near them using Velogic Studio.

## Frame Comparison ads (Velogic Studio Pro users)

Our free [Frame Comparison tool](https://app.velogicfit.com/frame-comparison) is used by thousands of people every month. We've recently (early 2024) added a small advertisement to the top of this page, which will show Frame Comparison users the location of their closest fitter. Here's how it works:

1. Someone (hopefully a keen cyclist looking for a new bike) accesses our Frame Comparison tool in their browser, via <https://app.velogicfit.com/frame-comparison>
2. Our server notices their IP address, and looks up their approximate location. (This isn't a very accurate location, but should at least tell which country they're in)
3. Our server looks for a fitter within 1000km of that location who is using Velogic Studio Pro (this is one of the differences between Velogic Studio Essentials and Velogic Studio Pro product levels)
4. If found, the server will insert a small ad at the top of the Frame Comparison page, like this:

   ![Frame Comparison tool webpage showing advertisement banner for finding nearby bike fitters](/files/vKkKsZz0iffpYgcaIcs0)
5. The user can click "Show details" to find basic contact details for the fitter's service:

   ![Expanded bike fitter details card showing contact information and location for a Velogic Studio Pro user](/files/gYpIcMARQkFlywAvnAHJ)

## How to set your location and profile

Before 2024, we were using a third-party shop locator which needed to be manually kept up-to-date. Unsurprisingly, it quickly drifted out-of-date, so we now have a new system which automatically syncs location and profile data which you can control yourself via our app site, app.velogicfit.com.

Here's how:

1. Go to <https://app.velogicfit.com/your-profile> (you'll need to sign in if you aren't already)
2. Fill out the first form, with details which can we use to keep in touch with you

![User profile form with fields for personal contact details including name, email, and phone number](/files/65vVH7kbSnaUq13oAD05)

3. Fill out the "Your public profile" form, which we'll use to estimate your location in the next step, and also use to provide details (email and website) in the Frame Comparison ad, if applicable:

   ![Public profile form showing business name, email, website, and address fields for fitter listing](/files/9R6OoyUfJYfo4Zrcex1b)
4. Set your geographic location via the "Your public location" form. You can click "Locate profile address" to set a pin at the location of your address from the last step. If it's not accurate, you can click on the map to reset the pin location, then click "Save"

   ![Geographic location setting interface with interactive map for pinpointing precise business location](/files/QZkltL3CmjfKcTyvIVjW)
5. Finally, upload an image of yourself or your logo (your face is better, because your customers will form a better connection with a face than with a logo)

   ![Profile image upload section with placeholder for adding fitter photo or business logo](/files/V5eiFtjmh9ozf5jq8ZqE)

### What if you don't want your location to be used for find-a-fitter and/or frame comparison ads?

No problem - simply don't set a location in the "Your public location" form. If you've already set a location but you want to remove it, simply click "Remove location".

### What if you don't want to see Frame Comparison ads yourself?

Frame Comparison ads are never served to people who are signed in and who have Velogic Studio subscriptions.

If you're a bike fitter and you're annoyed to see ads for your competition, then we're sorry-not-sorry because these tools are provided for free to the public and frame comparison ads is one small way we can capture some benefit from that for our users. We would love to welcome you aboard as a Velogic Studio user when you're ready.

# Velogic Studio v4: What's new, and how to transition from v3

Comprehensive guide to Velogic Studio v4 new features, improvements, and how to upgrade from v3

In January 2023, we announced that Paraic McGlynn at Cyclologic had taken an equity stake in Velogic and was coming onboard as CEO.

Since then, we've been hard at work building a new version of Velogic Studio which will "blow the doors off" (Paraic's words) the bike fit systems landscape.

## The journey

Based on your feedback, and Paraic's strategic vision, our major goals have been:

* Retaining Velogic Studio's ease-of-use and streamlined workflow
* Adding more analysis and visualisations to help bring the rider on the fit journey
* Better support for bilateral capture, giving visibility on how changes are affecting symmetry.
* Support for a new camera, Femto Mega from Orbbec as Kinect replacement (yes, the Kinect camera still works and is still supported too!)

Now, in January 2024, we are proud to announce Velogic Studio v4.

Because there are so many new features, we're not going to push this out through the normal upgrade channel; instead, existing customers will have 12 months to upgrade.

Read on to see what's new, and how you can transition to it.

## What's new

### Femto Mega camera from Orbbec

![](/files/ddl5e4Ke1W5SGiKus487)

This camera can be considered to be the grandchild of the Kinect for XBox One that we've used until now. A brief history of the lineage is as follows:

* Microsoft created a new Kinect camera for use in their Hololens AR glasses
* Microsoft then created a separate camera, called the Azure Kinect Development Kit (AKDK) based on the cameras in the Hololens AR glasses
* Microsoft decided not to take that new camera to market directly; instead they decided to partner with industry
* Orbbec Inc is the first company to release a camera based on the AKDK. It's called the Femto Mega, and we've been working with Orbbec to integrate it into Velogic Studio.

One of the most important features of the new Femto Mega camera is that it allows multiple simultaneous cameras connected to the PC. Further, it has onboard processing and a network port, which means we're able to use up to 4 cameras via a local network, with greatly simplified cabling compared to USB connections. In summary, this is the 3D camera we've been waiting for: it's powerful, it's supported, and we can use multiple of them!

### Visual overhaul

We've rebranded Velogic Studio to move away from the previous "skeumorphic" (3D) look and towards a simpler but more elegant look. It has also picked up a blue colour scheme and new font to align with MotionMetriq application; this is to recognise that Velogic Studio is the "spiritual successor" to MotionMetriq and ease the transition for those users.

The color scheme looks great both in dark and light themes (you can switch temporarily with CTRL+T, or go into Settings to change permanently):

**Dark theme** ![](/files/KDLwHrH3TKqa4uWQStHM)

**Light theme** ![](/files/aL9zElMV0YtCME2PGUvY)

### Left/right metrics

In Velogic Studio v3, you could rotate the rider 180° to capture metrics from both sides of the body - but it didn't keep track of which was the left, and which was the right side.

In v4, we keep track of left vs right throughout the app: ![Left/right in the Motion Metriqs panel](/files/Hu6a0bp11c4UvgfGTPRp)

![Left/Right in the grid](/files/rmsnPKrbhcyGcn3TE9ni) \[Left/Right in the grid screenshot]

![Left/Right in the report](/files/tuMkku6jWWGrYJQWa7fP)

If you're using dual bilateral Femto Mega cameras, left and right metrics are automatically calculated and stored as you complete each capture.

If you're using single-sided (e.g Microsoft Kinect), you can rotate the rider to do two separate captures, and then merge the captures into a single column.

### Support for multiple Kinect cameras (non-simultaneous)

Windows has always had a limitation of only supporting a single Kinect camera. That limitation still exists, but in Velogic Studio v4 the app lets you work with 2 different Kinect cameras - by allowing you to name them (e.g left / right), and then detect which one you've got connected as you hotswap them.

This means you can:

* Start with e.g. the left Kinect camera plugged in
* Capture the left side of the rider
* Unplug the left Kinect camera and plug in the right Kinect camera
* Capture the right side of the rider
* Then merge the 2 captures to see both sides in a single capture.

It's obviously better to be able to do this simultaneously; that's possible with 2 x Orbbec Femto Mega cameras, but unfortunately not with 2 x Kinect cameras.

### Stroke Analysis: virtual 90FPS

In the past, people have criticised Velogic Studio for only working at 30FPS (the max frame rate for the Kinect camera). We always felt that was an invalid criticism, because we were calculating angles from a number of different pedal strokes, meaning it's highly likely we captured metrics like max knee angle very close to the absolute max.

With Velogic Studio v4, we've gone one step further. The app will now automatically interweave frames from over the entire capture period (usually 15 seconds), to give a "virtual frame rate" of up to 90FPS. This means that you can "scrub" the video to see a very smooth movement of the foot.

The only downside is that if the rider is moving their head a lot during the capture, their head will appear to "flicker" in the stroke analysis view; this is easily resolved by asking them to fixate on a point ahead during the capture.

When you're reviewing a capture, it will start in "raw video" mode by default. If you want to look at the Stroke Analysis, you can simply click the "Stroke" button at the top of the review panel:

![](/files/uGFQzF2PChBaOpywEuQK)

... and you'll see a more advanced video review view, where the X axis no longer represents time; now, it represents crank angle. The data from the metric you're reviewing (in this case, min or max knee angle) is overlaid as a mini-graph on top of the scrubber, so you can see how it changes throughout the stroke:

![](/files/9U6OyhLXB09HrQsVBt1h)

### Faster review and comparison of captures

A large part of analysing your fit results is comparing the changes between 2 captures. That's now super easy, and it's all based on the capture thumbnails along the bottom of Step 2.

You can:

* Mouseover any capture to replay the videos from that capture

  ![](/files/pmAXYOu4WM3lih5gXLbL)
* Click "Lock" on the capture you've moved the mouse over, which locks it for review (so you can use the mouse to interact with the saved videos from that capture)

  ![](/files/b31pdwXOAiI7uMhm3AJu)
* After "Lock"ing one capture, you can mouse over a second one and click "Compare" to go into an analysis mode between those 2 captures

  ![](/files/MGRHYdPTHQqhxQeZWACL)

From there, you can unlock either (or both) and lock/compare others. See [Reviewing and comparing fit artifacts](/section-02-using-velogic-studio/reviewing-fit-artifacts) for more information.

### Instant visualisation of metrics

You can click on (nearly) any of the metrics on the right-hand side to see a visualisation of what it's measuring, auto-seeking to the best frame in the capture.

For example, if you've got a capture locked (see above) and you click on Knee Angle Max, you'll be taken directly to the frame from the capture which best represents that max knee angle:

![](/files/FjAXAutEFWKjrk92VUbL)

Lateral travel metrics look like this:

![](/files/HDdQpXCngLIPUMUR9tX7)

### New ankling metrics

We added an (optional) 8th marker, placed near the heel, to give a more accurate ankle angle figure (which doesn't vary with the size of the rider's foot).

If you choose to use the 8th marker, you'll see new ankling metrics in the Motion Metriqs area on the right-hand side of step 2:

![](/files/9sjxHnlMiuJstOcre8th)

If you click on one of these new metrics while reviewing a capture, you'll see a brand-new visualisation of how ankling changes throughout the stroke:

![](/files/aGMExNoAK4X10AqFzDYe)

The purple and red "bands" around the outside of the circle represent whether the ankle is plantarflexed or dorsiflexed (relative to the average ankle flexion over the whole stroke)

## Essentials vs Pro product levels

With Velogic Studio v4, we're creating 2 different levels of subscription.

* **Velogic Studio v4 Essentials** is the lower-level product. It does broadly everything Velogic Studio currently does and has access to the new analysis and visualisation technologies.
* **Velogic Studio v4 Pro** is the new higher-level product. The additional features available at this level are:
  * **Simultaneous bilateral capture** (requires 2 x the new Orbbec Femto Mega cameras)
  * **Bikefinder integration** (find suitable frames from bike measurements)
  * **3D Aero integration** (when completed, targetting Q2 2024, but no promises)
  * **Frame Comparison promotion** (fitters at this level will optionally be featured on our free Frame Comparison page, used by thousands of riders every month).

### Pricing for new users

* **Velogic Studio v4 Essentials** will cost USD$3000 per year, or USD$300 per month. After the first 12 months, customers will receive a 60% continuity discount, taking the cost to USD$1200 per year or USD$120 per month.
* **Velogic Studio v4 Pro** will cost USD$4500 per year, or USD$450 per month. After the first 12 months, customers will receive a 60% continuity discount, taking the cost to USD$1800 per year or USD$180 per month.

The continuity discount will cease when subscriptions lapse (due to repeated failed payment attempts) or are cancelled. New subscriptions will be billed without the continuity discount. This gives flexibility for people to start & stop monthly (at full monthly cost), but still be rewarded for sticking with a subscription over a continuous period.

Note that Velogic Studio 3 subscriptions included the ability to pause subscriptions for a max of 3 months in a year. The new subscriptions don't offer that feature.

### Pricing for existing users

Existing Velogic Studio (v3) have until the end of 2024 to make a choice. At any time, you can:

* Move to **Velogic Studio v4 Essentials** at your current pricing. Simply install Velogic Studio v4 from [this link](https://vlgc.io/install4), sign-in with your existing credentials, and start using it. (Note that fit sessions created/saved with v4 cannot be opened with v3, but your older v3 captures can be opened with v4), Once you're happy with v4, you can simply uninstall v3 from your computer.
* Or, move to **Velogic Studio v4 Pro** at the new pricing level. If you've already been paying for Velogic Studio for 12 months, you're eligible for the 60% continuity discount, meaning your new subscription cost would be USD$1800 per year or USD$180 per month. Contact us when you are ready to make this move; we'll set your old subscription to cancel, and send you an invoice link for the new subscription (including the 60% continuity discount, if applicable).

If you don't make a choice, we'll assume you'll want to move to Velogic Studio v4 Essentials at your current pricing level.

At the start of 2025, **Velogic Studio v3 will stop working** and you'll need to be on either v4 Essentials or v4 Pro.

## How to transition to v4

Per the pricing section above: if you're happy to stick with Essentials, simply install Velogic Studio v4 from [this link](https://vlgc.io/install4), sign-in with your existing credentials, and start using it.

Once you're feeling at home in Velogic Studio v4, you can uninstall the older Velogic Studio v3 from your computer.

If you want to move up to Velogic Studio v4 Pro, just get in touch with us and we'll talk you through upgrade options & pricing.

## Summary

We've worked really hard to not only survive Covid, but to emerge with the best bike-fit solution in the market, at a price you can afford and with options for existing users to retain your current pricing level.

Please get it touch if anything is unclear.


# Velogic Studio - "Insider" version

Information about the Insider preview build of Velogic Studio, featuring early access to new features and bug fixes.

The "Insider" version of Velogic Studio is special build which contains a "sneak preview" of features & bug fixes. It allows us to test those features and bug fixes in a range of real-world conditions before releasing into the main build.

Things to know about the Insider version:

* It can be installed alongside the main Velogic Studio - there is no need to uninstall Velogic Studio before you install the Insider version
* The Insider version will save data to the same location as the main Velogic Studio, and uses the same licensing. So if you're a valid user of Velogic Studio, you are eligible to use the Insider build.

You can tell the Insider version from the main version by the "(Insider)" suffix, which appears in Start menu:

![Windows Start menu showing Velogic Studio (Insider) entry with distinctive Insider suffix label](/files/REKBatrxwvwQbModiGxy)

... and in the title bar of the application when it's running:

![Velogic Studio application window with (Insider) designation visible in the title bar](/files/RH3P8OnZPwVJsrGGQMxV)

The Insider version is expected to be a little less stable than the main version. If you're OK with that, and you would like to get early access to features & fixes, please get in touch (<contact@velogicfit.com>)


# Release Notes - Velogic Studio (Insider)

Release notes for the Insider preview version of Velogic Studio, containing early access features and bug fixes.

These are the release notes for the Insider version of Velogic Studio.

See also: [Release notes for the main (non-insider) version](/section-01-getting-started/release-notes)

## v4.0.2935 on 2026-02-05

### Improvements

* **Best Frame Summary**: When you click a body metric, the summary value now displays on the best frame, making it easier to see key measurements at a glance.
* **Body Metric Explanations**: Metric explanations are now clearer and more consistent regardless of which sensor captured the data.

### Bug Fixes

* **Lateral Comparison Mode**: Fixed a crash that could occur when using lateral comparison mode.
* **Review Playback**: Fixed an issue where lateral ToF review playback could show stale frames from previous sessions.
* **New Plugin Activation**: Fixed an issue where newly installed plugins weren't automatically enabled for users with existing settings.

## v4.0.2892 on 2025-12-04

### New Features

* **Position name in Motion Metriqs**: The Motion Metriqs panel now shows the name of the currently locked-for-review fit log entry.
* **Position comparison in Motion Metriqs**: When comparing two positions, the Motion Metriqs panel now shows a selector to switch between Position 1, Position 2, or Delta (the difference between them). ![](/files/L5oBoT7BTiiOcZuC4Zr4)

### Improvements

* **Comparison mode headers**: Improved layout of left/right column headings when comparing positions.

### Bug Fixes

* **Calibration recovery after crash**: Fixed an issue where calibration settings would not be properly restored after an unexpected application restart. The system now correctly saves and restores calibration state.
* Several other bug fixes and stability enhancements

## v4.0.2887 on 2025-10-29

* Global playhead is here! When you're reviewing or comparing, you'll see a new playhead control in the header of step 2:

  ![](/files/8Gm0uQOTE5sRW5V5SuGs)

  ... and it controls all visual playback. You can switch between Raw and Stroke modes, and set the playback speed.
* Popout liveviews: click the button in the liveview to pop it out into a separate window. If you have multiple monitors, you can drag it to a second monitor. When you move between wizard steps, or review/compare states, the separate windows will be shown/hidden automatically. You can simply close the popped-out window to dock it back in the main Velogic Studio window.

  ![](/files/otWKdvSMzIT72uZ5XzPK)

  ... to pop out a liveview, just click the icon on the top-right:

  ![](/files/QBVUMk33vNqUJ8FVlFSZ)
* Popout comparisons: just like the liveviews, you can pop a window out from the comparison panel. And if you resize the popped-out window to be vertically oriented (taller than wide), they will "stack" vertically rather than horizontally.

  ![](/files/JsOYoOcEt1DVhFnoLhXY)
* Stroke-mode versions of frontal and webcam videos. Previously, stroke-mode was only available for lateral cameras; now, Velogic Studio will use the crank angle data from the lateral cameras to create stroke-mode analyses for webcams and the frontal (Aero) camera. Please ensure your Orbbec cameras are updated to the latest firmware (v1.5) by expanding the "About" section on your camera's configuration panel on Step 1, and clicking the "Update" button if you're not already on v1.5

  ![](/files/xAfh8CpajJilsLhl9s5q)

# Release notes - Velogic Studio

Official release notes documenting new features, improvements, and bug fixes for the main version of Velogic Studio.

## Release Notes - Velogic Studio

This section summarises bugs and features released to Velogic Studio users.

See also: [Release notes for Insider version](/section-01-getting-started/release-notes-insider)

Note that new releases of Velogic Studio are automatically delivered to your computer. You can check the version number on the top-left of the Velogic Studio window; if it is less than the latest version number below, you can simply wait a few minutes (you should see "Update is pending" when it notices a new version is available), and then restart Velogic Studio to move to the new version.

## v4.0.2935 on 2026-02-10

### Improvements

* **Best Frame Summary**: When you click a body metric, the summary value now displays on the best frame, making it easier to see key measurements at a glance.
* **Body Metric Explanations**: Metric explanations are now clearer and more consistent regardless of which sensor captured the data.

### Bug Fixes

* **Lateral Comparison Mode**: Fixed a crash that could occur when using lateral comparison mode.
* **Review Playback**: Fixed an issue where lateral ToF review playback could show stale frames from previous sessions.
* **New Plugin Activation**: Fixed an issue where newly installed plugins weren't automatically enabled for users with existing settings.

## v4.0.2892 on 2025-12-04

### New Features

* **Global playhead**: When you're reviewing or comparing, you'll see a new playhead control in the header of step 2. It controls all visual playback - you can switch between Raw and Stroke modes, and set the playback speed.

  ![](/files/8Gm0uQOTE5sRW5V5SuGs)
* **Popout liveviews**: Click the button in a liveview to pop it out into a separate window. If you have multiple monitors, you can drag it to a second monitor. When you move between wizard steps, or review/compare states, the separate windows will be shown/hidden automatically. Close the popped-out window to dock it back in the main Velogic Studio window.

  ![](/files/otWKdvSMzIT72uZ5XzPK)

  To pop out a liveview, click the icon on the top-right:

  ![](/files/QBVUMk33vNqUJ8FVlFSZ)
* **Popout comparisons**: Just like the liveviews, you can pop a window out from the comparison panel. If you resize the popped-out window to be vertically oriented (taller than wide), they will "stack" vertically rather than horizontally.

  ![](/files/JsOYoOcEt1DVhFnoLhXY)
* **Stroke-mode for frontal and webcam videos**: Previously, stroke-mode was only available for lateral cameras. Now, Velogic Studio will use the crank angle data from the lateral cameras to create stroke-mode analyses for webcams and the frontal (Aero) camera. Please ensure your Orbbec cameras are updated to the latest firmware (v1.5) by expanding the "About" section on your camera's configuration panel on Step 1, and clicking the "Update" button if you're not already on v1.5.

  ![](/files/xAfh8CpajJilsLhl9s5q)
* **Position name in Motion Metriqs**: The Motion Metriqs panel now shows the name of the currently locked-for-review fit log entry.
* **Position comparison in Motion Metriqs**: When comparing two positions, the Motion Metriqs panel now shows a selector to switch between Position 1, Position 2, or Delta (the difference between them).

  ![](/files/L5oBoT7BTiiOcZuC4Zr4)

### Improvements

* **Comparison mode headers**: Improved layout of left/right column headings when comparing positions.

### Bug Fixes

* **Calibration recovery after crash**: Fixed an issue where calibration settings would not be properly restored after an unexpected application restart.
* Many other bug fixes, performance and stability enhancements.

This release is foundational, providing capabilities required by the upcoming gebioMized saddle pressure mat integration.

# The bike fit process

A comprehensive guide to the three-step bike fitting process in Velogic Studio

## Step 1: Configuration and rider details

After starting Velogic Studio (and optionally signing in, if you haven't signed in recently), you'll see Step 1:

![Step 1 configuration interface showing rider details and camera setup options](/files/Zur3uSGOxiNRwvmxF2EW)

Step 1 is for you to get all setup prior to the fit session commencing. The client name, email and bike brand/model are used on the report at the end of the fit process.

### Rider details

On the right-hand side you can set details of your client:

* Name, email, bike brand/model: these are included on the report
* Fitter: you can set up a list of different people who conduct fits in your studio (click Settings button to set these up). Pick one from the drop-down to include it on the report.
* Position for fit - choose Road, Tri or Mtb. Your choice here will dictate the position of measurement points, and which body metrics are displayed for the rider.

The "Reopen Session" button allows you find and open a previously-saved session.

### Configuration

The left-hand side of step 1 is all about configuring the sources of fit data. This might be your Kinect or Orbbec camera(s), but you can also specify webcams, ANT dongles/devices, and more.

Scroll down to make sure that your input sources are configured correctly, then click "Next" to go to the capture screen.

## Step 2: Capturing data

Step 2 is where most of the action happens during a fit.

![Step 2 capture interface with liveview, Motion Metriqs, and fit log sections](/files/T05Xx9sFT2RAy2ViPPc6)

### Liveview section

The Liveview section shows the video input from connected cameras. When you have a capture locked for review, these will change to show the captured video.

### MOTION METRIQs section

This displays numeric information from your fit sources. Most metrics come from the Kinect or Orbbec camera, but you'll also see data from any ANT+ devices you've got connected, and a system-calculated cadence metric.

If you would like to customise what's displayed in this area, see: [Customising display of MOTION METRIQs](/section-02-using-velogic-studio/customising-motion-metriqs)

### Fit log section

The "strip" along the bottom of the screen is the fit log. It shows all of the captures you've taken, and there are many ways that you can interact with it. See [Reviewing fit artifacts](/section-02-using-velogic-studio/reviewing-fit-artifacts) for more detail.

On the right of the fit log is the Capture section.

### Capture section

When you want to evaluate the current position of your rider, make sure the rider is pedaling at a realistic cadence and click the "Start capture" button. You'll see a short countdown, and then the system will capture data for a 15-second period.

During the capture period, the system will start displaying data while it continues capturing. You can enter notes in the textbox during the capture (or before or afterwards) to help remember why you captured this position.

When the capture period has finished, you can save or discard the capture. If you save the capture, it will be added to the Fit Log section at the bottom.

The "Measure bike" button takes you through a process using the measurement wand to capture the location in space of specific points on the bike, and calculate measurements from those. See [Taking bike measurements](/section-03-calibration-and-measurement/taking-bike-measurements) for more about this.

Once you've completed the fit, taking as many captures as required, click Next to progress from the capture screen to the report screen.

## Step 3: Report

![Step 3 report interface showing preview and customization options for fit report](/files/lwASjkZdEhKWzsKxGmjE)

The report page prepares and previews a full fit report, incorporating:

* the images and metrics from your initial & final captures
* bike measurements, either entered manually or taken automatically with the measurement wand
* your commentary, either entered directly into a textbox on this Step 3 or into a Microsoft Word document.

For a full explanation of the options in this step, see: [Report options and pages](/section-02-using-velogic-studio/report-options).


# Joint marker placement

Complete guide to placing joint markers for accurate motion tracking in Velogic Studio

This is best performed with the rider on the bike. Before beginning to place the markers:

* Explain to customer that you will be placing markers on their joints so some physical contact will be required (this should also be explained in pre-fit material).
* If the rider is wearing a loose shirt you may need to ask them to tuck it into shorts to avoid obscuring the hip marker
* Watches will often need to be removed also
* Communicate throughout the process and avoid unnecessary contact
* The marker locations are generally intended to be on the bones at the centre of joint rotation.

There are 8 marker locations:

* Toe
* Heel (optional)
* Ankle
* Knee
* Hip
* Shoulder
* Elbow
* Wrist

The same joints are marked for each of the position styles the system supports (Road, MTB and Triathlon) although the placement on hands and elbow may differ.

## Marker Tape

Velogicfit marker tape is supplied in rolls of 100. The markers utilize night vision technology based reflective powder printed on to standard kinesiology tape. The tape can be cut with any pair of sharp scissors, we supply a set of scissors that are designed specifically for cutting kinesiology tape to avoid sticky residue but it is not compulsory to use these. The marker tape is not reusable. It is worth noting that the software uses both the reflective marker and some area of the surrounding tape for the analysis so it is not recommended to cut the tape down to only the diameter of the marker. It is sufficient to leave the tape as a rough square. Note that newer tape is blue and is pre-cut into squares, making the application process faster.

![Velogic marker tape showing reflective markers on blue kinesiology tape squares](/files/3eQNUcWbEV3f7H3TKWx8)

It is theoretically possible to use any 25mm diameter retro reflective marker. We tested extensively during the development of the software and could not find anything that performed as well as our prototype tape, which is why we recommend the tape instead of a generic alternative.

## Toe: 5th Metatarsal Head

Palpate the outer side of the riders foot (just above the pedal axle is a good place to start) to find the most prominent bony protrusion. Place the marker here, slightly oriented to the upper side of the shoe so it is not pointing down.

![Side view of foot showing placement of toe marker on 5th metatarsal head above pedal axle](/files/Rqu6yhFOIX1Yrzj1UaKu)

![Close-up view of toe marker placement on outer side of cycling shoe](/files/lifvT5sS0QHR98PNk11T)

## Heel

The heel marker is optional; if you include it, you need to set the dropdown in the camera settings to Eight.

![Camera settings dropdown menu showing Eight marker configuration option](/files/f97juVsYQTcf9gHTkouH)

We recommend that you do include this marker, because it allows the calculation of more accurate ankle flexion metrics.

The placement of this marker should be:

* Towards the back of the shoe, but not so far around the heel that the camera can't see it
* At the same height above the sole as the toe marker
* There should be some "margin" (visible tape around the reflective dot), especially below the dot. Don't put it right on the edge of the bottom of the shoe.

![Heel marker placement on back of cycling shoe at same height as toe marker](/files/4kMoRYhz8jxwbnb3fYEy)

## Ankle: Lateral Maleolus

Place a thumb and finger either side of the bony protrusion of the ankle. Centre the marker between your digits. If the rider is wearing ankle socks you may need to pull them higher, or try to push them down. Whatever is required to give the marker good contact in the correct position.

![Hand positioning to locate lateral malleolus bone for ankle marker placement](/files/PuNBNFdkVmSx3gVhCbNQ)

![Ankle marker placed on lateral malleolus with proper positioning technique](/files/sUN0lnSEfkcxdyfYnref)

## Knee: Distal Femoral Lateral Epicondyle

Ask the rider to set the cranks in the horizontal position, with the near foot forward.

Palpate just below and behind the Patella (kneecap) to find the gap between Femur and Tibia. Then palpate from the back of the knee to find the rear of that junction.

Place the marker centred on the bone between your finger and thumb.

![Knee marker placement technique showing palpation of femoral lateral epicondyle](/files/tQO9AfkZ4pT5KP0ONfDZ)

![Knee marker properly positioned on distal femoral lateral epicondyle](/files/DBwxGuPuFIDLLodY4Tka)

## Hip: Greater Trochanter

With the riders leg in extended position palpate to identify femoral head. If it is not clear where the bone is (common for all but the leanest riders) you may find that asking them to pedal backwards slowly causes the bone to pop out more clearly. A useful technique for finding a starting point can be to ask the rider to sit up off the bars and place their hand on the side of their hip. With the heel of the hand at the top of their pelvis - the middle finger should extend to just over the greater trochanter.

![Hip marker placement technique showing location of greater trochanter](/files/KRlmTckuw1n4DAZEjoTq)

![Hip marker positioned on greater trochanter with rider in extended leg position](/files/YRvX0m2LPDIMO3QE4i23)

(Note: some types of lycra are particularly difficult to stick to. If you are having issues it can be worth using Kinesio tape to provide a larger base for the marker. Also, riders will often wave their hands past their hips when off the bike - it can be worth asking the rider to hold their hand on this marker when they sit down off the bike so they are aware of the risk)

## Shoulder: Greater Tuberosity of the Humeral head

(Not on the Acromion Process as in other systems.)

With the rider sitting on the hoods locate the acromion process (end of clavicle) then move down roughly 3cm (1 inch) to find the head of the Humerus When choosing the location, be sure to orient the marker such that it faces the Kinect as much as possible.

![Shoulder marker placement on greater tuberosity of humeral head, 3cm below acromion process](/files/bQmGiM54SgrQCS4jene7)

![Shoulder marker properly positioned and oriented toward Kinect camera](/files/niC0Zo4uvVe7Ei1ZUKbu)

## Elbow: Lateral Epicondyle

For Road and Mountain: Palpate the riders elbow to find the end point of the Humerus. You may need to carefully choose where to place the marker to avoid having it folded over by the indent in the elbow.

For a triathlon position the elbow will be more bent, requiring the marker to be placed a little further up the Humerus. If the rider has particularly tall armrests you may need to position the marker a little higher.

![Elbow marker placement on lateral epicondyle for road and mountain bike positions](/files/Ix4aC0yZNdNvpO9JPnrL)

![Elbow marker positioned higher on humerus for triathlon position with bent elbow](/files/ZPanO9ikKLyY7SpfX6oE)

## Wrist: Centre of the Distal Radioulnar joint

For Road Place the dot in the centre of the bones at the top of the wrist. if the rider tends to twist their wrists you may need to place the marker slightly off centre to orient towards the Kinect. Or place the Kinect further towards the front of the bike MTB – the marker will need on be on the head of the Ulna – to the outside of the wrist so it is facing the camera For Triathlon you will also need to look out for the rider twisting their wrists, in general the centre of wrist location is the standard

# Troubleshooting marker detection

Comprehensive guide to troubleshooting common marker detection issues in Velogic Studio

Velogic Studio should be giving you a solid wireframe/skeleton:

{% embed url="<https://ik.imagekit.io/vfframes/docs/George%20skeleton_D-74O6nry.mp4>" %}

and the Quality Indicators should be showing "Good" for detection:

![Quality indicators showing Good detection status for proper marker recognition](/files/mGTLZU1q4OBxAXCPMLQj)

If you're not getting that, this page will help you troubleshoot.

## Look for red dots - any extra? Any missing?

If Velogic Studio can't find a valid skeleton from 7 (or 8) dots, it will instead show you red dots for the markers it did find.

![Red dots displayed when Velogic Studio cannot form valid skeleton from detected markers](/files/StDUu3H9QOjzNVms0WxU)

You can watch as the rider pedals and see if one of the markers is occasionally not being shown as a red dot. If you notice that, adjust the problematic marker so that the camera can see it better.

If you see additional red dots in the scene (like reflections on the front wheel rim), you may need to obscure it e.g. by covering with masking tape. Note that Velogic Studio can cope with some additional reflections, particularly if they're nowhere near a valid marker position; but if there are many additional reflections, or they are near a valid marker position, you will need to cover it up.

## Check marker placement

Refer to our [marker placement documentation](/section-02-using-velogic-studio/joint-marker-placement). The markers need to be placed where the camera can see them directly. Common issues are:

* Shoulder marker placed too high
* Wrist marker rotated too far away from camera
* Heel marker (if used) too far down on the shoe

## Check correct number of dots selected (7 or 8)

There's a configuration setting on Step 1 which tells Velogic Studio whether you're using 7 markers, or 8 (including a heel marker). Make sure that the setting matches the actual number of markers you're using.

## Look for other reflections highlighted as red dots

* Logos or tabs on shorts, jersey and shoes
* Shiny parts on the bike
* Alloy rims

We have a lot of filtering in the detection process to eliminate the extra reflections and the high grade markers (the material printed on the VF-Tape is night-vision rated) are part of how we distinguish between wanted and unwanted reflections.

## Unusually large/small/unusually-proportioned rider?

To help Velogic Studio filter out unwanted reflections, it has some internal rules to make sure that the skeleton formed by the markers could reasonably form a human body. Some of the rules are around proportionality, and some involve sizes of body segments.

Sometimes you may encounter a situation where a rider breaks one of our proportionality rules (more likely with very short or very tall riders). If you are seeing 7 (or 8) red dots, all in the correct place, but Velogic Studio is not producing a wireframe/skeleton, this may be the case for you.

To help us refine the rules, please submit a sample file which we will then investigate and use to tune the rules. See "Submitting a file for us to access" below.

## Camera too far away?

If the camera is positioned more than around 8' from the plane of the bike, the dots may be too small for the camera to recognize.

# Knee track

Understanding and interpreting knee track visualization in Velogic Studio for better bike fitting

As a fitter, it's useful to know what your rider's knee is doing during the pedal stroke. For example, is the knee moving directly up & down, or is it flaring out (away from the frame) at the top of the stroke, possibly indicating hip impingement? Is the "up" stroke different from the "down" stroke, possibly indicating pelvic twisting?

Some bike fit systems attempt to visualise this with a frontal camera and lasers; and you can certainly use a frontal webcam and laser with Velogic Studio.

However, Velogic Studio has an even better way to visualize and quantify knee movement, made possible because our lateral camera can see depth. This means that Velogic Studio can see the knee moving away from the camera & towards the frame (and vice-versa) during the stroke.

## Knee track visualization

![Knee track visualization showing green and blue lines representing downward and upward knee movement paths](/files/x4feao9oWM8P7mYG8cWI)

The knee track is collected automatically when you [capture a position](/section-02-using-velogic-studio/bike-fit-process#step-2-capturing-data). The components of the knee track visualization are:

* An illustration of of a rider. This will appear on either the right-hand side or left-hand side of the image, depending on whether the capture was of the right side of the rider or the left.
* Green and blue lines representing the path of the knee as it travels down and up the pedal stroke.

This single image captures the path of the knee all the way through the pedal stroke. It may help to imagine a small light mounted on the side of the rider's knee, and a long-exposure camera. You can imagine the light being green when the rider's knee is moving down, and blue when the rider's knee is moving back up. If you could capture the path of that light, averaged over many pedal strokes, you will have a good mental image of what the knee track image is showing.

## Interpreting the knee track visualization

Velogic Studio provides you with a lot of data so that you can make judgements across a range of factors. You shouldn't try to diagnose issues solely from the knee track; however, there are some characteristic "patterns" that might help indicate particular problems.

### Angled knee track

This may indicate that the seat is too low, forcing the knee to move outwards when it is flexed.

![Angled knee track pattern indicating potentially low seat height forcing outward knee movement](/files/HATSXa1VM2IxGO5V9rSI)

### Separated knee track

If the down stroke and up stroke are very separated, with the down stroke is much closer to the frame, this may indicate that the rider is twisting their pelvis e.g. to accommodate the seat being too high.

![Separated knee track showing distinct downstroke and upstroke paths indicating possible pelvic twisting](/files/lOoJ10unv1LhYVzmIpVH)

### Mostly vertical & close together

A knee track where the lines are mostly close together and close to vertical generally indicates good stability on the bike.

![Vertical knee track with close-together lines indicating good stability and proper bike positioning](/files/vsGyziOBTQkCJbCIwZ9k)

## Advantages of Velogic Studio's knee track vs webcam + laser

* The information is available as a single image, rather than a video - so it can be included in the report.
* The information is averaged over many pedal strokes, so one odd pedal stroke doesn't give unrepresentative data
* The direction of travel is clearly indicated, by color & arrowheads
* No additional hardware or fitter interaction required; knee track is collected as a byproduct of a normal capture
* You can more easily compare changes in knee track, using overlay and morph comparisons (see [Reviewing fit artifacts](/section-02-using-velogic-studio/reviewing-fit-artifacts))


# Troubleshooting Velogic Studio

Comprehensive troubleshooting guide for common Velogic Studio issues including performance, crashes, and video problems

If you can't get any information at all from the Kinect, or the Kinect is disconnecting: check out our [hardware compatibility guide](/section-01-getting-started/pc-system-requirements) and [Kinect camera troubleshooting guide](/section-01-getting-started/kinect-troubleshooting) first.

Once you're sure that the Kinect is working fine (i.e. the Kinect Configuration Verifier is stable and giving 29-30 FPS), this guide will help you troubleshoot application issues.

## Wireframe does not appear automatically

See: [Troubleshooting marker detection](/section-02-using-velogic-studio/troubleshooting-marker-detection)

## Framerate is low

If you are trying to achieve the best environmental conditions (to improve the framerate) there are some things to check for.

* If this is the first time you have run Velogic Studio, or you have just upgraded to a new version - Windows may still be busy optimising the application for your computer. Please leave it to run for a few minutes and then close and restart.
* Strong light sources (window, door, light bulb) behind the rider, in view of the Kinect will lead to worsened frame rate and a blurry image (though this does not affect the measurement - just the colour image).
* Poor lighting conditions can mean a dimly lit area, or only overhead. Any lighting situation that creates a gradient across the rider (ex. bright at the top and dark at the bottom) or hot spots (shining directly at one of the markers) will harm the lighting score.

See also: [Lighting & environment](/section-01-getting-started/lighting-environment)

## Liveview isn't live (freezes after one frame)

This is a known problem with Intel Iris Xe graphics drivers. There are a few different solutions:

* You can update your drivers to the latest version and see if the problem is fixed. You should be able to do this with either Device Manager (expand Display Adaptors, right-click your graphics card and choose Update Driver), OR manually install the [driver version recommended by Intel](https://www.intel.com/content/www/us/en/download/19344/30579/intel-graphics-windows-dch-drivers.html?) to fix this specific issue. If you install that driver version and still get the freeze, try using [Intel's own management software](https://www.intel.com/content/www/us/en/support/detect.html) to update to a later version of graphics drivers.
* You can disable the problematic code for your whole computer by setting this dword flag in Registry Editor: `HKCU\SOFTWARE\Microsoft\Avalon.Graphics\DisableHWAcceleration : 1`
* Velogic Studio has a special setting to disable hardware acceleration to work around this issue: Settings -> Support -> Force software render mode. It's generally better for this setting to be off (because it forces your CPU to do work that should be done by the GPU), but turning it on will work around the driver issue.

## Occasional random crashes

Velogic Studio is a very stable application, but if you experience occasionally crashes, read on for possible solutions.

### Update display drivers

Velogic Studio uses functionality from your video drivers. If the video drivers are buggy, this can cause instability in Velogic Studio.

Follow [this guide from Microsoft](https://support.microsoft.com/en-us/windows/update-drivers-in-windows-10-ec62f46c-ff14-c91d-eead-d7126dc1f7b6), but in Device Manager choose "Display adaptor" instead of the example given in the article: ![Device Manager window showing Display Adapters section for updating video drivers](/files/4L3VRfMkm6odWLCYAGVm)

### Tell antivirus not to check the files saved by Velogic Studio

If Velogic Studio is "freezing up" for you when you save a capture, this might help. Windows has a built-in antivirus which scans every file saved to disk. Sometimes we think it mis-identifies a video being saved as a virus, and will halt Velogic Studio without any error report being sent.

You can avoid these false positives, and also reduce the time taken to save the results of each capture, by telling Windows to ignore the directory where Velogic Studio fit data is saved:

* Click "Start" and type in "Virus", click on "Virus & threat protection"
* Click "Manage settings" on "Virus & threat protection settings"

![Windows Defender Virus & threat protection settings with Manage settings button](/files/AjwkYePrkcySOgWewl2t)

* Click "Add or remove exclusions"

![Virus protection settings page with Add or remove exclusions option](/files/BXqsWWdCIo1MtgV4ar8K)

* Click "Add an exclusion" and then "Folder"

![Add exclusion dialog with Folder option selected for excluding fit data directory](/files/Z7x6DrqU2aHufIB6oXsM)

* Choose the folder where Velogic Studio saves fit data (usually this will be "Documents\Velogic Studio fits", but you may have changed it in Velogic Studio's settings)
* Restart Velogic Studio

### Check for other applications using LibUSB

Some customers have reported issues with Velogic Studio freezing when other applications which use LibUSB are installed on the same computer. One example of such an application is the EBike management software.

You can check for LibUSB by looking in Driver Manager.

![Device Manager showing LibUSB drivers in system devices list](/files/hXb1ocSPuIcsUveUDmiJ)

If you find LibUSB is present on the computer, try removing any other USB dongles from the computer. If Velogic Studio is still unstable, try remove libUSB from the computer (right-click on the entry in Device Manager and choose "Uninstall Device")

### Check for Velogic Studio error messages in the Event Viewer

Visual Studio writes error information into the Windows Event Log. We might ask you to check the logs and send us a file with relevant information. Here's how you do that:

* Press Windows key and search for "Event Viewer", then click to run it

![Windows Start menu search results showing Event Viewer application](/files/2QS0fb378bpDYky6hIzH)

* Click "Windows Logs" and then "Application"

![Event Viewer with Windows Logs and Application section highlighted](/files/ka0UlJoYkQnfa3Brdu7w)

* In the Actions area on the right-hand side of the window, click "Filter current log"

![Event Viewer Actions panel with Filter current log option selected](/files/S93cvKraA6BemZBtEMAe)

* In the Filter popup window, set the options: Event level = Error, Event sources = .NET Runtime, Event ID = 1011, then click OK

![Filter Current Log dialog with Error level and .NET Runtime settings configured](/files/xxVshALEL97aByr8XfVs)

* In the Actions area on the right-hand side of the window, click "Save Filtered Log File as..."

![Event Viewer Actions panel showing Save Filtered Log File option](/files/MMAM7l6jpOewJPdGVQqD)

* In the Save dialog, give the file a name (e.g your name) and save it somewhere you can find it again, e.g. the desktop

![Save As dialog for exporting filtered event log file to desktop](/files/qkeOYw7WwJPfAyIdUjzr)

* Send an email with that file attached, to <support@velogicfit.com>

### Upload dump files

If Velogic Studio exits unexpectedly (crashes), it should write a dump file to a directory on your computer and then restart.

When it restarts, it will notice that the dump file exists, and show a prompt at the bottom of the main Velogic Studio window.

![Velogic Studio crash dump upload prompt with Upload button at bottom of window](/files/KIExcrb85oClDMksqq5x)

These dump files are very useful to help us diagnose, and eventually fix, the issue that caused the crash. If you see this message, and you have reasonable internet connection, please click "Upload" button. Velogic Studio will zip the dump file(s) and upload them to our support team.

It may take several minutes to upload, but you can use the application as normal while the upload is happening, and you can cancel it at any time.

If you don't wish to upload the files to support, you can click "Delete". Or you can click the X button to hide the message without taking any action.

### Sending us a manual dump file

If Visual Studio becomes unresponsive, but it doesn't automatically create a dump file (see above), we might ask you to manually create a dump file. Here's how to do that:

* Run Task Explorer (by pressing ctrl+shift+esc keys all together)
* Find Velogic Studio, and click the expander next to it

![Task Manager showing Velogic Studio process with expanded view of sub-processes](/files/xDC2bY3Xzu5qPBkfOg4l)

* Right-click on the process and choose "Create dump file"

![Right-click context menu on process showing Create dump file option](/files/1L1ndaIPcVyVaHYNMk2m)

* You'll see a message like this:

  ![Dump file creation progress dialog showing file generation in progress](/files/GnNi3kgxzEl1FWHPjnCn)

  ... and then after a few seconds, you'll see:

  ![Dump file creation completed dialog showing file path location](/files/kvJkZGcH5nyhIJBS0tKd)
* In your web browser, visit <https://vlgc.io/upload>, and click the "Select files" button

![Web upload interface at vlgc.io/upload with Select files button](/files/kYIxvye4yh6G6tLoImi4)

* Navigate to the path from the previous step (e.g. c:\Users\<yourname>\AppData\Local\temp\Velogic.Studio.App.DMP). To make that easier, you can type this into the File name box: `%localappdata%\temp\Velogic.Studio.App.DMP`
* Enter your first & last name, and click "Upload"

![File upload form with name fields and Upload button for sending dump file](/files/BbBkWnZWv4tuvHwyZar7)

* It will take a few minutes to upload, depending on your internet connection. The dump file is likely to be around 1GB, so if you are on expensive internet, please contact us to make sure this is the best process for you.
* Please also send an email to <support@velogicfit.com>, explaining why you sent the .dmp file. Ideally your email will contain:
  * What you were doing
  * What you expected to happen
  * What actually happened

## Application generally feels sluggish, videos are laggy

Velogic applications should always feel "snappy" and have good performance on reasonable hardware. If you have hardware that exceeds our minimum specs, and you're not getting the performance you're expecting, here are some things you can check.

### Try unplugging webcam

We have had reports from users that some webcams take a lot of CPU themselves, leaving not enough for Velogic apps to do their work. Try disconnecting your webcam, and if the performance is noticeably better, use a different webcam.

### Use Process Explorer to find the bottleneck

Process Explorer is a free utility from Microsoft (part of the free Sysinternals toolset).

You can download or run directly from the [Process Explorer webpage](https://docs.microsoft.com/en-us/sysinternals/downloads/process-explorer). Simply find the Velogic process in the process list, then right-click and choose "Properties". Leave that running while you perform some activities in Velogic Studio, then examine the graphs.

![Process Explorer performance graphs showing CPU usage, memory, and I/O statistics](/files/sYdf7SQtuKkNWMSiSw7A)

You can look at:

* CPU usage - CPU usage is low, which is good. (High CPU usage is not necessarily bad, unless you're unhappy with the overall performance of the application)
* "Private Bytes" - this is memory usage, and should remain fairly constant as somewhere around 500-700MB. If it is continually and rapidly climbing, you may be experiencing a memory leak - please contact us and send a copy of your graph (you can screenshot it with \[Shift]-\[Windows]-\[s] key combo)
* I/O - the IO peaks during the Capture period, when the app is writing video to disk. IO is low aside from that. The CPU peak over the Capture period is quite small, so the CPU isn't working too hard encoding the videos.

We are happy to help diagnose any performance issues that you're having with our software. Please get in touch with as much information as you have - ideally including a screenshot from Process Explorer.

### Submit performance data for us to analyse

We built a tool into Velogic Studio that you can use to submit detailed performance data. See [this article](/section-01-getting-started/submitting-performance-data) for details.

### Sending us system information

Windows has a built-in tool to gather detailed information about your system's hardware and operating system. This can sometimes be useful to help us diagnose issues. If we ask you for this:

* Click Windows menu and type "System Information", then run the app:

  ![Windows Start menu search showing System Information application](/files/JUPEwWRqI1HVEUSrjczP)
*
* Click File -> Export, save the file somewhere (e.g. your desktop) and then email the file to us - <support@velogicfit.com>


# Reviewing and comparing fit artifacts

Complete guide to reviewing, analyzing, and comparing fit artifacts in Velogic Studio including videos, metrics, and stroke analysis

As you carry out the fit, Velogic Studio records various "artifacts" for each capture. These include:

* **Raw videos** from the depth camera(s) and/or any webcams you have at different positions around the rider.
* **Stroke analysis videos** from the depth camera(s), giving a higher virtual-frame-rate and the ability to scrub to particular crank angles
* **Metrics** calculated from the sensor data, e.g. body angles and movement from the Kinect camera, or ANT+ data from sensors on the rider or bike.

Velogic Studio makes it quick & easy to review and compare these artifacts, so that you can clarify the effect of changes in position - both for yourself, and to show your client what you're seeing & why you're making changes.

## Hovering over thumbnails in the Fit Log

The quickest way to review a previous capture is simply to move your mouse over the thumbnail images in the Fit Log at the bottom of Step 2:

![Fit Log thumbnails at bottom of Step 2 showing capture previews with mouse hover functionality](/files/rVH0J2RGNhzOhdNSVtYW)

When you move the mouse over a thumbnail image for a particular capture, Velogic Studio will auto-play see the videos saved as part of that capture. The Motion Metriqs from that capture will be displayed on the right-hand side, and the title of that area will change from "Motion Metriqs" to the number and comment from that capture.

Because this is triggered by just a mouse move, if you move the mouse away, Velogic Studio will return to live mode.

## Locking a capture for review

If you want to interact with the artifacts from a particular capture, just move the mouse over that capture's thumbnail (as above) and then click the "LOCK" button.

The appearance of that capture's thumbnail will change to show that it's now locked:

![Locked capture thumbnail with changed appearance indicating review mode is active](/files/P8ziJmyqXiQphVeZGFeL)

...and you can then move the mouse off to interact, e.g. to scrub the videos or change into Stroke Analysis mode, or to click on a metric (see below).

## Global playhead

When you're reviewing a capture (either by hovering over the thumbnail, or locking it for review) a global playhead will appear at the top of Step 2. You can use this to control all videos from a single place, and also to control things like the analysis mode (raw vs stroke) and the playback speed.&#x20;

### Stroke analysis mode

The default playback mode is Raw, which is just the realtime video recorded during the capture. But you can click the Stroke button in the global playhead to go into Stroke analysis mode. In that mode, the raw video will be replaced by Stroke Analysis video:

![Stroke Analysis mode showing crank angle scrubber with 0°, 90°, 180°, 270°, 360° markers](/files/ThclYKVN3axLA5n1jmLK)

Stroke Analysis is a detailed way to review a capture. There is still a scrubber bar at the top (just like for raw video), but there are some big differences. The horizontal axis of the Stroke Analysis scrubber does not represent time; instead, it represents crank angle. You can see labels for 0° (top of pedal stroke), 90° (\~middle of power phase), 180° (bottom of stroke), 270° (\~middle of recovery phase) and 360° (back to the top of the pedal stroke).

The small dots which appear along the horizontal axis each represent an individual frame, captured at that crank angle. Velogic Studio has automatically analysed all frames from the capture and re-ordered them to create a virtual-high-frame-rate video.

Note that because the frames have been reordered, if the rider was moving their head during the capture, their head will appear to "flicker" in the Stroke Analysis mode. You might want to ask your rider to fixate on a point and try to keep their head still during the capture to minimise this effect.

When you grab the scrubber and drag left/right, other videos from that same capture (e.g. if it was a bilateral capture) will move to the same crank angle.

### Drawing tools and grid

Sometimes you want to draw on-screen to explain something to your client. If you click on the "DRAW" button at the top of the video, you'll see a drawing toolbar appear overlaid on the video:

![Drawing toolbar overlay on video with annotation tools for client explanations](/files/x8srJkaJ69ZgIkEQy2dE)

You can click on the border of the drawing toolbar to move it around within the video area. The tools on the toolbar are probably already familiar to you if you've used other drawing systems in the past, but here's a summary from left to right:

* The "selection" icon lets you draw a rectangle around drawings you've already made, so that you can move or delete them by clicking the Delete key on the keyboard
* The "angle" tool lets you draw an angle with 3 mouse clicks, and will show the degrees inside that angle (or the external angle if you hold the CTRL key). Note that the angle measured with these tools is a simple 2D measurement; if you were to try to use this tool to measure an angle reported as a MotionMetriq (e.g. knee angle), they are likely to be different - because MotionMetriq's are measured (more accurately) in 3D, using information from the depth camera.
* The "line" tool lets you draw a simple 1-segment line
* The "multiline" tool lets you draw a line made of multiple segments. You can double-click or press Enter to finish drawing.
* The "pencil" tool lets you draw completely freehand
* The "text" tool lets you draw textual annotation
* The "save" icon will save a snapshot of the drawing (and the current frame from the video) into the fit folder. It will ask for a name for the snapshot, and will save the snapshot into the fit folder. If you have the "Include annotated images" option turned on when you later generate the report, the snapshot will automatically be included in the report, along with the name you gave it.
* The "delete" icon will delete all drawing items.
* The "close" icon on the right will hide the drawing toolbar. The drawing items will remain on the screen; to remove them, you need you click the "delete" icon on the toolbar.

Clicking on the "GRID" button will overlay a "laser grid", so you can watch the movement against known-vertical and known-horizontal lines (in 2D):

![Laser grid overlay on video showing vertical and horizontal reference lines](/files/4jne7jBrwJTXtKYjBsEv)

## Focusing on one particular metric

You can click on any metric in the MotionMetriqs area:

![MotionMetriqs panel with clickable metrics for detailed analysis](/files/ek0BPV23jpV8FGl4DKxc)

...and it will be highlighted with a "lock" symbol, and a number of things will happen:

* the fit log thumbnails (along the bottom of the screen) will have the value for that metric overlaid, so you can quickly see how it has changed between captures:

  ![Fit log thumbnails showing metric values overlaid for quick comparison between captures](/files/MPhBZwlWrCwAQHzGXE60)
* the visuals will automatically skip to the frame which best illustrates that metric (if appropriate)
* a visualization will be drawn on the frame, to illustrate the metric to you and your customer:

![Video frame with metric visualization highlighting specific body measurement](/files/ZjqxgdB6NOJh4GIXaZjC)

There are many different visualizations available, here are some examples:

![Joint angle visualization showing biomechanical angle measurement on rider](/files/0AVkulTHdk3atq4iyDMT)

![Lateral movement visualization displaying side-to-side motion tracking](/files/aXLXD4hvkpL2Rxw2HndS)

![Horizontal and vertical movement visualization showing directional motion analysis](/files/FrmTO9n4d4i6Ov17lbjy)

![Ankle swivel visualization demonstrating rotational movement measurement](/files/lKcHxamwDQS2KAOsaol5)

See also:

* [Ankle flexion metrics](/section-02-using-velogic-studio/ankle-flexion-metrics)
* ![Cadence metric display showing pedal rotation rate measurement](/files/olzfgC19LCWqvP0bsdjQ)

To stop focusing on that metric, just click it again in the MotionMetriqs panel to deselect it.

## Comparing 2 different captures

If you already have one capture locked for review (see above), when you mouse-over a different capture you'll see a "Compare" button at the top:

![Compare button interface for analyzing differences between two captures](/files/kgeHVa5xrTf71oU3l2tz)

If you click that "Compare" button, the layout of the visuals area will change to put the equivalent visuals from those 2 captures side-by-side, and you can scroll down to interact with each pair:

![Side-by-side comparison view of two different captures with synchronized playback](/files/UwX8W505naP4kV84gbkk)

Initially, the visuals will play in "raw" mode: just the actual video recorded during the capture period. But, if you click on the "Stroke" button at the top, or click on any of the MotionMetriqs, the videos will go into Stroke Analysis mode:

![Stroke Analysis comparison mode with crank angle synchronized between two captures](/files/yRG8RVljhUUeF1Fc0UJv)

... and because Stroke Analysis mode is based on crank angle, you can drag the scrubber bar at the top to move both sides with the crank angles synchronized.

In Stroke Analysis mode, there are also additional comparison modes available:

* Side-by-side (the default)
* Overlaid (image)

![Overlaid comparison mode showing two positions superimposed for direct visual comparison](/files/z3fZVQdZo9KWIJaM2hSO)

* Crossfade (video)

{% embed url="<https://ik.imagekit.io/vfframes/docs/Crossfade%20comparison%20of%20IP_172.16.0.2%20from%20position%203%20to%205_27VtK6qZg.mp4?updatedAt=1705968624701>" %}

* Morph

{% embed url="<https://ik.imagekit.io/vfframes/docs/Morph%20comparison%20of%20IP_172.16.0.2%20from%20position%203%20to%205__2pbFHSs_.mp4?updatedAt=1705968624596>" %}

The Crossfade and Morph visualizations both generate videos on-the-fly, for the crank angle you have selected. You can click "Save" to save the video as an .mp4 in the fit folder.

## Checking and clearing lock or focus/compare state

When you've got a capture locked for review, and/or a second capture locked for comparison, and/or you're focusing on a body metric, the capture area will change:

![](/files/AsQ66SP95GlY1EES4qw6)

This is helpful if you're confused about what state you're in, and also makes it easy to return to the default state. You can click the X button next to any of the indicators, or click the CLEAR ALL button to return to the default mode.

## Reviewing with the Fit Log Grid

When you really want to drill into the changes between captured positions, you can pull up the Fit Log Grid by clicking on the button to the left of the fit log thumbnails, at the bottom of Step 2:

![Fit Log Grid button located left of thumbnails for detailed data view](/files/UbHqr8fqsRzSmSmbhxpy)

This will pull up the Fit Log Grid, so that the thumbnails (which were at the bottom of the screen) are now at the top of the screen, with all the data for each position shown underneath in a grid format:

![Fit Log Grid view showing thumbnails at top with detailed metrics data below in table format](/files/hJS9odIjuObhhOnCQicL)

Numeric data (such as metrics) are shown with an indicator showing the change from the initial position.


# Spark Lines in the Fit Log

How to use spark lines to visualize changes in MotionMetriqs over the course of a fit

Sometimes it's useful to get a graphical indication of how a particular MotionMetriq has changed over the course of a fit, such as after you've completed a [sustainability test](/section-04-aero/sustainability-test).

Velogic Studio makes that easy through the use of a feature called "Spark Lines". To see a spark line, just click "SHOW GRID" to open the fit log grid, and then click on one or more body metrics.

You will see a series of lines displayed overtop of the fit log grid:

![Fit log grid displaying spark lines visualization with colored trend lines for selected metrics](/files/2jqxFJrU0zh0q8b0X8zi)

If a metric has left/right values, you will see a solid line for the left metric and a dotted line for the right.

You can click on multiple metrics and the lines will be automatically assigned different colors.

Simply click on the same metric again to turn the spark line off for that metric.


# Ankle Flexion metrics and visualization

Learn about ankle angle and flexion metrics in Velogic Studio, including the new 8th marker capabilities and advanced ankling visualization

## Historical: Ankle Angle metrics

Historically, Velogic Studio used 7 markers: wrist, elbow, shoulder, hip, knee, ankle, and toe. From those 7 markers, a range of metrics were calculated; for the foot, this was mainly "Ankle Angle" which is a simple measure:

![Ankle angle measurement diagram showing simple angle calculation between ankle, toe markers and vertical reference](/files/l8Dg107Dy3P01O31UFTo)

From this measure, across a capture period, Velogic Studio calculated 2 metrics:

![Historical ankle angle metrics showing average and range measurements in Motion Metriqs panel](/files/o42HYkHWt4c5tdfWc9ei)

1. **Ankle Angle Avg** is the average ankle angle across the whole pedal stroke
2. **Ankle Angle Rng** is the range of ankle angles (Max - Min)

These are good, simple metrics, and can be used to see how ankle movement changes during a fit. However, these metrics suffer from one major problem: the angle calculated is very dependent on the placement of the toe marker. If placed further forward on the foot, the angle angle will be measured as smaller; further back will give a larger number.

## New in v4: Ankle Flexion metrics

With the release of Velogic Studio v4 in 2024, we added the option of using an 8th marker on the rider's heel. This allows a more detailed analysis of ankling.

![8th marker placement on rider's heel for enhanced ankle flexion analysis capabilities](/files/FwZianIYkI9icmxQH5BQ)

If you choose to use the 8th marker, you'll see new ankling metrics in the Motion Metriqs area on the right-hand side of step 2:

![New ankle flexion metrics showing minimum and maximum values with 8th marker data](/files/MSkElMWQyB6cC2XuCCgX)

1. **Ankle Flexion Min** is the lowest observed ankle flexion over the capture period
2. **Ankle Flexion Max** is the highest observed ankle flexion over the capture period

The older "Ankle Angle" metrics are still available too. If you wish to hide those, see [Customising display of MOTION METRIQs](/section-02-using-velogic-studio/customising-motion-metriqs).

## Advanced Ankling Visualization

If you [Lock](/section-02-using-velogic-studio/reviewing-fit-artifacts#locking-a-capture-for-review) in a single capture for review (or [Compare 2 captures](/section-02-using-velogic-studio/reviewing-fit-artifacts#comparing-2-different-captures)), and then click on either the Ankle Flexion Min or Ankle Flexion Max metrics (see above), Velogic Studio will display an advanced visualization of ankling metrics.

![Advanced ankling visualization showing crank angle scrubber with plantarflexion and dorsiflexion indicators](/files/HXvvZ0AJDFXXBeacNbvc)

1. **Crank angle scrubber** is like a normal video playback scrubber (where you can drag the playing head forwards and backwards to "scrub" through the video. The major difference here is that the horizontal axis doesn't represent time in a video; it represents degrees of crank angle in the pedal stroke.
2. **Current crank angle** is shown on the outside of the circle
3. **Ankle flexion** is shown for each frame.
4. Around the outside of the circle, you'll see red and purple areas. These represent the degree of plantarflexion (red) or dorsiflexion (purple) at that part of the pedal stroke.

You can use this visualisation to understand, and explain to your customer, what's going on with the ankle during the pedal stroke.

It's particularly effective when you are comparing either 2 different captures of the same side of the body, or 2 different sides of the body during the same capture:

{% embed url="<https://ik.imagekit.io/vfframes/docs/ankling_bVV5JEwNp.mp4?updatedAt=1705629284451>" %}

You may also like to use this ankle flexion visualization in conjunction with [pedal angular velocity](/section-02-using-velogic-studio/pedal-angular-velocity).


# Pedal angular velocity visualization

Learn how to visualize pedal angular velocity throughout the pedal stroke in Velogic Studio v4

One of the new features in Velogic Studio v4 is the ability to visualize how angular velocity of the pedal varies throughout the pedal stroke.

If you [Lock in a single capture for review](/section-02-using-velogic-studio/reviewing-fit-artifacts#locking-a-capture-for-review) (or [Compare 2 captures](/section-02-using-velogic-studio/reviewing-fit-artifacts#comparing-2-different-captures)), and then click on the Cadence metric:

![Cadence metric in MotionMetriqs panel for accessing pedal angular velocity visualization](/files/hAb8UabtFBzgUjpwk3Y6)

... you'll see a visualization graph overlaid on the Crank Angle scrubber, at the top of the Stroke Analysis video:

![Pedal angular velocity graph showing crank angle analysis with blue line indicating velocity variations](/files/1xagawSL4iWKd0WCn3Ry)

In this visualization:

1. The horizontal axis represents the crank angle
2. The small dots along the horizontal axis represent frames that Velogic Studio has included in the analysis
3. The large dot represents the current crank angle being displayed
4. The blue graph line is Velogic Studio's measurement of the angular velocity of the pedal at that crank angle, arranged above and below the average.

Usually, you would expect to see a peak or "hump" in the pedal angular velocity during the power phase. In the example above, the power phase appears to be "bimodal", which might be something you would investigate during the fit.

You can use this visualization to understand how the pedal/crank is accelerating or decelerating throughout the stroke. It's particularly effective when you compare this between two captures, to understand the effects of an intervention, and may be interesting to investigate correlation with [ankle flexion](/section-02-using-velogic-studio/ankle-flexion-metrics).


# Customising display of MOTION METRIQs

Learn how to customize the MOTION METRIQs panel in Velogic Studio with tabs, groups, and personalized metric displays

## Introduction

The MOTION METRIQs panel, on the right-hand side of Step 2, shows the instantaneous or captured values for all of the metrics calculated by Velogic Studio.

In addition to the default view, Velogic Studio Labs has a powerful customisation capability, so you can be in full control of which metrics you want to see at different stages of the fit.

## How to customise

To start customising, just click the wrench icon at the top right of the MotionMetriqs panel:

![Wrench icon at top right of MotionMetriqs panel for accessing customization options](/files/uBGxfJZBCmV25pNLFkJg)

You will see a new full-screen modal window dedicated to configuration:

![Full-screen configuration modal window showing All Metrics column with customization options](/files/15ehNULZ4oHXOQW6w5fq)

By default, you will see a single column of metrics, called "All Metrics". If you have already used the previous configuration system, these actions will be familiar, you can:

1. Click the pencil icon to rename metrics
2. Click the checkbox icon to show/hide the metric
3. Drag a metric to a different sort order (inside the same group)
4. Drag a group to change its sort order compared to other groups.

When you click done, those customisations will be reflected in the MotionMetriqs area in Step 2 of the application.

### Adding a new tab

The real magic happens when you click the "Add tab" button. You'll see a new, blank column added:

![Configuration window with new blank tab added via Add tab button](/files/6wwevBk2RDhdL5QBFgbM)

Give the tab a name (short is best) and click Done. Now, you can start configuring the new tab:

1. Drag a group from the "All metrics" tab to copy that group into the new tab
2. Or, click "Add group" to create a new group from scratch

Groups on these custom tabs are more powerful that the groups in the "All metrics" tab. You can:

1. Remove items from the custom group by clicking the X icon
2. Drag individual metrics from completely different groups onto a custom group
3. Drag to reorder items within a custom group
4. Drag to reorder groups within a custom tab

![Custom tab configuration showing drag and drop interface for organizing metrics and groups](/files/1BP81f9lq19gtXAXjTTT)

When you have finished customising, just click Done, and you'll now see a tab selector strip at the top of the MotionMetriqs area:

![Tab selector strip at top of MotionMetriqs area showing available custom tabs](/files/cVHCMFsQYnpuEH4C4Psc)

Clicking a different tab changes the MotionMetriqs area to only display the groups and items that you've configured for that tab:

![MotionMetriqs area displaying custom tab view with personalized metric groups](/files/1cFdYABypQmhcLrVba7h)

## Importing and exporting

If you have a configuration that you want to share with someone else, or want to move to another computer, or want to backup, you can do that by Exporting the configuration. Just click on the Export button at the top of the configuration window:

![Export configuration dialog for saving and sharing custom MotionMetriqs layouts](/files/Bjuqo0zS3FJ0pqjwUqYV)

By default, the configuration file will be saved to your desktop, but you can email it or move it to a backup drive or cloud sync folder for safekeeping.

To apply that same configuration to a different computer, just click Import and browse to find the file to import.

## Ways to use this customisation capability

1. You could create a custom tab for "sizing" fits vs post-purchase fits
2. You could create a custom tab for each different stage of your fit process
3. When just starting out, you could create a custom tab with just the basic metrics


# Triathlon metrics

Specialized body angle ranges and fit process guidelines for triathlon and time trial bike positions in Velogic Studio.

While the majority of the metrics are the same for a Tri/TT fit as a road one, there are a few key differences.

![](/files/2H64jmGL3HrjrHGc15hm) *Triathlon position*

The major change in body angles is a much lower torso angle than on a road bike (possible thanks to moving the saddle forward).

## Body Angle Ranges

| Metric         | Range                                        |
| -------------- | -------------------------------------------- |
| Ankle Angle    | Average 100-120, range < 30                  |
| Knee Angle     | Max 140-145, Min >68                         |
| Hip Angle      | Max 85-105, up to 120 if rider has issues    |
| Shoulder Angle | Average 75-100                               |
| Forearm Angle  | Average 0-20 (5-10 is a good starting point) |
| Torso Angle    | 10-15 for Elite, 20-30 general, 30+ rare     |

Joint motion targets are the same as for the road position:

## Joint Motion Targets

| Metric                  | Average Range | Good Range |
| ----------------------- | ------------- | ---------- |
| Knee Lateral Travel     | <40           | <20        |
| Knee Travel Angle       | <8            | 0-2        |
| Hip Vertical Travel     | <40           | <15        |
| Hip Horizontal Travel   | <40           | <10        |
| Ankle Swivel            | <10           | \~5        |
| Shoulder Lateral Travel | <40           | \~20       |

## Tri/TT Specific Metrics

| Metric         | Range (Tri/TT) |
| -------------- | -------------- |
| Knee over foot | 20 to 80       |
| Sitting angle  | 78 to 86       |

Joint alignment is where we really see the impact of shifting the saddle forward. As a starting point aim for a Sitting Angle of 80 degrees and work from there to balance the riders comfort and ability to reach the bars. If they are constrained by UCI rules you will need to trial cut-off saddles in order to hit the correct Sitting Angle. If you are fitting the rider for both Road and Tri/TT bikes. The hip angle and associated metrics should fairly closely match between the road drops and aerobars positions.

## Tri/TT fit process

The process for a Tri/TT fit is (loosely):

1. Set saddle fore/aft such that their Sitting Angle is the correct range
2. Refine Saddle height to minimise Hip/Knee motion and achieve correct knee/ankle angles
3. Set reach to the armpads so that they are near to being under the shoulder and minimising Shoulder Lateral Travel
4. Set reach to the shifters so that the riders elbows are on the pads with the shifters easily accessibly to their hands.
5. Set drop based on hip/knee motion, hip angle and rider feedback
6. Iterate through whichever steps are needed to hit a stable, comfortable position

## Questions to ask the rider

1. Neck pain?
2. Weight on elbows?
3. Pressure on nose of the saddle?
4. Pain on outside of shoulders?

## Other problems to look for

1. Rider is stretching shoulders (dropped Scapula) to reach bars rather than lowering Torso (bars too low)
2. Rider is moving on the saddle a lot (wrong saddle, bars too low or too long)

Note that short crank arms can make a significant difference to the sustainability of an aero position by opening the minimum knee angle and hip angle.


# Road metrics

Reference guide for joint angle, movement quality, and position metrics used in Velogic Studio for road bike fitting.

Our system offers an extensive range of metrics. Using 3D data well requires combining multiple factors in your decision making. Here is some guidance for "orthodox" positions.

## Joint Angle Metrics

| Metric         | Range                                     |
| -------------- | ----------------------------------------- |
| Ankle Angle    | Average 100-130, range < 30               |
| Knee Angle     | Max 140-145, Min >68                      |
| Hip Angle      | Max 90-105, up to 120 if rider has issues |
| Shoulder Angle | Average 75-100                            |
| Elbow Angle    | Average 155-170                           |
| Torso Angle    | 35-40 for Elite, 40-50 general, 50+ rare  |

## Movement Quality Metrics

| Metric                  | Average Range | Good Range |
| ----------------------- | ------------- | ---------- |
| Knee Lateral Travel     | <40           | <20        |
| Knee Travel Angle       | <8            | 0-2        |
| Hip Vertical Travel     | <40           | <15        |
| Hip Horizontal Travel   | <40           | <10        |
| Ankle Swivel            | <10           | \~5        |
| Shoulder Lateral Travel | <40           | \~20       |

## Position Metrics

| Metric         | Range (Road) |
| -------------- | ------------ |
| Knee over foot | 0 to -40     |
| Sitting angle  | 72 to 76     |

> **Note:** Sitting angle is measured with reference to the bottom bracket, which is established during bike measurement. If you haven't yet taken bike measurements, sitting angle will not be shown.


# Report options and pages

Complete guide to customizing and generating professional bike fit reports in Velogic Studio

Velogic Studio has a professionally-designed, full-featured, automatically-generated report. Our users frequently give feedback that this is the "best feature" of Velogic Studio, so let's explore!

The report is generated on Step 3 of the [fit process](/section-02-using-velogic-studio/bike-fit-process). Once you've completed the bike fit, you can use this step to customize the perfect report for your customer.

![Step 3 report generation interface showing customization options and preview](/files/bx6bbYue2vcR4G5Xm1cQ)

## Report options

These options allow you to control what's included in the report.

### Initial pages options

Specify whether the report should include a title page & table of contents.

![Initial pages options for including title page and table of contents](/files/UvZPZnszdVMtZFnCOwbO)

#### Title page

![Professional title page with custom logo and brand colors](/files/2SxPI7gwABzpOePSwfWr)

The title page prominently features your own logo (which can be set, along with your brand accent color, in application settings). The brand color is also used throughout the report.

All pages of the report have a common "identity block" on the right-hand side of the page, with a snapshot image of the customer taken at maximum knee extension.

#### Table of contents

![Table of contents page showing page numbers for quick navigation](/files/GKBjoP6ax9bRrBGpVGcP)

The table of contents simply shows the page number for each page of the report, for quick access.

Note that if you're using the Word fit notes feature (see below), any headings that you use in the fit notes document will also feature in the table of contents.

### Commentary page options

![Commentary page options for summary notes and general notes inclusion](/files/Jh7HYaxVtRqzvfbqCGK7)

The commentary page of the report contains your summary notes from the fit, and optionally "general notes" (which are the same for each fit).

There are 2 ways to record your summary notes:

1. Using the textbox directly below these options. This is useful if you don't take long notes and/or you don't have Microsoft Word on your computer.
2. Using Microsoft Word.

#### Using "Summary from textbox" option

![Commentary page layout with summary text and general notes in two columns](/files/Qi7nhJCImgh5biWmObL9)

If you enter summary text directly into the text box in Velogic Studio, the Commentary page of the report will have two columns: your commentary on the left, and general notes (if selected) on the right.

#### Using "Summary from word" option

If you choose the Microsoft Word option:

* Velogic Studio will automatically create a file called "fit notes.docx" in your fit session folder.
* The "fit notes.docx" file will initially contain whatever was in the summary notes textbox. So, if you've already begun keeping notes directly in the textbox, you can "upgrade" to Word and keep what you've already entered. If you haven't yet entered any specific notes for this fit, it will simply be the boilerplate text from settings.
* Velogic Studio will try to open the "fit notes.docx" file for you in Microsoft Word automatically. You can keep this window open and enter notes directly in Microsoft Word while you conduct your fit.
* If you don't have Microsoft Word installed on your computer, the Wordpad application will be opened. You can use Wordpad to add pictures and formatting to the text; but the experience is not as good as with Microsoft Word.
* Whenever the report is generated, it will automatically scrape the content from the "fit notes.docx" file and incorporate it in the report.

![Microsoft Word integration showing fit notes document with formatting capabilities](/files/F3Ba7bijsWuhWNR8jIVP)

Note that you can add images, tables etc to your document in Word, and they'll be copied into your fit report. You can easily incorporate:

* Screenshots from any other software you're using in your fit (TIP: use Windows logo key + Shift + S to invoke the Windows Snipping Tool, or consider a tool like SnagIt Editor to easily draw on the screenshot)
* Screenshots from any parts of Velogic Studio that aren't already automatically included in the report (e.g. comparisons between positions that aren't initial/final positions)
* Voice dictation - save time typing up notes by dictating using Microsoft Word's built-in dictation feature.

If you're using OneDrive to store your fits (which we highly recommend), and you use Office365, you can even open the "fit notes.docx" file on your mobile phone using the mobile version of Microsoft Word. This means you can take photos from your phone and incorporate directly into the document, and you can use the mobile voice dictation features of your phone to dictate directly into your document. OneDrive will sync changes from your phone to your PC, so that they can be incorporated into the Velogic Studio report.

![Mobile Word app integration for adding photos and voice dictation to fit notes](/files/hmw5aG0T6vLQVIPfqxxH)

### ![Additional report customization options and settings](/files/QfFScK8rPAicTJPZousy)

### Bike measurements pages options

![Bike measurements page options for including measurement wand data](/files/KVF1XIZ0GK6W09ExJtOp)

If you've taken measurements with the measurement wand, or entered them manually, the results can be included on the report with these 2 options.

![Initial bike measurements page showing baseline position data](/files/HirBB8TMqRcuhAx0xWTO)

![Final bike measurements page showing adjusted position specifications](/files/NuTaUI08HXznsVAEdfKT)

### Analysis pages options

![Analysis pages options for including specifications, comparisons, and body metrics](/files/xMCwKJW8decphcQfc2aM)

These options allow you to include or exclude specific pages related to Velogic Studio's analysis.

#### Specifications page

![Specifications page showing textual bike specifications with highlighted changes](/files/FgN9TU85nZ4rSr6gqfxP)

When you add measurements, you have the option to add textual specifications too. If you take multiple measurements, any changes will be highlighted in the second column.

#### Comparison pages

![Side-by-side comparison pages showing initial and final positions from multiple camera angles](/files/4i4P9nP7UNArzQtIufOW)

Each image that Velogic Studio captures for the initial and final position can be shown in side-by-side format. Note that you can use multiple webcams placed in multiple positions around the rider, so this can be useful to demonstrate changes from those viewpoints.

#### Body metrics pages

These pages show each of the many metrics that are automatically calculate by Velogic Studio.

For each metric, Velogic Studio shows a concise explanation, the initial and final values, and the change between initial & final.

![Body metrics page displaying calculated measurements with initial, final values and changes](/files/cCio2NQaewTEYnwiPNLD)

### Report generation options

These options control when the report is generated, and whether to automatically save to PDF and/or DOCX when the report is generated:

![Report generation options for manual or automatic generation with PDF/DOCX save options](/files/kvMrEcgrRPsb1Hp9ce8l)

When set to "Manual", you can click "Generate report" in the actions list on the right-hand side whenever you would like a report generated.

When set to "Automatic", the report will be generated whenever you move into Step 3, and whenever you change the report generation options while in Step 3.

## Report actions

The right-hand side of screen shows additional actions you can take with the report:

![Report actions panel showing generate, save, zoom, print, and folder access options](/files/yADcOrNEx4nbhqUrgWMm)

* "Generate Report", "Save PDF" and "Save DOCX" actions will only be visible if the Report Generation options (above) are set to Manual.
* "Zoom In", "Zoom Out", "1 Page", "2 Pages" actions affect how the preview is displayed on-screen.
* "Print" sends the report to your printer
* "Open Folder" opens the folder containing all artefacts from this fit (videos, images, report, fit notes.docx, fit.session)
* "Restart" will close and restart Velogic Studio, ready for the next fit.

### .pdf vs .docx report

Velogic Studio can save the report in .pdf and .docx format:

* The .pdf format is useful to send directly to your customer, because their browser/phone/computer will have built-in PDF viewing capability, and they can print it to paper if they wish.
* The .docx format allows you to add to the report after the fit, if needed. For example, you might do some research into suitable new bike options - you could do that using Microsoft Word, and generate the PDF manually afterwards.

> **Important:** If you make changes to the .docx version of the report, you should save it with a different filename - so that it's not overwritten if you recreate the report in Velogic Studio

> **Tip:** Instead of editing the report .docx file directly, you might consider using the "Summary from word" feature (see Commentary section above). This will give you a "fit notes.docx" file, into which you can add any extra information (such as bike options), and the content will be automatically incorporated into the report the next time it is generated.

# ANT+ Overview & Troubleshooting

How to configure and troubleshoot ANT+ sensors for heart rate, power, and muscle oxygenation data in Velogic Studio.

If you have a ANT+ USB device plugged into your computer, Velogic Studio can use it to communicate with ANT+ sensors close to your computer.

## What does ANT+ support look like in Velogic Studio?

Step 1 of Velogic Studio is the configuration step. There's a section to help you configure ANT+. If you have an ANT+ device already plugged into your computer, you'll see this:

![ANT+ configuration section in Step 1 showing device detection interface](/files/X5Wt9qX8L6TSxxaNn6pq)

... and after a few seconds, you'll see which sensors it found. If it didn't find any sensors, you'll see this:

![ANT+ interface showing no sensors found message with RESCAN button](/files/a748rN6SQjnCLcOXBSk9)

If you do have sensors, but they're not found, check that they are turned on and press RESCAN.

When sensors are found, they'll look like this:

![ANT+ sensors detected showing heart rate, power, and muscle oxygenation options](/files/Ok48hs4977HgQlrUNFcN)

You may see all of these, some, or none, depending on which sensors are actually found by the scan.

If there is more than one sensor of each type, you can select which sensor to connect to - they don't have meaningful names, but you can select each one and find the one that is giving data that matches what you would expect:

![ANT+ sensor selection interface with multiple devices of same type available](/files/aWGhdPolDcRxz6YGVdEs)

If you don't want to see data from one of the sensors, you can tell Velogic Studio to ignore it by turning off the checkbox (slider) next to that sensor.

In step 2, ANT+ data will be shown live, and will automatically be captured for each capture period, so you can compare along with all of the other data:

![Step 2 live ANT+ data display showing real-time sensor values during capture](/files/fWoOi5vs91fqAiYpHClP)

The values from the first and last capture are also automatically included in the report:

![ANT+ sensor data automatically included in fit report with first and last capture values](/files/XlvRfl99zsXVeV9aitLc)

> **Note:** The values in the report above aren't sensible values - they were created with a simulation tool for documentation purposes.

## ANT+ FAQ

### Q. Which dongle should I use?

Velogic Studio interfaces with your ANT+ sensors via a small USB adaptor (also known as a "dongle"). There are many of these on the market now, we have purchased several brands and unbranded versions and haven't yet met one that didn't work. You can search for [ANT+ USB dongles on Amazon](https://www.amazon.com/s?k=ANT%2B+USB+dongle) - they're inexpensive so you might as well buy a spare or two at the same time.

### Q. Can I connect with Bluetooth instead of ANT+?

A. Yes! Velogic Studio now supports Bluetooth Low Energy (BLE) sensors for heart rate, power, and cadence. See the [Bluetooth Overview](/section-02-using-velogic-studio/bluetooth-overview) for details on configuring Bluetooth devices. You can use ANT+ and Bluetooth sensors simultaneously if needed.

Each protocol has its advantages:

* **ANT+** - A single USB dongle can connect to multiple sensors; supports muscle oxygenation sensors
* **Bluetooth** - Built into most modern computers (no dongle required); simpler setup

### Q. Can I control my trainer's resistance with Velogic Studio?

A. Not currently. This is called "FE-C" and there are more and more trainers which support control via this protocol. The list of trainers that support FE-C is available [here](https://www.thisisant.com/directory/filter/~/67/~/267/) - if you have a compatible device, and you would like to be able to control it from Velogic Studio, please get in touch.

## Troubleshooting ANT+ support

### Check that your ANT+ USB device is visible in Device Manager

You should see an entry like this in Device Manager:

![Device Manager showing properly installed ANT USB-m Stick under USB controllers](/files/ZgjGBiyEuIjcoMsq1RLk)

If you can't see that entry (or a similar one), try replugging into a different USB port.

If you see the "ANT USB-m Stick" entry under "Other devices", like this:

![Device Manager showing ANT USB-m Stick under Other devices requiring driver installation](/files/OdS0dLfWrL8GUYUdFOfE)

... then you can follow [this guide](https://support.wahoofitness.com/hc/en-us/articles/360021559679-Installing-ANT-drivers) to install the drivers manually.

If you can't see any entries in Device manager related to your ANT+ USB device, you might consider purchasing a different device.

### Check that Velogic Studio can see your ANT+ device

If you can see your device in Device Manager, but Velogic Studio shows this message:

![Velogic Studio error message indicating ANT+ USB device cannot be utilized](/files/WuwBYMs3ykYpkxVg390t)

... then Velogic Studio is unable to utilise your USB ANT+ device. Please contact us to help you troubleshoot further; email <contact@velogicfit.com> with a screenshot of your USB device's name in Device Manager.

### Check that Velogic Studio can connect to your ANT+ sensors

If you have a heart rate sensor, power sensor, or muscle oxygenation sensor that is powered on but is not detected by Velogic Studio, please first check that your device is actually a compatible ANT+ device.

The list of compatible devices is available from the ANT+ website:

* [Compatible power sensors](https://www.thisisant.com/directory/filter/~/~/~/95/)
* [Compatible heart rate sensors](https://www.thisisant.com/directory/filter/~/~/~/109/)
* [Compatible muscle oxygen sensors](https://www.thisisant.com/directory/filter/~/~/~/240/)

We don't own every single device on those lists obviously - we test with representative devices and simulation software provided by ANT+.

If your device is compatible but is not being detected by Velogic Studio, please contact us for support; <contact@velogicfit.com>


# Bluetooth Overview

How to configure and troubleshoot Bluetooth sensors for heart rate, power, and cadence data in Velogic Studio.

> **Pre-release Feature:** Bluetooth sensor support is currently in pre-release. The information on this page applies to pre-release versions of Velogic Studio and may not yet be available in the shipping version. Features and functionality may change before the final release.

Velogic Studio can connect directly to Bluetooth Low Energy (BLE) sensors to capture heart rate, power, and cadence data during your bike fitting sessions.

## What does Bluetooth support look like in Velogic Studio?

### Enabling Bluetooth Support

Before using Bluetooth sensors, ensure the Bluetooth plugin is enabled:

1. Go to **Settings** (click the "SETTINGS" link in the Rider Details panel)
2. Select the **Plugins** tab
3. Ensure the **Bluetooth** toggle is turned on

### Configuring Bluetooth Sensors

Step 1 of Velogic Studio is the configuration step. There's a **BLUETOOTH** section that helps you configure your Bluetooth sensors.

When Velogic Studio starts, it automatically scans for nearby Bluetooth sensors:

![Bluetooth configuration section in Step 1 showing device scanning](/files/aw22ZBfwEOcaFeKt2XNc)

After the scan completes, any detected sensors will be shown. You can configure which sensor types to use:

![Bluetooth sensors detected showing power and cadence options with device selection](/files/g20sb8tj6ydTkEidey2O)

The Bluetooth section shows:

* **Service toggles** - Enable or disable Heart Rate, Power, or Cadence data collection
* **Device selection** - When multiple devices support the same service, you can select which device to use
* **Live data** - Real-time values from connected sensors are displayed during configuration
* **Device count** - Shows how many Bluetooth devices were found
* **RESCAN** - Click to scan for devices again if your sensor wasn't detected

### Supported Sensor Types

Velogic Studio supports the following Bluetooth Low Energy (BLE) services:

| Service                       | Description                                                   | Data Captured                    |
| ----------------------------- | ------------------------------------------------------------- | -------------------------------- |
| **Heart Rate**                | Heart rate monitors using the standard BLE Heart Rate Service | Heart rate (BPM)                 |
| **Cycling Power**             | Power meters using the standard BLE Cycling Power Service     | Power (W), Power Balance (L/R %) |
| **Cycling Speed and Cadence** | Cadence sensors using the standard BLE CSC Service            | Cadence (RPM)                    |

### Live Data During Capture

In Step 2 (Capture), Bluetooth data is shown live in the Motion Metrics panel on the right side of the screen:

![Step 2 showing Bluetooth data in the Motion Metrics panel](/files/bLuhHW0QieBquKuE6S1W)

The Bluetooth metrics are grouped under the "Bluetooth" heading and include:

* **Cadence** - Current pedaling cadence in RPM
* **Heart Rate** - Current heart rate in BPM
* **Power** - Current power output in watts
* **Power Balance** - Left/right power distribution percentage

This data is automatically captured for each capture period, allowing you to compare sensor data alongside motion metrics and video.

## Bluetooth FAQ

### Q. Which Bluetooth sensors are compatible?

A. Velogic Studio supports any Bluetooth Low Energy (BLE) sensor that implements the standard GATT profiles for Heart Rate, Cycling Power, or Cycling Speed and Cadence. This includes popular devices from manufacturers like:

* Garmin
* Wahoo
* Polar
* Favero
* 4iiii
* Stages
* SRAM/Quarq

### Q. Can I use ANT+ sensors instead?

A. Yes! Velogic Studio also supports ANT+ sensors. See the [ANT+ Overview](/section-02-using-velogic-studio/ant-plus-overview) for details on configuring ANT+ devices. You can use ANT+ and Bluetooth sensors simultaneously if needed.

### Q. Why use Bluetooth instead of ANT+?

A. Bluetooth has some advantages:

* **Built-in support** - Most modern computers have Bluetooth built-in, so no additional USB dongle is required
* **Wider device support** - Many newer sensors support Bluetooth in addition to (or instead of) ANT+
* **Simpler setup** - No driver installation needed for the USB dongle

However, ANT+ has its own advantages (multiple simultaneous connections with a single dongle), so choose whichever works best for your setup.

### Q. Can I connect multiple sensors of the same type?

A. By design, Velogic Studio connects to one device per service type. If multiple devices are found that support the same service (e.g., two power meters), you can select which one to use from the dropdown menu.

### Q. Does Velogic Studio support smart trainer control?

A. Not currently. Velogic Studio can read data from your smart trainer's power and cadence sensors, but does not control trainer resistance. If trainer control would be useful for your workflow, please contact us.

## Troubleshooting Bluetooth Support

### Sensor not detected during scan

If your Bluetooth sensor isn't being detected:

1. **Check the sensor is powered on** - Many sensors enter sleep mode when inactive. Wake them up by moving the crank (for power/cadence) or putting on the heart rate strap.
2. **Check the sensor is in pairing mode** - Some sensors need to be put into pairing mode. Check your sensor's documentation.
3. **Check Bluetooth is enabled on your computer** - Open Windows Settings > Bluetooth & devices and ensure Bluetooth is turned on.
4. **Move closer to the sensor** - Bluetooth range is typically 10 meters, but can be reduced by obstacles or interference.
5. **Try rescanning** - Click the "RESCAN" button to scan for devices again.
6. **Check for interference** - Other Bluetooth devices, WiFi routers, and USB 3.0 devices can cause interference. Try moving these away from your sensors.

### Sensor shows as connected but no data appears

If your sensor is connected but you're not seeing data:

1. **Start pedaling** - Power and cadence sensors only transmit data when there's movement.
2. **Check sensor battery** - Low battery can cause intermittent connectivity or missing data.
3. **Check the service toggle** - Ensure the toggle for that sensor type (Heart Rate, Power, or Cadence) is enabled in the Bluetooth configuration section.

### Data appears intermittent or choppy

If data is dropping in and out:

1. **Check for interference** - Move other wireless devices away from the sensor and computer.
2. **Check sensor battery** - Replace the battery if it's low.
3. **Reduce distance** - Move the sensor closer to the computer if possible.

### Bluetooth adapter not working

If Bluetooth isn't working at all on your computer:

1. **Check Device Manager** - Open Device Manager and look for "Bluetooth" in the device list. Ensure there are no warning icons.
2. **Update drivers** - Right-click on your Bluetooth adapter in Device Manager and select "Update driver".
3. **Restart Bluetooth** - Turn Bluetooth off and on again in Windows Settings.
4. **Try a USB Bluetooth adapter** - If your built-in Bluetooth is problematic, a USB Bluetooth 4.0+ adapter can provide better compatibility.

# Using multiple Kinect cameras

How to set up and use multiple Microsoft Kinect cameras for bilateral capture in Velogic Studio

Microsoft Kinect cameras have always had an inbuilt limitation: it's only possible to attach a single Kinect camera to Windows at one time.

When we developed Velogic Studio 4 (released early 2024), one of the major enhancements was the ability to use multiple Femto Mega cameras simultaneously, for full bilateral capture.

Although simultaneous bilateral capture isn't possible with the Microsoft Kinect camera (due to the Windows limitation), it is now possible to use multiple Kinect cameras to capture both sides of a rider, without needing to rotate the rider.

It's not simultaneous, but it's still a better workflow than physically rotating the rider on the platform. Here's how it works:

## Setup Process

1. **Enable Multiple Camera Mode** In Step 1 of Velogic Studio, look for this option at the bottom of the Kinect configuration section:\
   ![Multiple camera mode toggle option at bottom of Kinect configuration section](/files/DnA8ZOsibcFD4ycKq6oA)
2. **Configure First Camera** By default, that option will be off, but when you turn it on, you will see some differences in the configuration panel:\
   ![Kinect configuration panel showing camera naming and remove button with multiple camera mode enabled](/files/596sXrwhKFimpVnRTIoB)
   * The Kinect camera now has a unique "name". This is initially set to the unique internal serial number from the camera, but you can click "Rename" to rename it to something more appropriate, e.g. "Right" or "Left"
   * There's a "Remove" button, which you can use to remove this camera.
3. **Add Second Camera** If you now unplug that Kinect camera, and plug in a different camera, you'll see two configuration panels, one for each camera:\
   ![Two Kinect camera configuration panels displayed after second camera is connected](/files/bwXu0AvjxOzhXPs2UZRt)
4. **Rename the Second Camera** You should rename the second camera too for easier identification.

## Capture Workflow

Now that Velogic Studio knows about both cameras, you can complete a capture with each camera, and Velogic Studio will give the captured videos different names, according to the names of the cameras.

## Merging Captures

When you have completed two captures, e.g. one with the left and one with the right camera, you can mouse-over the thumbnail of the second capture, and click the "Actions" button:\
![Capture thumbnail with Actions button visible when hovering over second capture](/files/d1OiBwl5a4M5yg2LAxga)

... and then choose "Merge with previous" from the dropdown options:\
![Actions dropdown menu showing Merge with previous option for combining captures](/files/lj0Dg7yqKVNazQemPfGt)

Velogic Studio will merge together the 2 captures, and you'll then have a single capture with both Right and Left videos and metrics.


# Webcams: Overview, FAQ, troubleshooting

Complete guide to configuring, using, and troubleshooting webcams with Velogic Studio, including camera recommendations and setup instructions.

Velogic Studio can show a liveview of, and record video from, any webcams that you have attached to your computer.

## How to configure webcams

Step 1 of Velogic Studio is the configuration step. There's a section in step 1 to help you configure your webcams.

If you don't have any webcams attached to your PC, you'll see this:\
![Webcam configuration section showing no webcams attached message](/files/ViVt5hJwWZOVz5f37fNQ)

If you plug in a webcam, it will be detected (but not added) automatically:\
![Webcam detected automatically with Add Webcam button available](/files/1LbSf9jHu7UJjtqKZFk8)

When you click the "Add Webcam" button, a popup will appear allowing you to choose which webcam to add:\
![Add webcam popup dialog showing available webcam selection options](/files/Kzozcn4wBCa6t9yawOnS)

Click on the webcam you'd like to add, and you'll see a configuration card added for that webcam:\
![Webcam configuration card showing live view and control options for renaming, rotation, resolution](/files/a8DzJnQbYQUYNneWQOCA)

The configuration will show the live view from the webcam, and there are controls for you to:

* Rename the webcam (e.g. "Frontal") - the name is used in Step 2 and in the report, so it's recommended to rename to something that makes sense
* Rotate the webcam - particularly useful for frontal view, where you can mount the camera on its side to get the best view of the rider
* Set the resolution and frame rate - a higher resolution will be clearer, but will also mean larger video files, and will take more computer resources as the videos are recorded.
* Capture an image (snapshot) when the knee is at maximum extension during the capture period, as determined by the Kinect camera. This is available for review & will appear in the report.
* Remove the webcam (disconnect it from Velogic Studio)

## Webcams FAQ

### Q. Which webcam should I buy?

Any webcam supported by Windows should work with Velogic Studio. The following cameras have been tested and known to work:

* [Logitech C920 Webcam](https://www.amazon.com/Logitech-Widescreen-Calling-Recording-Desktop/dp/B006JH8T3S/ref=sr_1_3?crid=7HXRLXJAI63K\&keywords=c920\&qid=1646783213\&sprefix=c9%2Caps%2C247\&sr=8-3) - mainstream webcam. There is also a C922 variant which is appealing because it claims to offer 60FPS; in practice, many people report difficulty getting 60FPS from the camera, and end up using 30FPS.
* [Microsoft Modern Webcam](https://www.amazon.com/Microsoft-2019-Modern-Webcam/dp/B093CBVYNL/ref=sr_1_3?crid=1XW7UVQFR2UJS\&keywords=microsoft+modern+webcam\&qid=1646783294\&sprefix=microsoft+modern+webcam%2Caps%2C318\&sr=8-3) - small and inexpensive
* [Dell WB7022](https://www.dell.com/en-us/shop/dell-ultrasharp-webcam/apd/319-bbhp/pc-accessories) - great image quality. Sometimes the drivers seem to get "stuck" and the camera needs to be unplugged and replugged.
* [Logitech Mevo Start](https://www.amazon.com/Logitech-Wireless-Streaming-Quality-Intelligent/dp/B0866PZN76) - wireless streaming webcam, which can be configured to work via NDI protocol (over your local wifi network) - see "Can I use my phone as a camera?" below.

If you have experience with any other webcam models, good or bad, please let us know and we'll add to the list.

### Q. My webcam needs to be further away from my PC - can I use an extension cable?

Most consumer webcams come with short USB cords. The Logitech C920 USB cord is around 1.4m long. If you're going to place this camera further that that from your computer's USB port, an extension cord is necessary.

We have had great experience with [Cable Matters 10m USB3.0 extension cable](https://www.amazon.com/Cable-Matters-Active-Extension-Female/dp/B00DMFFL2W/ref=sr_1_3?crid=3CJY9GF0R3NZS\&keywords=Cable+Matters+10m+USB3.0+extension+cable\&qid=1646784303\&sprefix=cable+matters+10m+usb3.0+extension+cable%2Caps%2C399\&sr=8-3). There was previously a 5m version available that also works great. This cable is powered at the remote end (camera), but it seems to work well even unpowered with the Logictech C920 camera; presumably because it's just a very high-quality cable. Note that the Cable Matters cable will also extend a Kinect v2 camera.

Occasionally we've seen this extension cord + camera combination get into a state where it won't start. This can be solved by turning off & on again the power supply to the cable (it's plugged into the camera end of the cable)

### Q. Can I use my phone as a camera?

Yes! There's a protocol called [NDI](https://en.wikipedia.org/wiki/Network_Device_Interface) which allows high-quality video to be transmitted over your local network. Here's how to set it up:

1. Install the [NDI HX camera app](https://ndi.video/tools/ndi-hx-camera/) on your phone (it's not free, but it's less expensive than a webcam)
2. Install the [NDI Tools](https://ndi.tv/tools/) software on your PC

Then each time you want to use it:

1. Run the NDI HX camera app on your phone
2. Run the NDI Tools software on your PC and choose the "Webcam Input" option:\
   ![NDI Tools software interface with Webcam Input option for phone camera integration](/files/g51o09I7wGdYYCWk6uYu)
3. You should now have an NDI app in the system tray (bottom-right of your Windows desktop). Right-click it and make sure there's a tick next to the name of your phone:\
   ![Windows system tray NDI application with phone selection for enabling video feed](/files/u0XxBdfqecLw3tu4XOwD)
4. You can now add it to Velogic Studio by clicking the "Add camera" button, and use it as if it's a normal webcam.

Note that we can't offer you support in configuring your network for NDI. If it doesn't "just work" for you, please refer to the [NDI resources page](https://ndi.video/resources/) for troubleshooting guides. You should use the NDI Studio Monitor Tool to test the feed from your phone; if it can see video from the phone camera, then Velogic Studio should be able to.

## Troubleshooting webcams

### If the camera isn't available to add in Velogic Studio

The first step in troubleshooting a webcam in Velogic Studio is to make sure that it works well with Windows generally, and with other apps.

Windows 11 has a nicer camera-management interface than Windows 10. In Windows 11, you can use the "Manage cameras" interface:\
![Windows 11 Manage cameras interface showing connected camera devices](/files/tRjUDT9NnDiGMpm1pk8N)

(Note that although the Kinect V2 can be used as a webcam by Windows, Velogic Studio will instead use it to detect joints and for measurement, so it can't be used as a normal webcam).

If you click on one of the cameras, you can adjust the settings for the camera:\
![Windows camera settings page with preview image and camera adjustment controls](/files/ACRTsOA6shyrWm3eASz1)

If you can see the preview image in this settings page, then you should be able to add the camera in Velogic Studio.

### If you can add the camera in Velogic Studio, but it doesn't start

If you see this:\
![Velogic Studio webcam error showing camera detected but unable to start message](/files/G71mLBeAcWFylSQBXeZt)

... that means that Velogic Studio can see the camera (i.e. Windows is reporting that the camera is connected), but can't start it.

The most likely cause is that another app (e.g. Zoom) has exclusive control of the camera. Velogic Studio also demands exclusive control of the camera, so you can't use it with Zoom at the same time as Velogic Studio. You can try to close the other app, or restart your computer.

You can also try to unplug and replug the camera.

Note that some cameras sometimes get into a state where they are on, but no apps are using them. This is known to happen with the Dell WB7022 camera, and can be fixed by unplugging and replugging the camera.

# Extra tips

Helpful tips and tricks for using Velogic Studio effectively, including calibration guidance and webcam configuration

## General Tips

* If you choose to switch sides during a fit you will need to click the calibrate button below the liveview screen every time you change sides
* If you wish to perform a quick fit you can use this system without calibrating. It will only offer the angular metrics so essentially has the same function as our 2D Motion system
* A little bit of inconsistency in the wireframe will not affect your data unless the flicker is happening at the top or bottom of the pedal stroke every time
* It doesn't matter if the wireframe is out of sync with the riders motion at any point as the measurement functions are a separate process to the one that draws the wireframe. The wireframe is just an additional feature to help with visualisation
* If you have issues with the system at any point, please capture a sample file (detailed in Troubleshooting) and take screenshots, we will struggle to resolve your issue without good information.

## Turning off webcams

The system supports webcams to capture additional views of the rider. At this stage it is not possible to use a second Kinect as a secondary camera.

You can choose from available cameras in the 'Settings' menu. This is useful for turning off integrated front facing webcams if they are not part of your rider capture setup.\
![Camera settings menu showing available webcam selection options for configuration](/files/CWIJOOVptSKV6D2TxXV2)

Once you are in the capture screen you can choose which view is the primary by clicking on the tile below the liveview

We have tested with Logitech and Microsoft Webcams and recommend 1080P, 30fps models to match the image clarity of the Kinect. We have not tested wireless webcams or using the streaming video functions from mobile devices.

The video saved during a capture will be the one showing in the main view. So you can save a frontal video by running a capture with that view selected.


# Calibration

Learn how to calibrate the bike position relative to the camera for accurate measurements in Velogic Studio

Calibration is a process which accurately defines the location and orientation of the fit bike relative to the camera, so that measurements taken during the fit are as accurate as possible.

The 5 points that are captured allow us to correct for pitch, yaw and roll so it doesn't matter whether the bike or camera is level or perfectly aligned.

To begin calibration click the button at the bottom of the liveview:

![Velogic Studio live view with calibration button at bottom for starting the 5-point calibration process](/files/2mwPNUZEkAHOwSk803yC)

The calibration popup window will appear. You will use the wand to acquire specific points on the bike (or fit bike). The in-system help will guide you through the required locations.

The current point will be highlighted in Orange text, once the system has acquired that point the text becomes green and moves to the next location.

The system waits until the wand has been steady for 30 samples before acquiring a point. This usually only takes 1 second so it is advisable to cover the locator triangles until the wand is in position.

If you are finding that the system is not picking up a point you may need to alter the angle of the wand until the Kinect can recognise it properly.

The system will not collect another point within 50mm of the last one so there is no risk in holding the wand in one location for too long.

## Calibration Process Videos

This video illustrates the calibration process on a trainer:

{% embed url="<https://vimeo.com/1094843151>" %}

And this video illustrates the process on a size cycle (it's using the older Kinect wand, but the process is the same for Orbbec cameras and the blue wand):

{% embed url="<https://vimeo.com/377207211>" %}

Here are some more hints & tips for each point:

## 1. Stem bolt

![Calibration point 1: measurement wand positioned at stem bolt center with pink triangles visible to camera](/files/HFlG4k6dV1U2ff6sODXZ) *Stem bolt calibration point*

Place the tip of the wand at the centre of the headset compression cap bolt. If you are working with bars that obscure the headset cover you will need to mark the centreline of the stem (with tape) to acquire this point. If you are using a fit bike this point just needs to be in the same plane as the next two measurements.

## 2. Centre of saddle

![Calibration point 2: measurement wand positioned at center of saddle using green saddle jig for accurate placement](/files/HpkaRvg903LnDoZErukP) *Centre of saddle calibration point*

Place the tip of the wand at any point along the centreline of the saddle, (use your supplied green saddle jig). If using a fit bike this can be a point on the bike that is in plane with point 1 and 3.

## 3. Low midline point

![Calibration point 3: measurement wand positioned at low midline point on bike frame, typically at bottle boss location](/files/wx48a0vARDF8BpE9RLdb) *Low midline calibration point*

Place the wand at a point that is on the centreline of the bike, low down on the frame (bottle bosses are a good choice). The Kinect only needs to have line of sight to the pink locator triangles, it doesnt matter if the actual tip of the wand is obscured by a bottle cage or cable. If you are using a fit bike this point needs to be in plane with points 1 and 2.

## 4. and 5. Front and rear pitch points

![Calibration point 4: measurement wand positioned at front pitch point, typically at front wheel axle or equivalent height reference](/files/mKFOrYEPWBDaQu7YJT8h) *Front pitchpoint calibration point*

![Calibration point 5: measurement wand positioned at rear pitch point, typically at rear wheel axle for establishing bike level reference](/files/1YLlWonu1YK7IBw7ylhQ) *Rear pitchpoint calibration point*

The pitch points are two locations of equal height (when the bike is on level ground). These points are used to correct for the camera being rotated relative to the bike - either because the camera is rotated on its mount, or because the bike is pitched up or down at the front or back, e.g. because it's mounted on a stationary trainer.

The wheel axles are a good choice if both can accessed - in which case you would choose the front wheel skewer for the front pitch point and the rear for the rear pitch point.

If you're using a fit bike (which doesn't have axles), it's likely that the bike is always level relative to the ground - so you can use a point on the floor in front the bike for the front pitch point; and on the floor behind the bike for the rear pitch point.

### Using a Wahoo Kickr Bike

For fit bikes like the Wahoo Kickr that don't have traditional front and rear axles, you can take the pitch points from the floor:

![Wahoo Kickr bike showing calibration pitch points taken from floor in front and behind the bike](/files/EflBvobJ84wopgBrMniP) *Wahoo Kickr bike - pitch points can be taken from the floor*

* Use a point on the floor in front of the bike for the front pitch point
* Use a point on the floor behind the bike for the rear pitch point
* Ensure both points are approximately in line with the plane of the bike

Once the process is complete click the "Finish" button.

## Calibration FAQ

### Q. What if I don't calibrate?

Calibration is always required if you're going to use the wand to measure the bike. Otherwise, it's optional.

If you **don't calibrate**:

* You won't see the **Sitting Angle** body metric (because that references the bottom bracket, which is established during measurement; and measurement always requires calibration).
* **Most of the body metrics will still be very accurate**, especially the basic joint angles (because these are measured between points in 3D space, so the camera orientation does not matter)
* **Some of the body metrics will be less accurate** IF the bike has pitch, roll or yaw relative to the camera:
  * Hip-to-foot (will be less accurate if the bike has "yaw", "pitch" or "roll" relative to the camera)
  * Knee-over-foot (will be less accurate if bike has "yaw" relative to camera)
  * Torso angle, forearm angle, and arm angle (will be less accurate if the bike has "pitch" relative to the camera i.e. front and rear axles aren't level relative to the camera)
  * Knee travel angle and knee lateral travel (will be less accurate if the bike has "roll" relative to the camera)
* **Knee tracking visualisation will be less accurate** - e.g. if the camera is angled down towards the rider's legs, the knee track will appear to be on an angle even if the rider's knee is actually travelling completely vertically.

... so, if you're not going to calibrate, you should try to ensure that the camera and bike are both level with the ground, and the camera is pointing directly at the bike (i.e. not on an angle left/right or up/down).

### Q. How can I check calibration?

In Velogic Studio v4, we added a [Calibration Review step](/section-03-calibration-and-measurement/calibration-review) for this purpose.


# Calibration review step

Understanding and reviewing calibration results in Velogic Studio v4, including 3D visualization of bike plane and camera alignment.

[Calibration](/section-03-calibration-and-measurement/calibration) has always been a little mysterious in Velogic Studio. What do the points mean? How do you know if you took them in the right place?

Velogic Studio v4 now has a new step in the Calibration and Measurement wizards to show you the results of the Calibration step, so you can quickly see if you've completed the calibration correctly or not.

After you've taken the 5 calibration points, you'll see a new Calibration Review step:

![3D calibration review visualization showing bike plane, pitch points, and camera alignment in interactive 3D space](/files/RHNh05CeFWZmdXsX6fKf)

This can look quite bizarre at first glance, but you will quickly become familiar with it and how to use it.

If you click anywhere on the main 3D image and move your mouse (while holding the mouse button down), you'll see that you can drag the 3D image viewpoint around:

{% embed url="<https://ik.imagekit.io/vfframes/docs/drag-calibration_Ezi_FF4gm.mp4?updatedAt=1712790635001>" %}

You can also use the mousewheel to zoom, and the right mouse button to drag the camera position.

What you are looking at is a 3D "snapshot" of the bike in your studio, with a visualisation of how Velogic Studio is using those points to establish the relationship between the camera and the bike. Let's dig in!

## The bike plane

The first 3 points taken during calibration form a triangle, and the triangle is used to establish the "plane" of the bike. This is represented as a blue square in the visualisation, and you should see that the blue square sits in line with the frame of the bike as you drag left/right:

{% embed url="<https://ik.imagekit.io/vfframes/docs/bikeplane_mZs8RryHF.mp4?updatedAt=1712790707365>" %}

If the blue square is on an angle, or doesn't seem to line up nicely with the bike, you should go back and redo the calibration.

## The pitch points

The last 2 points taken during calibration form a line or bar, which is used to establish the "pitch" of the bike, relative to the camera.

![Calibration review interface showing pitch points visualization with green and orange calibration markers on bike frame](/files/KOakU0jpvhoWSw1nUV3L)

If the bar doesn't look like it connects the 2 pitch points you took during calibration, you should go back and redo the calibration.

## Ideal vs Actual cameras

When you first move onto this step of the wizard, the virtual 3D camera will be positioned as if at the front of the bike, looking along the bike. This is to allow you to quickly see if the bike plane looks correct.

You can click on different predefined camera viewpoints by using the links on the right-hand side of the screen:

![Camera viewpoint selection panel showing options for Actual camera, Ideal Driveside camera, and other preset viewing angles](/files/yIAiuijLobwHyx8aiX1s)

If you click on "Actual camera" and then "Ideal Driveside camera" (or "Ideal Non-Driveside camera", depending on which side your camera is on), you will see a slight change in the viewpoint:

{% embed url="<https://ik.imagekit.io/vfframes/docs/actualcam_Q1-vgu5tW.mp4?updatedAt=1712790793395>" %}

The "ideal" camera position has been calculated by Velogic Studio, using the calibration points. The "ideal" camera should be:

* directly facing the bike plane (to adjust for yaw or roll of the bike, relative to the camera)
* rotated so that the pitch bar (between the two pitch points) is level from the camera's point of view.

This is really the heart of what the calibration system is doing; it's adjusting for any misalignment of the camera with respect to the bike, so that measurements are as accurate as possible.

To further illustrate this, if you click on the "Actual camera" link and then use the mousewheel to zoom out slightly, you will see a virtual representation of both the Actual camera and the Ideal camera in the 3D scene:

![3D scene showing both actual and ideal camera positions relative to bike frame for calibration accuracy assessment](/files/FExfJmvFDTv8X8mrtcCO)

If the actual camera was perfectly positioned relative to the bike, the actual and ideal camera would overlay each other.

## Checking calibration numerically

On the right-hand side of this step, you can see some numeric values which quantify the relationship between the camera and the bike:

![Calibration numeric values panel showing quantified relationship measurements between camera and bike orientation](/files/g43K4b7aMvo60JUEYg4M)

With practice, you will be able to tell whether these numbers match your expectations. If your camera was perfectly flat and level to the ground, and perfectly at right-angles to the bike, and the bike was perfectly upright on the ground and perfectly level - then these numbers would all be 0.

Note that it's OK for the numbers not to be zero; calibration establishes what those numbers are, so that the measurement process can adjust for them mathematically.

## After reviewing calibration

Once you are happy with the calibration points, you can click "Finish" to finish the calibration, or click "Next" to continue (if you were calibrating before measuring).


# Taking bike measurements

Step-by-step guide for using the measurement wand to capture bike geometry measurements for road, triathlon, and mountain bike setups.

On the capture screen you will see a button for "MEASURE BIKE": ![Velogic Studio capture screen showing MEASURE BIKE button for initiating bike geometry measurement process](/files/IAIBb4YdF3JAfK3ftgg6)

Clicking "MEASURE BIKE" will open the bike measurement popup window:

![Bike measurement popup window with instructions for using measurement wand to capture specific frame geometry points](/files/aLCYEA8bi8Ry0r99UKji)

Follow the instructions on screen to use the wand to acquire the indicated points. Once you have acquired a point a red dot will appear on the image. If the dot is not aligned with the image you can click "Redo" to re-acquire.

Measurement points differ slightly between road, mountainbike and tri disciplines. This document will show all Road measurement points, and then points which differ for mountainbike and tri disciplines.

## Road

![Bar end near drop measurement point showing wand positioned at drop bar end for handlebar width measurement](/files/mbD8vlDePXOfIcahrfJ3)\
\&#xNAN;*Bar end near drop measurement point*

If the diameter of the bars is something other than 31.8mm use the drop down box at lower left to select a value. If the bar diameter isn't in the list, choose "Custom" and manually type the bar diameter.

![Bar diameter selection dropdown showing options for different handlebar sizes with custom input option](/files/2KjsiXNueMA2wOV3mFC4)

When all measurement points are captured, and the bar diameter is correct, click Next.

On step 2 you will see the bike measurements as well as free text fields to record bike details:

![Bike measurements results screen showing calculated geometry values and free text fields for recording bike setup details](/files/rHHOhyCavULb74t8PR14)

You can manually alter the bike measurements by clicking on the field. For instance - many road handlebars have flared drops so it is hard to get an accurate measurement when comparing tops and drops. In this case you could choose to measure across either the hoods or drops and enter the value into the HANDLE BAR WIDTH row.

For the setup details you can enter any value.

Once complete press Finish. Your bike measurements will be saved into the fit log, and the initial and final bike measurements will be included on the fit report.

# Measurement wand tips & tricks

Best practices and techniques for using the measurement wand effectively in Velogic Studio for accurate calibration and bike measurements.

The measurement wand is used by Velogic Studio to capture the location in space of key points on the bicycle frame.

![Measurement wand showing green background panel with four pink triangular markers and measurement tip for precise positioning](/files/pzJ98VYGNwAxfQyyEBiF)

The measurement wand is used in [calibration](/section-03-calibration-and-measurement/calibration) and [bike measurement](/section-03-calibration-and-measurement/taking-bike-measurements) processes. This article will help you understand how to get the best accuracy from the wand.

## How it works

To use the wand effectively, it's useful to know how the system uses the wand.

The Kinect camera looks for the colours of the green background and the pink triangles. Once it has located the 4 pink triangles (on a green background) it will "project" a line down the middle of those triangles to where it knows the point of the wand must be.

There is more complexity than this, but that's the basic idea.

## Tip 1: Let your Kinect camera warm up for 10 minutes before the session starts.

Studies have been carried out on the accuracy of the Kinect camera. One study shows that the Kinect attains maximum accuracy one hour after being powered on, but achieves very good accuracy after only 10 minutes.

## Tip 2: Hold the wand by the handle.

Don't obscure any part of the green face of the wand, e.g. by holding it by an edge.

## Tip 3: Hold the wand in the same orientation where possible.

If there are any manufacturing inconsistencies with your wand (or you're using a self-printed paper wand, e.g. while trialling), you can minimise the effect of these inconsistencies by holding the wand in the same orientation for all points. This isn't always possible, but for example when taking the tip of the saddle, you can hold the wand vertical rather than horizontal.

## Tip 4: Cover the face with your other hand until you're ready.

This will prevent the system from including any frames where the wand wasn't quite in the correct position yet.

## Tip 5: Try to make sure the "low midline point" is actually low.

"Low midline" is one of the points captured during calibration. Try to get that as low as possible - e.g on the bottom bottle boss rather than the top one.

## Tip 6: Comparison with manual measurement methods

If the bike frame isn't level with the ground, e.g. the rear wheel is on a trainer and the front wheel is on the ground, then the bike isn't level.

Velogic Studio allows for this via calibration - that's what the front and rear "pitch points" are for. But if you're using a spirit level to measure manually, your manual measurements are likely to have a higher reach and lower stack because of the tilt of the frame.

## Getting help with unusual measurements

If you've followed the tips above and are still getting measurements that don't seem right, you can upload your measurement data to our support team for analysis. See [Sharing measurement data](/section-01-getting-started/sharing-with-support#sharing-measurement-data-if-you-get-unusual-measurements-with-the-wand) for instructions.


# Velogic Studio bike measurements defined

Detailed definitions and measurement procedures for all bike geometry measurements collected by Velogic Studio, including traditional and XY metrics.

Our Velogic Studio system collects a detailed set of bike measurements that combine both traditional relationships and modern XY metrics.

![Velogic Studio interface displaying comprehensive bike measurement data including saddle height, setback, handlebar positions, and frame geometry](/files/KkxF2xjPKdvrbWTp9tFr)

The definitions for these measurements are listed below.

## Saddle height

Measured from the centre of the Bottom Bracket to the top of the saddle. If the velogicfit Saddle Jig is used the saddle measurement point is where it is 80mm wide. Without the Jig the standard measurement point is 140mm back from the saddle nose for a road saddle or 100mm for a ISM Adamo style noseless saddle.

![Diagram showing saddle height measurement from center of bottom bracket to top of saddle using measurement wand and saddle jig](/files/ggPkmlMWlXVg53A9mHe3)

## Saddle Setback

The horizontal distance between the centre of the Bottom Bracket and the tip of the saddle. Can be measured using a Plumb Bob, Level or by finding any vertical straight edge such as the corner of a wall. Alternately you can place the rear wheel against a wall, measure from the wall to the centre of the Bottom Bracket then from the wall to the nose of the Saddle.

![Illustration of saddle setback measurement showing horizontal distance from bottom bracket center to saddle tip using plumb bob method](/files/nLzqhWXYRMwqdbCjzpVU)

## Handlebar X

The horizontal distance from the centre of the Bottom Bracket to the centre of the Handlebar clamp. This can be measured using an XY tool, or a vertical straight edge or you can place the rear wheel against a wall, measure from the wall to the centre of the Bottom Bracket then from the wall to the centre of the Handlebar clamp.

![Handlebar X coordinate measurement showing horizontal distance from bottom bracket center to handlebar clamp center](/files/M4GpShVgaJLghR9EhtrS)

## Handlebar Y

The vertical distance from the centre of the Bottom Bracket to the centre of the Handlebar clamp. This can be measured using an XY tool, after ensuring the bike is truly vertical measure from the floor to the centre of the Bottom Bracket then from the floor to the centre of the Handlebar clamp.

![Handlebar Y coordinate measurement showing vertical distance from bottom bracket center to handlebar clamp center](/files/0QQja0Oc1ZzklsGgXwgt)

## Handlebar Width - Road

The centre to centre distance of the Drops. Easily measured with a tape from the inside of one side of the bar to the outside of the other. Note that some bars flare from the Hoods to the Drops so you may need to note both Hoods and Drops width.

![Road bike handlebar width measurement showing center-to-center distance of the drop section of handlebars](/files/ME7G0ZYl6y7uc2L7D9Vl)

## Handlebar Width - MTB

End to end of the bar, easily measured with a tape.

![Mountain bike handlebar width measurement showing end-to-end distance across straight mountain bike handlebars](/files/kNDRpqsi0eVoAY2vL4ht)

## Handlebar Width - Tri/TT

Centre to centre of the basebar grips. Easily measured with a tape from the inside of one side of the bar to the outside of the other.

## Hood X

The horizontal distance from the centre of the Bottom Bracket to the upturn of the Brake Hoods. This can be measured using an XY tool, or a vertical straight edge or you can place the rear wheel against a wall, measure from the wall to the centre of the Bottom Bracket then from the wall to the upturn of the Brake Hoods.

![Hood X coordinate measurement showing horizontal distance from bottom bracket center to brake hood upturn point](/files/Y9v94dk4hgvVfow9eLWA)

## Hood Y

The vertical distance from the centre of the Bottom Bracket to the upturn of the Brake Hoods. This can be measured using an XY tool, after ensuring the bike is truly vertical measure from the floor to the centre of the Bottom Bracket then from the floor to the upturn of the Brake Hoods.

![Hood Y coordinate measurement showing vertical distance from bottom bracket center to brake hood upturn point](/files/DLKTWRIQuhQhEnwHjAeo)

## Bar Drop

The vertical distance between the top of the Saddle and the top of the Bars (beside the Stem). Can be measured using a level or by measuring from the ground to the top of the Saddle and ground to top of the Bars. Note that if your Bar Drop is a negative number it indicates that the Bars are higher than the Saddle

![Bar drop measurement showing vertical distance between top of saddle and top of handlebars beside stem](/files/4511jhLCJZ2kyxECyZ6O)

## Saddle to bars

The direct distance from the nose of the Saddle to the top of the Bars at the centre of the Stem clamp

![Saddle to bars measurement showing direct distance from saddle nose to top of handlebars at stem clamp center](/files/IYTuDYOatMpimVUfXZXD)

## Saddle to drops

The direct distance from the nose of the Saddle to the end of the Bar drops.

![Saddle to drops measurement showing direct distance from saddle nose to end of handlebar drop section](/files/D9maWbGuvyKrbKtrd2wl)

## Frame X

Also known as Reach (this is the number you will see in most geometry charts). The horizontal distance from the centre of the Bottom Bracket to the centre of the top of the Headtube. This can be measured using an XY tool or a vertical straight edge or you can place the rear wheel against a wall, measure from the wall to the centre of the Bottom Bracket then from the wall to the centre of the top of the Headtube.

![Frame X (Reach) measurement showing horizontal distance from bottom bracket center to top of head tube center](/files/SZ6Yonh5kGWbjIImIrC4)

## Frame Y

Also known as Stack (this is the number you will see in most geometry charts). The vertical distance from the centre of the Bottom Bracket to the centre of the top of the Headtube. This can be measured using an XY tool or, after ensuring the bike is truly vertical, measure from the floor to the centre of the Bottom Bracket then from the floor to the centre of the top of the Headtube.

![Frame Y (Stack) measurement showing vertical distance from bottom bracket center to top of head tube center](/files/s5WY2FeCjFzLW1BKEtS8)

## Seatpost X

The horizontal distance from the centre of the Bottom Bracket to the front of the Saddle Rail clamp. This can be measured using a vertical straight edge or you can place the rear wheel against a wall, measure from the wall to the centre of the Bottom Bracket then from the wall to the front of the Saddle Rail clamp.

![Seatpost X coordinate measurement showing horizontal distance from bottom bracket center to saddle rail clamp front](/files/R1wXr1FayE4eoj6lH7fL)

## Seatpost Y

The vertical distance from the centre of the Bottom Bracket to the front of the Saddle Rail clamp. This can be measured using an XY tool or, after ensuring the bike is truly vertical, measure from the floor to the centre of the Bottom Bracket then from the floor to the front of the Saddle Rail clamp.

# BikeFinder Integration

How to use Velogic Studio Pro's BikeFinder integration to suggest target frames and stem configurations for optimal bike fit positioning.

> **Note:** This feature is only available with Velogic Studio Pro. It's not available for Velogic Studio Essentials.

## Rationale

Helping your client select and/or configure a suitable new bike is often considered part of a bike fit. Velogic Studio's bikefinder integration helps you make that a seamless part of your bikefit offering.

### If they have a particular bike in mind: use "Target Frames"

Bike fit clients often arrive at a bike fit with either:

* an existing bike, wanting to be fitted to that bike (which can be awkward if it's not the right bike for them)
* or pre-purchase, but with a particular bike in mind, and wanting to know the right size of that model.

After conducting the fit, many fitters will then work out options for their client:

* If they had an existing bike, but were fitted to a different barXY position: you need to find a stem/spacer configuration to achieve that position
* If they had a particular bike in mind, you need to suggest the best size AND then find a stem/spacer configuration to achieve their target XY.

Velogic Studio can help by suggesting a stem/spacer combination, and optionally a frame size, automatically during the fit. Whenever you measure the frame (either manually, or with our measurement wand), and the measurements include BarX and BarY, Velogic Studio will make a suggestion.

Read more in the "Choosing target frame(s)" section below.

### If they want bike suggestions: use "Online Search"

If your client isn't already set on a particular model, you can send them home with a report showcasing some options that are likely to work for them.

Read more in the "Online search" section below.

## Choosing target frame(s)

At the beginning of a fit, or at any time during the fit, you can add a target frame. In Step 1: Configuration, just click on "Add target frame":

![Velogic Studio Step 1 Configuration interface with 'Add target frame' button in the Target Frames section](/files/7czhmf3yWvTNoGZXFA4T)

> **Note:** If you don't see the Target Frames area, you may not be on the Pro level of Velogic Studio, or you may need to enable the BikeFinder plugin (Settings -> Plugins)

You'll see a Frame Search popup, where you enter a search term:

![Frame Search popup window with search input field for entering bike brand, model, and year information](/files/Zkgo13jL0KhYVU6LCRii)

The search term is free-form text, so you can include brand, model and/or year. A maximum of 30 results will be returned; if the frame you're looking for isn't in the resultset, but you have lots of results, you may need to be more specific.

If you can't find a frame that you believe should be in the database, please contact us (<frames@velogicfit.com>) to request it be added.

Once you can see the frame you're looking for, click on it, and you'll see it appear in the right-hand side of the search window:

![Frame search results showing selected bike frame with size options and 'Add target frame' button](/files/RYGoFMlauzPcOVlHMICf)

You have the opportunity to select a particular frame size (e.g. if your client already has the bike), or leave the size as "Any" for Velogic Studio to suggest a frame size.

Click "Add target frame", and the search popup will close and the frame will be added to the Target Frames area:

![Target Frames section displaying added bike frame with configuration options for BarXY Tolerance and Saddle Protrusion](/files/RKNNabAqtRz172CD5I3m)

> **Note:** You can have multiple target frames for the same frame, with different sizes. E.g. if you client has a size 'M', you can add one target frame for that size, and a second target frame for the same model but "Any" size. You can then compare the best stem/sizer configuration for their size, and also the suggested best size.

Once you've added one or more target frames, you'll see options for BarXY Tolerance and Saddle Protrusion at the top of the Target Frames area. They are both optional, but if you switch them on, you can add parameters used to generate the recommendations:

![Target frame configuration showing BarXY Tolerance and Saddle Protrusion settings for precise fit recommendations](/files/LbfLCIguiqe33JcWkHcA)

* If you specify a BarXY Tolerance (mm), Velogic Studio will never suggest a stem/spacer configuration which is further than the specified distance from the target bar XY.
* If you specify a Saddle Protrusion (%), and you then measure saddle height, Velogic Studio will also check that the saddle post + saddle "protrude" at least the specified percentage of total saddle height above the seat tube. This is to prevent a situation where a shorter rider in an aggressive position is suggested a large frame (to achieve the desired reach), BUT the saddle would be slammed down onto the frame (or be forced higher than the ideal height by the seat tube). For more information, see "What is Saddle Protrusion" in the FAQ section below.

## Getting suggestions for target frames during measurement

When you have added some target frames, and you measure the frame with the measurement wand (or enter manual measurements), you'll see suggested frame sizes and/or stem/spacer combinations to achieve that barXY (and optionally saddle height):

![BikeFinder suggestions displaying recommended frame sizes and stem configurations with accuracy metrics for each target frame](/files/0OrlwPJkDZt5Jp4UXdQx)

For each target frame you added in step 1, you'll see one suggestion, containing:

* The brand, model and year of the target frame
* The target size you selected
* A suggested size (only if you selected "Any" for target size)
* A suggested stem configuration, e.g. "120mm +8°, 15mm sp."
  * **120mm** is the stem length
  * **+8°** means an 8° stem, angled upwards (if the sign was negative, e.g. -8°, that would mean that the stem is angled downwards)
  * **15mm sp.** means 15mm of spacing from the top of the head tube to the bottom of the stem.

> **Note:** The spacers number is from the top of the head tube. You need to measure and subtract the height of the cups and headset cap/top race to determine the physical spacers to add.

* Information on how close the suggestion is to your target measurement:
  * Bar X and Bar Y shows how many millimeters the suggestion exceeded the target (or fell short if negative)
  * Saddle shows the percentage of saddle protrusion (see FAQ)

When you click Finish, the measurements are added to the Fit Log.

## Viewing frame suggestions in the fit log

When you view the fit log, you'll see a "Target Frames" section inside the "Bike metric" section, with one row per target frame.

Each target frame row will show a suggestion for each measurement column, so you can see the suggestion for different positions that you've measured during the fit.

![Fit log Target Frames section showing frame suggestions across different measurement positions with stem and spacer recommendations](/files/0GD2DSoGeOLDU2e2cVbn)

If Velogic Studio cannot make a suggestion (because it couldn't find a frame size and stem/spacer combination within the specified tolerance of the target bar XY), it will show "No suggestion". If you don't specify a bar XY tolerance, then Velogic Studio will always make a suggestion, even if it's ridiculously large (or small) for the target barXY position. In that case, you can read the BarX and Bar Y errors, and saddle protrusion, from the bottom row of text to decide whether it's acceptable.

## Online Search

You can use the Online Search feature of the BikeFinder module when taking measurements or reviewing an existing measurement.

![Online Search interface displaying multiple bike frame options with compatibility ratings for measured rider position](/files/PbutiIGE7dZ5KPmQSj04)

## FAQ

### Q. Can I use the Target Frames feature offline?

A. No. This feature connects to the Velogic online frame database, so the feature will not work if you are offline.

However, you can conduct a fit offline, and then later when you are online again, you can add target frames to retrieve suggestions for the fit.

### Q. What if I don't like the suggestion for a target frame?

A. Please get in touch and explain the details of the recommendation you got, and why it wasn't what you expected. Our suggestion engine is constantly improving to give the best results in a range of circumstances.

### Q. What is saddle protrusion?

A. The saddle height (distance from the bottom bearing to the top of the saddle) is achieved via 3 components or stages, from the bottom up:

* the seat tube (from the bottom bracket to the top of the seat tube)
* then the visible part of the seatpost
* and then the saddle itself.

Saddle Protrusion is simply the percentage of the saddle height that comes from the visible part of the seatpost and the saddle. It's a measure of how much the seatpost "sticks out" of the seat tube.

Velogic Studio will show the saddle protrusion percentage, if you have measured a saddle height and if we have SeatTubeCT data available for the selected frame (which we mostly do).


# Aero basics

Fundamental principles of aerodynamics in cycling, including drag force components and their impact on performance optimization.

At higher cycling speeds, a significant portion of a rider's power is expended in overcoming aerodynamic drag (Martin et al. 1998).

As speed increases, wind resistance grows exponentially, meaning a small increase in speed requires disproportionately more power to maintain. Research shows that high speeds, up to 80-90% of a cyclist's power output is dedicated to overcoming air resistance (Bassett et al., 1999; Faria, 2005). This is due to the relationship between velocity and drag, where the power required to counter drag increases with the cube of the speed (Martin et al., 1998). As a result, reducing drag through body position, equipment, or clothing can have a substantial impact on cycling performance, especially in time trials or road races where maintaining high speeds is crucial (Faria et al., 2005).

The aerodynamic drag force is defined as the resistance experienced by an object moving through a fluid, such as air. It is mainly caused by pressure differences between the object's front and rear surfaces and the friction of the air against its surface. The formula for aerodynamic drag force is:

![Aerodynamic drag force formula showing the relationship between drag force and air density, velocity squared, frontal area, and coefficient of drag](/files/o4GIXRIzzxSOGmdg8GXf)

... which tells us that aerodynamic drag force is relative to 4 factors:

* Air density (rho)
* The velocity (actually, the square of the velocity) of the air relative to the rider
* The frontal area (A)
* The Coefficient of drag (Cd). This quantifies the drag or resistance of an object in a fluid environment, such as air or water. It represents how streamlined an object is, or how effectively it cuts through the fluid. The value of Cd is dependent on the shape, surface roughness, and flow conditions around the object. Lower values indicate more aerodynamic objects, while higher values reflect more resistance.

In cycling, we are interested in minimising the aerodynamic drag force, so that more of the power produced by the athlete goes to increasing velocity. Which of those factors can we control?

* We can't control the air density
* It would be counterproductive to reduce velocity just to reduce aerodynamic drag force, since velocity is what we're trying to maximise overall
* We can control the Coefficient of drag, by changing the shape (position) and surface roughness of the rider and bicycle
* We can control the Frontal Area, by changing the position of the rider.

Therefore, much of the effort in aerodynamic optimisation goes into the Cd and A factors.

# What you can (and can't) do with Aero in Velogic Studio

Understanding the capabilities and limitations of Velogic Studio's Aero module for frontal area measurement and aerodynamic analysis.

> **Warning:** "All models are wrong, but some are useful". Please do not rely on the analysis provided by the Aero module without verifying via other means, e.g a wind tunnel or real-world measurement.

This page outlines the limitations of Velogic Studio's Aero module. Please read the [Aero Basics](/section-04-aero/aero-basics) page if you're not already familiar with aerodynamics.

## Cd, A, and CdA - what is Velogic Studio actually measuring?

In general, it's not possible to directly measure Cd, (Coefficient of Drag). The closest we can come is to measure Cd x A in a wind tunnel. Going [back to our equation for Aerodynamic Drag Force](/section-04-aero/aero-basics):

![Drag force equation highlighting the measurement of CdA (coefficient of drag times frontal area) in wind tunnel testing](/files/eQBkrdVGkfBERvGW6UJD)

In a wind tunnel, the density of the air can be measured. Then, velocity of the wind can be varied, and the drag force measured. Those values can be plugged into this equation to give Cd x A, which is referred to as CdA. The goal of a wind tunnel session is often to minimise CdA, in the hope that this will lead to better performance in the real world.

By contrast, Velogic Studio uses a time-of-flight "depth sensing" camera to measure A (frontal area). Velogic will also estimate the Cd, using information from the lateral camera. Velogic Studio makes the assumption that the largest contributor to the Cd is the torso angle; changes due to e.g. different clothing won't be detected.

## Valid uses of Aero in Velogic Studio

You can use the frontal analysis module of Velogic Studio to:

* Establish a baseline Frontal Area number for a rider
* Make small adjustments to the rider's position, and see the effect on Frontal Area
* Use basic calculations to illustrate the effect of a change in position:
  * At the start of the fit session, you can specify a baseline course outcome (distance and time)
  * For the initial baseline position, you can supply a Cd number, either from your own experience, or estimated from lookup tables, or measured on a test course or wind tunnel
  * Velogic Studio will then calculate, for each different position (with a different measured Frontal Area:
    * The change in power required to achieve the same course outcome at different positions.
    * Or, the change in course outcome which could be achieved if the same power is maintained with each different position.
* Measure the rider's Frontal Area at regular intervals over a longer test period (e.g. every 5 minutes over a 1 hour period) to determine how well the rider can hold a desired position over time.
* Measure changes in a rider's Frontal Area across larger spans of time, e.g. a season.

## Limitations and invalid uses of Aero in Velogic Studio

* The camera that's used by Velogic Studio can't actually see all of the surface of the rider that's making contact with the air. For example, if the rider's head is tucked down, Velogic Studio may not be able to see the top of the rider's back, even though this area should be part of the frontal area. This means that although it can detect changes in frontal area, it isn't accurate as an absolute measure.
* The frontal camera obviously can't see behind the rider's head; and yet we know that teardrop helmets make a difference to CdA. This is a good example of how CdA can be affected by Cd or A; Velogic Studio can only measure A.
* The time-of-flight camera can't "see" very dark blacks, especially when they are on an angle to the camera. For this reason, Aero **won't pickup up a black helmet.** We recommend you use a light-colored fabric helmet cover in this case.
* Similarly, the time-of-flight camera might struggle to see some parts of the rider if the rider has very dark clothing on.
* The course outcome calculation makes very many assumptions, so should only be used for illustrative purposes. It doesn't account for course terrain, variations in speed, variations in air density, cross winds, changes in rolling resistance and other factors.
* It's possible that a position change which results in a higher A could actually result in a lower CdA, e.g. if the new position has a significantly better Cd. For this reason, we only recommend the use of Velogic Studio to investigate relatively small changes in A, which are less likely to affect the Cd.

## Where does Velogic Studio fit into the landscape of aero assessment tools?

We think of Velogic Studio as a relatively low-cost way to begin an Aero analysis. Different positions can be quickly tried out in the studio, and promising positions selected for further analysis in the wind tunnel or on the track.


# How to use Aero in Velogic Studio

Complete guide to setting up and using the Aero module with frontal cameras for aerodynamic analysis

## You will need:

* An Orbbec Femto Mega camera, to be placed in the front of the rider. This might be your 3rd Femto Mega camera if you already have 2 for bilateral capture.
* A network cable connecting the camera to the PoE Network Switch (assuming you already have a network switch for your other cameras.)
* A sync adaptor and second network cable to connect the camera to the Orbbec Sync Hub (assuming you have a sync hub for your other 2 cameras)
* Tripod or other camera mounting option
* A subscription to Velogic Studio Pro (the Aero module is a Pro-only feature)
* A PC meeting our [System Requirements](/section-01-getting-started/pc-system-requirements#System_requirements_Velogic_Studio_Pro_multiple_depth_cameras).

## Positioning the camera

* **Place the camera mounted vertically** (so rotated 90degrees from the "natural" orientation; the camera sensors are wider than they are high, so by rotating, we can use the longest axis to match the height of the rider)
* **Optimal distance for the camera is 1200mm** (measured from the front of the camera to the leading surface of basebar for Tri, TT and road). It's OK to go further back, but not too much closer than that.
* **Optimal height of the camera is at the same height as the base bar or handlebars.**

## Installing Velogic software on the camera

If you are using a brand-new Orbbec Femto Mega camera, you will need to [book an installation session](/section-01-getting-started/pro-installation-session) so that our support team can install the "Velogic FrameBlaster" software onto the camera.

If you're repurposing a camera which had already been used as a lateral camera with Velogic Studio, it will already have the FrameBlaster software, so you won't need to book an installation session.

## Configuring the camera in Velogic Studio's Step 1

In Step 1 of Velogic Studio, you can set the placement of the new camera to "Frontal", and choose the orientation that matches how you have the camera installed:

![Velogic Studio Step 1 camera configuration showing frontal camera placement setting and orientation options for aero analysis](/files/kOQcpOzkNh7z992p6heb)

You should then see the live view change, and split into 3 different views. You need to adjust the selection rectangles on each of the 3 views to correctly capture the rider with as little background as possible:

![Three-panel camera view setup showing Color view, Wind view, and Depth view with selection rectangles for capturing rider positioning](/files/HW3ScvU80ppMfSWJscGf)

* **"Color view"** is the view from the color sensor in the Femto Mega camera. You should ensure that this rectangle is positioned to capture the rider, with some margin.
* **"Wind view"** is the view from the depth sensor in the Femto Mega. It has been "flattened" so that objects further away from the camera don't look smaller than objects closer to the camera, so it may look strange. This is the view that's actually used to generate the Frontal Area metric, so it's important that you correctly position the selection rectangle to cover the rider, but exclude things like the platform that the bike is sitting on. Note that this is a messy and imperfect-looking view, because Velogic Studio's algorithm is compensating for parts of the rider it can't actually see (e.g. the rider's chest obscured by their hands). Our algorithm accounts for this, and the overall Frontal Area metric that you see is a statistical combination from many frames.
* **"Depth view"** is also from the depth camera, but as if viewed from the side of the rider. You can adjust this rectangle to control the "front" and "back" cutoff distances, to ensure that you capture all of the bike+rider, and nothing else (such as a platform or rear trainer). Make sure that the rectangle is positioned far enough backwards to get the rider's whole ankle at its rearmost point, i.e. halfway up the recovery phase of the stroke.

## Adding Aero Baseline Details in Step 1

When you have an Aero camera active, you will see an "Aero Baseline Details" panel on the right-hand side of step 1:

![Aero Baseline Details panel showing course distance and baseline time configuration for aerodynamic performance calculations](/files/HmWEGM3qcpj8QsdGAJHI)

* Course Distance and Baseline Time give Velogic Studio an idea of how far and how fast your rider is travelling. This is used when estimating the effects of changing position, see "Aero MotionMetriq's" below.

## Aero liveview and metrics in Step 2

Once you've moved to Step 2, you'll see a Liveview of the frontal camera:

![Step 2 frontal camera live view displaying metric blocks with real-time Cd, A, and CdA measurements at bottom of interface](/files/PzckcjiiMHoiQYJl16L0)

The numbers at the bottom of the image are called "Metric blocks", and they're updated live.

In the left-hand bottom corner, you can see metrics related to Aero:

* Cd (coefficient of drag, which you have entered)
* A (frontal area, which Velogic Studio has measured)
* CdA (Cd x A, the product of the two terms, which should correlate to what you would measure in a wind tunnel)

You can also click on the "Wind" button at the top to see the Wind View:

![Wind View visualization showing color-coded representation of rider surface angles relative to wind direction for aerodynamic analysis](/files/hDUcI5eKVErarznQO14U)

The Wind View is Velogic Studio's representation of "How the wind sees the rider". It's color-coded: red areas are flat on to the wind, and green areas are sloping away from the wind. This isn't a CFD analysis; it's solely looking a the slopes of each region of the surface facing the wind.

### Aero MotionMetriq's

The following additional MotionMetriq's are available on the right-hand side of step 2 when you're using Aero:

![Aero MotionMetriqs panel showing Frontal Area group and Course Outcomes group with detailed aerodynamic performance metrics](/files/EounJrRK7VAwoZkaIVP9)

**Frontal Area group:**

* **Frontal Area** is Velogic Studio's measurement of the frontal area of the rider + bike, in m²
* **Cd** is Velogic Studio's estimate of the Coefficient of Drag of the rider. The estimation method is proprietary, but is based on the torso angle and the position of the rider. If you aren't using a lateral camera, this number will be blank.
* **CdA** is simply Coefficient of Drag x Frontal Area. This is what a wind tunnel measures.

**Course Outcomes group** uses the current CdA, plus the data entered in Step 1 (Course Distance and Baseline Time):

* **Aero Drag Power** is an estimate of the power (watts) produced by the rider that is going solely towards overcoming Aero drag force. This is calculated from the current CdA, the average speed (Course Distance / Baseline Time) and a number of assumptions. It's not intended to be accurate (and there are too many assumptions for it to be accurate) but it will give a good indication of the difference in power required in different positions through the fit.
* **Course Time (mins)** is the time it would take to complete the course distance entered in step 1 at the current CdA. For the Initial capture, this will be set to the Course Time set in Step 1, assuming that the initial position is the baseline position. For subsequent captures, this will be adjusted based on the difference in CdA; if the CdA goes down, the course time should also go down. Again, this won't be accurate because of the number of assumptions involved, but when compared against other captures it gives a good indication of how different Aero positions impact speed and therefore course outcomes.


# Deep Dive: Frontal Progression

Advanced feature for visualizing frontal area changes throughout a fit session, showing position improvements for customer reporting.

Frontal Progression helps you show your customer how their frontal area has changed during the fit.

It shows a series of images, side by side, showing how the frontal area of each capture compares with the final capture.

## How to invoke Frontal Progression

Before you invoke the frontal progression, you should check that the Final Position is checked on the capture that you consider to be the final position resulting from the fit. This Final Position will be used as the comparison target for the images in the frontal progression:

![Velogic Studio interface showing Final Position checkbox selection for establishing frontal progression comparison baseline](/files/SZa3lcPin7NZ0yCwCkLw)

In step 2, on the fit log at the bottom of the screen, there's a "DEEP DIVE" button on the left; click that and you'll see FRONTAL PROGRESSION as an option:

![Deep Dive menu in Step 2 fit log with Frontal Progression option highlighted for accessing progression analysis](/files/zEsqMqzSSVeHBKOZZQkH)

## Frontal Progression window

The Frontal Progression has all of the captures in this fit session, arranged right-to-left along the screen.

Each capture is color-coded to show the parts of the rider that are different to the final capture:

* **Red color** means frontal area present in the current capture, but not in the final capture. You can think of this as "was worse" if thinking purely in terms of lower frontal area = better
* **Green color** means frontal area present in the final capture, but not in this one. You can think of this as "was better" in that capture.

![Frontal Progression window showing multiple captures arranged chronologically with color-coded frontal area differences](/files/D7yKfbA29NchsKo1G7bE)

## Adjusting Frontal Progression entries

Often it's necessary to fine-tune what you see in the Frontal Progression window.

This can be done by clicking "EDIT" on the top-right of any individual progression entry, and then doing one of the following:

### To exclude a capture from Frontal Progression

... click the EXCLUDE link at the top, and then click DONE. It will disappear from the Frontal Progression window.

To bring it back, click on the "Show excluded" option at the bottom of the screen, then click EDIT on the entry and click INCLUDE then DONE.

### To find a better frame for that capture

Velogic Studio will automatically try to find the frame best representing right-foot-down, for comparison purposes; but if it hasn't done a good job, you can use the Next/Previous frame buttons to pick a better frame:

![Frontal progression edit controls showing Next/Previous frame buttons for selecting optimal frame for comparison analysis](/files/xubWJ2JZtQnqK0hFdcuZ)

(note that these are only visible after you've clicked EDIT for that entry, and once you've found the best frame, you should click DONE at the top-right.)

### To reposition the image

Ideally the camera doesn't move during the fit; but sometimes it may move, and the comparison can look invalid because the final capture is just in a different place to the current capture, giving large green areas and large red areas.

To overcome this, you can adjust the blue rectangle around the rider image, and the red and green areas will be recalculated automatically.

When finished, click DONE to lock in the change.

## Frontal Progression on the report

In the reporting step (Step 3), the report will contain a "Frontal Progression" section if this option is selected on the left-hand side

![Step 3 reporting interface with Frontal Progression option selected in left sidebar for including progression analysis in reports](/files/qKySLYSXy6pzocEFUwpB)

It will include multiple pages if necessary to show all of the different captures, and their colorisation to show the differences between each and the final:

![Generated report showing frontal progression across multiple captures with color-coded visualization of frontal area changes](/files/CQ34mTANZYbkyPW3ghij)

Note that any captures which were "Excluded" in the Frontal Progression window will be excluded from the report too.


# Sustainability Test

Learn how to use the auto-capture sustainability test function to evaluate how long riders can maintain positions

> **Info:** The Sustainability Test function was introduced with the Aero module of Velogic Studio, but doesn't require a frontal camera to run; you can use it just with lateral cameras too.

The Sustainability Test function is simply "auto-capture on a timer". Its intended use is to see how long a rider can hold a new position before something changes, usually due to fatigue.

To start a Sustainability Test, click the small arrow on the right-hand side of the Capture button on step 2, and then click "Sustainability Test":

![Capture button dropdown menu showing Sustainability Test option for automatic timed capture functionality](/files/z5ZajAA3lTMjcRVGLcAS)

This will open a small configuration window, where you can set how often you want a capture to be taken, and for over what period:

![Sustainability Test configuration window with settings for capture frequency and total test duration](/files/AnUd3prxioquTFQBZIEm)

When you click START, the Capture Area will change to show you information on the progress of the sustainability test:\
![Active Sustainability Test interface showing progress indicators and real-time capture countdown with cancel option](/files/vrz6OD05BTQ3UMC5dUBB)

You can cancel at any time. When each capture is taken, it will be automatically named with the time of the capture.

When the test is complete, you can consider using [Spark Lines in the fit log](/section-02-using-velogic-studio/spark-lines) to get a quick idea of if/when the important parameters changed during the fit.


# Using frame comparison

Learn how to use Velogic's free Frame Comparison tool to compare bike geometry, specifications, and calculate Bar XY positions

The free velogicfit [Frame Comparison tool](https://www.velogicfit.com/frame-comparison) offers a quick, fully-user-controlled way of comparing two or more frames side by side.

You'll find frame geometry, images (if available) and frame specifications. If you've got a target Bar X & Y (e.g. from a pre-purchase bike fit), you can also investigate the effect of different stem length/angle and spacer combinations making it easy to order the correct parts and set the bike up correctly first time.

If you are not familiar with X & Y terminology for bikes please read [our explanation](/general/bar-xy-coordinates).

## Getting started

The first step is to choose the bikes to compare. Simply type the make and/or model of the bike in the search bar:

![Frame Comparison search interface with search bar for entering bike make and model to find frames for comparison](/files/CgyGIs2WWiR2AFzxIX4U)

... and select from the list. Repeat for the second frame, and as many as you like (within reason!)

> **Note:** If the model you're looking for is not in our list, please drop us an email at <frames@velogicfit.com>. If you can find a link to the geometry page for the model you're requesting, that will help us add the model faster.

Once you have selected the frames and chosen a frame size, you should see frame geometry for each:

![Frame Comparison results showing side-by-side geometry data for multiple selected bike frames with size specifications](/files/K4dxfno2FjcifRGDMe8N)

At the bottom of the page you can also find Frame Specifications:

![Frame specifications section displaying detailed technical data and calculated measures information for compared bike frames](/files/bV2JCRbp2eK4rYn5sj2u)

The Calculated Measures entry lets you know which values we've had to work out. If we've had to make assumptions for the frame geometry the figures may be a few millimetres off – especially if the Frame Reach and Stack were not provided by the manufacturer. If a frame you're interested in is marked as having a calculated Reach and Stack, feel free to put pressure on the Manufacturer to provide that information and thus facilitate accurate position calculations.

## Specifying the stem

After choosing frame(s), the next step is to specify what sort of stem you're using on the frame. This allows Frame Comparison to calculate Bar XY for that combination of frame and stem. See our [guide to using BarXY coordinates](/general/bar-xy-coordinates) if you're not sure on the definition of Bar XY.

You can change the stem length, angle and/or headset to have Frame Comparison calculate the BarX and Y for you.

![Stem configuration interface showing length, angle, and headset spacer settings for calculating Bar XY coordinates](/files/By0YnDnuEKJHs0yR44a6)

The Headset height/spacers value includes the height of the headset top cover (for integrated headsets). The possible heights range from 3mm (the lowest headset cover we know of) to 45mm (the maximum recommended for most forks). If you wish to perform the calculation for a frame that utilises an external headset you will need to know the stack of the chosen headset (usually around 30mm) and use that as a minimum value.

## Hoods Position

Bar XY gets you from the Bottom Bearing to the handlebar clamp. But, hopefully you're not steering by holding on to the handlebar clamp!

With Frame Comparison, you can choose a handlebar make & model (and optionally width), and it will calculates a Hood position for you, for a more accurate measure of where your hands will be positioned on the bike. Note that the Hoods position will not be completely accurate - because our models don't allow for every variation in bar geometry, and because you may be angling the bar.\
![Hoods position calculator showing handlebar selection and width options for accurate hand position calculations on bike setup](/files/gf3OT1UkZTdi0uiTXrs4)

For more information on this feature, see: [Frame Comparison - Bar Curve X and Bar Top Y for Road Bikes](/velogic-web-tools/frame-comparison-bar-curve)

## Share your comparison with the world

If you're looking for some input on your frame selection, why not share the results of your Frame Comparison on one of the many cycling forums? Or maybe you're a fit pro & want to respond to someone's question about which frame they should be buying. After selecting your frame, stem & bar options in Frame Comparison, just copy the URL from your browser's address bar. It contains all of the selections you've made on the Frame Comparison page, so anyone clicking the link will arrive at the same details as you.

## In summary

We hope you enjoy using Frame Comparison tool. If you have any questions about it, please get in touch with us using the chat system (link is at the bottom right of our site.)

If we don't have the information for a brand that you want to use in the system it's probably because we found it difficult to source that data. It would be helpful if you could contact the Manufacturer as well as our team to express your interest in having the data in our system.

Please note that the images and information provided by the site are based on what we have sourced from the Manufacturers website. We have taken all care in collecting the data but we take no responsibility for incorrect data that has been provided by the Manufacturer, or images that do not reflect the configuration of a particular model.

# Frame Comparison - Bar Curve X and Bar Top Y for Road Bikes

Enhanced Frame Comparison metrics for precise position matching across different handlebar designs and stem combinations.

In order to enhance the usefulness of our [Frame Comparison](https://app.velogicfit.com/frame-comparison) tool we've added additional metrics that aid in precisely matching positions.

These metrics are Bar Curve X and Bar Top Y.

![Bike geometry diagram showing Bar Curve X and Bar Top Y measurements relative to handlebar design and bottom bracket position](/files/v6qa3mgPgrYZrgZIrtTD)

To calculate these metrics for road bikes we add the handlebar reach to the Handlebar X value. And the stack of the top of the handlebar to the Handlebar Y value.

Zooming in on the bars:

![Detailed handlebar measurement diagram showing reach point to center of tube and stack point to highest section near hoods](/files/Bs3wBrxsAavovfR0Mon0)

It is important to note that the reach point on the bar curve is to the centre of the tube. And the stack point is to the highest point on the outer section of the bars near the hoods.

We've created these metrics for several reasons:

* To account for variations in bar design
* To make it easier for fitters to match positions

## Variations in bar design

While there have long been variations on the classic Maes bar, we are starting to see a lot more variety in shapes, partially thanks to the rise in popularity of Gravel riding.

The Specialized Hover bar and BP4 bar are examples of opposite ends of the spectrum:

![Specialized Hover handlebar profile showing 15mm rise design characteristic for gravel and road bike applications](/files/Y88bfbGm1rrEFrOxs0jw)

![BP4 handlebar profile showing 54mm drop design creating significant difference compared to rise handlebar designs](/files/aZYtBlyoLhtwwDewRqWg)

The Specialized rises by 15mm while the BP4 drops by 54mm. This leads to a significant difference in the height of the hoods, for the same Bar XY. Or a significant difference in Bar XY if you wish to maintain the hood position.

## Easier for fitters

It's extremely quick to compare different bar/stem combinations.

![Frame Comparison tool interface showing different handlebar and stem combinations with spacer stack calculations for position matching](/files/BypXpb7XnzdjbqUiSrpE)

In the example above you can see that changing the bars for a rise option offers the possibility to reduce the spacer stack under the stem.

![Side-by-side comparison showing how rise handlebars enable reduced spacer stack while maintaining equivalent hood position](/files/0vdtJ6pIji5ivTwLb8Am)

## Why did we choose these points?

Bar XY is easy to understand because you measure from one point (centre of the BB) to another (centre of handlebar) in two dimensions. But there isn't a reliable point to do this with on the bars.

Bar Top has the advantage of being easy to measure and not heavily affected by the inclination of the bars.

Bar Curve is also fairly easy to measure and can be calculated using information provided by most bar manufacturers.

The goal with these metrics is to define a useful approximation for the virtual intersection of the handlebar with the hoods. Going beyond the metrics we have defined would require knowing exact details of the handlebar bend and hood interface.

If you have any questions please [contact us](https://www.velogicfit.com/contact).
