Reviewing fit artifacts

Reviewing fit artifacts

As you carry out the fit, Velogic Studio records various "artifacts" for each capture. These include:
  1. Videos from the Kinect camera and/or any webcams you have at different positions around the rider.
  2. Images from those same cameras, and also from any visualizations generated by the system (e.g. knee track) 
  3. 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:

When you move the mouse over a thumbnail image for a particular capture, all of the "Visuals" and "Liveviews" on the screen change to show you the recorded images & videos from that capture. Also, the metrics change to show the metrics from that capture, and they have an asterisk (*) after them, to make it clear that these are historical (and not live) numbers.

Focusing on one particular metric

You can click on any metric in the Metrics area:

... it will be highlighted in green, and the fit log thumbnails will be overlaid with the value of that metric from each capture, together with an indicator showing the difference between that capture and the initial capture:

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

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:

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:

Numeric data (such as metrics) are shown with an indicator showing the change from the initial position.
Images and videos are shown as thumbnails, and you can move the mouse over a video to have it autoplay directly in the fit log grid.

If you click on a video or image thumbnail from the fit log grid, the Review window will open for that artifact.

Review window: Images

You can review an image either by clicking on an image in the Fit Log Grid, or by right-clicking on a Fit Log thumbnail and choosing "Review image <image name>".
The review window for images looks like this:

You can compare the current image with the same image from either the Initial or Final capture (or both) by checking the "Initial" and "Final" boxes in the column on the right:

 You can also choose the comparison mode:
  1. Side-by-side: show the two (or three) images beside each other
  2. Overlaid: show the two (or three) images partially transparent, on top of each other
  3. Crossfade: generate a short video showing one image fading out and the other fading in
  4. Morph: generate a short video of one image "morphing" (changing) into the other image.
Generally, morph comparison is best because it best helps the eye to follow the changes between the images:

For crossfade and morph comparisons, if there are 3 images selected, the comparison video will be generated between the earliest and the latest video (e.g. the Initial and the Final).
If you choose the crossfade or morph comparisons, you can save the resulting short video into your fit folder by clicking the Save button. You can also Share it directly to Instagram - see Sharing to Instagram documentation.

Review window: Videos

You can review an image either by clicking on a video in the Fit Log Grid, or by right-clicking on a Fit Log thumbnail and choosing "Review video <video name>".
Similar to the review window for images (see above), you can compare the video you selected with the same video from the Initial and/or Final captures:

You can use the play controls at the bottom of each image to play, stop, scrub, and frame-by-frame forwards or backwards.
You can also overlay the videos with a grid, to help compare movements within and between videos:
