Review the Track Summary |
The Track Summary panel graphically depicts track point quality across time. Use it to:
- review your overall work progress
- identify problem areas for a given track point
- delete frames from track data (see Delete frames from track data for details)
Track quality
Indicates the success of each point’s tracking over all tracked frames. Track quality is conveyed with the following colors:
- Green is good; all green is a perfect match between the original target and the subsequent frame
- Yellow is a warning
- Red is strong warning; all red means the tracker surpassed the Failure Threshold. Failure Threshold, on the Track Options control panel, controls the amount of difference the tracker permits between the original target and the subsequent frames.
- Blue lines are frames where you positioned the track box yourself
The quality is determined by calculating the average pixel difference between the starting target and each frame thereafter. When the feature changes shape or size, quality starts out green and diminishes as the point changes pattern.
Note
Use the color indicators as a guideline only. You must evaluate the Pointblast of the track point to be certain of the track point’s quality.

Per-point solvability
Indicates the point’s contribution to the scene’s solvability. To compute this indicator, Live evaluates the range of camera or object movement for all the frames where that point is tracked. The more angular measurements Live can obtain from the tracked point, the more the point contributes to the scene’s solvability, and so the more green it appears.
Navigation commands
Use the following Track Summary commands for navigation. They are under the View menu and the right-click pop-up menu.
Frame All
Changes the view to includes all points and all frames.
Jump To Start
Jumps to the first frame in the selected range.
Jump To End
Jumps to the last frame in the selected range.
Update During Drag
When this option is on, the other view panels update as you drag a selection of frames in the Track Summary. When it is off, the other view panels only update when you change frames.
