Analyzing Backward

Analyze the clip backward when the reference feature grows larger or smaller (change Type to Roaming) or when it is off screen at the beginning of the clip.

Note: You cannot analyze backward if you need to change or snap the reference box.

To analyze backward:

1. Use the frame controls to go to the last frame of the clip.
2. Position the reference and tracker boxes.
3. On the Tracker panel, click the Analyze Backward button to start the analysis backward.
