Track perspective, scale, or rotational shifts

For images with significant change in size and angle, you can try a few different strategies.

Use a larger search area

  • In the Behaviors Inspector, click the track’s disclosure triangle to display the Search Size parameter, then increase the value.

Lower the Fail Tolerance value

  • In the Behaviors Inspector, click the track’s disclosure triangle to display the Fail Tolerance parameter, then decrease the value. With a lower Fail Tolerance value, the tracker is more likely to find a false match. With a higher value, the tracker is more strict in finding a match.

Begin the analysis at the clip’s midpoint

  • Move the playhead to midpoint frame of the clip, and click Analyze in the Behaviors Inspector to track forward to the end frame of the clip; then return to the midpoint frame, click the Reverse checkbox in the Behaviors Inspector, and click Analyze to track backward to the beginning of the clip.
