Working with the Tracker/Stabilizer Controls

The Tracker/Stabilizer is a panel added to the Layer window once you select the

Tracker/Stabilizer controls from the Layer window menu. The window displays the layer you

selected to track. To specify an area for tracking, set a feature region, a search region, and a

track point in the layer shown. The tracker tracks from the location of the current-time

indicator. If the current-time indicator is outside the visible range of a trimmed clip, it tracks

from the beginning to the end of the clip. If the current-time indicator is within the visible

range of a clip, it tracks from the current-time indicator to the end of the visible range.
