Adjusting the search region (Pro only)

The size and position of the search region depends on the movement of the feature you want to track. The search region must accommodate the movement of the feature, but only the frame-to-frame movement, not its movement throughout the shot. As After Effects locates the feature in a frame, both the feature and search regions move to the new location. Therefore, if the frame-to-frame movement is gradual, the search region needs to be only slightly larger than the feature region. If the feature changes position and direction quickly, the search region needs to be big enough to encompass the largest position and direction change in any pair of frames.
