204 Chapter 7 Tracking and Stabilization

5 Drag the tracker box to a high-contrast area— for example, the large window in the

middle of the image.

The tracker is composed of the track point (the center), the reference pattern (the inner

square), and the search region (the outer square). Here’s how it works: Shake analyzes

the reference pattern (the area of your image isolated within the inner square of the

tracking box), then in subsequent frames looks for that pattern within the search

region (the outer square of the tracking box). When a match is found, Shake records a

track point (keyframe) at that coordinate.

6 Go to frame 1.

7 Click the Track Forward button in the Viewer shelf.

The 15 frames are tracked.

Note: You can also go to frame 15 and click the Track Backward button.

8 When the tracking is finished, activate applyTransform in the Parameters tab.
