In the Tracker Controls palette, click the Analyze Forward button to begin tracking. If the track point strays off the targeted feature, click the Stop button, and then adjust the feature region. To correct drift, move the current-time indicator back a few frames and click Analyze Forward, or simply click Analyze Backward. Each time you analyze a frame, new tracker data replaces any existing tracker data.

When the tracked object becomes obscured so that the feature region can no longer track it, stop the analyzing process. If necessary, back up a few frames, and then move the feature and search regions to the new feature. Leave the attach point in the same location by pressing Alt (Windows) or Option (Mac OS) as you drag the area of the track point between the search and feature regions, or by dragging the edge of the feature region.

Use the Analyze controls to track the new feature.

When you’ve successfully tracked the new feature, make sure that the Tracker Controls palette lists the text layer as the Motion Target. If a different layer is listed, click Edit Target and choose the text layer from the Apply Motion To Layer menu. Click the Apply button to copy the tracker data to the text layer’s Position property as keyframes.
