Using stored tracking data

Once you've tracked a motion source layer, you can apply that layer's stored tracking data to other target layers. For example, you can apply the track to a light bulb's position and to the Lens Flare effect's control point.

To apply an existing track to a new target:

1. In the Tracker Controls palette, choose the tracked layer from the Motion Source pop-up menu.
2. Choose the track containing the tracking data you want from the Current Track pop-up menu.
3. Click Edit Target to open the Motion Target dialog box, which lists all the layers in the composition (except the motion source layer) as well as any point controls in effects applied to the motion source layer.
4. Select the layer or effect point control you want to animate, and click OK.
5. In the Tracker Controls palette, click the Apply button to apply the tracking data to the specified target. After Effects creates keyframes for the target layer or effect.
