Load existing tracking data into a tracking behavior
If you’ve already recorded tracking data (via the Analyze Motion behavior, for example), you can load that data into a Match Move, Stabilize, or Unstabilize behavior in your project. Likewise, if your project contains animation (via keyframes or an applied behavior), you can load that animation data into a tracking behavior. When you do so, motion data from one object is applied to another object in your project.
In the Layers list, select an object to receive tracking or animation data.
Click the Add Behavior pop-up menu in the toolbar, choose Motion Tracking, then choose Match Move, Stabilize, or Unstabilize.
The new tracking behavior is added to the Layers list, under the selected object. If your project already contains tracking data or animation data (from an Analyze Motion behavior or from keyframed animation, for example), that data is automatically applied to the new behavior (when the In the new behavior is below the object with tracking or animation data in the Layers list). And the source of the data appears in the Behaviors Inspector and HUD (in the Source well).
If the Source well is empty, you must manually apply tracking or animation data, as described in the next step.
To manually apply tracking data to the new behavior, do one of the following:
In the Behaviors Inspector or HUD, click the Action pop-up menu (with a gear), then choose a new source for tracking data.
From the Layers list, drag a tracking behavior, footage with tracking data, or animated object to the Source well in the HUD or Behaviors Inspector.
In the Layers list drag a tracking behavior, footage with tracking data, or animated object onto the new tracking behavior in the Layers list.
Tracking or animation data is applied to the new behavior, and the source of that data (a video clip or animated object) appears in the Source well in the Behaviors Inspector or HUD.
Note: To clear a Source well, drag the item away from the well and release the mouse button.
