The tracker lets you automatically animate Power Windows to follow moving objects in a scene. To open the tracker palette, click on the cross hair icon in the toolbar. You’ll see a playhead, along with options for analyzing the pan, tilt, zoom, rotation, and 3D perspective of the shot. With your Power Window still selected, choose the options that best match the camera’s movement, move the playhead to the beginning of the clip, and click the track forward button. The clip is analyzed and the Power Window will be automatically animated to follow the object in your shot! The tracker can also be used to stabilize images or to attach effects, such as a lens flare, to specific objects in a scene.
