Animating Shapes with Keyframes and Trackers
If necessary, you can animate shapes in one of two ways:
 Using keyframes: You can keyframe shapes. For more information on keyframing in
Color, see Chapter 14, “ Keyframing ,” on page 285
 Using a tracker: You can also use motion tracking to automatically animate a shape;
for example, to move to follow a feature that’s moving because the camera is
panning.
Once you create a tracker and analyze the shot (in the Tracking tab), you simply
select a shape from the Shapes List, and type the number of the tracker you want to
use in the Use Tracker field, and the shape is automatically animated. If Use Tracker is
set to 0, no trackers are applied. For more information, see the next section.
