Uses of motion tracking (Pro only)

Motion tracking has multiple uses:

• Combining elements filmed separately, such as adding video footage to the side of a city bus or a star to the end of a sweeping wand.
• Animating a still image to match the motion of action footage, such as making a cartoon bumblebee pursue a swaying flower.
• Adding effects that follow a moving element, such as applying a lens flare to a scene where the camera pans or making a ball glow.
• Stabilizing footage, such as smoothing the wobble of footage shot with a handheld camera.
• Applying effects or transform properties to a layer using tracking data in expressions, such as stretching a wire coil between two objects. (For more information about using expressions, see Understanding expressions.)

Note: If you're familiar with the principles of motion tracking, see Working with the Tracker Controls palette (Pro only). If you're familiar with motion tracking in After Effects, see Tracking motion to apply to other footage or images (Pro only).
