Combining animation and tracking data in Motion
When the destination object in a match move operation has no animation of its own, it
precisely follows the motion of the source object. However, if the destination object is also
animated (has its own applied behaviors or keyframes), more complicated motion effects
can be achieved by combining motion paths.
You can specify whether the animation of the destination object is ignored by or added to
the Match Move behavior. You do this in the Match Move Behaviors Inspector, by choosing
one of two options from the Transform pop-up menu:
• Attach to Source: Applies the movement of the source object to the destination object,
but disables any animation inherent in the destination object. (However, you can
reactivate the destination object’s own animation and deactivate the source object’s
recorded track by turning off the Position, Scale, and Rotation buttons in the Adjust row
of the Behaviors Inspector.)
• Mimic Source: Combines the source object’s recorded track with and destination
object’s own animation. In other words, the destination object maintains its own
animation while at the same time mimicking the motion in the source object’s recorded
track. When the Match Move behavior is set to Mimic Source, turning off the Position,
Scale, and Rotation buttons deactivates the source object’s recorded track. For more
information on Attach to Source and Mimic Source, see Match Move controls in Motion.
Stabilize a shaky clip in Motion
Use the Stabilize tracking behavior to smooth shaky motion in a movie or image sequence.
For a full description of Stabilize parameters, see Stabilize controls in Motion.
Using the Stabilize behavior, there are three ways to analyze a clip:
• Use the behavior’s default advanced motion analysis technique that evaluates the entire
frame of a clip to extract movement data without using onscreen trackers.
• Use onscreen trackers that analyze a reference pattern (a small group of pixels) in
the canvas. These are the same trackers used by the Match Move and Analyze Motion
behaviors.
• Use a combination of the advanced motion analysis and onscreen trackers.
Important: For information on using onscreen trackers with the Stabilize behavior, see
Improve stabilization in Motion.
The Stabilize behavior is primarily useful for removing unwanted trembling from less-
than-stable crane or jib arm moves, eliminating teetering from handheld walking shots, or
reducing vibrations in automotive shots.
Note: Motion blur present in the image remains, even though the subject in the shot is
smoothed or locked.
