Motion Tracking and Stabilization
Using the new Motion Tracking behaviors, you can stabilize handheld camera shots,
track the individual points of a shape or mask to background element, and more. The
new Motion Tracking behaviors include:
Â
Match Move : Apply tracking data to from one element in the Canvas to another,
thereby “locking” them together. For example, you can match an image file of a logo
to the background video of a billboard so that the logo appears to be superimposed
on the billboard even when the camera moves. Additionally, you can apply the
transformation data of an animated source object to another destination object
without analysis. As a result, the destination object moves just like the source object.
 Stabilize : Analyze a movie or image sequence with the Stabilize behavior to remove
unwanted movement. For example, use the Stabilize behavior to smooth handheld
camera shots.
 Unstabilize : Restore movement to a previously stabilized clip. This behavior is useful
when you’ve stabilized a video clip in order to add a foreground effect but wish to
restore camera movement to the final composite. After you’ve completed the
foreground effects work, use the Unstabilize behavior to reapply the original motion
data to the both the original background element and also the new foreground
elements.
 Track Points: Track the control points of a shape or mask (including paint strokes) to
moving elements in a clip. For example, you can draw a mask around a car in a movie
clip, then track the control points of the mask to the edges of the moving car,
thereby isolating the car from the rest of the clip. You can then apply effects to the
isolated car without affecting surrounding areas of the clip. The Track Points behavior
also allows you to apply existing tracking data recorded by the Analyze Motion,
Match Move, or Stabilize tracking behaviors to the control points of a shape or mask.
 Track Parameter: Track a parameter of a filter to single point in a movie clip. For
example, you can make the center point of an applied Light Rays filter follow a
moving light in a clip. In this case, the tracking data is applied to a single parameter
of the filter (the Center parameter), rather than to the filter as a whole.
