What are the types of motion tracking behaviors?
There are six tracking behaviors in Motion:
Analyze Motion
Generates and stores tracking information from a video clip, but does not apply that tracking data to other objects. However, other tracking behaviors can apply Analyze Motion tracking results to objects. The Analyze Motion behavior lets you add multiple trackers to a clip, to track multiple reference patterns at the same time. The Analyze Motion behavior is available in the Motion Tracking subcategory of behaviors. See Analyze the motion of a clip.
Match Move
Matches a foreground element to a background element so they appear locked together. Using Match Move, you can analyze one or more reference points in a video clip, then apply that tracking data to nearly any other object in your project, or you can apply tracking data supplied by another tracking behavior (such as Analyze Motion or Stabilize). You can also apply animation data created by keyframes or other behaviors (without having to analyze the motion of the animated source object). The Match Move behavior is available in the Motion Tracking subcategory of behaviors. See Match moving overview.
Stabilize
Removes unwanted motion in a video clip, such as camera jitter (horizontal movement, vertical movement, or both). Because the Stabilize behavior analyzes the entire frame of a clip, you don’t need to use onscreen trackers. Stabilize lets you smooth jittery clips while preserving the general motion of the camera, or lock down video clips, stabilizing the camera as if it were on a tripod. The Stabilize behavior is available in the Motion Tracking subcategory of behaviors. See Stabilize a shaky clip.
Unstabilize
Applies the movement recorded by a Stabilize behavior to a clip or object (but does not perform its own tracking analysis). Use Unstabilize to match the camera shake in a movie clip to foreground elements added in post-production. The Unstabilize behavior is available in the Motion Tracking subcategory of behaviors. See Unstabilize a clip.
Track Points
Matches the control points of a shape, paint stroke, or mask to reference features on a video clip. For example, you can draw a mask around a car in a clip and then track the control points of the mask to the moving car, cutting the car out of the background. You can then apply effects to the isolated car, and the surrounding image is not affected. The Track Points behavior can analyze motion in a video clip, then apply that tracking data to points in a shape, or it can use existing tracking data recorded by the Analyze Motion, Match Move, or Stabilize tracking behaviors. The Track Points behavior is available in the Shape subcategory of behaviors. See Track shapes, masks, and paint strokes.
Track
Matches the position parameters of shapes, video clips, or filters to a reference feature of a video clip. For example, you can match the Center parameter of a Circle Blur filter to a person’s face in a video clip. The Track parameter behavior can analyze motion in a video clip, then apply that tracking data to the position parameter of an object, or it can use existing tracking data recorded by another tracking behavior. The Track behavior is available in the Parameter subcategory of behaviors. See Track a filter’s position parameter.
