Apple Motion 4 - Manual (Page 1255)

Once the tracking analysis begins, a progress window opens and track points on motion
path appear in the Canvas. The track point at the current playhead position is emphasized.

The tracking keyframes contained in the behavior appear in the Keyframe Editor.
Because the Analyze Motion behavior does not transform the source object, only the
tracking keyframes appear in the Keyframe Editor. When using a Match Move or Stabilize
behavior, the tracking keyframes appear as well as the transform curves of the source
object (for Stabilize) or destination object (for Match Move).
