60 Chapter 2 Motion Tracking
In the following example, only Position is enabled in the Adjust row of the Behaviors
tab. As a result, the white elliptical shape does not change its scale or rotation based on
the position of the two trackers.
In the next example, Position, Scale, and Rotation are enabled in the Adjust row of the
Behaviors tab. Consequently, the white elliptical shape changes its position, scale, and
rotation based on the position of the two trackers, preserving the illusion that it is
physically attached to the picture frame.
Note: When using four-point tracking, scale and rotation are automatically applied to
the corner-pinned object.
Using Match Move to Apply Animation Data to a Project Element
You can instantly apply the animation of a source object to a destination object via the
Match Move behavior, without any tracking analysis. The source object can be
animated by behaviors or keyframes.
The following simple example uses a “magic wand” (made up of rectangle shapes) that
is animated on a motion path. The animation of the wand is then tracked to a particle
emitter to create the illusion of sparkles flying off the tip of the wand.
