•
Transition: A slider that determines how far into the behavior the camera stops moving and
the camera’s Angle of View parameter begins to animate instead.
If Transition is set to 50% in a Zoom Layer behavior that has a length of 300 frames, the camera
move takes 150 frames to arrive at the position of the target object and then stops moving for
the duration of the behavior, and the camera’s Angle of View parameter animates over the rest
of the duration. If Transition is set to 100%, the camera move takes the full 300 frames to arrive
at the position of the target object, and the camera’s angle of view does not animate. If the
Zoom Layer behavior’s duration is 100 frames and Transition is set to 50%, the camera move
takes 50 frames to arrive at the position of the target object.
•
Speed: A pop-up menu that sets the type of interpolation used for the rotation. The value can
be set to Constant, Ease In, Ease Out, Ease Both, Accelerate, or Decelerate.
•
Zoom: A slider that sets a proportional value to modify the camera’s Angle of View parameter.
A nonzero value determines how much the angle of view (and thus perspective) changes
relative to the camera’s initial angle of view. A zero value for Zoom leaves the Angle of View
parameter unchanged.
The HUD contains the same controls as the Inspector.
Lighting
Lighting overview
You can apply lighting to a motion graphics project to enhance the depth and scope of
compositions, and to help create realistic environments for composites. Although light sources
are not visible, you can simulate a visible light source by combining a point light with an image
or shape (the simulated light source).

Note: Use the Match Move behavior to move a simulated light source with a light in a movie
clip. For more information on the Match Move behavior, see
Basic Match Move workflows on
page 962.
Motion’s lighting system works only on 3D groups and their children.
Add a light to a project
m Choose Object > New Light (or press Shift-Command-L).
A light object is added to the Layers list, the Timeline, and the Canvas (represented by a
wireframe icon), and the 3D Transform tool in the toolbar becomes active.
