34 Tutorial 1 The Motion Interface
The center dolphin clip appears first, and the left and right shots appear in sequence.
However, notice that the dolphin’s movement is now in sync between the left and
center shots.
To solve this, you can slip the dolphins1 clip. Slipping a clip changes which frames are
displayed without changing an object’s In or Out point. In other words, a slip allows you
to use a different portion of a clip without changing its duration or location in time.
Note: An object can only be slipped after the object has been trimmed. Because
behaviors and filters contain no footage, they cannot be slipped.
6 Position the pointer over dolphins1, then press Option.
The Slip pointer appears.
7 Option-drag dolphins1 20 frames to the right.
8 Play the project (press the Space bar).
The dolphins are properly staggered.
9 Choose File > Save (or press Command+S) to save the project.
Effects in the Timeline
Effects such as behaviors, filters, and masks appear as bars in the Timeline. This allows
you to control their placement in time and modify their start and end points
independently from the objects that they affect.
