This chapter describes how to create and customize effects that alter motion in a clip. You use traditional motion effects to change the speed at which the video plays or to create a strobe motion effect. Creating a traditional motion effect results in a clip that has a uniform speed from beginning to end. The Timewarp effect category contains effects with which you can vary the speed during the clip. For example, you can start the clip at 0% (stopped) and ramp up to 100% (full speed).

This chapter also describes two effects with which you can control apparent camera movement. You use the Region Stabilize effect to stabilize a clip that exhibits unwanted motion, such as motion from an unstable camera. You use the Avid Pan and Zoom effect on an imported graphic image to simulate a camera's motion (pan) and magnification (zoom) over the field of view.
