Image Rotoscoping
The Roto Matte panel on the Contents panel allows you to add one or more shapes to an image or movie layer to mask dynamically, tracking them as they move in successive frames. This is often referred to as a roto matte or rotoshape.
For more information about creating and editing shapes see Working with Shapes.
