 Some feature film DVD "special features" include production animatics, which may have scratch vocals or may even feature vocals from the actual cast (usually where the scene was cut after the vocal recording phase but before the animation production phase).Animatics are also used by advertising agencies to create inexpensive test commercials.A variation, the "rip-o-matic", is made from scenes of existing movies, television programs or commercials, to simulate the look and feel of the proposed commercial.
