What is an animatic

A animatic is a rough draft of a film or sequence, consisting of simple story boarded panels that are timed with a soundtrack. This creates a crude draft of a film.
Animatics usually allow for a draft that can fix problems before a full animation is made. This allows for it to be easily changed.
Animatics can be simple or complex ranging from rough drawings to a finished animated sequence.
Some animatics may be able to show camera movements within a sequence, this can be used to present an complex animation layout. It also allows the client to visualize how to animation is going to look like and the animation studio can easily get feedback and change anything without re doing a full animation.
