A series of simple pictures that depict the important changes of scene and action in a planned film or video production. In the production of an animated film, for example, a series of sketches, comparable to a comic strip, which outlines the narration of a scene; its visual and audial changes. Traditionally, these drawings are tacked to a bulletin board, arranged, re-arranged and replaced as the story takes shape. Early rough storyboard drawings are thumbnail sketches, while more detailed drawings are called "finished" or "final storyboard panels."Also see animation, panel, sequencing, and time.
