storyboard

A film storyboard is essentially a large comic of the film or some section of the film produced beforehand to help film directors, cinematographers and television commercial advertising clients visualize the scenes and find potential problems before they occur. Often storyboards include arrows or instructions that indicate movement.
In creating a motion picture with any degree of fidelity to a script, a storyboard provides a visual layout of events as they are to be seen through the camera lens. And in the case of interactive media, it is the layout and sequence in which the user or viewer sees the content or information. In the storyboarding process, most technical details involved in crafting a film or interactive media project can be efficiently described either in picture, or in additional text.
Some live-action film directors, such as Joel and Ethan Coen, used storyboard extensively before taking the pitch to their funders, stating that it helps them get the figure they are looking for since they can show exactly where the money will be used. Alfred Hitchcock's films were strongly believed to have been extensively storyboarded to the finest detail by the majority of commentators over the years, although recent research indicates that this was exaggerated for publicity purposes. Other directors storyboard only certain scenes, or none at all. Animation directors are usually required to storyboard extensively, sometimes in place of writing a script.
