Every film begins with a storyboard that outlines the basic scenes and shots used in a movie. A story board is a visual aid that describes what will occur in a film or animation. It is important to the production process by giving the director and cinematographer an outline of what to follow when filming the movie. Storyboards consist of a series of images that show a quick snapshot of each scene.
When a script is available, it shows the general flow and narrative structure of the media text. But the way to transfer this text into a visual guide is through the storyboard.
Good storyboards are extremely useful for big action sequences or complex scenes.
