A storyboard is a visual script that depicts how a video will be filmed through a series of diagrams. Each diagram shows a sketch of the video image along with notes for things like camera angles, lighting, audio, and shot length. Storyboards are created during pre-production and used throughout production and post-production to provide a foundation for capturing footage and making editing decisions. They help ensure all those involved have the same understanding of how the video will be structured and filmed.
