Storyboard
Definition
The scene-by-scene plan of a video — each scene with its narration, on-screen text, visual and timing — created before anything is rendered.
A storyboard breaks a script into scenes. Each scene carries its own narration line, on-screen caption, visual direction, camera motion and duration.
In an AI pipeline, the storyboard is the editable layer: you tweak one scene's text or image instead of regenerating the whole video. Getting the storyboard right is what makes the final render feel intentional rather than random.
