The regeneration problem
Prompt-to-video generators share a failure mode: the output is a single locked artifact. When scene three is wrong, you rewrite the prompt, regenerate the whole video, pay again, and hope scene three improves without scene five getting worse.
That loop is what FrameCompose removes. Generation produces a project with every scene, caption, and audio track exposed on a timeline. The thing that is wrong is the only thing you touch.
