To maintain storyboard continuity across multiple video chapters, you validate explicit chunk checkpoints and tail frame references to prevent visual drift. This process ensures traceable handoffs between shots by enforcing checkpoints as the source of truth rather than relying on historical text.

To check storyboard continuity for a video sequence, you need to provide the current chapter text, storyboardChunks, and a tailFrameUrl. These explicit inputs enable the system to determine whether to continue, redo, or repair scene continuity boundaries.

Repair continuity drift in a long-form storyboard by running an end-to-end audit that checks for conflicts and missing data. The system outputs a structured continuation plan with anchors for the chapter, chunk, and tail-frame, plus recommended next actions for targeted resynchronization.

You should use an explicit checkpoint instead of historical text for narrative planning whenever you need to assess continuity boundaries. Relying on explicit checkpoints as the source of truth prevents drift and ensures factual traceability across single videos or multi-chapter sequences.

A tail frame, provided via a URL, is an explicit checkpoint that enforces storyboard continuity by serving as a visual anchor for the end of a shot. Validating this tail frame reference ensures traceable handoffs and prevents drift when continuing to the next scene.
