# Storyboard previews

A storyboard preview is an MP4 (1280x720) of the current storyboard: the scene clips in film order with the voice-over
and a visible watermark. Use it to review a film in your own system before it is finished, for example together with
[feedback](/api/feedback) on single scenes.

- Each new preview costs credits (currently 100). A preview of an unchanged storyboard is reused and not charged again.
- Creating a preview is a [long-running operation](/api/long-running-operations): you get `202` and poll the operation.
- Previews are kept for a limited time (`expires_at`); after that, request a new one.
- A preview is never the approved film.
