When to use the Videos API

The core of the API. Create a video from a brief we script for you or from a script you supply, watch the render, change parts of it, and export the result.

Creation is asynchronous. POST /videos returns 202 with a video id while the render continues in the background, so a client either polls GET /videos/{id} at the interval the response asks for, or subscribes to a webhook and stops polling entirely.

The editing endpoints are the reason to use the API over a one-shot generator. A finished video is not final: you can regenerate a single scene without re-rendering the rest, swap the voiceover for a different voice, edit the script or caption settings, and export again. Re-running one scene costs a fraction of what re-running the whole video does.

Videos API questions

How long does an API video render take?
Minutes, not seconds. POST /videos returns immediately with a video id and a poll_after_seconds hint; treat the render as a background job rather than something to block a request on.
Can I regenerate one scene instead of the whole video?
Yes. POST /videos/{id}/scenes/{n}/regenerate re-renders a single scene, optionally with new narration, leaving every other scene untouched. It is the cheapest way to fix one bad shot.
How do I avoid being charged twice for a retried request?
Send an idempotency_key on POST /videos. Without one, a retry after a dropped connection creates and charges for a second video, because the server cannot tell a retry from a new request.
How do I download the finished MP4?
GET /videos/{id}/download returns a signed download URL. Captions come separately from GET /videos/{id}/captions as an SRT or VTT file rather than JSON.
Can I cancel a render that is already running?
Yes. POST /videos/{id}/cancel stops a running render and releases the credits it had reserved.
