promptrequiredstringDescribe the scene, subject and motion. Up to 7000 characters.
durationoptionalintegerLength of the generated video. Cost scales per second.
6Range: 5 - 15first_frame_imageoptionalstring (uri)Opening frame of the video. Send it, a last frame, or both.
last_frame_imageoptionalstring (uri)Optional closing frame; with a first frame the video interpolates between them.
prompt_expansion_modeoptionalstringHow much MiniMax rewrites the prompt before generating.
"balanced""disabled""balanced""quality"resolutionoptionalstringOutput resolution.

Returns: Video
Asynchronous requests (v2)
Use Async for video, long-running (>~60s), or high-concurrency workloads; Sync is simplest for fast image & LLM calls. Async submits a request and you poll it to completion.
- 1
POST /v2/minimax-h3-max-image-to-videoSubmit — returns request_id, status_url, response_url
- 2
GET /v2/requests/{id}/statusPoll — until COMPLETED or FAILED
- 3
GET /v2/requests/{id}Result — final response body
Status states
- A FAILED request is served as HTTP 422 — the body still carries the error detail.
- An unknown or expired request_id returns HTTP 404.
- Results are retained for 1 hour, then expire.
- Content / RAI blocks surface as FAILED, not a separate state.
- Track completion by polling the status endpoint.
