https://api.segmind.com/v1/minimax-h3-reference-to-videoParameters
promptrequiredstringDescribe the scene, subject and motion. Up to 7000 characters.
reference_imagesrequiredstring[]1-5 images pinning the subject's appearance. The prompt drives the action.
durationoptionalintegerLength of the generated video. Cost scales per second.
6Range: 4 - 15ratiooptionalstringOutput aspect ratio. 'adaptive' matches the reference images.
"adaptive""adaptive""21:9""16:9""4:3""1:1""3:4""9:16"resolutionoptionalstringOutput resolution. 2K is the only tier generally available.
"2K""2K"Response Type
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-reference-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.
