API Endpoint

POSThttps://api.segmind.com/v1/minimax-h3-max-image-to-video

Parameters

promptrequired
string

Describe the scene, subject and motion. Up to 7000 characters.

Default: 6Range: 5 - 15
first_frame_imageoptional
string (uri)

Opening frame of the video. Send it, a last frame, or both.

last_frame_imageoptional
string (uri)

Optional closing frame; with a first frame the video interpolates between them.

prompt_expansion_modeoptional
string

Default: "balanced"
Allowed values :
"disabled""balanced""quality"
resolutionoptional
string

Output resolution.

Default: "768P"
Allowed values :
"480P""768P"

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. 1
    POST /v2/minimax-h3-max-image-to-video

    Submit — returns request_id, status_url, response_url

  2. 2
    GET /v2/requests/{id}/status

    Poll — until COMPLETED or FAILED

  3. 3
    GET /v2/requests/{id}

    Result — final response body

Status states

QUEUED— Accepted, waiting for a worker
PROCESSING— Running on a worker
COMPLETED— Done — result body is ready
FAILED— Errored (incl. content/RAI blocks)
  • 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.
