Parameters

promptrequired
string

Describe motion, action, and scene with cinematic cues.

audio_urloptional
string (uri)

Audio URL to sync character motion and lip movement.

Default: null
durationoptional
integer

Video length in seconds, 2-15. Shorter for previews.

Default: 5
imageoptional
string (uri)

First frame of the video. Model animates from this image.

Default: "https://segmind-resources.s3.amazonaws.com/input/wan27-i2v-input.png"
last_frameoptional
string (uri)

Ending frame for smooth transition between start and end.

Default: null
negative_promptoptional
string

Elements to suppress in output. Common: blurry, distorted hands.

Default: "blur, distortion, artifacts, watermark, text"
resolutionoptional
string

Output resolution. 720P faster; 1080P for final delivery.

Default: "720P"
Allowed values :
"720P""1080P"
seedoptional
integer

Fixed seed for reproducible output. Leave empty for random.

Default: null

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/wan2.7-i2v

    Submitreturns request_id, status_url, response_url

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

    Polluntil COMPLETED or FAILED

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

Status states

QUEUEDAccepted, waiting for a worker
PROCESSINGRunning on a worker
COMPLETEDDone — result body is ready
FAILEDErrored (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.
