API Endpoint

POSThttps://api.segmind.com/v1/grok-imagine-video-1.5-image-to-video

Parameters

imagerequired
string (uri)

Source still animated as the first frame; accepts a public URL or base64. Match its orientation to your chosen aspect ratio.

aspect_ratiooptional
string

Frame shape of the output. 16:9 for landscape, 9:16 for Reels and Shorts, 1:1 for feeds.

Default: "16:9"
Allowed values :
"16:9""9:16""1:1""4:3""3:4""3:2""2:3"

Array items:
imagerequired
string (uri)

Image that appears at this moment.

timestamp_srequired
number

Seconds from the start, strictly between 0 and the duration.

Default: 3
last_frameoptional
string (uri)

Optional image the clip ends on. Adds $0.0135 and limits output to 720p.

promptoptional
string

Optional text directing motion, camera moves and sound. Describe action and audio together, and put key beats first.

Default: "The camera pushes in slowly as the wave crests, spray catching the sunset light."
reference_audiosoptional
string[]

string

Output resolution: 480p, 720p or 1080p. 1080p is only available without Last Frame, Keyframes, Voice or Reference Audios.

Default: "480p"
Allowed values :
"480p""720p""1080p"
voice_idoptional

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/grok-imagine-video-1.5-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.
