API Endpoint

POSThttps://api.segmind.com/v1/gemini-omni-1.2-flash-extend

Parameters

videorequired
string (uri)

The source video to continue, 27 seconds or less. Source plus added seconds total 30 seconds at most.

durationoptional
integer

Seconds to add to the source (3-10). The output is the source plus these seconds, 30 seconds at most.

Default: 5Range: 3 - 10
promptoptional
string

Describe the next beat to add. Leave empty for a natural continuation of the scene.

resolutionoptional
string

Output resolution (360p, 720p, 1080p, 4K). Leave empty to keep the source's; setting one re-renders the whole clip.

Allowed values :
"360p""720p""1080p""4k"
seedoptional
integer

Random seed for the added seconds. Use -1 for random, or fix an integer to reproduce a take.

Default: -1

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/gemini-omni-1.2-flash-extend

    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.
