Parameters

video_urlsrequired
string[]

Array of videos to merge. Can be either:1. Array of URL strings (order by index)2. Array of objects with video_url and orderMinimum 2, maximum 10 videos

audio_handlingoptional
string

How to handle audio from multiple videos.

Default: "merge"
Allowed values :
"merge""first""none"
fpsoptional
integer

Output video frame rate (frames per second). If 0 or not specified, uses first video's fps.

Default: 0Range: 0 - 120
heightoptional
integer

Output video height in pixels. If 0 or not specified, uses first video's height.

Default: 0Range: 0 - 4320
maintain_aspect_ratiooptional
boolean

Maintain aspect ratio when resizing videos. If true, adds black padding bars. If false, stretches video to fit dimensions.

Default: true
transition_durationoptional
number

Default: 0.5Range: 0.1 - 2
transition_typeoptional
string

Output video width in pixels. If 0 or not specified, uses first video's width.

Default: 0Range: 0 - 7680

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/multi-video-merge

    Submitreturns request_id, status_url, response_url

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

  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.
