# Submit a Lipsync 2.0 job

Model: Lipsync 2.0
Endpoint: `POST /v1/lipsync-2.0`

Start an asynchronous job that re-renders a source video with the speaker's mouth matched to a new audio track — for dubbing, voice replacement, or a cleaner take.

**Inputs**

- `video_url` — public URL of the source video
- `audio_url` — public URL of the new audio track to lip-sync the video to

**What happens next**

The job is **accepted immediately** — you get `202 Accepted` with a `job_id` and status `PROCESSING`. Rendering runs in the background; poll `GET /v1/lipsync-2.0/{job_id}` until the job is `COMPLETED` or `FAILED`.

## Request body

- `audio_url` · url · required — URL of the new audio track to lip-sync the video to.
- `video_url` · url · required — URL of the source video to dub.

## Parameters

- `X-Veed-Store-IO` (header) — Set to `0` to not store this request's and response's bodies. They are then not available in your request logs for debugging.
- `X-Veed-Media-Expiration-Seconds` (header) — Number of seconds before the media URLs returned for this request expire. A value above the maximum is capped rather than rejected.
