# VEED Lipsync v2 (lipsync) > VEED Lipsync v2 re-lips a video that already exists to a new audio track. It keeps the original motion, camera and background, and it is the cheapest lipsync model per second. Status: roasOS API v1.1. Catalog `model-catalog@2026-10-06.v5`, pricing `customer-pricing@2026-11-05.v15`. The endpoint `POST /v1/lipsync/veed-lipsync-v2` is live. `POST /v1/generations` stays for one minor version as a deprecated alias (see "Today"). ## Endpoint POST https://api.roasos.com/v1/lipsync/veed-lipsync-v2 Auth: Authorization: Bearer roasos_sk_… (scope api:write). Idempotency-Key required. quote_only / quote_id / webhook_url as in https://docs.roasos.com/llms.txt. ## Good at Change the script of a finished ad. Make one shoot speak a second language. Send the source video and the new audio; the model articulates the mouth of the person in the video. It is the only lipsync model that takes a video, and the only one that does not accept `image_url` or `avatar_id`. It has no prompt. ## Pricing Unit: second. Pricing key: `veed-lipsync-v2`. | request | credits | |---|---| | `10s` | 9 | Credits come from the roasOS pricing table (`MODEL_COSTS`) through the catalog. No other field changes the price. ## Modes - `video-audio-to-video` Provider endpoints: `veed/lipsync/v2`. ## Request fields | field | type | required | default | rule | |---|---|---|---|---| | `audio_url` | string | yes | — | https URL; ≤ 4,096 characters | | `media_rights` | object | no | — | `{ accepted, statement_version }` | | `quote_id` | string | no | — | UUID | | `quote_only` | boolean | no | `false` | — | | `video_url` | string | yes | — | https URL; ≤ 4,096 characters | | `wait_timeout_seconds` | integer | no | `0` | 0–60 | | `webhook_url` | string | no | — | https URL; ≤ 4,096 characters | The schema is strict: a field that is not in this table returns `400 unsupported_option`. Field names are the roasOS role names, one name per role across every family. ## Media - `video_url` — the source video - `audio_url` — the driving audio track | role | items | max size | content types | duration | |---|---|---|---|---| | `audio_url` | ≤ 1 | 15 MB | `audio/mp3`, `audio/mpeg`, `audio/wav`, `audio/wave`, `audio/x-wav` | 0–60 s | | `video_url` | ≤ 1 | 100 MB | `video/mp4`, `video/quicktime` | — | - Refused: `avatar_id`, `elements`, `product_id`, `product_images`, `references`, `reference_images`, `image_url`, `end_image_url`, `scene_id`, `scene_image`, `video_urls`, `audio_urls`, `voice_id`. A refused role returns `400 unsupported_option`. - Every URL must be an immutable object on `https://cdn.roasos.com/…` that your workspace owns; any other URL is `400 reference_media_not_workspace_owned`. Upload with `POST /v1/uploads` (direct POST of the bytes to `put_url`, or a `source_url` import), then use the returned CDN URL. ## Prompt None. ## Not exposed The catalog records no pinned or hidden provider field for this model. ## Result Result kind `lipsync`. Always present: `url`. ```json { "data": { "id": "gen_…", "kind": "lipsync", "model": "veed-lipsync-v2", "status": "completed", "result": {"url":"https://cdn.roasos.com/workspaces/ws_01/result"} } } ``` Files live on `https://cdn.roasos.com` and are immutable; a result URL can be a media input to the next call. Poll `GET /v1/jobs/{id}/status` → `{ id, status, updated_at }`, then `GET /v1/jobs/{id}/result` (`409 run_not_completed` until the job is `completed`, `failed` or `canceled`). Statuses: `queued → processing → completed | failed | canceled`. ## Example ```bash # 1. quote — nothing is spent curl -X POST https://api.roasos.com/v1/lipsync/veed-lipsync-v2 \ -H "Authorization: Bearer roasos_sk_live_…" \ -H "Idempotency-Key: 0f1c9e2a-veed-lipsync-v2-0001" \ -H "Content-Type: application/json" \ -d '{"quote_only":true,"audio_url":"https://cdn.roasos.com/workspaces/ws_01/uploads/audio_url.mp3","video_url":"https://cdn.roasos.com/workspaces/ws_01/uploads/video_url.mp4"}' # → 200 { "data": { "kind": "quote", "quote_id": "q_7Hk…", "credits": 9, "expires_at": "…", "confirmation": { "model": "veed-lipsync-v2", "example": "10s" } } } # 2. run — the same body and the same Idempotency-Key, quote_id instead of quote_only curl -X POST https://api.roasos.com/v1/lipsync/veed-lipsync-v2 \ -H "Authorization: Bearer roasos_sk_live_…" \ -H "Idempotency-Key: 0f1c9e2a-veed-lipsync-v2-0001" \ -H "Content-Type: application/json" \ -d '{"quote_id":"q_7Hk…","audio_url":"https://cdn.roasos.com/workspaces/ws_01/uploads/audio_url.mp3","video_url":"https://cdn.roasos.com/workspaces/ws_01/uploads/video_url.mp4"}' # → 201 { "data": { "id": "gen_…", "kind": "lipsync", "model": "veed-lipsync-v2", "status": "queued", "credits_reserved": 9, "links": { "status": "/v1/jobs/gen_…/status", "result": "/v1/jobs/gen_…/result" } } } # 3. poll curl https://api.roasos.com/v1/jobs/gen_…/status -H "Authorization: Bearer roasos_sk_live_…" curl https://api.roasos.com/v1/jobs/gen_…/result -H "Authorization: Bearer roasos_sk_live_…" ``` ## Today The endpoint is `POST /v1/lipsync/veed-lipsync-v2` with `video_url` and `audio_url`. The deprecated alias does not carry this model: `POST /v1/generations` `{ "type": "lipsync" }` returns 503 `lipsync_public_authority_unavailable` for every lipsync model except `ltx-lipsync`, and it has no video field at all. ## See also https://docs.roasos.com/models/lipsync/veed-lipsync-v2 · https://api.roasos.com/v1/catalog/lipsync/veed-lipsync-v2 · veed/lipsync/v2
