# Sync Lipsync 3 API

> Pielāgo jebkura runājoša video lūpu laiku jaunam audio celiņam.

Sync Labs lipsync-3 aizstāj personas mutes kustības video, lai tās atbilstu jaunam balss celiņam, kas paredzēts dublēšanai, reklāmu lokalizācijai un rindu labošanai pēcapstrādē. Ja audio un video garums atšķiras, izvēlieties apgriešanu, cilpošanu, atkārtošanu, aizpildīšanu ar klusumu vai pārkartēšanu.

- Model id: `sync-lipsync/v3`
- Made by: Sync Labs
- Category: Lipsync & Avatars
- Output: video
- Price per minute of your output video: $8.00 / minute of output video (cheapest run $8.00 (8000 API credits))
- Run: `POST https://api.doitong.com/v1/run/sync-lipsync/v3`
- Quote: `POST https://api.doitong.com/v1/quote/sync-lipsync/v3`
- Docs page: https://doitong.com/lv/developers/models/sync-lipsync/v3

## Pricing

Price: **$8.00 / minute of output video**. Price per minute of your output video: the input files are measured before the run (length, resolution, frame rate). The quote measures the same files and is exactly what the run charges.

The full example input below costs $1.334 = 1334 API credits (0.1667 min output video × $8.00).

Prices are the upstream price in USD, paid from the API balance in API credits (1000 API credits = 1 USD). `POST https://api.doitong.com/v1/quote/sync-lipsync/v3` with the same JSON body returns the exact price for that input; the quote is exactly what a run charges. Invalid input is never charged and failed or canceled requests are refunded automatically.

## Input parameters

Send either the canonical name or the native field name (not both). Canonical names are the same across models.

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `video_url` | `video` | string (video URL) | yes |  |  | URL, kas norāda uz ievades video. |
| `audio_url` | `audio` | string (audio URL) | yes |  |  | Ievades audio atrašanās vieta URL formā. |
| `sync_mode` |  | enum (string) | no | `cut_off` | `cut_off`, `loop`, `bounce`, `silence`, `remap` | Lūpu sinhronizācijas režīms audio un video ilguma atšķirību apstrādei. |
| `options` |  | object {sync_mode, model_mode, prompt, temperature, active_speaker_detection, occlusion_detection_enabled} \| null | no |  |  | Šeit konfigurējiet papildu Sync.so ģenerēšanas darbību; iesniegtajām options.sync_mode vērtībām ir priekšroka pār augšējā līmeņa sync_mode vērtību. |
| `options.sync_mode` |  | enum (string) \| null | no |  | `cut_off`, `loop`, `bounce`, `silence`, `remap` | Augšējā līmeņa sync_mode aizstājējs, kas nosaka darbību, ja ievades audio un video ilgums atšķiras. |
| `options.model_mode` |  | enum (string) \| null | no |  | `lips`, `face`, `head`, `lipsync`, `emotion`, `talking_head` | Rediģēšanas apgabala izvēle, galvenokārt react-1, norādot, kuru reģionu modelis pārveido. |

| `options.temperature` |  | number \| null | no |  | 0 – 1 | Izteiksmīguma iestatījums, kas neietekmē sync-3, jo tas to pārvalda iebūvēti. Modeļiem, kas izmanto šo iestatījumu, 0 nodrošina vismazāk izteiksmīgu lūpu sinhronizāciju, bet 1 — visizteiksmīgāko. |
| `options.active_speaker_detection` |  | object {auto_detect, v3, use_v2, frame_number, coordinates, bounding_boxes, bounding_boxes_url, face_image} \| null | no |  |  | Iestatījumi aktīvā runātāja noteikšanai videoklipos ar vairākiem cilvēkiem. |
| `options.active_speaker_detection.auto_detect` |  | boolean \| null | no |  |  | Automātiska aktīvā runātāja noteikšana un ģenerēšanas piemērošana šai personai. |
| `options.active_speaker_detection.v3` |  | boolean \| null | no |  |  | V3 aktīvā runātāja noteikšanas izmantošana. |
| `options.active_speaker_detection.use_v2` |  | boolean \| null | no |  |  | Novecojis v2 aktīvā runātāja noteikšanas iestatījums. |
| `options.active_speaker_detection.frame_number` |  | integer \| null | no |  | ≥ 0 | Kadra indekss, ko izmanto koordinātēm manuāli izvēlētā runātāja noteikšanai. |
| `options.active_speaker_detection.coordinates` |  | array of integer \| null | no |  | 2 – 2 items | Sejas atskaites punkts [x, y] formā runātājam frame_number. |
| `options.active_speaker_detection.bounding_boxes` |  | array of array of integer \| null | no |  |  | Noteiktie sejas ierobežojošie taisnstūri katram kadram, izteikti kā [x1, y1, x2, y2]. |
| `options.active_speaker_detection.bounding_boxes_url` |  | string \| null | no |  |  | JSON faila URL, kas nodrošina ierobežojošos taisnstūrus katram kadram. |
| `options.active_speaker_detection.face_image` |  | string \| null | no |  |  | Base64 kodēts sejas attēls manuālai runātāja izvēlei. |
| `options.occlusion_detection_enabled` |  | boolean \| null | no |  |  | Aizklājuma noteikšanas slēdzis; sync-3 gadījumā tas neko neietekmē, jo noteikšana ir automātiska, citādi tas nosaka, vai ģenerēšanā ietvert aizklājuma noteikšanu. |

File parameters (`video`, `audio`) take a public `https://` URL, a `data:` URI up to 10 MB, or the `file_url` of an upload from `POST /files`.

## Example input

Required parameters only:

```json
{
  "video": "https://content.doitong.com/video/showcase/v3/avatar/talking_avatar_loop.mp4",

}
```

## Run it

Set `DOITONG_API_KEY` to a key from https://doitong.com/developers/dashboard#keys. `?wait=20` returns the finished request in the same call when it is ready within 20 seconds; otherwise poll `GET /requests/{id}` (it also accepts `?wait=`), or pass `webhook_url`.

### curl

```bash
# Run the model; wait up to 20 s for the finished result in the same call
curl -X POST "https://api.doitong.com/v1/run/sync-lipsync/v3?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "video": "https://content.doitong.com/video/showcase/v3/avatar/talking_avatar_loop.mp4",
    "audio": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
  }'

# Still "queued" or "running"? Poll with the id from the response:
curl "https://api.doitong.com/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

  "Authorization": "Bearer " + process.env.DOITONG_API_KEY,
  "Content-Type": "application/json",
};

// Run the model; wait up to 20 s for the finished result in the same call
let res = await fetch(API + "/run/sync-lipsync/v3?wait=20", {

  }),
});
let request = await res.json();
if (!res.ok) throw new Error(request.error.code + ": " + request.error.message);

// Not finished yet: long-poll until it is
while (request.status === "queued" || request.status === "running") {
  res = await fetch(API + "/requests/" + request.id + "?wait=20", { headers });
  request = await res.json();
}
if (request.status !== "succeeded") throw new Error(JSON.stringify(request.error));
console.log(request.outputs.map((o) => o.url), request.cost.credits + " API credits ($" + request.cost.usd + ")");
```

### Python

```python
import os
import requests

API = "https://api.doitong.com/v1"
headers = {"Authorization": "Bearer " + os.environ["DOITONG_API_KEY"]}

payload = {
    "video": "https://content.doitong.com/video/showcase/v3/avatar/talking_avatar_loop.mp4",
    "audio": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3",

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/sync-lipsync/v3", params={"wait": 20}, json=payload, headers=headers)
request = r.json()
if not r.ok:
    raise RuntimeError(request["error"]["code"] + ": " + request["error"]["message"])

# Not finished yet: long-poll until it is
while request["status"] in ("queued", "running"):
    request = requests.get(API + "/requests/" + request["id"], params={"wait": 20}, headers=headers).json()
if request["status"] != "succeeded":
    raise RuntimeError(request["error"])
print([o["url"] for o in request["outputs"]], request["cost"]["credits"], "API credits", "$" + request["cost"]["usd"])
```

### MCP

The MCP server at `https://api.doitong.com/v1/mcp` exposes the tools `search_models`, `get_model`, `quote`, `run`, `get_request`, `cancel_request`, `list_requests`, `create_upload` and `get_account`. A `run` call for this model:

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "run",
    "arguments": {
      "model_id": "sync-lipsync/v3",
      "input": {
        "video": "https://content.doitong.com/video/showcase/v3/avatar/talking_avatar_loop.mp4",
        "audio": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
      },
      "wait_seconds": 20
    }
  }
}
```

## Response

Every call returns a request object. `status` is one of `queued`, `running`, `succeeded`, `failed`, `canceled`. `outputs` lists the generated files with URLs on our storage (kept forever, or 7 days with `?storage=temporary`; `storage` says which); `output` is the model's own result object with the same URLs.
