# Sam Audio · Visual Separate API

> İsteğe bağlı maske videosu ve metin istemiyle yönlendirerek bir videonun ses kanalından sesi ayırır

Bir `video_url` alır ve sesinden hedef sesi çıkarır. İsteğe bağlı `mask_video_url`, hedef nesneyi işaretler (hedef için siyah, arka plan için beyaz); `prompt` metin ipucu ekleyebilir. En fazla 4 `reranking_candidates` sıralanabilir ve uzun sesler parçalara ayrılır. Çıktıda wav veya mp3 biçiminde `target` ve `residual` sesleri bulunur.

- Model id: `sam-audio/visual-separate`
- Made by: Meta
- Category: Video to Audio
- Output: json
- Price per 30 seconds of your input video: from $0.05 / 30 seconds of input video (cheapest run $0.05 (50 API credits))
- Run: `POST https://api.doitong.com/v1/run/sam-audio/visual-separate`
- Quote: `POST https://api.doitong.com/v1/quote/sam-audio/visual-separate`
- Docs page: https://doitong.com/tr/developers/models/sam-audio/visual-separate

## Pricing

Price: **from $0.05 / 30 seconds of input video** (the lowest tier; the quote prices your exact input). Price per 30 seconds of your input 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 $0.05 = 50 API credits (1 × 30 s input video × $0.05).

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/sam-audio/visual-separate` 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 |  |  | MP4 veya MOV gibi formatlarda işlenecek video dosyası URL'si. |
| `mask_video_url` |  | string (video URL) \| null | no |  |  | Hedef nesnenin beyaz arka plan üzerinde siyah göründüğü ikili kodlamayı kullanan maske video URL'si. |
| `prompt` |  | string | no | `` |  | Ayırmaya yardımcı olacak hedef sesin doğal dilde açıklaması. |
| `reranking_candidates` |  | integer | no | `1` | 1 – 4 | Sıralama için oluşturulan aday sayısı. |
| `acceleration` |  | enum (string) | no | `balanced` | `fast`, `balanced`, `quality` | İşlemeye uygulanan hızlandırma düzeyi. |
| `max_chunk_duration` |  | number | no | `60` | 10 – 60 | Saniye cinsinden ölçülen geçiş başına ses sınırı; aşıldığında işleme, birlikte harmanlanan örtüşen parçalara geçer. |
| `chunk_overlap` |  | number | no | `5` | 0 – 30 | Çapraz geçiş harmanlamasında kullanılan, saniye cinsinden ölçülen parçalar arası örtüşme uzunluğu. |
| `output_format` |  | enum (string) | no | `wav` | `wav`, `mp3` | Üretilen sesin biçimi. |

File parameters (`video`, `mask_video_url`) 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/gen_fox_cartoon.mp4"
}
```

A fuller example:

```json
{
  "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.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/sam-audio/visual-separate?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
  }'

# 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

```javascript
const API = "https://api.doitong.com/v1";
const headers = {
  "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/sam-audio/visual-separate?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
  }),
});
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_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/sam-audio/visual-separate", 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": "sam-audio/visual-separate",
      "input": {
        "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
      },
      "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.
