# Seedance 2.0 Reference to Video API

> Stýrir 4 til 15 sekúndna klippu með hljóði úr allt að 9 myndum, 3 myndböndum og 3 hljóðklippum sem vísað er í með nafni.

Fjölviðmiðunarmyndbandslíkan ByteDance: hladdu upp persónum, vörum, staðsetningum, hreyfi- eða myndavélarviðmiði og radd- eða tónlistarklippu og kallaðu á þau í prompti sem @Image1, @Video1, @Audio1 og svo framvegis. Það heldur auðkennum stöðugum milli klippa og myndar samstillt hljóð. Að minnsta kosti ein mynd eða eitt myndbandsviðmið er nauðsynlegt og öll viðmið saman mega ekki fara yfir 12 skrár. Úttak frá 480p til 4K.

## Pricing

Price: **from $0.141 / second (4 s ≈ $0.564)** (the lowest tier; the quote prices your exact input). Billed per second of output (`duration`, default 15).

Price rules (the first rule that matches the input wins; a parameter you leave out counts as its default):

- When `video_urls` is set and `duration` ≤ 4: by `resolution`, 480p: $0.141, 720p: $0.304, 1080p: $0.682, 4k: $1.556 / second
- When `video_urls` is set and `duration` ≤ 5: by `resolution`, 480p: $0.141, 720p: $0.304, 1080p: $0.682, 4k: $1.556 / second

- When `video_urls` is set: by `resolution`, 480p: $0.141, 720p: $0.304, 1080p: $0.682, 4k: $1.556 / second
- When `resolution` is 480p, 720p, 1080p, 4k: by `resolution`, 480p: $0.141, 720p: $0.304, 1080p: $0.682, 4k: $1.556 / second

The full example input below costs $1.52 = 1520 API credits (5 s × 304 API credits).

Prices are the upstream price in USD, paid from the API balance in API credits (1000 API credits = 1 USD). `POST https://api.doitong.ru/v1/quote/bytedance/seedance-2.0/reference-to-video` 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 |
|---|---|---|---|---|---|---|
| `prompt` |  | string | yes |  |  | Textakvaðning sem stýrir efnisgerð myndbands. |
| `image_urls` | `images` | array of image URL | no |  | ≤ 9 items | Myndtilvísanir fyrir leiðsögn myndbands, takmarkaðar við 9 myndir og háðar hámarki 12 skráa yfir allar miðlategundir. Hver mynd má mest vera 30 MB og verður að nota JPEG, PNG eða WebP. Notaðu @Image1, @Image2 og síðari númeruð merki til að auðkenna tilvísanirnar í kvaðningunni. |
| `video_urls` | `videos` | array of video URL | no |  | ≤ 3 items | Myndbandstilvísanir fyrir efnisgerð, gefnar upp sem MP4- eða MOV-skrár og auðkenndar í kvaðningunni með @Video1, @Video2 og síðari númeruðum merkjum. Hver þarf að hafa upplausn frá um það bil 480p (640x640) upp í um það bil 720p (834x1112). Mengi þeirra er takmarkað við 3 myndbönd sem eru samtals innan við 50 MB, með samanlagða lengd frá 2 til 15 sekúndum. |
| `audio_urls` | `audios` | array of audio URL | no |  | ≤ 3 items | Hljóðtilvísanir fyrir leiðsögn myndbands krefjast að minnsta kosti einnar meðfylgjandi mynda- eða myndbandstilvísunar. Gefðu upp MP3- eða WAV-skrár sem eru mest 15 MB hver, að hámarki 3 skrár og með samanlagða lengd að hámarki 15 sekúndur. Auðkenndu þær í kvaðningunni með @Audio1, @Audio2 og síðari númeruðum merkjum. |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `720p`, `1080p`, `4k` | Úttaksupplausn: 480p leggur áherslu á hraða, 720p býður upp á jafnvægi, 1080p gefur mikil gæði og 4k hæstu gæðin. |
| `duration` |  | enum (string) | no | `auto` | `auto`, `4`, `5`, `6`, `7`, `8`, `9`, `10`, `11`, `12`, `13`, `14`, `15` | Val á lengd myndbands: `auto` felur líkaninu valið með kvaðningunni, en ákveðin lengd verður að vera frá 4 til 15 sekúndur. |
| `aspect_ratio` |  | enum (string) | no | `auto` | `auto`, `21:9`, `16:9`, `4:3`, `1:1`, `3:4`, `9:16` | Hlutfall úttaks: 16:9 gefur landslag, 9:16 andlitsmynd/lóðrétt, 1:1 ferning og 21:9 kvikmyndalegt ofurbreitt snið. Veldu `auto` til að láta líkanið velja hlutfallið. |
| `generate_audio` |  | boolean | no | `true` |  | Virkjaðu þetta til að fylgja myndbandinu eftir með samstilltu hljóði. Myndað hljóð inniheldur tal sem passar við varahreyfingar, umhverfishljóð og hljóðbrellur. |
| `bitrate_mode` |  | enum (string) | no | `standard` | `standard`, `high` | Veldu bitahraða úttakskóðunar: 'standard' heldur sjálfgefnu gildi, en 'high' biður líkanið um betri kóðun á kostnað stærri skráar. |
| `codec` |  | enum (string) | no | `auto` | `auto`, `H264`, `H265` | Val á myndbandskóðalykli: `auto` breytir sjálfgefinni hegðun ekki, `H264` velur H.264 og `H265` velur H.265. |

File parameters (`images`, `videos`, `audios`) 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
{
  "prompt": "@Image1 The banana manager walks through the office and high-fives the carrot, upbeat comedy tone"
}
```

## 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.ru/v1/run/bytedance/seedance-2.0/reference-to-video?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \

    ],
    "resolution": "720p",
    "duration": 5
  }'

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

### MCP

The MCP server at `https://api.doitong.ru/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": "bytedance/seedance-2.0/reference-to-video",
      "input": {
        "prompt": "@Image1 The banana manager walks through the office and high-fives the carrot, upbeat comedy tone",
        "images": [
          "https://content.doitong.com/images/gp/image_20260610003801_541d9719_316882.png"
        ],
        "resolution": "720p",
        "duration": 5
      },
      "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.
