# SeedVR2 · Video API

> Stækkar myndskeið með tímalegri samkvæmni og vali á umbúðum, gæðum og skrifham

Myndbandsstækkun sem tekur við `video_url`. Stækkaðu um stuðul frá 1 til 10 eða miðaðu við 720p, 1080p, 1440p eða 2160p. Úttakið getur verið X264 mp4, VP9 webm, ProRes 4444 mov eða GIF. `output_quality` er frá low til maximum og `output_write_mode` getur verið fast, balanced eða small.

- Model id: `seedvr/upscale/video`
- Made by: ByteDance
- Category: Upscale
- Output: video
- Price per megapixel of your output video: $0.001 / megapixel of output video (cheapest run $0.001 (1 API credit))
- Run: `POST https://api.doitong.ru/v1/run/seedvr/upscale/video`
- Quote: `POST https://api.doitong.ru/v1/quote/seedvr/upscale/video`
- Docs page: https://doitong.com/is/developers/models/seedvr/upscale/video

## Pricing

Price: **$0.001 / megapixel of output video**. Price per megapixel 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 $1.106 = 1106 API credits (1105.92 MP output video × $0.001).

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/seedvr/upscale/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.

|---|---|---|---|---|---|---|
| `video_url` | `video` | string (video URL) | yes |  |  | Myndband gefið upp til úrvinnslu. |
| `upscale_mode` |  | enum (string) | no | `factor` | `target`, `factor` | Uppkvörðunarhamur: `target` leiðir kvörðunarstuðulinn af umbeðinni upplausn, en `factor` beitir gefnum kvörðunarstuðli beint. |

| `seed` |  | integer \| null | no |  |  | Slembisáð sem notað er við efnisgerð. |
| `noise_scale` |  | number | no | `0.1` | 0 – 1 | Hávaðakvarði sem beitt er við efnisgerð. |
| `output_format` |  | enum (string) | no | `X264 (.mp4)` | `X264 (.mp4)`, `VP9 (.webm)`, `PRORES4444 (.mov)`, `GIF (.gif)` | Snið myndbandsins sem verður til. |
| `output_quality` |  | enum (string) | no | `high` | `low`, `medium`, `high`, `maximum` | Gæðastilling fyrir myndbandið sem verður til. |
| `output_write_mode` |  | enum (string) | no | `balanced` | `fast`, `balanced`, `small` | Hamur sem notaður er til að skrifa myndbandið sem verður til. |

File parameters (`video`) 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.ru/v1/run/seedvr/upscale/video?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.ru/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

```javascript
const API = "https://api.doitong.ru/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/seedvr/upscale/video?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.ru/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/seedvr/upscale/video", 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.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": "seedvr/upscale/video",
      "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.
