# Bytedance Upscaler Upscale Video API

> ارتقای وضوح ویدیو تا حداکثر 8K با پیش‌تنظیم‌ها و گزینه‌های سطح کیفیت، نرخ فریم و عمق بیت

یک `video_url` می‌گیرد و وضوح آن را به `target_resolution` (از 1080p تا 8k) افزایش می‌دهد، یا به‌جای آن از `scale_ratio` بین 1.1 تا 10 استفاده می‌کند. `target_fps` از 24 تا 120 است. `enhancement_preset` برای محتواهایی مانند ugc یا old_film مناسب است، `enhancement_tier` می‌تواند fast، standard یا pro باشد و `bit_depth` برابر 10 یا 12 به سطح pro نیاز دارد.

- Model id: `bytedance-upscaler/upscale/video`
- Made by: ByteDance
- Category: Upscale
- Output: video
- Price per second of your input video: from $0.0072 / second of input video (cheapest run $0.008 (8 API credits))
- Run: `POST https://api.doitong.com/v1/run/bytedance-upscaler/upscale/video`

## Pricing

Price: **from $0.0072 / second of input video** (the lowest tier; the quote prices your exact input). Price per second 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.

Price by tier:

- 1080p: $0.0072 / second of input video
- 2K: $0.0144 / second of input video
- 4K: $0.0288 / second of input video
- 1080p, frame rate: $0.0288 / second of input video
- 2K, frame rate: $0.0576 / second of input video
- 1080p, pro: $0.072 / second of input video
- 6K: $0.0737 / second of input video
- 8K: $0.1152 / second of input video
- 4K, frame rate: $0.1152 / second of input video
- 2K, pro: $0.144 / second of input video
- 4K, pro: $0.288 / second of input video
- 1080p, pro, frame rate: $0.288 / second of input video
- 6K, frame rate: $0.2948 / second of input video
- 8K, frame rate: $0.4608 / second of input video
- 2K, pro, frame rate: $0.576 / second of input video
- 6K, pro: $0.737 / second of input video

The full example input below costs $0.072 = 72 API credits (10 s input video × $0.0072 (1080p)).

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/bytedance-upscaler/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.

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `video_url` | `video` | string (video URL) | yes |  |  | URL اشاره‌کننده به ویدیوی منبع برای بزرگ‌نمایی. |
| `target_resolution` |  | enum (string) | no | `1080p` | `1080p`, `2k`, `4k`, `6k`, `8k` | وضوح مطلوب برای ویدیوی بزرگ‌شده. |
| `target_fps` |  | number | no | `30` | 24 – 120 | نرخ فریم مطلوب برای خروجی بهبودیافته، برحسب فریم بر ثانیه. |
| `enhancement_preset` |  | enum (string) | no | `general` | `general`, `ugc`, `short_series`, `aigc`, `old_film` | پیش‌تنظیم بهبود متناسب با نوع ویدیو. برای پردازش عمومی از 'general'، برای ویدیوهای کوتاه تولیدشده توسط کاربر از 'ugc'، برای درام‌های کوتاه از 'short_series'، برای محتوای تولیدشده با هوش مصنوعی از 'aigc' و برای ترمیم فیلم‌های کلاسیک از 'old_film' استفاده کنید. |
| `enhancement_tier` |  | enum (string) | no | `standard` | `fast`, `standard`, `pro` | سطح کیفیت استفاده‌شده برای بهبود. |
| `scale_ratio` |  | number \| null | no |  | 1.1 – 10 | ضریب وضوح خروجی، از 1.1 تا 10.0؛ در صورت ارائه، جایگزین target_resolution می‌شود و وضوح ورودی را ضرب می‌کند (برای مثال، 2.0 آن را دو برابر می‌کند). مقیاس‌دهی فقط تا 4k پشتیبانی می‌شود که به‌صورت مجموع پیکسل 3840x2160 تعریف شده است؛ عبور از این حد خطا ایجاد می‌کند. |
| `fidelity` |  | enum (string) | no | `high` | `high`, `medium` | شدت بهبود، با 'medium' برای بهبود متعادل کیفیت تصویر یا 'high' برای بهبود ملایمی که بافت بصری ویدیوی منبع را تا حد زیادی حفظ می‌کند. |
| `bit_depth` |  | enum (integer) | no | `8` | `8`, `10`, `12` | عمق بیت رنگ ویدیوی خروجی را انتخاب کنید؛ برای خروجی 10-bit یا 12-bit، رده بهبود Pro لازم است. |

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.com/v1/run/bytedance-upscaler/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.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/bytedance-upscaler/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.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/bytedance-upscaler/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.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": "bytedance-upscaler/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.
