# Workflow Utilities Scale Video API

> stretch، pad یا crop موڈز اور کوڈیک و کوالٹی ترتیبات کے ساتھ چوڑائی اور اونچائی کے ذریعے ویڈیو کا سائز تبدیل کرتا ہے

ویڈیو کو ہدف `width` (7680 تک) اور/یا `height` (4320 تک) پر دوبارہ اسکیل کرتا ہے؛ صرف ایک دیے جانے پر دوسرا نسبتِ ابعاد کے مطابق ہوتا ہے۔ `mode` stretch، pad (منتخب رنگ کے ساتھ) یا crop ہو سکتا ہے۔ libx264 یا libx265 کے ساتھ انکوڈ کریں، ultrafast سے slow تک اسپیڈ پری سیٹ اور 0 سے 51 تک `crf` استعمال کریں۔ اصل اور نئی پیمائشیں واپس کرتا ہے۔

- Model id: `workflow-utilities/scale-video`
- Made by: Utility
- Category: Video to Video
- Output: video
- Charged by usage (up to $3.60 per run, typical $0.032; the rest of the hold is refunded): $0.001 / second of processing time (cheapest run $0.032 (32 API credits))
- Run: `POST https://api.doitong.ru/v1/run/workflow-utilities/scale-video`
- Quote: `POST https://api.doitong.ru/v1/quote/workflow-utilities/scale-video`
- Docs page: https://doitong.com/ur/developers/models/workflow-utilities/scale-video

## Pricing

Price: **$0.001 / second of processing time**. Charged by actual usage at $0.001 / second of processing time: up to $3.60 per run (the quote gives the maximum for your input), the rest is refunded automatically after the run. A typical run costs $0.032.

The full example input below holds up to $3.60 = 3600 API credits (up to 3600 s of processing time × $0.001) when it starts; a typical run costs $0.032 (32 API credits).

Prices are the upstream price in USD, paid from the API balance in API credits (1000 API credits = 1 USD). This model is charged by usage: `POST https://api.doitong.ru/v1/quote/workflow-utilities/scale-video` with the same JSON body returns the most the run can cost for that input (`credits`, debited when the run starts); after the run you pay the usage the model reports and the rest is refunded automatically. An input whose maximum would exceed the per-run limit is refused with 422. 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 کے ذریعے scale یا resize کی جانے والی ویڈیو فراہم کریں، height اور width دونوں کے لیے جفت dimensions استعمال کریں تاکہ ویڈیو codec کی ضروریات پوری ہوں۔ |
| `width` |  | integer \| null | no |  | 2 – 7,680 | آؤٹ پٹ width، pixels میں، اکیلے یا height کے ساتھ استعمال کی جا سکتی ہے؛ کم از کم ایک dimension درکار ہے۔ صرف width دینے پر aspect ratio تبدیل کیے بغیر height خودکار طور پر اخذ کی جاتی ہے۔ |
| `height` |  | integer \| null | no |  | 2 – 4,320 | آؤٹ پٹ height، pixels میں، اکیلے یا width کے ساتھ استعمال کی جا سکتی ہے؛ کم از کم ایک dimension درکار ہے۔ صرف height دینے پر aspect ratio تبدیل کیے بغیر width خودکار طور پر اخذ کی جاتی ہے۔ |
| `mode` |  | enum (string) | no | `stretch` | `stretch`, `pad`, `crop` | resize کا طریقہ: `stretch` مطلوبہ dimensions زبردستی نافذ کرتا ہے اور aspect ratio تبدیل کر سکتا ہے۔ `pad` اور `crop` دونوں aspect ratio برقرار رکھتے ہیں: `pad` ویڈیو کو مطلوبہ dimensions کے اندر fit کرتا اور خالی جگہ منتخب کردہ رنگ سے بھرتا ہے (letterboxing/pillarboxing)۔ `crop` مطلوبہ dimensions بھرتا ہے، پھر درست سائز کے لیے مرکز سے crop کرتا ہے۔ |
| `pad_color` |  | enum (string) | no | `black` | `black`, `white`, `red`, `green`, `blue`, `gray` | `pad` mode میں padding کے لیے استعمال ہونے والا رنگ؛ دیگر modes اسے نظرانداز کرتے ہیں۔ |
| `codec` |  | enum (string) | no | `libx264` | `libx264`, `libx265` | encoding codec منتخب کریں: بہتر compression کے لیے libx265 (H.265/HEVC)، یا وسیع compatibility کے لیے libx264 (H.264) استعمال کریں۔ |
| `preset` |  | enum (string) | no | `fast` | `ultrafast`, `fast`, `medium`, `slow` | encoding speed کو کنٹرول کرنے والا preset۔ سست preset منتخب کرنے سے compression بہتر ہوتی ہے، مگر encoding time بڑھتا ہے۔ |
| `crf` |  | integer | no | `18` | 0 – 51 | Constant Rate Factor، جو 0–51 کی range میں quality کنٹرول کرتا ہے؛ زیادہ تر content کے لیے 18 عموماً lossless دکھائی دیتا ہے۔ setting کم کرنے سے quality بہتر مگر فائل سائز بڑا ہوتا ہے۔ |

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/workflow-utilities/scale-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/workflow-utilities/scale-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/workflow-utilities/scale-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": "workflow-utilities/scale-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.
