# Kling Video · v3 · Pro · Motion Control API

> نقل الحركة ضمن فئة Pro، يطبّق حركة الشخصية في فيديو مرجعي على صورة شخصية

يجمع صورة شخصية في `image_url` مع حركات من فيديو مرجعي في `video_url`. يجب تحديد `character_orientation`، الذي يختار ما إذا كان الاتجاه يتبع الصورة أو الفيديو. يدعم `prompt` اختيارياً حتى 2500 حرف، ويحتفظ `keep_original_sound` بالصوت المرجعي، ويمكن ربط عنصر وجهي واحد عبر `elements` للمساعدة في الحفاظ على الهوية.

- Model id: `kling-video/v3/pro/motion-control`
- Made by: Kling
- Category: Video to Video
- Output: video
- Price per second of your input video: $0.168 / second of input video (cheapest run $0.168 (168 API credits))
- Run: `POST https://api.doitong.com/v1/run/kling-video/v3/pro/motion-control`
- Quote: `POST https://api.doitong.com/v1/quote/kling-video/v3/pro/motion-control`
- Docs page: https://doitong.com/ar/developers/models/kling-video/v3/pro/motion-control

## Pricing

Price: **$0.168 / second of input video**. 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.

The full example input below costs $1.68 = 1680 API credits (10 s input video × $0.168).

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/kling-video/v3/pro/motion-control` 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 |
|---|---|---|---|---|---|---|
| `enable_safety_checker` |  | boolean | no | `true` |  | لا يمكن تعطيل فحوصات الأمان إلا بتفويض الحساب؛ وتخضع الطلبات غير المفوّضة للفحص دائمًا. |
| `prompt` |  | string \| null | no |  | ≤ 2500 characters |  |
| `image_url` | `image` | string (image URL) | yes |  |  | عنوان URL لصورة مرجعية لتوليد الفيديو، بحد أقصى لحجم الملف قدره 10.0MB، وعرض وارتفاع يتراوح كل منهما بين 340px و3850px، ونسبة عرض إلى ارتفاع بين 0.40 و2.50. توجه هذه الصورة شخصيات الفيديو وخلفياته والعناصر الأخرى. بالنسبة إلى الشخصيات، احرص على وضوح نسب الجسم وعدم وجود حجب وتغطية تتجاوز 5% من مساحة الصورة. |
| `video_url` | `video` | string (video URL) | yes |  |  | عنوان URL يشير إلى الفيديو الذي توجه حركات شخصيته المخرج؛ وينبغي أن يعرض شخصية بأسلوب واقعي وغير محجوبة، مع ظهور الرأس والجسم كاملًا أو الجزء العلوي منه. يحد إعداد character_orientation المدة إلى 10s عند استخدام 'image' أو 30s عند استخدام 'video'. حدود الملف: 100 MB كحد أقصى، وعرض وارتفاع بين 340px و3850px لكل منهما، ومدة بين 3.0s و30.05s. |
| `keep_original_sound` |  | boolean | no | `true` |  | يتحكم في الاحتفاظ بالصوت الأصلي للفيديو المرجعي. |
| `character_orientation` |  | enum (string) | yes |  | `image`, `video` | مصدر اتجاه الشخصية: يطابق 'image' الصورة المرجعية، وهو أفضل لمتابعة حركات الكاميرا، بحد أقصى 10 ثوانٍ. للحركات المعقدة، يكون 'video' أفضل: إذ يطابق اتجاه الفيديو المرجعي ويسمح بمدة تصل إلى 30 ثانية. |
| `elements` |  | array of object {frontal_image_url, reference_image_urls} \| null | no |  |  | ربط اختياري لعنصر الوجه لتحسين الحفاظ على الهوية في فيديو المخرج، بحد أقصى عنصر واحد مرفوع. استخدم @Element1 للإشارة إليه في الموجّه. لا يتوفر الربط إلا عند ضبط character_orientation على 'video'. |
| `elements[].frontal_image_url` |  | string (image URL) \| null | no |  |  | صورة أمامية تعرض العرض الرئيسي للعنصر. يجب ألا يتجاوز حجم الملف 50 MB؛ وألا يقل العرض والارتفاع عن 300px لكل منهما، مع نسبة عرض إلى ارتفاع بين 0.40 و2.50. |
| `elements[].reference_image_urls` |  | array of image URL \| null | no |  |  | وفّر 1–3 صور مرجعية إضافية تعرض زوايا مختلفة. يجب أن تتراوح نسبة عرض إلى ارتفاع كل صورة بين 0.40 و2.50، وأن يبلغ كل بُعد 300px على الأقل، وألا يتجاوز الحجم 50.0MB. |

File parameters (`image`, `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
{
  "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
  "video": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
  "character_orientation": "image"
}
```

A fuller example:

```json
{
  "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
  "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
  "character_orientation": "image"
}
```

## 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/kling-video/v3/pro/motion-control?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
    "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
    "character_orientation": "image"
  }'

# 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

### Python

```python
import os
import requests

API = "https://api.doitong.com/v1"

payload = {
    "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/kling-video/v3/pro/motion-control", 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": "kling-video/v3/pro/motion-control",
      "input": {
        "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
        "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
        "character_orientation": "image"
      },
      "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.
