# Kling Video · v3 · Pro · Motion Control API

> Motion transfer sa Pro tier na naglalapat ng galaw ng character mula sa reference video sa isang character larawan

Pinagsasama ang character larawan sa `image_url` at mga galaw mula sa reference video sa `video_url`. Kinakailangan ang `character_orientation` at pinipili nito kung susunod ang orientation sa larawan o video. Sinusuportahan ang opsyonal na `prompt` na hanggang 2500 character, pinananatili ng `keep_original_sound` ang reference audio, at maaaring i-bind ang isang facial element sa pamamagitan ng `elements` upang makatulong na mapanatili ang identity.

- 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/fil/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` |  | Maaaring i-disable ang safety checks lamang kapag awtorisado ang account; ang mga kahilingang walang awtorisasyon ay palaging sasailalim sa checking. |
| `prompt` |  | string \| null | no |  | ≤ 2500 characters |  |
| `image_url` | `image` | string (image URL) | yes |  |  | URL ng reference na larawan para sa pagbuo ng video, na may limitasyon sa laki ng file na 10.0MB, lapad at taas na 340px hanggang 3850px, at aspect ratio na 0.40 hanggang 2.50. Gumagabay ang larawang ito sa mga character, background, at iba pang element ng video. Para sa mga character, tiyaking malinaw ang proporsyon ng katawan, walang natatakpan, at higit sa 5% ng area ng larawan ang sakop. |
| `video_url` | `video` | string (video URL) | yes |  |  | URL na tumutukoy sa video kung saan gumagabay ang mga kilos ng character sa output; dapat itong magpakita ng unobstructed, realistic-style na character na nakikita ang ulo at alinman sa buong katawan o itaas na bahagi ng katawan. Nililimitahan ng character_orientation setting ang tagal sa 10s para sa 'image' o 30s para sa 'video'. Mga limitasyon ng file: hanggang 100 MB, lapad at taas na 340px hanggang 3850px, at tagal na 3.0s hanggang 30.05s. |
| `keep_original_sound` |  | boolean | no | `true` |  | Kinokontrol kung pananatilihin ang orihinal na tunog ng reference video. |
| `character_orientation` |  | enum (string) | yes |  | `image`, `video` | Source ng character orientation: ang 'larawan' ay tumutugma sa reference larawan at mas mahusay sa pagsunod sa camera movements, na may maximum na 10 segundo. Para sa mas kumplikadong galaw, mas mahusay ang 'video': tumutugma ito sa orientation ng reference video at nagbibigay ng hanggang 30 segundo. |
| `elements` |  | array of object {frontal_image_url, reference_image_urls} \| null | no |  |  | Opsyonal na facial element binding para mapahusay ang identity preservation sa output na video, na limitado sa 1 na-upload na element. Gamitin ang @Element1 para tukuyin ito sa prompt. Available lamang ang binding kapag ang character_orientation ay nakatakda sa 'video'. |
| `elements[].frontal_image_url` |  | string (image URL) \| null | no |  |  | Frontal na larawang nagpapakita ng pangunahing view ng element. Hindi dapat lumampas sa 50 MB ang file; dapat hindi bababa sa 300px ang lapad at taas, at nasa pagitan ng 0.40 at 2.50 ang aspect ratio. |
| `elements[].reference_image_urls` |  | array of image URL \| null | no |  |  | Magbigay ng 1–3 karagdagang reference na larawan na nagpapakita ng iba't ibang anggulo. Dapat nasa pagitan ng 0.40 at 2.50 ang aspect ratio ng bawat larawan, hindi bababa sa 300px ang parehong dimension, at hindi lalampas sa 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",

  "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"
```

# 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.
