# Kling Video · v3 · Pro · Motion Control API

> Prenos gibanja ravni Pro, ki gibe lika iz referenčnega videoposnetka uporabi na sliki lika

Združi sliko lika v `image_url` z gibi iz referenčnega videoposnetka v `video_url`. `character_orientation` je obvezen in določa, ali usmerjenost sledi sliki ali videoposnetku. Podprt je neobvezen `prompt` z največ 2500 znaki, `keep_original_sound` ohrani referenčni zvok, en obrazni element pa je mogoče povezati prek `elements` za pomoč pri ohranjanju identitete.

- 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/sl/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` |  | Varnostna preverjanja je mogoče onemogočiti samo z avtorizacijo računa; zahteve brez avtorizacije so vedno preverjene. |
| `prompt` |  | string \| null | no |  | ≤ 2500 characters |  |
| `image_url` | `image` | string (image URL) | yes |  |  | URL referenčne slike za generiranje videa, z omejitvijo velikosti datoteke 10.0MB, širino in višino med 340px in 3850px ter razmerjem stranic med 0.40 in 2.50. Ta slika usmerja like, ozadja in druge elemente videa. Pri likih zagotovite jasna telesna razmerja, brez zakrivanja, ter pokritost več kot 5% površine slike. |
| `video_url` | `video` | string (video URL) | yes |  |  | URL videa, katerega gibi lika usmerjajo izhod; prikazovati mora neoviran lik v realističnem slogu, z vidno glavo in celotnim ali zgornjim delom telesa. Nastavitev character_orientation omejuje trajanje na 10s za 'image' oziroma 30s za 'video'. Omejitve datoteke: največ 100 MB, širina in višina med 340px in 3850px ter trajanje med 3.0s in 30.05s. |
| `keep_original_sound` |  | boolean | no | `true` |  | Določa, ali se ohrani izvirni zvok referenčnega videa. |
| `character_orientation` |  | enum (string) | yes |  | `image`, `video` | Vir usmerjenosti lika: 'image' se ujema z referenčno sliko in je primernejši za sledenje premikom kamere, največ 10 sekund. Za zapletene gibe je primernejši 'video': ujema se z usmerjenostjo referenčnega videa in omogoča do 30 sekund. |
| `elements` |  | array of object {frontal_image_url, reference_image_urls} \| null | no |  |  | Izbirna vezava obraznega elementa za boljše ohranjanje identitete v izhodnem videu, omejena na 1 naloženi element. V pozivu ga naslovite z @Element1. Vezava je na voljo samo, če je character_orientation nastavljen na 'video'. |
| `elements[].frontal_image_url` |  | string (image URL) \| null | no |  |  | Čelna slika glavnega pogleda elementa. Velikost datoteke ne sme presegati 50 MB; širina in višina morata biti dolgi najmanj 300px, razmerje stranic pa mora biti med 0.40 in 2.50. |
| `elements[].reference_image_urls` |  | array of image URL \| null | no |  |  | Posredujte 1–3 dodatne referenčne slike z različnimi koti. Vsaka slika mora imeti razmerje stranic med 0.40 in 2.50, obe dimenziji dolgi najmanj 300px in velikost največ 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

```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 request = await res.json();
if (!res.ok) throw new Error(request.error.code + ": " + request.error.message);

  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 = {
    "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 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.
