# Kling O3 Edit Video [Pro] API

> O3-videoredigering på Pro-niveau, der omskriver et inputklip ud fra en prompt med billed- og elementreferencer

Redigerer en eksisterende video efter en tekstprompt, der henviser til kilden som @Video1. `video_url` skal være .mp4 eller .mov, 3-15 sekunder lang, 720-3840px og højst 200MB. Referencebilleder (`image_urls`) og `elements` kan nævnes i prompten, højst 4 i alt. `keep_audio` bevarer det oprindelige lydspor og er aktiveret som standard.

- Model id: `kling-video/o3/pro/video-to-video/edit`
- 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.ru/v1/run/kling-video/o3/pro/video-to-video/edit`
- Quote: `POST https://api.doitong.ru/v1/quote/kling-video/o3/pro/video-to-video/edit`
- Docs page: https://doitong.com/da/developers/models/kling-video/o3/pro/video-to-video/edit

## 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.ru/v1/quote/kling-video/o3/pro/video-to-video/edit` 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` |  | Sikkerhedstjek kan kun deaktiveres med kontogodkendelse; anmodninger uden godkendelse bliver altid kontrolleret. |
| `prompt` |  | string | yes |  | ≤ 2500 characters | Tekstinstruktioner til generering af videoen. Brug @Video1 til at referere til referencevideoen. |
| `video_url` | `video` | string (video URL) | yes |  |  | URL, der peger på en referencevideo i .mp4- eller .mov-format, højst 200MB. Begge dimensioner skal være mellem 720px og 3840px, med en billedhastighed på 23.0–60.0 FPS og en varighed på 3–15 sekunder (højst 15.05 sekunder). |
| `image_urls` | `images` | array of image URL \| null | no |  |  | Billeder, der styrer stil eller udseende, adresseret i prompten med @Image1, @Image2 osv. Ved videoinput må elementer og referencebilleder tilsammen ikke overstige 4 elementer. Hver fil er begrænset til 50 MB, med bredde og højde på mindst 300 px og et formatforhold fra 0.40 til 2.50. |
| `keep_audio` |  | boolean | no | `true` |  | Styrer, om referencevideoens oprindelige lyd bevares. |
| `elements` |  | array of object {frontal_image_url, reference_image_urls} \| null | no |  |  | Figurer eller objekter, der skal medtages, adresseret i prompten med @Element1 og @Element2. |
| `elements[].frontal_image_url` |  | string (image URL) \| null | no |  |  | Frontalt billede, der viser elementets primære visning. Filstørrelsen må ikke overstige 50 MB; bredde og højde skal hver være mindst 300px, med et formatforhold mellem 0.40 og 2.50. |
| `elements[].reference_image_urls` |  | array of image URL \| null | no |  |  | Angiv 1–3 ekstra referencebilleder, der viser forskellige vinkler. Hvert billede skal have et formatforhold mellem 0.40 og 2.50, måle mindst 300px i begge dimensioner og højst være 50.0MB. |
| `shot_type` |  | string | no | `customize` |  | Tilstand brugt til at generere videoer med flere optagelser. |

File parameters (`video`, `images`) 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
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
  "video": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
}
```

A fuller example:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
  "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/kling-video/o3/pro/video-to-video/edit?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
    "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/kling-video/o3/pro/video-to-video/edit?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
    "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 = {
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
    "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/kling-video/o3/pro/video-to-video/edit", 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": "kling-video/o3/pro/video-to-video/edit",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
        "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.
