# ID-V2V Relight API

> Yeniden ışıklandırılmış bir referans karenin ışıklandırmasını klip boyunca yayan video yeniden ışıklandırma

Kaynak videonun (`video_url`) aydınlatmasını, yeniden aydınlatılmış ilk kareyi (`image_url`) ve bir `prompt` değerini kullanarak değiştirir; sahneyi ve performansı korur. En fazla 5 `keyframes` sabitlenebilir. Çözünürlük 480p veya 720p'dir, `num_frames` 17-241 arasındadır ve `vace_scale` (0-2), kaynak yapının çıktıyı ne kadar sıkı kısıtlayacağını belirler. Segmentasyon istemi sunulmaz.

- Model id: `id-v2v/relight`
- Made by: Open model
- Category: Video to Video
- Output: video
- Price per second of your output video: $0.20 / second of output video (cheapest run $0.20 (200 API credits))
- Run: `POST https://api.doitong.com/v1/run/id-v2v/relight`
- Quote: `POST https://api.doitong.com/v1/quote/id-v2v/relight`
- Docs page: https://doitong.com/tr/developers/models/id-v2v/relight

## Pricing

Price: **$0.20 / second of output video**. Price per second of your output 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 $1.013 = 1013 API credits (5.0625 s output video × $0.20).

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/id-v2v/relight` 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 |
|---|---|---|---|---|---|---|
| `prompt` |  | string | yes |  |  | İstenen yeniden stillendirilmiş videoyu belirten istem. |
| `video_url` | `video` | string (video URL) | yes |  |  | Üretim için kaynak video URL'si olarak sağlanan hareket ve kadraj referansı. |
| `image_url` | `image` | string (image URL) | yes |  |  | Yeniden stillendirilmiş ilk kareye işaret eden URL olarak sağlanan, video yeniden üretimi için kimlik ve stil referansı. |
| `keyframes` |  | array of object {image_url, frame_index} | no |  | ≤ 5 items | Uzun videolar için isteğe bağlı kimlik sabitleyicileri: yeniden stillendirilmiş ana kareleri, görünmeleri gereken çıktı kare dizinleriyle birlikte sağlayın. |
| `keyframes[].image_url` |  | string (image URL) | yes |  |  | Uzun videodaki kimlik sabitleyicisi için yeniden stillendirilmiş görsel URL'si; görselin en-boy oranı çıktınınkinden en fazla 0.1 farklı olmalıdır. Görsel `frame_index` konumunda değişiklik yapılmadan görünür. |
| `keyframes[].frame_index` |  | integer | yes |  | ≥ 1 | Ana kareyi, 0 tabanlı indeksleme kullanarak en az 1 ve çıktının toplam kare sayısından küçük bir çıktı konumuna yerleştirin. 0 konumu, `image_url` adresindeki yeniden stillendirilmiş başlangıç karesi için ayrılmıştır. |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `720p` | 1280×720 veya 720×1280 çıktı için 720p, 832×480 veya 480×832 çıktı için 480p seçin. Uygulanacak boyutları kaynak videonun yönü belirler. |
| `num_frames` |  | integer | no | `81` | 17 – 241 | Üretilecek kare sayısını sınırlar; kaynak daha az kare içeriyorsa kare sayısı üst sınır olur. |
| `num_inference_steps` |  | integer | no | `30` | 2 – 40 | Her video klibi için difüzyon örnekleme adımı sayısıyla ifade edilen klip kalitesi ve hız denetimi: daha fazla adım kaliteyi artırır ancak daha uzun sürer. |
| `guidance_scale` |  | number | no | `5` | 1 – 10 | İsteme bağlılık ile yaratıcılığı dengeleyen sınıflandırıcısız yönlendirme gücü. |
| `vace_scale` |  | number | no | `1` | 0 – 2 | VACE koşullandırma ölçeğiyle ayarlanan kaynak videoya yapısal bağlılık. |
| `seed` |  | integer \| null | no |  |  | Birden fazla klip üretilirken tüm klipler arasında paylaşılan ve yeniden üretilebilir üretim sağlayan rastgele tohum. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Hem girdilerde hem çıktılarda güvenlik denetimlerini etkinleştirir. |

File parameters (`video`, `image`) 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.com/v1/run/id-v2v/relight?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",
    "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
  }'

# 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"

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",

### 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": "id-v2v/relight",
      "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",
        "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
      },
      "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.
