# Luma Ray 3.2 Video to Video API

> 編集強度プリセット、制御、キーフレームに対応し、入力動画のスタイルを変更するRay 3.2動画編集

`prompt`に従って`video_url`を編集し、任意の`start_image_url`で最初のフレームを誘導できます。`edit_strength`はadhere、flex、reimagineのレベル1～3に対応し、`auto_controls`または`controls`オブジェクトで別の条件付けを指定できます。最大64個の`keyframes`を`keyframe_indexes`で固定できます。出力は540p～1080p、5sまたは10sで、`hdr`と`exr_export`を任意で使用できます。

- Model id: `luma/agent/ray/v3.2/video-to-video`
- Made by: Luma AI
- Category: Video to Video
- Output: video
- Price: from $0.144 / second (5 s ≈ $0.72) (cheapest run $0.72 (720 API credits))
- Run: `POST https://api.doitong.ru/v1/run/luma/agent/ray/v3.2/video-to-video`
- Quote: `POST https://api.doitong.ru/v1/quote/luma/agent/ray/v3.2/video-to-video`

## Pricing

Price: **from $0.144 / second (5 s ≈ $0.72)** (the lowest tier; the quote prices your exact input). Billed per second of output (`duration`, default 10).

Price rules (the first rule that matches the input wins; a parameter you leave out counts as its default):

- When `exr_export` = true and `hdr` = true and `resolution` = 1080p: $1.296 (1296 API credits) / second
- When `exr_export` = true and `hdr` = true: $0.648 (648 API credits) / second
- When `hdr` = true and `resolution` = 1080p: $0.864 (864 API credits) / second
- When `hdr` = true: $0.432 (432 API credits) / second
- When `resolution` = 1080p: $0.432 (432 API credits) / second
- When `resolution` = 720p: $0.216 (216 API credits) / second

The full example input below costs $0.72 = 720 API credits (5 s × 144 API credits).

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/luma/agent/ray/v3.2/video-to-video` 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 |  | 1 – 6000 characters | ソース動画を編集するためのテキスト指示。 |
| `video_url` | `video` | string (video URL) | yes |  | ≥ 1 characters | 編集対象動画のURL。 |
| `user` |  | string \| null | no |  |  | リクエストを送信するエンドユーザーを識別する任意の不透明ID。 |
| `start_image_url` | `image` | string (image URL) \| null | no |  |  | 編集動画の先頭フレームの上書き。任意の画像URLで指定します。省略すると、モデルがソース動画からそのフレームを導出します。例えば、ソースからスタイルを変更した開始画像を指定すると、編集の外観を導けます。 |
| `resolution` |  | enum (string) | no | `540p` | `540p`, `720p`, `1080p` | 編集後の出力解像度。 |
| `duration` |  | enum (string) | no | `5s` | `5s`, `10s` | 編集後の動画の長さ。 |
| `edit_strength` |  | enum (string) \| null | no |  | `adhere_1`, `adhere_2`, `adhere_3`, `flex_1`, `flex_2`, `flex_3`, `reimagine_1`, `reimagine_2`, `reimagine_3` | 編集におけるソース保持設定。auto_controlsを使用しない場合のみ利用できます。省略するとモデルのデフォルトを選択します。変更量が大きい順から、'reimagine_*'、バランスの取れた結果の'flex_*'、'adhere_*'が選択肢です。 |
| `auto_controls` |  | boolean | no | `false` |  | 自動編集条件付け。モデルはこのオプションとともにedit_strengthを受け取るのではなく、ソース動画からスケジュールを決定します。 |
| `hdr` |  | boolean | no | `false` |  | 720pまたは1080pのMP4出力用HDRエンコード。HDRアクセス権を持つアカウントのみ利用できます。 |
| `exr_export` |  | boolean | no | `false` |  | MP4に付随する追加のEXRエクスポート。HDRアクセス権とhdr=trueの両方がある場合にのみ利用できます。 |
| `controls` |  | object {pose, depth, normals, trajectory, face} \| null | no |  |  | edit_strengthの詳細な代替機能。ポーズ、深度、法線、軌跡、顔ごとに条件付けを設定します。これらの制御を使用するとauto_controlsは利用できません。 |
| `controls.pose` |  | object {enabled, strength} \| null | no |  |  | ポーズまたはスケルトンに基づく条件付け。 |
| `controls.pose.enabled` |  | boolean | no | `true` |  | 編集時のポーズまたはスケルトン条件付けの切り替え。 |
| `controls.pose.strength` |  | enum (string) \| null | no |  | `precise`, `coarse` | ポーズ条件付けの精度選択。省略するとデフォルトを維持し、自由度を高めるには'coarse'、ソースのポーズを厳密に追跡するには'precise'を選択します。 |
| `controls.depth` |  | object {enabled, blur} \| null | no |  |  | 深度またはシーン形状に基づく条件付け。 |
| `controls.depth.enabled` |  | boolean | no | `true` |  | 編集時の深度またはシーン形状条件付けの切り替え。 |
| `controls.depth.blur` |  | number \| null | no |  | 0 – 1 | 深度ぼかし設定。未指定ではデフォルトを維持し、値を大きくすると形状の自由度が高まります。 |
| `controls.normals` |  | object {enabled, augmentation} \| null | no |  |  | サーフェス法線に基づく条件付け。 |
| `controls.normals.enabled` |  | boolean | no | `true` |  | 編集時のサーフェス法線条件付けの切り替え。 |
| `controls.normals.augmentation` |  | number \| null | no |  | 0 – 1 | サーフェス法線の拡張設定。省略するとデフォルトを維持し、値を大きくするとサーフェス形状の再解釈を許可します。 |
| `controls.trajectory` |  | object {enabled, sparsity} \| null | no |  |  | 動作軌跡に基づく条件付け。 |
| `controls.trajectory.enabled` |  | boolean | no | `true` |  | 編集時の動作軌跡条件付けの切り替え。 |
| `controls.trajectory.sparsity` |  | number \| null | no |  | 0 – 1 | 動作軌跡の疎性設定。省略するとデフォルトを維持し、値を大きくすると使用する動作アンカー数を減らします。 |
| `controls.face` |  | object {enabled} \| null | no |  |  | 顔の同一性に基づく条件付け。 |
| `controls.face.enabled` |  | boolean | no | `true` |  | 編集時の顔の同一性条件付けの切り替え。 |
| `keyframes` |  | array of string \| null | no |  | 1 – 64 items | start_image_urlの代わりに画像URLで指定するマルチキーフレーム編集ガイド。キーフレームを同じ長さのkeyframe_indexes配列とともに指定し、各画像をソース動画のフレーム位置に固定します。URLは最大64個です。 |
| `keyframe_indexes` |  | array of integer \| null | no |  | 1 – 64 items | キーフレームに1対1で対応するソースフレームのマッピング。entry [i]はkeyframes[i]のアンカー位置を指定します。両方の配列は同じ長さで、位置は重複しない非負値である必要があります。 |
| `enable_safety_checker` |  | boolean | no | `true` |  | 呼び出し元に権限がある場合、false に設定するとスクリーニングを緩和できます。 |

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"

}
```

## 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/luma/agent/ray/v3.2/video-to-video?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"
```

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/luma/agent/ray/v3.2/video-to-video", 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": "luma/agent/ray/v3.2/video-to-video",
      "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.
