## API Information

This model can be used via our HTTP API or more conveniently via our client libraries.
See the input and output schema below, as well as the usage examples.


### Input Schema

The API accepts the following input parameters:


- **`prompt`** (`string`, _required_):
  Text prompt describing how to edit the source video.
  - Examples: "Restyle the footage as a hand-painted watercolor animation with soft pastel colors."

- **`video_url`** (`string`, _required_):
  URL of the source video to edit.
  - Examples: "https://storage.googleapis.com/falserverless/example_inputs/birefnet-video-input.mp4"

- **`start_image_url`** (`string`, _optional_):
  Optional URL of an image to use as the edited video's first frame — e.g. a restyled version of the source's opening frame to steer the look of the edit. Leave unset to let the model derive the first frame from the source video.
  - Examples: "https://storage.googleapis.com/falserverless/gallery/example_inputs_liuyifei.png"

- **`resolution`** (`ResolutionEnum`, _optional_):
  Resolution of the edited video. Higher resolutions cost more. Default value: `"540p"`
  - Default: `"540p"`
  - Options: `"540p"`, `"720p"`, `"1080p"`

- **`duration`** (`DurationEnum`, _optional_):
  Duration of the edited video. Default value: `"5s"`
  - Default: `"5s"`
  - Options: `"5s"`, `"10s"`

- **`edit_strength`** (`Enum`, _optional_):
  How closely the edit preserves the source video. 'adhere_*' stays closest to the source, 'flex_*' is balanced, and 'reimagine_*' diverges most. Leave unset to use Luma's default. Cannot be combined with auto_controls.
  - Options: `"adhere_1"`, `"adhere_2"`, `"adhere_3"`, `"flex_1"`, `"flex_2"`, `"flex_3"`, `"reimagine_1"`, `"reimagine_2"`, `"reimagine_3"`

- **`auto_controls`** (`boolean`, _optional_):
  Let the model derive the edit conditioning schedule from the source video. Cannot be combined with edit_strength.
  - Default: `false`

- **`hdr`** (`boolean`, _optional_):
  Generate an HDR-encoded MP4. Requires HDR access on the account and a resolution of 720p or 1080p.
  - Default: `false`

- **`exr_export`** (`boolean`, _optional_):
  Also export an EXR file alongside the MP4. Requires hdr=true and HDR access.
  - Default: `false`



**Required Parameters Example**:

```json
{
  "prompt": "Restyle the footage as a hand-painted watercolor animation with soft pastel colors.",
  "video_url": "https://storage.googleapis.com/falserverless/example_inputs/birefnet-video-input.mp4"
}
```

**Full Example**:

```json
{
  "prompt": "Restyle the footage as a hand-painted watercolor animation with soft pastel colors.",

  "resolution": "540p",
  "duration": "5s"
}
```


### Output Schema

The API returns the following output format:

- **`video`** (`File`, _required_):
  The generated video.

- **`exr_file`** (`File`, _optional_):
  The generated EXR sidecar when exr_export is true. This may be a single EXR file or a ZIP package depending on Luma's export shape.



**Example Response**:

```json
{
  "video": {
    "url": "",
    "content_type": "image/png",
    "file_name": "z9RV14K95DvU.png",
    "file_size": 4404019
  }

```


## Usage Examples

### cURL

```bash
curl --request POST \
  --url https://fal.run/luma/agent/ray/v3.2/video-to-video \
  --header "Authorization: Key $FAL_KEY" \
  --header "Content-Type: application/json" \
  --data '{
     "prompt": "Restyle the footage as a hand-painted watercolor animation with soft pastel colors.",
     "video_url": "https://storage.googleapis.com/falserverless/example_inputs/birefnet-video-input.mp4"
   }'
```

### Python

Ensure you have the Python client installed:

```bash
pip install fal-client
```

Then use the API client to make requests:

```python
import fal_client

def on_queue_update(update):
    if isinstance(update, fal_client.InProgress):
        for log in update.logs:
           print(log["message"])

result = fal_client.subscribe(
    "luma/agent/ray/v3.2/video-to-video",
    arguments={
        "prompt": "Restyle the footage as a hand-painted watercolor animation with soft pastel colors.",
        "video_url": "https://storage.googleapis.com/falserverless/example_inputs/birefnet-video-input.mp4"
    },
    with_logs=True,
    on_queue_update=on_queue_update,
)
print(result)
```

### JavaScript

Ensure you have the JavaScript client installed:

```bash
npm install --save @fal-ai/client
```

Then use the API client to make requests:

```javascript
import { fal } from "@fal-ai/client";

const result = await fal.subscribe("luma/agent/ray/v3.2/video-to-video", {
  input: {
    prompt: "Restyle the footage as a hand-painted watercolor animation with soft pastel colors.",
    video_url: "https://storage.googleapis.com/falserverless/example_inputs/birefnet-video-input.mp4"
  },
  logs: true,
  onQueueUpdate: (update) => {
    if (update.status === "IN_PROGRESS") {
      update.logs.map((log) => log.message).forEach(console.log);
    }
  },
});
console.log(result.data);
console.log(result.requestId);
```
