# Wan 2.2 Reframe — API Reference

Model ID: `model_wan-2-2-vace-fun-a14b-reframe`

---

## Authentication

Scenario API uses HTTP Basic Auth. Encode your credentials in Base64 and pass them as the `Authorization` header.

```
Authorization: Basic base64("<API_KEY>:<API_SECRET>")
```

- **API_KEY** and **API_SECRET** are found in your [Scenario Project Settings](https://app.scenario.com/team&tab=project_api_keys) under API Keys.
- In shell: `$(echo -n '<API_KEY>:<API_SECRET>' | base64)`
- In JavaScript: `btoa("<API_KEY>:<API_SECRET>")`
- In Python: `base64.b64encode(f"{api_key}:{api_secret}".encode()).decode()`

## Generate

**Endpoint:** `POST https://api.cloud.scenario.com/v1/generate/custom/model_wan-2-2-vace-fun-a14b-reframe`

### Parameters

| Parameter | Type | Required | Default | Description |
|-----------|------|----------|---------|-------------|
| `prompt` | string | - | - | Text prompt for video generation |
| `negativePrompt` | string | - | - | Text negative prompt for video generation |
| `matchInputNumFrames` | boolean | - | `false` | Match the number of frames from input video |
| `numFrames` | number | - | `81` | Number of frames to generate |
| `matchInputFramesPerSecond` | boolean | - | `false` | If true, the frames per second of the generated video will match the input video. If false, the frames per second will be determined by the Frames Per Seconds parameter. |
| `framesPerSecond` | number | - | `16` | Frames per second of the generated video. Ignored if match_input_frames_per_second is true. Default value: 16 |
| `resolution` | string | - | `720p` | Output video resolution |
| `aspectRatio` | string | - | `auto` | Aspect ratio for output video |
| `numInferenceSteps` | number | - | `30` | Number of inference steps |
| `guidanceScale` | number | - | `5` | Guidance scale for generation |
| `enablePromptExpansion` | boolean | - | `false` | Enable prompt expansion |
| `acceleration` | string | - | `regular` | Processing acceleration mode |
| `videoQuality` | string | - | `high` | Output video quality |
| `videoWriteMode` | string | - | `balanced` | Video writing mode |
| `numInterpolatedFrames` | number | - | `1` | Number of frames to interpolate between the original frames. A value of 0 means no interpolation |
| `interpolatorModel` | string | - | `film` | Interpolator model to use |
| `zoomFactor` | number | - | `0` | Zoom factor for the video. When this value is greater than 0, the video will be zoomed in by this factor (in relation to the canvas size,) cutting off the edges of the video. A value of 0 means no zoom. |
| `trimBorders` | boolean | - | `true` | Whether to trim borders from the video. |
| `temporalDownsampleFactor` | number | - | `0` | Temporal downsample factor for the video. This is an integer value that determines how many frames to skip in the video. A value of 0 means no downsampling. For each downsample factor, one upsample factor will automatically be applied. |
| `seed` | number | - | - | Random seed for reproducibility. If None, a random seed is chosen. |

## Retrieve Results

After submitting a generation request, you receive a `jobId`. Poll the job status endpoint until the job completes.

**Endpoint:** `GET https://api.cloud.scenario.com/v1/jobs/{jobId}`

**Headers:**
```
Authorization: Basic base64("<API_KEY>:<API_SECRET>")
```

Poll until `job.status` is `"success"`. The generated asset IDs are in `job.metadata.assetIds`.

**Example response:**
```json
{
  "job": {
    "jobId": "job_abc123",
    "status": "success",
    "metadata": {
      "assetIds": [
        "asset_abc123"
      ]
    }
  }
}
```

> **Important:** Generated asset URLs are **temporary** and expire after a short period. Download and store any images you wish to keep before the URL expires. More info: [Content Delivery Network (CDN)](https://docs.scenario.com/docs/content-delivery-network-cdn).
