# Wan2.7-VideoEdit Video Editing

>  - Alibaba Cloud Wanxiang 2.7 video editing model
- AI editing based on existing videos: style transfer, content replacement, element addition
- Optionally accepts reference images to specify target style or appearance
- Supports keeping the original video duration or customizing the output duration

## Use Cases

### Case 1: Basic Video Editing (Simplest)

```json theme={null}
{
  "model": "wan2.7-videoedit",
  "video_urls": ["https://cdn.example.com/original.mp4"],
  "prompt": "Replace the background with a snowy mountain scene"
}
```

### Case 2: Style Transfer (With Reference Image)

```json theme={null}
{
  "model": "wan2.7-videoedit",

    "https://cdn.example.com/anime_style.jpg"
  ],
  "resolution": "1080P",
  "watermark": false
}
```

```json theme={null}
{
  "model": "wan2.7-videoedit",
  "video_urls": ["https://cdn.example.com/speech.mp4"],
  "prompt": "Replace the background with a mountain path",
  "metadata": { "audio_setting": "origin" }
}
```

### Case 4: Full Parameters

```json theme={null}
{
  "model": "wan2.7-videoedit",
  "prompt": "Change the character's outfit to a red gown",
  "negative_prompt": "blurry, distorted",
  "video_urls": ["https://cdn.example.com/original.mp4"],
  "image_urls": ["https://cdn.example.com/reference.jpg"],
  "resolution": "1080P",
  "duration": 0,
  "size": "16:9",
  "prompt_extend": true,
  "watermark": false,
  "seed": 888,
  "metadata": {
    "audio_setting": "origin"
  }
}
```

## Audio Handling

| audio\_setting   | Description                                                     | Suitable Scenarios                                                    |
| ---------------- | --------------------------------------------------------------- | --------------------------------------------------------------------- |
| `auto` (default) | AI regenerates matching audio based on the edited video content | Major visual style changes where you want audio to update accordingly |
| `origin`         | Force keep the original video audio track                       | Videos with important background music or dialogue                    |

<Note>
  **Query Task Results**

  Video generation is an async task that returns a `task_id` upon submission. Use the [Get Task Status](/en/api-reference/tasks/status) endpoint to query generation progress and results.
