# Wan2VideoEditApi Node Documentation

The Wan2VideoEditApi node uses the Wan 2.7 model to edit a video based on text instructions, reference images, or style transfer. It processes the input video and generates a new video according to the specified parameters like resolution, duration, and aspect ratio.

## Inputs

| Parameter | Description | Data Type | Required | Range |
|-----------|-------------|-----------|----------|-------|
| `model` | The model to use for video editing. | COMBO | Yes | `"wan2.7-videoedit"` |
| `model.prompt` | Editing instructions or style transfer requirements. (default: empty string) | STRING | Yes | - |
| `model.resolution` | The resolution for the output video. | COMBO | Yes | `"720P"`<br>`"1080P"` |
| `model.ratio` | The aspect ratio for the output video. If not changed, it approximates the input video's ratio. | COMBO | Yes | `"16:9"`<br>`"9:16"`<br>`"1:1"`<br>`"4:3"`<br>`"3:4"` |
| `model.duration` | The output duration in seconds. 'auto' matches the input video duration. A specific value truncates from the start of the video. (default: "auto") | COMBO | Yes | `"auto"`<br>`"2"`<br>`"3"`<br>`"4"`<br>`"5"`<br>`"6"`<br>`"7"`<br>`"8"`<br>`"9"`<br>`"10"` |
| `model.reference_images` | A list of up to 4 reference images to guide the edit. | IMAGE | No | - |
| `video` | The video to edit. | VIDEO | Yes | - |
| `seed` | The seed to use for generation. (default: 0) | INT | No | 0 to 2147483647 |
| `audio_setting` | 'auto': model decides whether to regenerate audio based on the prompt. 'origin': preserve the original audio from the input video. (default: "auto") | COMBO | No | `"auto"`<br>`"origin"` |
| `watermark` | Whether to add an AI-generated watermark to the result. (default: False) | BOOLEAN | No | - |

**Constraints:**
*   The `model.prompt` must be at least 1 character long.
*   The input `video` must be between 2 and 10 seconds in duration.
*   The `model.reference_images` input can accept a maximum of 4 images.

## Outputs

| Output Name | Description | Data Type |
|-------------|-------------|-----------|
| `output` | The edited video generated by the model. | VIDEO |
