# Rotate Video
Rotate a video by 90, 180, or 270 degrees, or flip it horizontally or vertically.
## API Endpoint

Accepts multipart form data with a video file and a JSON `settings` field.
## Parameters
| Parameter | Type | Required | Default | Description |

| transform | string | Yes | - | Transformation to apply: `cw90`, `ccw90`, `180`, `hflip`, `vflip` |
### Transform Values

- **180** - Rotate 180 degrees
- **hflip** - Flip horizontally (mirror)

## Example Request
```bash
curl -X POST http://localhost:1349/api/v1/tools/video/rotate-video \

```
## Example Response

{
"jobId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
"downloadUrl": "/api/v1/download/a1b2c3d4-e5f6-7890-abcd-ef1234567890/clip.mp4",
"originalSize": 12500000,
"processedSize": 12400000

## Notes
- Rotations by 90 or 270 degrees swap the video's width and height.
- Flip operations (hflip, vflip) do not change the video dimensions.
