# Blur Pad
|
|
|
|
Fit a video into a target aspect ratio by filling the padding area with a blurred, scaled copy of the video instead of solid-color bars.
|
|
|
|
## API Endpoint
|
|
|
|
`POST /api/v1/tools/video/blur-pad`
|
|
|
|
Accepts multipart form data with a video file and a JSON `settings` field.
|
|
|
|
## Parameters
|
|
|
|
| Parameter | Type | Required | Default | Description |
|
|
|-----------|------|----------|---------|-------------|
|
|
| target | string | No | `"16:9"` | Target aspect ratio: `16:9`, `9:16`, `1:1`, `4:3`, `3:4` |
|
|
| blur | number | No | `20` | Gaussian blur sigma for the background (2-50) |
|
|
|
|
## Example Request
|
|
|
|
```bash
|
|
curl -X POST http://localhost:1349/api/v1/tools/video/blur-pad \
|
|
-H "Authorization: Bearer si_your-api-key" \
|
|
-F "file=@clip.mp4" \
|
|
-F 'settings={"target": "16:9", "blur": 30}'
|
|
```
|
|
|
|
## Example Response
|
|
|
|
```json
|
|
{
|
|
"jobId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
|
|
"downloadUrl": "/api/v1/download/a1b2c3d4-e5f6-7890-abcd-ef1234567890/clip.mp4",
|
|
"originalSize": 12500000,
|
|
"processedSize": 14100000
|
|
}
|
|
```
|
|
|
|
## Notes
|
|
|
|
- Higher blur values produce a softer, more abstract background. Lower values keep more detail visible.
|
|
- If the video already matches the target aspect ratio, the file is returned unchanged.
|
|
- For solid-color padding, use the Aspect Pad tool instead.
