|
|
|
Normalize video audio volume to the EBU R128 broadcast loudness standard.
|
|
|
|
## API Endpoint
|
|
|
|
`POST /api/v1/tools/video/video-loudnorm`
|
|
|
|
Accepts multipart form data with a video file. This tool has no configurable settings.
|
|
|
|
## Parameters
|
|
|
|
This tool has no parameters. It applies EBU R128 loudness normalization to the audio track.
|
|
|
|
## Example Request
|
|
|
|
```bash
|
|
curl -X POST http://localhost:1349/api/v1/tools/video/video-loudnorm \
|
|
-H "Authorization: Bearer si_your-api-key" \
|
|
-F "file=@clip.mp4"
|
|
```
|
|
|
|
## Example Response
|
|
|
|
```json
|
|
{
|
|
"jobId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
|
|
"downloadUrl": "/api/v1/download/a1b2c3d4-e5f6-7890-abcd-ef1234567890/clip.mp4",
|
|
"originalSize": 12500000,
|
|
"processedSize": 12500000
|
|
}
|
|
```
|
|
|
|
## Notes
|
|
|
|
- Uses FFmpeg's `loudnorm` filter targeting -16 LUFS integrated loudness with -1.5 dBTP true peak and 11 LU loudness range (EBU R128 broadcast standard).
|
|
- The source audio sample rate is preserved in the output.
|
|
- If the video has no audio track, the request returns a 400 error.
