# Trim Video
|
|
|
|
Cut a clip out of a video by specifying start and end times in seconds, with an option for frame-accurate cuts.
|
|
|
|
## API Endpoint
|
|
|
|
`POST /api/v1/tools/video/trim-video`
|
|
|
|
Accepts multipart form data with a video file and a JSON `settings` field.
|
|
|
|
## Parameters
|
|
|
|
| Parameter | Type | Required | Default | Description |
|
|
|-----------|------|----------|---------|-------------|
|
|
| startS | number | No | `0` | Start time in seconds (must be >= 0) |
|
|
| endS | number | Yes | - | End time in seconds (must be after startS) |
|
|
| precise | boolean | No | `false` | Re-encode for frame-accurate cuts instead of keyframe seek |
|
|
|
|
## Example Request
|
|
|
|
```bash
|
|
curl -X POST http://localhost:1349/api/v1/tools/video/trim-video \
|
|
-H "Authorization: Bearer si_your-api-key" \
|
|
-F "file=@clip.mp4" \
|
|
-F 'settings={"startS": 5, "endS": 30, "precise": true}'
|
|
```
|
|
|
|
## Example Response
|
|
|
|
```json
|
|
{
|
|
"jobId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
|
|
"downloadUrl": "/api/v1/download/a1b2c3d4-e5f6-7890-abcd-ef1234567890/clip.mp4",
|
|
"originalSize": 12500000,
|
|
"processedSize": 4200000
|
|
}
|
|
```
|
|
|
|
## Notes
|
|
|
|
- When `precise` is `false` (the default), the tool uses keyframe seeking, which is fast but may start a few frames before the requested time.
|
|
- Setting `precise` to `true` re-encodes the segment for exact frame boundaries, but takes longer.
|
|
- The `endS` value must be greater than `startS`.
