Reconcile every tool page's parameters, defaults, and response shape against the tool's Zod settings schema and executionHint in code. Notable fixes: color-palette (add count + format params, hex output, median-cut algorithm), favicon (add 5 params, was documented as having none), qr-generate (add logoDataUri), convert (add ppm/eps/tga formats), video-loudnorm (-16 LUFS not -14), smart-crop (async 202 not sync 200), images-to-video (1080x1080 square), and several output-filename and behavior-note corrections. Also normalize API endpoint paths to /api/v1/tools/<id> (no modality segment) and standardize curl examples on the Docker API port 1349. Verified with a clean docs build.

# Video Speed
|
|
|
|
Speed up or slow down a video with an option to preserve audio pitch.
|
|
|
|
## API Endpoint
|
|
|
|
`POST /api/v1/tools/video-speed`
|
|
|
|
Accepts multipart form data with a video file and a JSON `settings` field.
|
|
|
|
## Parameters
|
|
|
|
| Parameter | Type | Required | Default | Description |
|
|
|-----------|------|----------|---------|-------------|
|
|
| factor | number | No | `2` | Speed multiplier (0.25-4). Values above 1 speed up, below 1 slow down |
|
|
| keepPitch | boolean | No | `true` | Preserve audio pitch when changing speed |
|
|
|
|
## Example Request
|
|
|
|
```bash
|
|
curl -X POST http://localhost:1349/api/v1/tools/video-speed \
|
|
-H "Authorization: Bearer si_your-api-key" \
|
|
-F "file=@clip.mp4" \
|
|
-F 'settings={"factor": 0.5, "keepPitch": true}'
|
|
```
|
|
|
|
## Example Response
|
|
|
|
```json
|
|
{
|
|
"jobId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
|
|
"downloadUrl": "/api/v1/download/a1b2c3d4-e5f6-7890-abcd-ef1234567890/clip.mp4",
|
|
"originalSize": 12500000,
|
|
"processedSize": 24800000
|
|
}
|
|
```
|
|
|
|
## Notes
|
|
|
|
- A factor of `2` doubles playback speed (halves duration). A factor of `0.5` halves playback speed (doubles duration).
|
|
- When `keepPitch` is `true`, the audio is time-stretched so voices sound natural. When `false`, pitch shifts proportionally with speed.
|
|
- The valid range is 0.25x to 4x.
