# Video Noise Reduction

Reduce noise, grain, and artifacts from videos using each::sense. This skill handles low light footage, high ISO grain, security camera enhancement, old footage restoration, and various denoising tasks while preserving important details.

## Features

- **Low Light Denoising**: Clean up footage shot in dim conditions
- **High ISO Grain Removal**: Remove digital noise from high sensitivity recordings
- **Security Camera Enhancement**: Improve clarity of surveillance footage
- **Old Footage Restoration**: Restore vintage or degraded video
- **Webcam Quality Improvement**: Enhance video call recordings
- **Night Mode Cleanup**: Fix noisy night vision or low light phone footage
- **Compression Artifact Removal**: Clean up heavily compressed video
- **Film Grain Removal**: Remove unwanted grain from film scans
- **Detail Preservation**: Denoise while maintaining sharpness and texture

## Quick Start

```bash
curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "messages": [{"role": "user", "content": "Denoise this video, reduce the grain while keeping details sharp"}],
    "model": "eachsense/beta",
    "stream": true,
    "mode": "max",
    "video_urls": ["https://example.com/noisy-video.mp4"]
  }'
```

## Denoising Parameters

| Parameter | Description | Use Case |
|-----------|-------------|----------|
| Strength | How aggressively to remove noise | Light for subtle cleanup, heavy for very noisy footage |
| Detail Preservation | Balance between smoothing and sharpness | Higher for footage with important textures |
| Temporal Consistency | Reduce flickering between frames | Essential for video to avoid artifacts |
| Color Denoising | Clean chroma noise separately | Useful for high ISO color noise |
