## Available Options

| Option | Description | Example |
|--------|-------------|---------|
| `--clip <start>-<end>` | **PRIMARY FEATURE** - Clip from start to end time | `--clip 00:30-02:15` |
| `--quality <resolution>` | Specify quality (720p, 1080p, best) | `--quality 1080p` |
| `--audio-only` | Extract audio as MP3 | `--audio-only` |
| `--output <filename>` | Custom output filename | `--output my_clip.mp4` |
| `--format <format>` | Output format (mp4, mkv, webm, mp3) | `--format mkv` |

## Time Format for Clipping

The skill accepts flexible timestamp formats:
- **MM:SS**: `01:30` (1 minute 30 seconds)
- **HH:MM:SS**: `01:15:30` (1 hour 15 minutes 30 seconds)
- **M:SS**: `1:30` (same as 01:30)
- **SS**: `90` (converted to 01:30)

## How Clipping Works

1. You provide a YouTube URL and time range
2. Claude parses your timestamps
3. The skill extracts just that section using optimized methods:
   - **Method 1**: yt-dlp's native clipping (fastest)
   - **Method 2**: ffmpeg precise cutting (fallback)
4. Your clip is saved to the current directory

## Use Cases

## Output Location

All clips and downloads are saved to your current working directory. You can specify a custom path using the `--output` flag.

## Important Notes

- **Pure Python solution** - no binary dependencies, just Python
- **Auto-installs dependencies** - yt-dlp Python module installed automatically if needed
- **Clipping is optimized and fast** - no need to download full videos first
- **Quality is maintained** - clips preserve the original video quality
- **Copyright matters** - only clip content you have rights to access
- **Flexible timestamps** - use whatever format is natural for you
- **Minimal setup** - Python is usually pre-installed, everything else is automatic

## Technical Details

- **Language**: Pure Python implementation
- **Primary Library**: yt-dlp Python module (auto-installed via pip)
- **Audio Processing**: ffmpeg (required for audio extraction, usually pre-installed)
- **Supported Formats**: All standard video and audio formats

## Troubleshooting

### Clip not extracting correctly
