```

## Commands

### Compress Video
```bash
python scripts/main.py compress video.mp4 --target-mb 10
python scripts/main.py compress video.mp4 --crf 28 --output compressed.mp4
```

### Extract Audio
```bash
python scripts/main.py extract-audio video.mp4 --format mp3
python scripts/main.py extract-audio video.mp4 --format wav --output audio.wav
```

### Resize for Social
```bash
python scripts/main.py resize video.mp4 --format instagram  # 1080x1920 (9:16)
python scripts/main.py resize video.mp4 --format youtube    # 1920x1080 (16:9)
python scripts/main.py resize video.mp4 --format square     # 1080x1080 (1:1)
python scripts/main.py resize video.mp4 --width 1280 --height 720
```

### Clip Segment
```bash
python scripts/main.py clip video.mp4 --start 00:30 --end 01:45
python scripts/main.py clip video.mp4 --start 00:30 --duration 60
```

### Merge Videos
```bash
python scripts/main.py concat video1.mp4 video2.mp4 --output merged.mp4
python scripts/main.py concat ./clips/ --output compilation.mp4
```

### Generate Thumbnail
```bash
python scripts/main.py thumbnail video.mp4 --time 00:30
python scripts/main.py thumbnail video.mp4 --best  # Auto-select best frame
```

## Examples

### Example 1: Prepare Video for Instagram Reels
```bash
# Original: 4K horizontal video, 500MB
python scripts/main.py resize long-video.mp4 --format instagram
python scripts/main.py compress long-video_instagram.mp4 --target-mb 50

# Output: long-video_instagram_compressed.mp4 (1080x1920, <50MB)
```

### Example 2: Extract Podcast from Webinar
```bash
# Extract audio track
python scripts/main.py extract-audio webinar-recording.mp4 --format mp3 --bitrate 192k

# Output: webinar-recording.mp3 (ready for podcast hosting)
```

### Example 3: Create Highlight Reel
```bash
# Extract multiple clips
python scripts/main.py clip interview.mp4 --start 05:30 --end 06:15 --output clip1.mp4
python scripts/main.py clip interview.mp4 --start 12:00 --end 12:45 --output clip2.mp4
python scripts/main.py clip interview.mp4 --start 28:30 --end 29:00 --output clip3.mp4

# Merge into highlight reel
python scripts/main.py concat clip1.mp4 clip2.mp4 clip3.mp4 --output highlights.mp4
```

| Twitter/X | 16:9 | 1920x1080 | 512MB | 2:20 |

## Performance Tips

1. **GPU acceleration** - FFmpeg uses hardware encoding when available (NVENC, VideoToolbox)
2. **CRF values** - Lower = better quality, larger file. 18-28 typical range
3. **Preset selection** - `ultrafast` for drafts, `slow` for final exports
4. **Two-pass encoding** - Better quality for target bitrate
