## List Available Formats

Before downloading, check what formats are available:

```bash
yt-dlp -F "URL"
```

This shows all available video and audio streams with:
- Format ID
- Extension
- Resolution
- FPS
- Codec
- File size
- Bitrate

Then download specific format:
```bash
yt-dlp -f FORMAT_ID "URL"
```

## Batch Download

### From File
Create a text file with URLs (one per line):
```
https://www.youtube.com/watch?v=VIDEO1
https://www.youtube.com/watch?v=VIDEO2
https://www.youtube.com/watch?v=VIDEO3
```

Download all:
```bash
yt-dlp -a urls.txt
```

### With Archive
Track downloaded videos to avoid re-downloading:
```bash
yt-dlp --download-archive archive.txt "PLAYLIST_URL"
```

This creates `archive.txt` with IDs of downloaded videos. On subsequent runs, yt-dlp skips already downloaded videos.

## Filtering and Selection

### Date Filters
```bash
# Videos from 2024
yt-dlp --dateafter 20240101 "CHANNEL_URL"

# Videos before 2023

yt-dlp --dateafter 20230101 --datebefore 20231231 "CHANNEL_URL"
```

### View Count Filters
```bash
# Videos with 1M+ views
yt-dlp --match-filter "view_count > 1000000" "CHANNEL_URL"

# Videos with less than 10K views

```

### Duration Filters
```bash
# Videos longer than 10 minutes
yt-dlp --match-filter "duration > 600" "PLAYLIST_URL"

# Videos shorter than 5 minutes

```

```

## Integration with Other Tools

### FFmpeg Integration
yt-dlp automatically uses ffmpeg when installed for:
- Merging video and audio streams
- Converting formats
- Embedding thumbnails and metadata
- Post-processing

  --external-downloader-args "-x 16 -s 16 -k 1M" \
  "URL"
```

## Legal and Ethical Considerations

⚠️ **Important**:
- Only download content you have rights to
- Respect copyright and Terms of Service
- Don't distribute copyrighted content
- YouTube's ToS prohibits downloading most content
- Use for personal archival and educational purposes
- Many creators offer official download options
- Consider supporting creators through official channels

## Performance Tips

1. **Use Archive Files**: Track downloads to avoid re-downloading
2. **Limit Rate**: Prevent network congestion with `--limit-rate`
3. **Concurrent Fragments**: Speed up with `--concurrent-fragments 4`
4. **Choose Format Wisely**: Lower quality = faster download
5. **Use External Downloader**: aria2c can be faster than built-in
6. **Batch Smartly**: Process in chunks, not all at once

## Updates

Keep yt-dlp updated for best compatibility:
```bash
# Update via pip
pip install -U yt-dlp

# Check version
yt-dlp --version
```
