## Troubleshooting

### Common Issues

#### Missing Dependencies
If you see warnings about missing dependencies:
1. Check that all requirements are installed: `pip install -r requirements.txt`
2. Install optional tools (ExifTool, FFprobe) for full functionality
3. Verify tools are in your system PATH or set environment variables

#### Slow Performance
- Large collections may take time to load
- Increase page size for fewer requests
- Ensure external tools (ExifTool, FFprobe) are properly installed
- Adjust database connection settings if needed

#### Index Not Updating
- Use `Ctrl/Cmd+S` to manually trigger a scan
- Enable file watcher for automatic updates
- Check permissions on output directory

#### Metadata Extraction Issues
- Verify ExifTool and FFprobe are installed and accessible
- Check file permissions for metadata access
- Some file formats may not contain embedded metadata

### File Locations
- **Index Database**: `<output>/_mjr_index/assets.sqlite`
- **Custom Roots**: `<output>/_mjr_index/custom_roots.json`
- **Collections**: `<output>/_mjr_index/collections/*.json`
- **Temporary ZIPs**: `<output>/_mjr_batch_zips/` (auto-cleaned)

### Security Considerations
- CSRF protection on state-changing endpoints
- Rate limiting on expensive operations
- Path validation to prevent directory traversal
- Trusted proxy configuration for forwarded headers

## Best Practices

### Organization
- Use collections to group related assets
- Apply consistent tagging schemes
- Regularly rate your assets to identify quality results
- Clean up unused collections periodically

### Performance
- Keep collections reasonably sized (under 50,000 items)
- Use filters to narrow down large result sets
- Periodically optimize the database through the maintenance tools
- Monitor index size and rebuild if needed

### Workflow Integration
- Use drag-and-drop to quickly incorporate assets into workflows
- Leverage metadata to reproduce good results
- Share collections with team members
- Use the viewer to compare different generation approaches
