Performance Tips
Image Plugin
Info
- Use WebP format for 25-30% file size reduction vs JPEG - Batch process
images with the
batchcommand for better throughput - Set appropriate quality levels (75-85 recommended for most use cases) - Resize first before applying filters to improve performance
Video Plugin
Info
- Use H.265 codec for 40-50% file size reduction vs H.264 - GPU
acceleration available with
-gpuflag (2-4x faster) - Reduce resolution before complex effects - Batch multiple videos for better disk I/O optimization
Audio Plugin
Info
- MP3 @ 320k balances quality and file size - Normalization before merging prevents level issues - Batch convert multiple files for efficiency - Consider FLAC for lossless archival
Scaling Performance
Parallel Processing
All plugins support parallel processing for batch operations:
# Process 100 images in parallel
mediaproc image batch --input /path/*.jpg --workers 8
Memory Management
For large batch operations, adjust worker count based on available memory:
- 2GB available:
--workers 2 - 8GB available:
--workers 4 - 16GB available:
--workers 8 - 32GB+ available:
--workers 16
Disk I/O Optimization
- Use SSD for input/output directories
- Separate source and destination directories on different disks
- Monitor disk usage with
mediaproc info --monitor
Limitations & Constraints
Warning
- Maximum file size: 500GB (theoretical limit) - Maximum image dimensions: 256K x 256K pixels - Maximum audio channels: 32 - Concurrent processes: Limited by available CPU cores - Memory per operation: Limited to available RAM
