MP4 to AVI Converter
Understanding AVI encoding and alternative solutions
About Browser-Based AVI Encoding
AVI (High Efficiency video Container) is Apple's proprietary video format. While we can easily decode AVI to other formats, encoding videos to AVI in a web browser presents significant technical challenges:
- Browsers don't natively support AVI encoding
- Requires large WebAssembly libraries (~2-5MB)
- Complex low-level API integration needed
- Potential performance issues and slow conversion
To maintain a fast, lightweight experience, we've chosen not to implement browser-based AVI encoding at this time.
