⚠ HEVC/H.265 CODEC DETECTED
This codec is very memory-intensive in WebAssembly. High risk of failure.
RECOMMENDED:
Use "Copy to MP4 (Fast)" - minimal memory, no re-encoding
Avoid conversion or compression operations
For best results, use desktop FFmpeg instead

▶ How It Works
All processing happens in your browser using WebAssembly
Your videos never leave your computer - completely private
First use loads FFmpeg (~22MB) - subsequent uses are faster
Processing is slower than desktop apps (expect 20-50x slower)
Works best with files under 500MB for reasonable processing times
▶ Tips for Best Results
Try "Copy to MP4 (Fast)" first - fastest option, no re-encoding
For large files or complex codecs (HEVC/H265), use simpler presets first
If you get memory errors, try with a smaller file or lower resolution
Screen recordings work best with "Copy to MP4" or "Compress for Web"
