Limits
Starting point: WebM - VP9 video with Opus audio and alpha support. Apple editors accept it unevenly; keep MP4 for editing round-trips. Ripped discs may split titles across files; convert each title separately. Encode VOB (MPEG-2 / AC-3) from WebM at a bitrate near the source, and confirm the audio track before converting.
How conversion works
Conversion runs entirely in your browser with FFmpeg WASM. Files never leave your device.
