Limits

Starting point: WebM - VP9 video with Opus audio and alpha support. Apple editors accept it unevenly; keep MP4 for editing round-trips. Closed-caption tracks need separate extraction before conversion. Encode LXF (MPEG-2 / PCM) from WebM at a bitrate near the source, and confirm the audio track before converting.
