Limits
Starting point: WebM - VP9 video with Opus audio and alpha support. Apple editors accept it unevenly; keep MP4 for editing round-trips. Odd frame dimensions get padded, so check borders after conversion. Encode AMV (MPEG-4 / MP3) from WebM at a bitrate near the source, and confirm the audio track before converting.
