Limits

Starting point: WebM - VP9 video with Opus audio and alpha support. Apple editors accept it unevenly; keep MP4 for editing round-trips. Hardware support is thin, so convert for phones and editors. Encode OGV (Theora / Vorbis) from WebM at a bitrate near the source, and confirm the audio track before converting.
