Keep a master copy: repeated exports stack small losses, so archive MP4 before batch MPEG shares.

Limits

Starting point: MP4 - H.264 video with AAC audio in one file. H.264 has no alpha channel, so transparency is dropped. Interlaced sources may need deinterlacing for clean playback. Encode MPEG (MPEG-2 / MP2) from MP4 at a bitrate near the source, and confirm the audio track before converting.
