Limits
Starting point: MP4 - H.264 video with AAC audio in one file. H.264 has no alpha channel, so transparency is dropped. Odd frame dimensions get padded, so check borders after conversion. Encode AMV (MPEG-4 / MP3) from MP4 at a bitrate near the source, and confirm the audio track before converting.
