Limits
Starting point: MP4 - H.264 video with AAC audio in one file. H.264 has no alpha channel, so transparency is dropped. High-bitrate files take longer; confirm audio track selection first. Encode M2TS (H.264 / AAC) from MP4 at a bitrate near the source, and confirm the audio track before converting.
