When not to convert MKV to AVI
- Skip AVI for archival masters: lossy compression discards detail, so keep the MKV original.
- Flatten transparency first: AVI has no alpha channel, so composite MKV over a background color.

Starting point: MKV - Multi-track container for video, audio, subtitles. Only the selected tracks carry over, so pick audio and subtitles first. Old codecs inside may need transcoding before modern players open them. Encode AVI (MPEG-4 / MP3) from MKV at a bitrate near the source, and confirm the audio track before converting.
