About these formats
AVI is one of the oldest video containers, dating back to early Windows. Many older camcorders and programs produced AVI files that modern devices struggle to play.
MKV (Matroska) is a flexible open-source video container that can hold multiple audio tracks and subtitles in one file, popular for high-quality rips and archives.
