About MKV and MP3

MKV

MKV (Matroska) is a flexible video container that can hold several audio and subtitle tracks. It’s common for films, but many devices won’t play it.

MP3

MP3 is the most widely supported audio format. Its lossy compression keeps files small, and it plays on practically every device.
