About the formats
MKV is a flexible open video container that can hold multiple audio tracks and subtitles. It is popular for movies and series, but not every device or editor supports it.
MP4 is the most compatible video format in the world. It plays on virtually every phone, browser, TV and editing app while keeping file sizes reasonable.
