What is an MKV file?
MKV – Matroska video. MKV (Matroska) is a flexible open container that can hold any number of video, sound and subtitle tracks. Media players love it; phones and some TVs do not. Converting makes a new file: the video is decoded and encoded again, so converting from a format that lost detail never brings it back.
