MKV file format information

Extension	MKV
Full Name	Matroska Multimedia Container
Type	Video
Mime Type	video/x-matroska
Format	Binary

An MKV file, or Matroska Video File, is an audio/video file format created to store multimedia data in a highly compressed format. The MKV format supports a wide variety of audio and video codecs and is a popular format for distributing video files.

The format itself is a container format, meaning it supports many different audio and video tracks, all using different codecs. Along with audio and video, other data, such as chapters, markers, sub-titles, and other useful data, can be stored within the file.

Support for editing MKV files is widespread, with most video editing applications able to open MKV files. Video playback software, however, can sometimes struggle to playback MKV files if they are not equipped with the correct codecs.
