File format information for MKV and AVI

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.

Extension	AVI
Full Name	Audio Video Interleave
Type	Video
Mime Type	video/x-msvideo
Format	Binary

The AVI video file format is a general-purpose multimedia format for housing video and audio data. Created by Microsoft in the early 1990s, the format has, over the years, garnered widespread support; however, with more modern and capable formats such as MP4, AVI is now considered a legacy format, with support for it on the decline.

The format allows the storage of both audio and video tracks using a variety of different codes. This allowance for different codes means that some AVI files would not play on devices that did not have the correct codec software installed.

Despite AVI files being superseded by more efficient formats that offer improved codecs and other features, many video editing and playback software can open and play AVI files.
