What Is An MKV File

MKV file

Matroska video files, or MKV files as we know them, originated in 2002 in Russia. They are open source and are available for free. With time, the format improved, and it became the base for the WebM multimedia format in 2010.

Unlike what everyone believes, .mkv file is not a compression format for audio or video. They are multimedia container formats actually that can incorporate video, audio, and subtitles in one single file. It can incorporate them in a single file even when they contain different types of encoding.

These containers were made to be future proof preventing the files they contain from becoming outdated. They did it with the help of certain features like support for Chapter, menu, and metadata along with compatibility for online streaming, subtitle support, error recovery, etc.

This file format is based on EBML, or Extensible Binary Meta Language, a binary standard. However, the structure of EBML resembles XML and it can be interpreted as a binary markup. That’s why it is easy to construct even a very complicated nested structure inside the binary file. And that is how the .MKV file gets all those features that make it future-proof.
