What is the MKV format and how to change it?

MKV - what's the format? This is a video container, similar to MOV and AVI, which supports an unlimited number of audio, image and subtitle tracks (for example, SRT or USF).

Description

MKV - what's the format? The Matroska Multimedia Container is an open standard, free file format that can contain an unlimited number of video, audio, images, or subtitle tracks in one container. Designed to be used as a universal format for storing common multimedia content, such as movies or TV shows. In comparison with the AVI format, MKV is conceptually similar to the technological solution of formats such as MP4 or Advanced Systems Format (ASF). The content of the file is fully disclosed in the specification: the implementation consists of open source software. Matroska file extensions:

  • .MKV - for video (with subtitles and audio);

  • .MK3D - for stereoscopic video;

  • .MKA - for audio files;

  • .MKS - for subtitles.

History

MKV files, also known as Matroska video materials (from the name of the Russian souvenir toy “Matryoshka”), appeared in Russia in 2002. Lead developer Lasse Kärkkäinen worked with project founder Steve Lomme and a team of programmers to create a comprehensive multimedia container file format.

Goals

The Matroska team expressed some of their long-term goals on the Doom9.org and Hydrogen Audio forums:

  • the creation of a modern, flexible, expandable, cross-platform multimedia container format;

  • developing robust streaming support;

  • development of a menu system similar to a DVD system based on EBML;

  • the invention of a set of tools for creating and editing MKV files;

  • expanding the gallery of libraries that can be used to provide Matroska support to developers for their applications;

  • working with equipment manufacturers includes Matroska support in embedded multimedia devices;

  • MKV support in various operating systems and hardware platforms.

Development

MKV - what kind of format and what are its features? The project is supported by a non-profit organization in France and is free for use by the standard.Its technical specifications are available for private and commercial use. The Matroska development team licenses its projects under the LGPL, with parse and play libraries available under BSD licenses.

Versioning support

Contrary to popular belief, MKV files are multimedia container formats, not an audio or video compression format. A container can enclose audio, video, and subtitles in a single file, even if these elements use different types of encoding. For example, you might have an MKV file that contains H.264 video and something like MP3 or AAC for audio.

Matroska developers have included several key features that prevent data aging:

  • quick search;

  • support for chapters, menus and metadata;

  • selection of various audio and video streams;

  • compatibility with streaming data;

  • subtitle support;

  • error recovery that allows you to play damaged files.

The MKV container itself also supports almost any audio and video format, which makes it highly adaptive and easy to use.
