MKV File Extension Details and Tips


Many people who download a file with the extension MKV will often try to play it back with video player software they have installed on their systems. Most of the time this doesn't work. While a great selection of players support the playback of Matroska files, often the proper decoders for the streams contained in the files are missing. It is important to understand exactly what Matroska files are. Here we introduce the MKV File Extension Details and Tips.

What is MKV

A .mkv file is a Matroska video/audio multimedia file. Matroska is not a video codec as it is often thought to be, but a container like MOV and AVI, or an envelope that can hold many different codecs at the same time. As the name implies (the Russian egg-shaped dolls contained within one another) Matroska can contain video (DivX, Xvid, RV9, etc), sound (MP3, MP2, Ogg, AC3, AAC, DTS, PCM), as well as subtitles (SRT, ASS, SSA, USF, etc) in the same file.

The aim of developing Matroska was to provide a flexible and cross-platform alternative to AVI, ASF, MP4, MPG, MOV, and RM. Its main features include fast seeking, high error recovery, modularly extendable, selectable subtitle and audio streams, chapter entries, menus, and streamable over the internet. An example of a Matroska file is a complete video file that includes a video stream and an audio stream, as well as subtitles and a menu system.

How to Play a MKV file

As we described Matroska is a container format file that stores multiple streams (video, audio and subtitles). These streams may require you to install decoding software and filters to playback depending on what player you use.

The Easiest Method: VLC

For most MKV files you find, there is a player not based on DirectShow (so you probably won't have to install any extra decoding software or filters) that has support for Matroska files- VLC. With the VLC player you are actually getting two things; a fine player with support for Matroska, and support for most video and audio streams you will find in an MKV file. This means that you most likely will not have to install any extra codecs or filters, depending on what your streams are.

Important Note: While VLC will work for most MKV files you will find, the package does not include any proprietary codecs. RealVideo and ON2 VP6 are examples of codecs not packed with VLC for this reason. Therefore with VLC, if you get a Matroska file that contains RealVideo, you are pretty much in the dark and will have to look for another playback option.(See how to play MKV in VLC.)

Another choice- Windows Media Player

Plus, several media players based on DirectShow like Windows Media Player will play back MKV files perfectly, but the key precondition is that you have the proper codecs and filters installed. (See how to play MKV in Windows Media Player.)

Why Convert MKV files

As you see, although there are some media players can support MKV videos, a lot of limits and potential troubles exist still. The basic reason is the complex codecs contained in a MKV file.
