What is an MKV File and how is it played?

January 27th, 2011

Video container format similar to the .AVI, .ASF, and .MOV formats; supports several types of audio and video codecs; may also include .SRT, .SSA, or USF (Universal Subtitle Format) subtitles and supports VobSub subtitles from DVDs.

The Matroska video format has become popular in the anime fan-subbing community (where users create subtitles) since it supports multiple audio and subtitle tracks in the same file.
An MKV file is a Matroska file. Matroska is an open source container format. It is an alternative to the popular AVI and MP4 formats and it also surpasses them in many areas.

DivX Player supports MKV files on both Mac and Windows systems. MKV files can also be played on Palm, Symbian, and Pocket PC mobile devices using the CorePlayer Mobile software.
