What is an MKV file?
An MKV file is a video file saved in the Matroska multimedia container format that often stores short video clips, TV shows, and movies. It supports several types of audio and video codecs and may include .SRT, .SSA, .USF (Universal Subtitle Format), or VobSub subtitles. Many video players can open MKV files, including Microsoft Windows Media Player 2022 and VideoLAN VLC media player.
More Information
The Matroska multimedia container format is open source and was initially released in December 2002. It is similar to the .AVI, .ASF, and .MOV formats and can contain any number of video, audio, image, and subtitle tracks. Multimedia files that utilize the Matroska container format and store one or more video tracks are known as Matroska Video files and are distinguished by the .mkv file extension.
In addition to storing short video clips, TV shows, and movies, it has become popular in the anime fan-subbing community for saving multimedia with subtitles. The MKV format is especially helpful since it supports multiple audio and subtitle tracks in the same file.
NOTE: The Matroska name comes from the Russian Matryoshka doll, which contains numerous more miniature, nested dolls of the same shape.
