Matroska Video File

Extension	.mkv
Category	🔵 video
Programs	🔵 VLC Media Player
Main program	🔵 VLC Media Player
Description	🔵 MKV Matroska is an open-source multimedia container format that supports multiple audio and subtitle tracks in a single file. It is the most versatile file type, allowing users to include a variety of data such as videos, audio, text, and images. It is a RAW format that can be easily manipulated and organized based on the specific data tracks needed.
Technical details	🔵 Whether it's video, audio, subtitles, or images, every file will be stored on a separate data line. It is quite similar to the MP4 or AVI format, although when users are packaging an MKV file, they rarely bundle all the tracks within the file. Many media players do not even support the MKV video format, so users need to use specialized media players that can handle the MKV format, such as VLC media player.
