For the storage of video data, there is a free and open standard called MKV (Matroska Multimedia Container). The file’s ability to contain an unlimited number of audio, video, image, and subtitle tracks makes it a practical way to save movies, complete TV programmes, and more. The user can navigate to any of the various data tracks using the raw format. Anyone may use the technical specifications for the royalty-free Matroska project. The LGPL (LGNU Lesser General Public License) governs the Matroska libraries, while the BSD licences govern parsing and playback.
Every track, whether it be audio, video, picture, or subtitle, should be saved into a different dataline in a file saved as MVK. Thus, it is comparable to several other container formats like MP4 or AVI, albeit typically, users rarely bundle all of the tracks in an MKV file when packaging it. The majority of media players don’t automatically accept MKV files, so in order to access its content properly, a user must utilise specialised software that can play such media files, like the VLC player.
