Wikipedia gives an explanation of it as: “The Matroska Multimedia Container is an open standard free container format, a file format that can hold an unlimited number of video, audio, picture or subtitle tracks inside a single file. It is intended to serve as a universal format for storing common multimedia content, like movies or TV shows. Matroska is similar in conception to other containers like AVI, MP4 or ASF, but is entirely open in specification, with implementations consisting mostly of open source software. Matroska file types are .MKV for video (with subtitles and audio), .MKA for audio-only files and .MKS for subtitles only. The most common use of .MKV files is to store HD video files.”
Although MKV files have been one of the most popular video formats, most portable devices, video players, video editors, etc. do not give native supports to them. Therefore, it’s necessary for us to convert this format to many other media formats, so as to play or edit them without trouble.
