The .mkv extension stands for Matroska Video, a free, open-source multimedia container format. Think of the MKV container as a box that holds all the different parts of the movie in one file. This includes the x264 video stream, the DTS audio track, and potentially additional elements like subtitles, chapter markers, and metadata.
