Now we get lots of videos online in MKV format as it is used to store HD videos files and with smaller file size. MKV (“Matroska Video”). 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.
