MKVMatroska Video file format

MKV (Matroska Video) is a multimedia container similar to MOV and AVI format but it supports more than one audio and subtitle track in the same file. An MKV file is the Matroska multimedia container format used for video. MKV is based on Extensible Binary Meta Language and it supports several video and audio compression formats. The major difference between MKV and other video formats is that MKV is a container and not a codec. MKV files are saved with the .mkv file extension. MKV can incorporate audio, video, and subtitles in a single file even if those elements use different types of encoding. For example, you could have an MKV file that contains H.264 video and MP3 or AAC for audio. MKV also supports descriptions, ratings, cover art, and even chapter points.
