Initially, it was developed for satellite and terrestrial broadcasts. Today, it’s common in most HD camcorders, and the video is stored in DV and MiniDV tapes.

MKV is a container format for holding multiple audio, video, picture, and text data such as subtitle tracks. It is similar to other common containers like MP4 and AVI, although MKV is open in the specification. For video contents, MKV uses a .mkv filename extension, .mka for audios, and .mks for subtitles.
