The MKV extension is used by the Matroska project, as a catch-all multimedia container. Like MOV and AVI files, they can be used to store video media. But unlike those formats, they can also hold MP3 or FLAC files as well, making them a complete audio and visual file compiler. MKV files can hold audio formats at the same time as video formats, art files, chapter points, even subtitle files as well, making them perfect for creating complete movie or video experiences. The .mkv format can also incorporate files that use different encoding as well - for example, there’s undoubtedly thousands of people playing mkv files that contain H.264 video and AAC audio! It turns several media formats into one cohesive MKV file format.

Categories of Matroska Files

The Matroska MKV multimedia container is a free, open-source format that contains four types of files within the container: MKV (Matroska Video), MKA (Matroska Audio), MKS (subtitles), and MK3D (stereoscopic/3D video). If you’re looking for how to play an MKV file on Mac, these are your best choices, and what follows is a quick breakdown of them.

MKV Files

This format is commonly used for HD movies and TV shows. It’s great for video, movie audio, and videos with subtitles. The best players that support the MKV extension include Elmedia Player, Windows Media Player, 5KPlayer (with the MKV codec), and VLC, though sound and subtitle support might not be available.

MKA Files

This format usually contains various audio compression formats including MP2, MP3, AAC, AC3, DTS, and many more. It’s used normally as an audio file, able to support whole music albums as well as being able to support karaoke subtitles. You can also easily divide audio files into separate tracks or chapters, and merge it with the .MKV format for a complete audio/visual experience.

MKS Files

With the MKS extension, you can easily import various subtitle formats including VobSub (.sub), SubRip (.srt), Sub Station Alpha (.ssa/.ass), and Core Media Player XML universal subtitle format (.usf). All open-source MKV players can launch an MKS file just by double-clicking it.

MK3D Files

The MK3D extension is typically found in home theatres because it enables 3D visuals in .MKV format media files. Using two isolated video tracks, it provides 3D video support. Most of the time this is done with two isolated video tracks, one for each eye. However, it’s also been known to be one track with data for both eyes in differing formats.
