What is MKV?

Full name

Matroska Multimedia Container

Format type


Developed by

Lasse Kärkkäinen


MKV (or Matroska Multimedia Container) is a free, open source video container format created in 2002. It’s officially called Matroska after the Russian matryoshka dolls because all the video, audio, and subtitle tracks are held within a single file. This format enables synchronous playback of audio and video tracks. Since MKV supports a large number of codecs and even uncompressed video, this format retains the original quality, allowing you to enjoy your videos in HD. Check this table if you want to know how to open MKV files and which programs can play them.

File extension

.mkv, .mk3d, .mka, .mks

Technical details

Videos with the MKV file type have a data channel for each type of track, making this format closer to other media containers such as AVI or MP4. A disadvantage of the MKV format is that very few modern programs can play files with these specifications correctly, so users have to install additional applications or codecs, for example, the VLC player or K-Lite Codec Pack.

MJPEG, short for Motion JPEG, is a video compression format that stands out for its simplicity and versatility. Unlike other video formats that use complex algorithms to compress video data, MJPEG takes a straightforward approach. It compresses each frame of a video as a separate JPEG image, resulting in excellent image quality with minimal compression artifacts.

Technical details

One of MJPEG's unique characteristics is its suitability for editing and frame-by-frame analysis. Since each frame is individually compressed, you can easily access and edit specific frames without affecting others, making it a valuable tool for video professionals and enthusiasts. While MJPEG may not be the most space-efficient format due to its frame-by-frame compression, its straightforward encoding and decoding process make it a reliable choice for certain applications, including video surveillance and medical imaging. Its simplicity and quality make MJPEG a format worth considering when precision and ease of editing are top priorities.
