What is MKV?
Full name
Matroska Multimedia Container
Format type
Video
Developed by
Lasse Kärkkäinen
Description
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.

What is MP3?
Full name
MPEG-1 Audio Layer III
Format type
Audio
Developed by
Specialists from Fraunhofer Society
Description
The MP3 format was created in 1991, and its specification was published in 1993 as a part of the MPEG-1 standard. Originally, MP3 was made as a proprietary format, but now it is free to use by anyone. MP3 matured into the most widespread audio format in the world. It is probably not possible to find a program that can’t open and play MP3s. But technologies are always developing, and many broadcasting companies now prefer other file types with better compression and less sound quality reduction.
File extension
.mp3
Technical details
MP3 (MPEG-1 Audio Layer III or MPEG-2 Audio Layer III) is a format for the lossy compression of sound. The quality and size of MP3 files are defined by their bitrate. So, if you’re wondering how to compress your audio files while keeping the quality, consider converting them to MP3 with a bitrate of 192 kbit/s or higher. Then you probably won’t be able to hear any difference in the playback.
