What is an MKV File

MKV files also known as Matroska Video files are an open-source file format that originated in Russia and hence acquired the name from the Russian word called matryoshka which means Nesting Dolls. Basically, MKV files are multimedia container formats that combine video, audio, and subtitles into a single file. That is, a user can incorporate different video and audio files into a single .mkv file format even if the elements use a different type of encoding. These files are highly adaptive and easy to use.  Additionally, it supports almost any video and audio format. It’s worth bearing in mind that the MKV file is not supported by all media players as it is not an industry standard, but there are many options available to play MKV files.
