MKV, short for Matroska Video, is a video format originated in Russia in 2002. MKV is actually not an audio or video compression format. MKV is a multimedia container format that can have audio, video, and subtitles into a single file, even if those elements use different types of encoding methods. So, one of the advantages of an MKV file is that it can incorporate multiple subtitles, high definition MP3 audio tracks and menu files in one single file, all while keeping the high quality of the video and the good compatibility of the file. Usually, if you have an MP4 video file, you can convert the MP4 to MKV with the help of an MP4 to MKV converter program. But how do you convert MP4 to MKV?
