What is the advantage of MKV over MP4?

What is the advantage of MKV over MP4?

Matroska Video (MKV) does hold a few advantages over MP4. More audio, video, and subtitle codecs are supported by the open-source MKV format than by MP4, offering users more options. This means that if you try to convert an MKV file to an MP4 file using an online video converter MKV to MP4, you might find that some of the MKV file's original features or elements aren't supported in the MP4 format. 

Additionally, MKV files have the ability to store an infinite number of video, audio, picture, or subtitle tracks in one file, which is useful for some applications.
