MKV is a format of media files. It can include a number of different file types of audio tracks and subtitle tracks, and its video encoding has a very large degree of freedom, which can be DivX, XviD, or even types of stream video such as Real Video, etc. In fact, it is a whole new type multimedia container format called Matroska. This advanced, open-source package format has shown us a very good prospect. Some people see it as a replacement for AVI.
MP4 format, like MKV, is just a packet format. It is widely used in portable media players. It has many different specifications and different players can only play certain specifications. MP4 format is defined on the base of MPEG4 Part 1 specification standard. But the format itself is quite common, not only used to store MPEG4 video formats. For example, Mp4 files may contain H.263 video stream and AMR audio track rail. So although it has no relationship with MPEG4 video compress algorithm, it is definitely a legitimate MP4 files and can be played by many players. In this sense, Mp4 is an independent packet format. Maybe the original design intent is only for MPEG4, but in fact users think it is very easy to use.
