Almost everyone knows about MKV, a file format holding video, audio, picture, or subtitle tracks in one file, just like AVI or ASF. But normally, it is not the main default format of digital devices including iPhone, Android-based smartphones and many video players like QuickTime on Mac. Imaging what a pathetic thing if you downloaded your favourite HD movie but failed to have it played on your phone or MP4 player only because of its incompatible MKV format! In that occasion, you possibly cannot wait to convert MKV to other compatible formats so that the movie or other MKV videos could successfully work on. Mp4 format, which is supported by a large number of electronic products including smartphones and DVD players, becomes the appropriate target format especially when you have your own Mp4 player to enjoy movies at leisure time.
