Step 1: Add MKV files

Step 2: Select conversion options

Once the MKV to MP4 converter has loaded your MKV file(s), in the lower left-hand corner of screen you'll find the "Profile" drop-down menu. Select that to open the format panel.

Digital video is stored in a container, and the video and audio data are compressed within that file using a codec. So here choose the format H.264 Video (*.mp4) or MPEG-4 Video (*.mp4) under "General Video".

However, to keep the quality of output files, if the MKVs you want to convert to MP4 are high definition, here you will need to go to "HD Video" category and select HD MP4.

There are a variety of custom parameters, for advanced user, under "Settings" buttons that can be optionally modified to further optimize. Generally, it's not really necessary since the pre-configured settings are OK.

This Mac MKV to MP4 converter doesn't just allow you to choose a specific format. It has a good range of preset options to convert videos for a variety playing devices as can be seen on the left side. Simply choose the device that you are most likely to watch the video on and it will optimize a whole range of encoding options for that.

Edit MKV files before the conversion: (optional)

There is a handy built-in video editor can handle editing for a video before your MKV to MP4 file conversion. After you have loaded your source file, simply click on the "Effect", "Trim", "Crop" button on the top menu, or you can right click the mouse to bring up the window. More details on here.

After the settings and the previews of videos, straight, click "Convert" to begin the Mac MKV to MP4 format conversion. How long the encoding takes is very much dependant on the size of the video files you have added, the encoding settings and the power of your Mac.
