How to convert MKV to MP4 on Mac

Edited by Pat Bitton

September 12, 2019

MKV (which stands for Matroska) is a universal format used for storing multimedia content, like movies, concert videos or TV shows, in HD. Although this format is getting more and more popular, it’s only supported by a limited number of devices.

Let’s have a look at solutions to other common problems related to MKV files.

Can’t open a video file?

Either your device doesn’t support the file’s format, or you need to install a special media player. In both cases, converting the file to a suitable format is the best solution.

Your video is distorted?

The video file must be too large. Reducing its size in a conversion app might help.

Sound problems?

Usually, the source of the problem is the incorrect audio codec. Change it with video converter.

How to Do Lossless Conversion from MKV to MP4 on Mac

Unfortunately, users of Apple smartphones cannot open MKV files on their devices, and even Mac users can encounter difficulties opening and playing these videos. In these instances, you have to convert MKV to MP4 on Mac. The best way to do this is to use a dedicated program. Movavi Video Converter can help you transform your files extra quickly, thanks to its SuperSpeed mode.

What is SuperSpeed mode?

The fastest way to convert MKV to MP4 on Mac is to transfer data from one container to another without compression. SuperSpeed mode is a function in Movavi Video Converter that enables format changes in the blink of an eye without re-encoding or associated quality loss.

There are a few limitations though, that you need to take into account when using SuperSpeed conversion:

  • Codecs, resolution, bitrate, and other video parameters need to remain unchanged.
  • Special effects cannot be applied: e.g. you cannot rotate your video or add watermarks.
  • With our software, you can easily change format from MKV to MP4 on Mac. Movavi’s MKV lossless converter for Mac supports not only MKV and MP4, but many other video, audio and image formats as well.

    MP4 vs. MKV Comparison

    Let’s have a closer look at differences between MP4 and MKV formats.

    MP4 (MPEG-4 Part 14) is a container format used for storing video and audio streams. Low quality loss combined with high compression levels, as well as its compatibility with almost all default media players, make MP4 format one of the most widespread formats on the internet. You can play MP4 files with any default media player.

    MKV (Matroska Multimedia Container) is a free, open-standard video container format. MKV files are able to contain an unlimited number of video, audio, and subtitle tracks in one file. That’s why this format is widely used for storing multimedia content such as movies and TV shows. Using this format, you can watch your favorite movies with any combination of audio tracks and subtitles. It’s less universal than MP4 because you need to install a special media player to open MKV files, and you can’t open such files on iPhones.
