MKV (which stands for Matroshka) 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. For example, users of Apple smartphones cannot open MKV files on their devices, and even Mac users can encounter difficulties opening and playing these videos. In this 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.
