MKV is the format of files that are compatible with Matroska Multimedia Container. Matroska Multimedia Container is in a free container open standard format – a known file format that has the capacity to hold an unlimited number of videos, audios, subtitle tracks, and pictures in just one file.

It’s designed to be used as a universal format for storing multimedia content such as TV shows or movies. MKV can also hold all MP4 digital elements and compress videos in high quality to smaller files.

On the other hand, MP4 or MPEG-4 is the succession of the MPEG-1 and 2 formats. It’s also in a container format just like MKV that can hold videos, audios, playlists, images, subtitles, and chapter markers defined by MPEG.

This is a container format that allows the combination of various multimedia streams into a single file. MP4 is created and designed to store timed media info in an extensive and flexible format so that multimedia can be managed, interchanged, and edited.

If you want to store and hold movie files compressed and love to watch and have movies on a high-quality file format like Blu-ray and HD videos, it’s very suitable for you to convert your MP4 videos to MKV, especially if you’re using a Mac device.

But if you typically need movie formats that are compatible with portable players like iPhones, iPods, or iPad, it’s fine to stick with MP4. Converting MP4 to MKV on Mac will make better quality. However, it has poor compatibility as compared to MP4 and occupies larger space. These video formats have special purposes, depending on your needs. Their suitability depends on the specific requirements you have.
