Comparison between MKV and MP4 Formats

File Extension .mkv .mp4
File Type Video File Video File
Definition MKV (also known as Matroska Video) is a container for videos, images, audio and subtitle tracks without limitations. It is mostly chosen for online videos because it supports files in high definition but also a relatively large size for storage. MP4 Videos, which are also called MPEG-4 Part 14 Videos incorporate audio, videos, subtitles and more as a powerful container. It’s compatible with most devices and players at present. You can access a compressed file with easy digital distribution on various platforms.
Technical Details Videos saved in Matroska enjoy wide currency in online media. Each component contained in MKV files adopts its own encoding but the video quality is still guaranteed in this format. Players for MKV can go through all the content in a single MKV file once you open it. File in MP4 format is a lossy one with degraded quality after compression. The security may be weaker because it’s easier to remove metadata and distribute MP4 files without permission. And not all registered codecs in MP4 are supported now.
