MKV vs MP4

MKV is a Matroska multimedia container format that is capable of encapsulating video, multiple audio tracks, and subtitles into a single file. Because MKV is open-source and supports different types of video, audio, and subtitles encoding, including descriptions, ratings, cover art, and even chapter points, it serves as the best encapsulation format of high-definition movies and TV shows, especially the Blu-ray video.

Unlike MKV, MP4 is an international standard for audiovisual coding, and it is one of the most popular and common video containers that stores a bunch of data like video, audio, and subtitles that have been compressed. It is an abbreviation of the MPEG-4 part 14 video file. With the high degree of compression used in MP4 videos, it allows the files to be higher quality preserved but much smaller in size than MKV and other video formats.
