MKV vs MP4: What Are the Differences and How to Convert
MP4 and MKV are two of the most frequently-used video file formats, also called container formats. Containers are a collection of files containing all the components of a video including streams, metadata information such as the title, copyright holder, and creation date, and more. As a container format, they are both popular and have good quality. So, MKV vs MP4, which is better? What are the differences between MKV and MP4? To get the answers to the above questions, you can read this post about the comparison of MKV vs MP4.
What Is MKV?
MKV, also known as Matroska (Matroska Multimedia Container), was developed in 2002 by Steve Lhomme. It is a free and open-standard container format that doesn’t need any license requirement. Matroska is able to contain video, multiple tracks, image, subtitles, etc., so you can find Matroska in Matroska video files, Matroska audio files, Matroska subtitles files and Matroska stereoscopic/3D video files. In addition, WebM files are a major subset of Matroska.
Matroska can be used for DRM due to its general encryption capability. The MKV container uses a block-oriented structure so that software can encrypt the structure of a DRM-protected file and execute operations on it. If you’re going to use a video container format for long-term retention, the MKV format would be a better choice.
What Is MP4?
A file with the MP4 file extension is an abbreviation for an MPEG-4 Video file, which is created by the Moving Pictures Experts Group (MPEG) in late 1998, as a standardized video coding format. Owing to its wide and varying use, it becomes one of the most popular container formats that can hold video, audio and subtitles images, chapters in a single file. Similar to MKV, it can also store advanced content such as 3D graphics, menus and user interactivity.
Many codecs are officially registered for MP4 like H.264 (which is the same as MPEG-4, Part 10) and H.265. Other codecs can be downloaded and added to the software. Also, MP4 files can incorporate DRM. That means software can discern the content on it effectively.
Now, you can go to the next part to get the differences between MKV and MP4.
