What is MKV?

MKV (Matroska Video File) is a new multimedia encapsulation format that can encapsulate a wide range of video in different encodings, audio in 16 or more different formats and subtitles in different languages in a single Matroska Media file. It is also one of the open source multimedia encapsulation formats, and Matroska can provide very good interactive features, and is more convenient and powerful than MPEG.

The most important feature of Matroska is that it can accommodate many different types of encoded video, audio and subtitle streams, even including streaming media like RealMedia and QuickTime. It can be said to be a major overthrow of traditional media encapsulation formats!

It is now almost a universal media container, and the types of video, audio, and subtitles it can encapsulate include AVI files, RealMedia files, Mov and MP4, MPEG files, etc..

What is MP4?

MPEG format: MPEG (Moving Picture Experts Group) is an International Standards Organization (IS0) approved media encapsulation format that is supported by most machines. The MPEG-4 file container format is specified in Layer 1 (mux), 14 (mpg), 15 (avc), etc. MPEG is rich in control features and can have multiple videos (i.e. angles), audio tracks, subtitles (bitmap subtitles), etc.

A simplified version of MPEG, 3GP, is also widely used in quasi-3G cell phones on mobile phones. Sub-file names: dat (for DVD), vob, mpg/mpeg, 3gp/3g2 (for cell phones), etc. To explain an easy mistake, the MP3 (MPEG-1 Layer 3) format that we usually use to listen to music is not the MPEG-3 standard, but the audio compression standard in MPEG-1.
