Some people are confused about the MP4 and MPEG4, and they asking that: Does MPEG4 means MP4?, Is MPEG-4 the same as MP4?, etc. Actually, they are absolutely not the same. After reading this simple introduction, you will have a clear understanding of these two concepts.

Understand MP4 and MPEG4 with Simple Description

#1. Definition of MP4 and MPEG4

To figure out the difference between MP4 and MPEG4, we have to understand 2 basic term first: video codec and media container. It can be shown with the following formula:

Media Container = video format (video codec) + audio format (audio codec) + subtitle


Then, we will go through the definition of MP4 and MPEG-4

What is MPEG-4:

MPEG-4 is a method of defining compression of audio and visual digital data (AV). With the development of MPEG4, it is divided into a number of parts (each part covers a certain aspect of the whole specification) including MPEG-4 part 2, MPEG-4 part 10, MPEG-4 part 14 and others.

Actually, MPEG-4 is a complex thing that include knowledge in various aspects. To know more further, go to Wikipedia.

What is MP4:

MP4, is an abbreviated term for MPEG-4 Part 14 (not for MPEG4). It can be a video file extension (.mp4), a container format used to store both video and audio data, as well as a video format.


#2. Relation Between MP4 and MPEG4

We have mention that MP4 is the abbreviated term for MPEG-4 Part 14. MPEG-4 Part 14 is one of the part of MPEG-4 compressing algorithm. And, it is a digital multimedia format (container format) that used to store video, audio, subtitles, images and suchlike data.

The only official file extension of MPEG-4 Part 14 is .mp4. But it also has other file extensions such as .m4v, .m4p, .m4b and m4a. You can refer to this page to know more about these MPEG-4 Part 14 filename extensions.


#3. MP4 VS MPEG4: The Differences between MPEG4 and MP4

From above content, we can know:

MP4: It can be a file extension, a video format or a video container.

MPEG-4: It's a compression method of the MPEG group, especially designed for low-bandwidth (less than 1.5MBit/sec bitrate) video/audio encoding purposes. And, MP4 is one of the media container format for MPEG-4. Except for it, videos encoded in MPEG-4 also has other media container formats like Matroska (MKV), AVI, MXF, Ogg and QuickTime.


Now, let's see some examples to make the relationship more intuitive.

MP4 (.mp4) = MP4 video format (.mpeg4/.h264 video codec) + audio format (mp3, aac, etc.) + subtitle

AVI (.avi) = MP4 video format (.mpeg4/.h264 video codec) + audio format (mp3, aac, etc.) + subtitle

MKV (.mkv) = MP4 video format (.mpeg4/.h264 video codec) + audio format (mp3, aac, etc.) + subtitle
