The Comprehensive Understanding of MP4 VS MPG: Choose the One You Need

1. MP4 and MPG: The Definition of the Two Formats

As mentioned just now, MP4 and MPG are two video container formats functioning as a package that stores multiple media files. Here are the basic definition and origins of them:

MP4, also known as MPEG-4 Part 14, was originally created in 2001 based on the QuickTime File Format MOV. But it was re-released in 2003 as the MPEG-4 Part 14 version that we see today. MP4 is the most common video file format featuring multiple-functionality and high compression. It can not only save videos, but also audio, subtitles and images.

MPG and MPEG actually are the same thing. The MPEG was abbreviated to MPG because some older Windows versions required a three-letter file extension. So the comparison of MP4 and MPG is also MP4 VS MPEG. MPG is developed by the Moving Picture Experts Group, the same team who later brought MP4 to the public. MPG is commonly used for storing videos, audio, as well as metadata information.
