About MPEG, MPG & MP4

We always see or hear two video formats – MPEG and MPG. In essence, there is no difference between them. The reason why the names are different is that in older Windows, only three-letter file names are accepted. Therefore, the .mpeg video file has to be shortened to .mpg for saving. But there are still some video sites that do not accept uploading videos in MPG format because it belongs to an older standard.
So far, MPEG has optimized several compression format standards including MPEG-4, and MPEG-4 also contains several different standards and aspects, MP4 is only one of them, which stands for MPEG-4 Part 14.

Why convert MPG to MP4?

MP4 is a more inclusive file format, which can be used not only to store video, audio, but also as an extension of subtitles, images and other files, and supports you to combine different multimedia data into one file.
