How to Convert .MPG Files to .MP4 Files

I have a MPG file that I cannot watch on my computer. My computer will play MP4. So any program help me convert MPG to MP4 easily?

If you are looking for the best ways to convert MPG to MP4, this article is for you as it covers exactly that in great depth. You will not only get to know the best MPG to MP4 converter tools but also learn how to actually perform the conversion. Let’s get started!

Part 1. Why Convert .MPG files to .MP4

The video container format MPEG, written MPG back when Windows could only handle 3 letter file extensions, is abbreviated from Motion Picture Experts Group. Video compression formats MPEG-1 and MPEG-2 are generally used, with resolutions up to 720i, which has now been superseded by MPEG-4 Part 2, which is stored in the container format MP4.

MP4 is an international standard and probably the most popular video and audio file container at present, with native support in Windows, Macs, iOS, and Android devices. Although the format is lossy, this enables small file sizes, whilst retaining a good level of video quality.

You might want to convert MPG files to MP4 because MP4 is more widely supported.

NOTE: It’s important to distinguish between file container formats and compression formats, or codecs. For example, MP4 is a container, and can hold different types of video compression, for example, MPEG-2 Part 2, MPEG-4 AVC, or HEVC, as well as audio (again compressed in a variety of formats) and metadata (for example subtitles). Some codecs can be wrapped in multiple different containers. Containers are sometimes referred to as file extensions, e.g. MOV, MP4, or AVI, but it’s important to remember that there can be different types of video within these file formats.
