MPG is a digital video format standardized by the Moving Picture Experts Group (MPEG). Files with the .MPG extension typically incorporate MPEG-1 or MPEG-2 audio and video compression. MPG files can store video, audio, and metadata interleaved together. However, the MOV video format, as a format standardized more than a decade ago, has already gone outdated as the video technology keeps evolving in a fast pace. Nowadays, more and more video player applications or devices no longer have the MPG file format support, and only support more modern and efficient video format like MP4. In that case, if you have one or more MPG video filers, chances are you can’t successfully play it or edit it with the application you have in your computer, especially when it is a Mac computer. To solve that problem, one of the most effective way is to convert the MPG video format to formats like MP4. To do that, you need a decent MPG to MP4 converter program installed on your Mac. So today let’s have a look at some of the best MPG to MP4 converter tools and also see how to easily convert MPG to MP4 with these tools.
