What is MPG

MPG is technically the same as the more popular MPEG video formats. Created by Moving Pictures Experts Group, this is the file format that is regarded as industry standard. The format is a container file of audio, video, and data file systems, compressed and tested accordingly to produce high quality results. MPG is developed by ISO/IEC, and along with its associated file extensions, is the most preferred video format over the internet today.

What is MOV

MOV is a video file format that works on fairly the same footing as the MPG. However, MOV is more native to Macintosh computers than the MPG file format. Therefore, it is quite safe to say that MOV is the video file for all Apple systems. It plays naturally in the QuickTime player, which is the multimedia player native to Apple devices.


MPG and MOV almost produce the same quality of images simply because they are created with the same platform. As a matter of fact, MOV is the basis used to create the MPG file format. The only difference is that MPG proves to have better support over the internet, as it is mostly associated with Windows-based system. Both video file systems also possess the capability to adapt lossy formats in order to trim down the file size. These two formats are highly portable video files, thus making them playable on almost all devices and gadgets. So if you are using an Apple device such as an iPhone, iPod, or iPad, go for MOV. For all other devices, MPG proves to be more compatible.
