An MPG file is also known as an MPEG video file, and was created by the Moving Pictures Expert Group. It uses fairly basic compression, typically MPEG-1 or MPEG-2, meaning that while it has a smaller file size than uncompressed video files, it’s not as efficient or as small in size as some other formats, such as the more popular MP4 format. MPG files can be opened by many media players, including Microsoft’s Windows Media Player and Apple’s QuickTime Player.

An MP4 file is a video file that has been compressed in a clever way – with the audio undergoing compression separately from the video. This makes it an efficient file and one that is very popular. MP4 files can be opened by almost any media program, are widely used, and really reached the height of popularity when Apple decided it was its go-to video format.

Is MP4 the same as MPEG?

No, is the answer. MP4 is, to all intents and purposes, the same as MPEG-4, but it is not the same as MPEG. MPEG stands for the Moving Pictures Expert Group and MPEG has many different standards ranging from 1 to 21. MPEG-4 is one such standard, and that is often shortened to MP4. MPEG, meanwhile, is often shortened to MPG.

Is MP4 better than MPG?

MP4 files are much smaller in size than MPG files, and, at the same bit-rate, MP4 is also better in quality, as it supports more advanced video codecs. MP4 files are also easier to open across a wider range of applications. MPG still has its place, but increasingly MP4 files are more widely used.

Can Windows 10 convert MPG to MP4?

It can, but a program such as WinX Video Converter (https://www.winxdvd.com/video-converter/) will need to be downloaded first. Alternatively, you can use an online file converter, such as Zamzar, which converts MPG to MP4 in real time, and with no need to download any software.

Is MPEG-4 a codec?

MPEG-4 is a codec that was developed by the Moving Pictures Expert Group (MPEG). MPEG was the first codec it developed, and since then standards have ranged from 1-21, with MPEG-4 being one such standard.
