MPG Video Format

MPG Converter

The Motion Pictures Experts Group (MPEG) developed the MPG video file format in the early 1990s. Videos with the .mpg file extension can be either MPEG-1 or MPEG-2 files. Both these types of video use lossy compression to make the files smaller for storing and sharing, and are formats that contain audio, video and metadata. The lossy compression can affect video and audio quality, but MPG is still a very popular and widely supported format. MPEG-2 was typically used for DVDs or TV.

Both MPEG-1 and MPEG-2 have ISO certification and almost all video applications and devices can open an MPG file, including Windows Media Player, Apple QuickTime and VLC. In recent years, MP4 and HEVC formats have become more popular with people filming on smartphones, sharing videos, or uploading video files to social media.

MP4 Video Format

MP4 Converter

MP4, sometimes called MPEG4, is one of the most common video formats. MP4 was developed to be easily played and shared. It was originally developed by the Moving Picture Experts Group (MPEG) but has become an ISO standard, meaning that it’s now maintained by the International Organisation for Standardization. As MP4 is a standardised format, it will normally play easily on most devices and media players, including Windows Media Player, QuickTime, and VLC. MP4 is usually the preferred format for uploading videos to YouTube, Vimeo or other websites.

MP4 videos are made up of video and audio elements that are compressed separately. The video part is usually compressed with MPEG-4, and the audio is usually compressed using AAC, which is the audio format associated with iTunes. Because both file elements are compressed, MP4s normally have a smaller file size than many other video formats, but still maintain relatively high quality for sharing online.

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.

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.

It can, but a program such as WinX 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.

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.
