MPG versus MP4 | Which Is Better?

1. Overview of MPG and MP4

MPG is a video file format that uses either MPEG-1 or MPEG-2 compression. It stores video, audio, and metadata interleaved together and is a popular format to distribute videos on the Internet.

MP4 was developed based on the QuickTime File Format MOV but re-created as MPEG-4 Part 14 two years later. It stores video, audio, and other data, such as subtitles and still images, and allows streaming over the Internet like most modern container formats.

2. MPG and MP4 Supported Video Codecs

MPG supported video codecs: MPEG-1, MPEG-2

MP4 supported video codecs: H.265/HEVC, H.264/AVC, H.263, AV1, MPEG-1 Video, MPEG-2 Video, MPEG-4 Visual, M-JPEG, MJ2, Microsoft MPEG4 V2, VP8, VP9, VC-1, Sorenson, Cinepak, Theora, Dirac, MVC

3. MPG vs MP4 Quality

At the same video bitrate, MP4 provides better quality than MPG because it uses more advanced video codecs like H.264 and H.265, which compress videos with less data loss in a smaller file size than MPEG-1 and MPEG-2.

Therefore, MP4 has an edge over MPG in terms of quality.

4. MPG vs MP4 File Size

In most cases, video quality and file size are proportionate. When the file size gets smaller, the video quality is also lower.

However, this is not always the case. A video file size is affected by many factors, such as the bitrate, resolution, and encoding method. Modern video codecs like H.265 and H.265 implement a better compression ratio than MPEG-1 at the same quality.

That is to say, videos encoded in MP4 H.265 are much smaller than those encoded in MPG using the MPEG-1 or MPEG-2 standards.

5. MPG vs MP4 Compatibility

MPG can be recognized by major media players. But some platforms, like OneDrive, iPhone, and iPad, do not support .mpg files.

MP4 is the most commonly used file format for streaming videos. Meanwhile, many media players, devices, and applications support this format and use it as the default option for loading and playing video files.

After learning the detailed difference between MPG and MP4, do you know which one to choose, MPG or MP4? Generally speaking, MP4 is perfect for playing videos, reducing file size, and uploading videos to social media sites like YouTube, Instagram, and Facebook. If you need to burn a DVD, choose MPG, as MPEG-1 and MPEG-2 are good practices on CDs, DVDs, VCDs, SVCDs, and other optical discs.

In a word, there is no conclusion about which is better between MP4 and MPG. Each format has its advantages and disadvantages. You can choose MPG or MP4 based on the situation you need the format for.

Pros of MPG:

• Compatible with most media players • Most widely-used for recording videos
