Mpg format is a video file format, the full name is MPEG, that is, moving picture expert group. It is an international standard of moving image compression algorithm, which is supported by almost all computer platforms. The file extension of MPEG format video is usually MPEG or MPG. It includes MPEG- 1, MPEG-2 and MPEG-4. MPEG- 1 is widely used to make VCDs, and most VCDs are compressed in MPEG- 1 format.

What format is mpg?

The five criteria of MPG are:

1、MPEG- 1？

The MPEG- 1 standard was officially released in 1992. The number of this standard is ISO/IEC1172, and its title is "Coding of moving images and their accompanying sounds in digital storage media with bit rate of about 1.5Mb/s".

2、MPEG-2？

MPEG-2 coding standards hope to include coding standards in various fields such as digital TV and image communication. MPEG-2 is divided into five profiles according to different compression ratios, and each profile is divided into four image formats according to different image clarity, or called level.

3、MPEG-4？

MPEG-4 not only aims at video and audio coding with a certain bit rate, but also pays more attention to the interactivity and flexibility of multimedia systems. This standard is mainly used for videophone, videoe-mail, etc. The transmission rate is required to be low, 4800-6400 bit/s, and the resolution is 176 * 144.

5、MPEG-2 1？

The official name of MPEG-2 1 is "open core" or "digital audio-visual framework". Its goal is to integrate standards, support coordination technology and manage multimedia commerce. Its purpose is to understand how different technologies and standards are combined, what new standards are needed, and complete the combination of different standards.
