This article is about the differences between mpeg4 and mp4 formats. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

The format of mpeg4 is different from that of mp4; mpeg4 is a coding standard, which is mainly used for online streaming, optical disc, voice transmission and television broadcasting, while mp4 is a file format and a set of compression coding standard for audio and video information.

There are differences between MPEG4 and MP4. The specific differences are as follows:

1. MP4 is a file format, while mpeg4 is a coding standard, the two are not the same concept. It can be understood that mp4 is a standard audio and video file that supports mpeg4, and there are many file formats that support the mpeg4 standard, including mp4 and avi.

2. MP4 is a set of compression coding standard for audio and video information, which is formulated by the moving Picture expert Group (MovingPictureExpertsGroup) under the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). The first edition was adopted in October 1998 and the second edition was adopted in December 1999.

3. The main uses of MPEG-4 format are online streaming, CD-ROMs, voice transmission (video calls), and television broadcasts.

4. MPEG-4 includes most of the functions of MPEG-1 and MPEG-2 and the strengths of other formats, and adds and expands support for virtual reality modeling languages (VRML, VirtualReality Modeling Language), object-oriented synthetic files (including audio, video and VRML objects), as well as digital rights management (DRM) and other interactive functions.

Extended data:

Characteristics of MPEG-4

1. Different coding algorithms can be used for different objects, so as to further improve the compression efficiency.

2. The objects are relatively independent, which improves the reusability of multimedia data.

3. Allow users to operate on individual objects, providing unprecedented interaction

4. Allow flexible allocation of code rates between different objects, allocate more bytes to important objects and fewer bytes to secondary objects, thus achieving better results at low bit rates.

5. It can easily integrate natural audio and video objects and synthetic audio and video objects.

MP4 (also known as MPEG-4) is a kind of MPEG format, which is a compression method of moving image. Through this compression, smaller files can be used to provide higher image quality, which is one of the most popular video file formats (especially in the network).
