Editor to share with you what format mpeg4 refers to, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to understand it!

Mpeg4 is based on Microsoft's MPEG4 v3 standard; its video part is compressed in MPEG4 format with high-definition picture quality comparable to DVD, and the audio part is compressed in MP3 format with high quality.

This article operating environment: Windows7 system, Dell G3 computer.

The MPEG4 format is based on Microsoft's MPEG4 v3 standard. Its video part is compressed in MPEG4 format, with high-definition picture quality comparable to DVD; the audio part is compressed in MP3 format with high quality; finally, the combination of the video part and audio part is enough to make us refreshing AVI files. MPEG4 is one of the network video image compression standards, characterized by high compression ratio, clear imaging, small capacity, a DVD-9 disc, can store more than 10 high-definition MPEG4 network movies.

The MPEG4 video compression algorithm can provide a very high compression ratio up to 200 Group1. More importantly, MPEG provides a high compression ratio with little data loss. MPEG4 is the latest image compression standard proposed by MPEG. It can be said to challenge DVD against SVCD, and its threat to DVD and SVCD is self-evident (some people say it is a DVD killer). It is said that MPEG4 is a coding technology banned from export in the United States. It takes only two CDROM sheets to encode and compress a DVD. And play (decompress) this kind of coding, the hardware requirement of the machine is not high.

The current MPEG4 is not perfect, although in the ordinary picture it can be compared with DVD, but, after all, MPEG4 belongs to a high compression ratio of lossy compression algorithm, in the performance of the film explosion, fast movement and other images, its shortcomings began to be exposed-slight mosaics and color mottles and other common problems in VCD also began to perform here, its image quality can not be completely compared with the MPEG-2 technology used by DVD. It is hoped that in the future, with the production and playback of MPEG4 software to further improve the compression and decompression algorithm to gradually improve.

The above is all the content of this article "what format does mpeg4 refer to". Thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
