Video formats can be divided into two categories: local video and video suitable for local playback and network streaming video and video suitable for playback in the network.

Commonly used video formats1. Video format: AVI
AVI (Audio Video Interleaved) format is a video format introduced by Microsoft from the Windows 3.1 era. After years of development, it has become very perfect. Its compatibility is very good. Most of the game titles in the computer and the video clips on the Internet use this format. And its picture quality is also very good, much clearer than the more popular video formats such as RM/RNVB. Even with compressed AVI files, the playback effect is significantly better than streaming media files such as RM/RNVB. At the same time, the disadvantage of the AVI format is also obvious, that is, the size is too large, which can be tolerated by users who play it on a computer, but it is very difficult for mobile phone users to accept. But don't worry, by compressing the following software, we can compress a large AVI video to a very small size without affecting the quality (playing on a mobile phone requires far less picture quality than a computer), suitable for Mobile phone users play.

Now what we often say about MP4 video and MP4 in MP4 players are actually concepts after being confused and misled by manufacturers. The earliest MP4 is an improved audio technology based on AAC.

At present, the so-called MP4 video we have seen, its real name is MPGE-4, and its compression ratio is very high, so it saves storage space and guarantees image quality, which cannot be achieved by other technologies. And the image quality is good, the highest image definition is 768 × 576, which can almost achieve the picture effect close to DVD.
