Common video formats
ASF
ASF is the abbreviation of Advanced Streaming format. From the literal meaning (Advanced Streaming Format), you should see the usefulness of this format. To put it bluntly, ASF is a file compression format developed by MICROSOFT in order to compete with the current Real player to watch video programs online! Because it uses the MPEG4 compression algorithm, the compression rate and image quality are very good. Because ASF exists in a video "stream" format that can be viewed on the Internet in real time, its image quality is slightly worse than VCD, but it is better than the RAM format of the video "stream" format. However, if you do n’t consider spreading on the Internet and choose the best quality to compress the files, it is not surprising that the video files generated are better than VCD (MPEG1), but in this case, you lose the original intention of ASF development It is better to simply use N AVI or DIVX. However, Microsoft's "Zidi" has its unique advantages. The most obvious is that all kinds of software support it.
n AVI
n AVI is the abbreviation of newAVI, a new video format developed by an underground organization called ShadowRealm. It is a modification of the Microsoft ASF compression algorithm (not the imagined AVI). The video format pursues nothing more than compression ratio and image quality, so in order to pursue this goal, NAVI has improved some of the deficiencies of the original ASF format. , So that NAVI can have a higher frame rate (frame rate). Of course, this is at the expense of ASF's video streaming characteristics. In a nutshell, NAVI is an improved ASF format that removes the characteristics of video streaming! To make it simpler, the non-network version of ASF!
AVI
AVI is the abbreviation of Audio Video Interleave. This does not need to be explained to me. This old video format published by Microsoft in the era of WIN3.1 has been serving us for several years. If you don't know this, I don't think you should look down.
