General description of DVD Rip.

 

To put it simply, all files recompressed and encoded from DVD as original files are called DVD Rip. Use DivX compressing technology on video images of DVD disks for high-quality compression, and MP3 or AC3 technology for audio compression. Then merge the video and audio part into one .avi file and add external subtitle files. In this way, a new generation of video and audio playing format comes into being. Its size is only the fraction of the original DVD, yet the quality is very good. It is typically released as SVCD or DivX/XviD. This is what is called DVD Rip. Because it restores the image and sound nearest to DVD with a relatively small volume, it enjoys hot pursuit by the majority of video enthusiasts shortly after being introduced. When DVD is transferred into DVD Rip, it will lose off some features of DVD such as menu navigation, soundtrack selection, and segment choice. However, the loss is negligible relative to the aspects of its advantages and its convenience in storage and exchange. With the growing popularity of broadband networks, DVD Rip has become the first choice of more and more net citizens with its incomparable predominance. Hopefully in the near future, DVD Rip will be able to take the place of other video formats to be the mainstream of internet video and audio playing.

There are now many available compression codes, among which DivX, XviD, and the recent X264 are relatively popular now. Because they are encoded in different forms, the definition varies greatly. However, not all formats of files encoded with DivX or XviD are from original DVD files, theatre shooting movie or VCD are also able to be transferred to DVD Rip. DVD Rip compressed with DivX, XviD or X264 technology is only approximately 1/10 of the original DVD file.
