Briefly speaking, all files that make a re-encode to DVDs are called DVDRIP. The core technology of DVDRIP is separated to three parts: Make video compression by using Mpeg4 formats, make audio compression by using MP3 or AC3 codecs and make the subtitles by using some relevant software. There are many codecs that can be used to make a video compression. The most popular among them are DivX, XviD and X264 which was announced recently. As the codecs are different between each other, the quality of videos that are encoded is not the same. Generally speaking, the X264 codec combines the advantages of file size and video quality and are said to be the mainstream of encoding in the future. The only shortcoming of this codec is that it costs many system resources to be played on either PCs or portable media players. The DivX and XviD codecs do not need to use original DVD files. The DVD files can be several times smaller after the re-encoding with DivX or XviD codec. Because of the file size and relative high quality, DVDRIP has been welcomed by many people. The DivX and Xvid codecs are generated from Microsoft MPEG4.
