We all know DVDs. It is an excellent media format for household video watching. It adapts MPEG2 video encoding and AC3, DTS audio encodings which ensure the high quality of DVDs but have a shortcoming of too big file size. One DVD cost us almost 4.7G to store. It is easy to learn that it’s no sense to spread DVD files via Internet due to the current conditions. It will cost huge resources to upload DVD files onto the host servers. Nor do we want to download a video file with its size of as many as 7G. Not to mention that we will not save them in our hard disks.
Here we get DVDRIPs. It can separate video stream, audio tracks and subtitles from one DVD file and compress them or do other processes. It then combines them into one single file with much smaller file size and almost the same quality as the original DVD file. We have software like WinZip or WINRAR to do similar jobs on ordinary files. If we want to make DVDRIPs by ourselves, we should use professional encoding software.
To rip a DVD there are three steps. The first is to use MPEG4 to encode the video stream. Secondly, to compress audio tracks through using MP3 or DTS codecs. The last is to draw out subtitles.
Now we have got some basic knowledge of DVDRIP so we can start to make it. DVDPean Pro is a kind of DVDRIP making software that supports almost all popular video and audio formats. It has a powerful function of converting DVDs that it allows users to modify the parameter of converting. Those users with relevant encoding knowledge can make a DVDRIP whose quality is wonderful and file size is acceptable. It is recommended to fine tune the parameter of video codec and the bit rate. The former has relations to the file size and the latter is very important to the video quality.
