DVD rip

from Wikipedia, the free encyclopedia

A DVD rip is the transfer of video and audio data from a DVD to another storage medium (usually initially on the hard drive of a PC), which can also involve circumventing copy protection mechanisms ( ripping ).

The term DVD ripping, also known as DVD ripping, came up in the movie pirate jargon at the beginning of the 21st century , when the DVD format itself was still relatively young. Today it is a common name.

With a DVD rip, either the entire DVD, the main film or only certain elements are copied to the hard drive for further processing. Further processing directly from the DVD would also be possible, but this can result in lower processing performance and greater stress on the DVD drive. Since most video DVDs are copy-protected, so-called on-the-fly decryption drivers (copy protection crackers) such as Slysoft's AnyDVD are also used. However, the use of such copy protection crackers is punishable in some countries, provided that a technical protection device is circumvented and this is not done exclusively for personal private use.

Corresponding encoder software, which converts the data, is usually used for further processing . The most common container formats for creating DVD rips are the AVI and MPEG formats, with the most popular codecs used for the process being H.264 , Xvid and DivX . In the meantime, however, the Matroska container format is also gaining increasing popularity due to its capabilities (e.g. subtitles and chapters).

Often a film file should be created that is much smaller than the original medium and yet loses as little quality as possible. The smaller the target file, the more savings must be made in terms of video and, if necessary, audio quality. In general, additional data from the original, such as menus, extras, alternative audio tracks, subtitles, etc., are omitted when ripping, so that only the actual film is processed further. In many cases, this is also due to the fact that only a few container formats can store data such as menus and bonus material.

DVD copy

A DVD rip does not necessarily involve conversion to another video format. To create a copy, it is usually necessary to “rip” the files on the video DVD to the hard drive beforehand.

Since most original DVDs often have a total size of over 4.5 gigabytes (DVD 9), the data size is reduced by recoding until they finally fit on a commercially available single-layer DVD (DVD 5). Although so-called double-layer DVD blanks can be used to make almost exact copies of film DVDs, many users often opt for recoding due to the high prices for such blanks and possible compatibility problems. Special video software programs such as DVD Shrink , DVDFab or Nero Recode are used for this. By omitting audio tracks, subtitles or additional material (menu, interviews), recompression for the main film may be saved, or only a slight compression may be necessary.
