DVD Shrink

What is DVD Shrink?

DVD Shrink is software to backup DVD discs. You can use this software in conjunction with DVD burning software of your choice, to make a backup copy of any DVD video disc.

DVD Shrink will also burn your backup DVD, if you have installed the latest version of Nero. You can download a demo version of Nero here. If you already possess alternative burning software and prefer to stick with it, then you can still use DVD Shrink. The output from DVD Shrink can be saved as files on your hard drive, or as an ISO disc image on your hard drive, which you can then burn with software of your choice.


Why use DVD Shrink?

Most DVDs are designed to prevent you from making copies.

The first preventative measure is encryption. Commercial DVD titles are often encrypted, which prevents you from either copying them to your hard drive, or if you manage to do so, being able to play the resulting files. DVD Shrink overcomes this problem with built-in decryption algorithms, which means you can use DVD Shrink to backup a DVD directly, without requiring any other software.

The next problem is not so easy. Most DVD video titles are simply too large to fit, without modification, onto a single recordable DVD-R disk. DVD Shrink overcomes this problem by compressing or "shrinking" the data from your original DVD. The latest DVD Shrink 3.2 contains state-of-the-art compression algorithms, rivalling those found in the best commercial softwares.

DVD Shrink also allows you to re-author your DVD. You can make your own compilation from one or more source DVDs, or select only the parts of a DVD which you intend to view, thus preserving more space on your backup for the highest quality viewing.

Last but not least, why use DVD Shrink? Because DVD Shrink is free.

Quality Settings

DVD Shrink will typically have to compress your DVD so it will fit onto a DVDR recordable disc. Depending on the original DVD and the amount of compression required, the video quality of your backup may suffer. Although the default compression algorithm usually provides adequate quality in typical viewing conditions, DVD Shrink 3.2 offers you various additional options which may improve the quality of your backup.

These options are available in the Backup window:



Deep Analysis

The deep analysis option will encode your DVD in two passes. This will take significantly longer, but it serves two purposes:

1. It will improve video quality by allowing DVD Shrink to better distribute the required compression throughout the various scenes in your DVD.

2. It will ensure that DVD Shrink accurately meets the target size.

This option will be disabled if you already performed a deep analysis of the same DVD. DVD Shrink will remember the results of previous analysis, so there is no need to do it again. This option will also be disabled if no compression is required.

Compress video with high quality adaptive error compensation

When video is compressed, small errors or artifacts are introduced. This is an unavoidable consequence of video compression, and DVD Shrink cannot prevent this from happening. However, it can keep these artifacts to a minimum.

This option will adaptively compensate for any artifacts introduced by the video compression, so as to prevent them from propagating into the next pictures which are compressed. This requires DVD Shrink to dynamically decode and compare both the original and the compressed video, so that it can detect if artifacts have been introduced and compensate for them accordingly.

AEC (adaptive error compensation) requires a lot of CPU power, and depending on the speed of your computer, it may take an hour or more to complete your backup. However, it will often provide a far superior video quality. AEC will also benefit from deep analysis.

If you enable AEC, you can select from the following modes:



The default option is Sharp, which will tend to preserve the sharpness of the original video. This may be at the expense of fluidity or smoothness, where individual frames of the video are perceived to blend smoothly together. Video compression, like many other things, is all about compromise.

Which settings should I use?

If you are concerned about speed, then you need not enable any of these options. Your backup will be completed as quickly as possible, and you may be perfectly satisfied with the output quality.

If you are concerned about the quality of your backup and you don't mind taking a longer time over it, then the best results may be obtained by enabling both deep analysis and AEC options.

Depending on the source DVD, the quality of your viewing equipment, and the amount of compression required, you may prefer either the smooth or sharp options. Please take the time to try one or the other and determine which is best for your backup.

Try and use less compression!

Please remember: there is no substitute for less compression. You can minimize the amount of compression required by disabling unnecessary audio and subpicture streams, by setting some extras to still image or still picture compression, or even by re-authoring your DVD and keeping only the main movie. You will often find that little or no compression is then required, and the video quality of your backup will be indistinguishable from the original.

Also bear in mind that you can redistribute the required compression among the various parts of your DVD. For instance, you could set Menus or Extras which you rarely watch to maximum compression, and this will preserve more space (and therefore more quality) for the main movie.
