What's wrong with DVD Shrink?

Over the course of the past couple of years DVD ripping techniques have changed dramatically. Newer "one click" programs have made backing up a DVD a fairly simple process... but there is a significant trade-off. The quality that can be attained by even the best of these programs is poor in comparison to original techniques that used Cinemacraft Encoder, HC Encoder, QuEnc, or other top-notch encoders. The reason is simple. When using one of these encoders the picture is rebuilt from scratch and optimized for the resulting bitrate. One-touch transcoders usually drop DCT coefficients or change quantization info in order to lower the bitrate. This can result in pixelation and poor overall picture quality.

But, they sure are convenient.

That's where DVD ReBuilder (DVD-RB) comes in. This program was built to bridge the gap between the incredibly easy but limited "one-click" solutions and the incredibly complex but high-quality methods of DVD ripping and backup.

Another advantage of DVD-RB when compared to older methods is that it doesn't require access to an expensive authoring package. DVD-RB includes its own reauthoring engine that reconstructs the DVD in a way compatible with its original design.

What's the difference between DVD Shrink and DVD Rebuilder?


DVD Shrink is a transcoding program. Transcoding or more specifically Compressed-domain Transcoding means normally a re-encoding process that changes the video or audio features, such as resolution or bitrate, by changing parts of the a/v content, but not by reconstructing the content again (which is the case in encoding process). Compressed-domain transcoding also maintains the format of the file same as in the original file. Transcoding doesn't encode it takes out small bits of detail to make the DVD video smaller. Faster then encoding.

DVD Rebuilder can be used as both an encoding and transcoding program by using different modes and is a good program to re-encode a DVD. Encoding is the process of changing data from one form into another according to a set of rules specifiec by a codec. Often the encoding is done to make a file compatible with specific hardware (such as a DVD Player) or to compress or reduce the space the data occupies.

Encoding will give you a better picture quality when you need to 'shrink' your original DVD down to a very low bit rate
