What’s the difference between the DVD Shrink3.2 and Rebuilder?

[coody]

I want to test the easy and quality of burning a dual layer DVD movie but have to fit it to DVD-5 first. What’s the difference between the DVD Shrink3.2 and Rebuilder? Which one is better and why assuming the original source DVD disc is new without problems?

Shrink is a transcoder, fast, ok quality under 80%
Rebuilder is a encoder, much slower, better quality

[fritzi93]

Re-encoding is a lesser of two evils proposition. There's some quality loss when re-encoding MPEGs. However, quality loss when transcoding has nothing to do with lossy codecs. A transcoder actually "throws away" DCT coefficient data, essentially error correction data. Look here for more:

You cannot say that.
A reduction of 50% in a Superbit disc can look better than 95% of a poorly encoded disc.
The % is based off the source quality.

Rebuilder automates an encoder.
Shrink is a transcoder.

My comments were generalized, so give me a freaking break...
How many damn people talk about superbit DVDs in the first place? I see one post in the last year! in this forum

Shrink can also skip any transcoding and just create and iso, so your last comment is wrong.

Care to add anything else that really wont help the OP?

OK OK easy does it.

It is true that Shrink is a self contained transcoder, but DVDRB is not an encoder... It is an interface tool that can utilize several different encoders - CCE, HC, Quenc, etc.. You have to direct it to an encoder. DVDRB provides an easy way to backup DVD discs through encoding, which is, in almost all cases, superior to transcoding. Fritzi is correct in that transcoders throw out information in order to achieve compression, while encoders do not.

With the speed of todays processors, the time it takes to encode is so greatly reduced compared to when DVDshrink was still being developed, that I almost entirely choose to encode (regardless of compression) rather than transcode.

DVDRB is a highly versatile tool that allows you many options for encoding, that include using avisynth filters, choosing matrices, cropping, blanking, etc..
