I know no doubt this has been brought up before, but i'm looking for some side by side evidence, ie a screen shot using dvd shrink angainst say clonedvd or dvd2one.
i've been using dvd shrink and record now to burn very happily, but after doing a few copies it becomes more and more evident that the colours are not even close to the original, even when it's not compressed.
I recently did a backup of my Ghost In the shell dvd, using dvd shrink, no compression, dvd was small enough, and used the high/slow quality setting. And indeed the people are sharper than the original, but the colours compared to the original is shocking, with a normal movie it's not so noticeable, but the colours on an original dvd are amazing, i used to own ghost in the shell on video, and the dvd is like reading a manga comic hot off the press, yet with no compression the colours look really faded, a lot more white.
I'd understand if it was being compressed, colour will be the first thing to go, but no compression with deep analysis on is disapointing.
SO i refer back to my original question, can anyone out there show me a better compression technique, i read a lot of the posts by the regulars, the dudes who know what they're talking about, you know the ones...
And even in their posts there is no definate preference.
Thank you in advance
Bailey

If there's no compression then the video should remain completely unchanged.
It does in DVD2One, I don't know about Shrink but it makes no sense to compress it if it's going to fit anyway.
If it's going to fit without compression then just rip the movie only with Decypter, this most certainly doesn't alter the video at all.

If you don't need to compress, select "no compression" and don't do the deep analyses (why deep analys something that isn't even going to be encoded!!)
I've not seen any diffrence in colors on my backup disks.

Yeah, i'd never seen a difference either until i started doing my manga movies, i'm sure the colours aren't as bright and full.
But maybe i was just stoned...

Hi all. :)
In the 50ish backups I have made with DVD Shrink v2.3 and v3.0b5 (some being animations), I have never seen any alteration in colour content.
"But maybe i was just stoned..."
Maybe you were. ;)
Best wishes for the new year to you all. :)

I Concur, If there is no compression then there is absolutely no change in the Video Information so there should be no change in Quality...But if you are Not happy when there is compression then you can try a manual Backup Method Like I do were you use a Real software encoder to compress the files and then Rebuild the DVD in a DVD authoring Program..The Compression Quality with an encoder Like CCE is Far superior to the compression By DVD2One or DVD Shrink, I have even gotten 2 90 minute Movies on a DVD with better Quality useing My Method than DVD2One can do Backing up Just one Movie when there is Compression..This Method is difficult to learn but the Quality is awesome and you get to use other DVD stabdards That allow you get up to 6+ hours of video on a DVD.......Cheers

i noticed that DVD2One causes some pixillation and macro blockyness, but that the colors come out the same. i have also noticed that the DVD Shrink copies are just as sharp as the origional, but the colors appear greyer. corners and edges appear pixillated on DVD2One copies, but the corners are the same on DVD Shrink movies.

Hi there, when an original movie fits on a DVD-5 disc I always use Alcohol 120% to make a perfect one-on-one copy together with Anydvd. Even if you do not have 2 dvd drives with Alcohol you can make an image of your movie and then burn it. No quality loss. DVD Shrink works perfectly for me but don't forget even an original movie will show pixelation and square like parts if you watch the movie on a medium quality TFT monitor with 32 bits colour depth set. Its inevitable, I guess. On the other hand of course there are more professional softwares for transcoding but the question is how much is worth the effort for a movie you'll watch every now and then while most of people watch them still on TV sets where even divX looks great. As for me DVD Shrink is the only tool that satisfied me 100% and believe me I've tried them (almost) all.

backing up a dvd is not like backing up say, a videotape, where you lose video information in the process. if there is no compression when backing up a dvd, you are going to get the exact combinations of pits that the laser reads. there is no way there would be a degration in color.

dvd shrink COMPRESSES the dvd video- so there is quality loss. Also- obviously you dont need shrink for a DVD-5, but like 3 out of 4 DVDs are DVD-9.
i think i know why DVD Shrink loses color quality, it retouches the movies, thats why you dont notice pixillation,but do notice color difference

pcshateme, do you notice this difference in color quality when doing a comparison using WinDVD?
If yes, do you have two WinDVDs opened so as to do a side by side comparison?

Minion, i read with interest ur comments on CCE, do you know where i can find a tutorial on its use, cos it looks v.complicated? can't see any on the Cinema Craft site.
Is there a user guide with the trial version under the software tab on this site.
Cinema Craft Encoder SP (CCE) v2.67.00.20 Trial
as an avid DVD Shrink user, i am finding more of my longer films to be a pain, even after stripping extras, foreign audio and subs, i'm still left with a huge red overflow.
for quality reasons i try not to compress more than a setting 5 which i think is a 25% comp ratio. to fit the longer films on and indeed sometimes 2 would be xlnt.
will give the trial software a go anyway.

here's a guide
There is a program that does all of this for you I have it at home, it's called DVD2DVDR or something. I can check later.
Points to note that may not be in the guide.
Almost all Commercial DVDs of films are Progressive despite what bitrate viewer may tell you so tick that box.
Leave the Top field first box unchecked, CCE always encodes TFF anyway.
