Does DVD-RB 'process' files even at 0% compression like DVDShrink does...

At no compression will DVD-RB process/alter the file at all like some say Shrink does? Or will it make a true 100% 1:1 copy like decrypter does....?

Thanks!!

 

what is the reason you are encoding them if no compression is needed than all that is needed would be dvd decrypter.

but to spend any time encoding/transcoding you will lose some quality but imho you will alway's get better results w/ the encoders (rb)

 

there could be a good reason NOT to use dvddecrypter and still deal with no compression

think about omitting certain audio streams for example

this way a dvd might fit to dvd5 but because certain data are being left out no compression might be needed

+++++++++

back on topic: i wouldnt know how rb deals with cases like these - never happened to face this scenario

 

@marlin, I use RB a lot...one of my primary programs. I have used it even when no compression is needed. The reason was that I was converting 4:3-16X9 letterbox (primarily changing non-anamorphic letterbox to anamorphic), in this case the encoding was needed due to the fact that it was changing the movie. It even tells you that no compression is needed, hence no encoding as well...do you want to continue anyways, I always answer yes...remember changing from4:3-16X9. It looks awe-some. I have also used Rebuilder to make just basic backups. Even no compression or when ask about the compression ? I asnwer no which moves the RB into the rebuilding stage and then it prepares an ISO image and Video Files folder to be burned with burning software. Just my experience. I'm like I8nights, that if no compression is needed...decrypter does agreat job as well as many other programs. Just wanting to help.

Hey no prblem hanks for the reply!!

My problem is that, I want to burn a movie in which the MAIN movie files fit at 0% compression, but ONLY if I remove french 5.1... so I can't just bunr it as an iso file in decrypter...

so I am just wondering if me remving the audio track and then using RB will alter the movie files in any way

Thanks again!!

 

I just tried decrypting in faile mode, then opening in RB and hitting prepare... and it says "Illegal Source VTS1 Missing"

That's wierd... all I did was going into decrypter aand hit main movie and IFOs and then decrypt..

Any ideas?

 

@marlin, I typically place the movie on HD, using file mode and the entire disk...then open Rebuilder (I'm a movie only guy!) and allow Rebuilder to handle the portion of placing just the files that it needs in order to function, when I see the audio streams I will then disengage the streams I do not want. Hit Back-up (1 click mode) and Rebuilder does the rest. I use to try Movie Only files in decrypter, but Rebuidler wouldn't take it. I like having the Movie on HD that way theres not issue of using the Dvd Burner/Drive throughout the process. I have done it that way as well and it worked properly (I have anydvd running in the background!). Hope this helps.

Cool, thanks for the replies!!!

I am slowly getting the hang of things.... and appreciate all the help you guys give!!

Thanks!!

Thanks vurbal... thats exactly the response I was looking for!!!

 

Vurbal, I don't agree that Shrink's uncompressed format does not alter the files. Besides the fact that many users agree that Shrink changes the files even when uncompressed, I tried it myself. After Shrink, I used RB/CCE 4 passes and the DVD still ended up with pixelation (or "mosquito effect") near the color edges. This is the nasty signature of Shrink. If it didn't alter the files under no compression settings, I wouldn't need Remake.

 

for those that think shrink alters when reauthoring a title uncompressed it would be useful to offer something other than your opinion or perception. I do know that while encoding shrink uses 1 fairly unique matrice for all quality settings. It is a combination of fox high high in the upper box and high_medium in the lower box.
All shrink reauthored no comp titles will retain the original matrice(s) So if its not reencoding then what is shrink doing to "alter" the files? (other than not maintaining 32k gap between video ts. ifo and bub

 

i've run more than one title through rebuilder first and then used the output files with shrink

nothing was changed in shrink

output was *backupped* via shrink again and guess what:

shrink DID change the source material in terms of file size (material was reduced slightly)

so please stop assuming shrink would NOT alter anything

 

while it's true that reprocessing a video ts uncompressed over and over in shrink will cost you 4kb in the last vob each time that in no way means that the previous 4 million+ kb are any different than the original source. I'm not going to do the math but I'd estimate you'd have to repeat the process 100-150 times to lose 1 sec. at the end. i don't think this qualifies as Alerting it just something shrink does and is of no consequence

 

fyi: i'm talking about some 53.000kb from ONE process with 7 vob files


++++++++++

of course i'm not implying that shrink would have an impact on the image quality

but saying shrink does never ever alter files is bs

 

I quess this is going nowhere but I just did the same video ts 4 times and each time lose 4 kb in the last vob. this is with a source less than 4.3GB as in a split. To see what you were doing I ran the complete movie(deer hunter se) twice In this case the sizes are exactly the same size with 7 vobs 1,048,574kb and an 8th 703,212 and i'm willing to bet if I run it again it will be 703,212 or maybe
703,208 so where your 51,000 went is curious to say the least

 

that's why i emphasized: *NEVER EVER*

i have recently had two titles where this happened and i bet there will be 2 more (talking about a 4 disc set)

 

I won't elaborate and I'm not here to argue but I used to use shrink set at no compression as a ripper and to edit the folder and then run it through dvd-rb but noticed on some scenes the background was unsteady or jumpy (for lack of better words) from the foreground. I played back each stage from ripping to encoding from my hdd and determined the problem to be at the initial rip with shrink. I ripped the same dvd with dvd decrypter and played it back from my hdd and the problem was gone. I now use only dvd decrypter and dvdremake to rip and edit my folders and have had no problems since so I say yes dvd shrink does process (alter) files even set at no compression but I have no way to prove it. I don't know about dvd-rb/cce at no compression.

If you only need to remove an audio stream to make a folder fit on a dvd5 then you can rip with dvd decrypter in file mode and use dvdremake to remove the audio stream then use nero to burn the folder.
