DVD Shrink Image Size Problem

[soneman]

I just need something clearing up.

I've been trying to backup a commercial 6.91 GB Dual Layer DVD onto one 4.35 GB (aka 4.7 GB) Single Layer DVD.

I ripped the Dual Layer DVD with DVD Decrypter and no problems there. The problem is that DVD Shrink creates an image that's bigger than 4.35 GB. This despite me checking the bar at the top was green before I started encoding.

But, after DVD Shrink has finished encoding, I end up with a 4.73 GB image. Which is too big (unless I use a blank Dual Layer DVD).

Is there something that I'm doing wrong here? The green bar says 4,464 Mb which naturally, I thought would fit onto a single 4.35 GB Single Layer DVD.

Open the image up in DVDshrink and run it through a second time.
This should bring it down to the correct size.
I have never experienced this before but have seen a few people mention that they have.
Are you trying to keep the whole contents of the original DVD ?
If so you could maybe think about removing some extra features or just backing up the main movie only.

Because you only need to reduce the image size by a small amount you shouldn't notice any considerable quality loss.
Many people will tell you that the quality will be crap, but I would recommend you try it for yourself before making a decision.

What I'm basically trying to do is to keep all of the special features, the menus and the main movie. But, I remove all of the unwanted audio languages and unwanted subtitles.

So I'm left with a project containing the Main Movie, English Audio, English Subtitles, and all of the Special Features with the menus still intact.

But, as I said above, DVD Shrink creates an image of around 4.73 GB when I set the compression to "Automatic".

I have to set the compression to the lowest possible percentage for the Special Features in order to get DVD Shrink to create an ISO image thats around 4.2-4.3 GB. And that's the problem. The bar at the top says that the image will fit onto a single DVD-R (before I manually change the compression) when in fact, it'll encode an image that's around 4.6-4.7 GB.

Is there a setting in DVD Shrink that allows me to change the size of the green bar at the top? This is where the main problem is.

The inconvenience for me is encoding an image which DVD Shrink says (according to the green bar) will fit onto a single blank DVD-R when after it's finished encoding, the image is too big to fit onto a DVD-R.

Which means I have to delete the new image, manually configure the compression levels myself and then encode again.

This is the only method that's worked for me. It's very annoying, to say the least.

open dvd shrink...edit/preferences/custom then change to 4464 or whatever you want

if not this then...kinda seems like a bug

Tried it and it worked. I set it to 4385 MB which is 4.29 GB.

I have to agree with you though. It does sound like a bug. I just thought everyone should know about this problem as it can be seriously annoying and time consuming.

Anyway, thanks for the help.

I have never had it do that to me

As moontrash posted before, it sounds like a bug.

I just thought I should report here and let everyone know about this bug so that everyone here can work around it.

i dont think there's a bug, i think your setting had been inadvertently changed somewhere along the line.

That's not possible because before moontrash's post, I had no idea how to change the disc size setting.

And I don't know about you but I don't think it's possible for my PC to change the setting all by itself.

It isn't a bug ... and i doubt the settings got adjusted .... the reason this happens is because when you load your dvd files into shrink it does a quick scan and then makes a guess at the amount of compression needed to make the files fit a 4.7 gb dvdr, usually this is all that is needed and shrink gets its guess correct, however if a movie has lots of action scenes shrink may get it wrong because of the higher bitrates used on the original files for these action scenes, to overcome this you should first let shrink do a deep analysis (find this in the file tab) shrink will then adjust the compression accordingly and the resulting files will fit a 4.7 gb dvdr

Makes a lot of sense.

In fact, the film I was trying to backup when this happened was an Action/Adventure movie.

I knew about the Deep Ananlysis feature but I don't use it because I heard it doubles the encoding time.

And I really don't want to be waiting more than an hour for my DVD to be compressed and ready to burn back onto DVD-R.

It doesnt double the encoding time ... it just takes a while to analyse the files (so effectively it doubles the time it takes to shrink a dvd) i only use it if needed i.e. if shrink guesses wrong with just normal analysis (rare) or if i have a movie that i know contains a lot of action scenes

You just contradicted yourself.

You said that it "doesn't double the encoding time" yet it "effectively doubles the time it takes to shrink a DVD".

It either doubles the time it takes to shrink the DVD or it doesn't? Which one is it?

[psx_pirate]

What i said was .. "it doesn't double the compression time" ... when shrink starts its compression operation the time taken will be the same wether you use deep analysis or not ... however it does take a while for shrink to analyse using deep analysis ... its this analysis that adds the extra time to shrink not the actuall encoding .. but ... YES it will take longer to complete the overall shrinking if deep analysis is used

sorry if my last post was a little confusing ... hope this clears things up

Thanks for clearing that up.

I will take that into account the next time I need to backup an Action/Adventure DVD.

really it's worth the extra time to do it for all your movies.

DVD Shrink is doing a damn good job as it is at the moment. And shrinking my DVDs mighty fast at that.

I dont know what setup your using but when I use shrink I always use the deep analysis. With analysing, encoding and burning I'm looking at about 1 1/2 hrs tops. The results are much better.
You may not see the difference now, depending on your tv, but I bought a 42" plasma about 9 months ago and the non deep analysis dvds were horrible.
With the price of this hardware coming down all the time I would recommend using the deep analysis so that you can still watch the movies in the near future.

OK. I've just checked out your pc. The deep analysis would effectively double your entire time at least. 256mb is just not enough. my old intel celeron 1800+ had 512mb ram and the deep analysis doubled the entire time.

As I said before, I really don't have the time to be waiting around for my PC to compress a DVD.

So do it overnight the way I do. Start the process just before you go to bed and by the morning it will be finished.

Well, this is the fastest PC I own.

I do have a laptop but it's vastly inferior to my PC. I think the specs for my laptop are like 266 Mhz processor, 64 MB RAM, 5 GB Hard drive.

So you see, this is the best setup I can manage.
