Backup 7.64 GB DVD to 4.7 GB DVD+R

[guitarplaya08]

I would like to back up a dvd but the dvd is 7.64 GB and the dics are only 4.7.

Do I copy it to my hard drive using DVD shrink so it will resize it to 4.7 GB then burn it to a disc?

The problem there is quality is lost.

Are there 8 GB DVD+R discs?

if I try using nero's disc copier will it work?

what else can I do?

thanks a ton

Firstly, using DVDShrink for your back-up will be fine, unless you MANUALLY over compress it, you will not notice the difference. Yes there are now DVD+R9 discs but you also need the burner to burn them with.


Thanks

i have a dvd burner and after backing it up with DVDSHRINK i can burn it to a dvd+r and it works fine quality is just lost

is there a way to do this without losing quality?

if i have a 7.64 gb dvd and a 4.7 dvd+r then I can't use the disc copier, correct?

Quality is lost doing it this way... the question is, is that quality loss noticable ???

I and many others here think not. Those that do either have a DL burner and DL media (@ approx$15 a pop) or split to two discs - main movie on 1 and extras on the other.

Let me reiterate that quality loss is only a problem if it is noticable.

[guitarplaya08]

so no matter how you back up DVD's quality will be lost..

yeah its noticable

urrr, no ?

No quality loss using either of these methods.

What differences are you seeing/hearing ?

What equipment are you watching them on ?

Are you using Deep Analysis ?

Are you removing foreign languages ?

[guitarplaya08]

The audio is fine i just see more pixels when I stick it in my television..

the tv is a Akai VHS/DVD Combo

whats deep analysis?

and yes i removed foreign languages


wow for 15 bucks a disc you might as well buy the dvd new again

Quality is subjective... what I think is still pretty good you probably think is crap. Unfortunately there is no real way around this apart from the methods I have described previously. What you need to do is possibly try another transcoder apart from DVDShrink (DVD2One is generally regarded as its equal) and see if your results improve.

The other thing to note is that it could just be this particular disc that won't play the game. Then there's the true doyen's method of demuxing everything, re-encoding and then rebuilding the DVD. It all depends on how far you want to go.

If worst comes to worst, either spend the money on DL discs, learn how to split movie and extras onto two separate discs or just buy yourself another copy if you scratch this one.

whats deep analysis?

Deep Analysis is a feature of DVDShrink - in plain english it attempts to make the picture better. Some movies it has great success on, others not as good. The full explanation of how it works has been posted in these forums a few times and talks about vectors and things like that. I think it would be over your head a bit so I've simplified it

What version of DVDShrink are you running ?

wow for 15 bucks a disc you might as well buy the dvd new again

At this stage. Like anything though, give it 6 or 12 months and they will be down to a more affordable price.

I would recommend DVDrebuilder. It will take much longer, but it will also produce a better image. I now only use a transcoder (dvdshrink or the others) if the compression will be more than 70% of the original. If it list it as 70% or less, I now use DVDrebuilder

Check out this guide. It's complicated, time consuming, but you can't beat the quality

Sorry, wrong guide. This one is newer

No matter how you go about it, your going to have to compress some data at some point. Even using the best methods known, you still have to remove items.


guitarplaya08:
I don't know what's going on with your experience with DVDShrink but, I have a 36" 100mhz TV and run my DVD on the S-Video socket and I can't see any difference between my original and copy. Even on long films, there is still no noticable difference in quality. I am guessing that the original material is DVD quality to start? If it's low in quality to start then maybe there is a larger or more noticeable degradation on transfer. I used to spend around 7 hours on one single DVD back-up until I found shrink. I have backed up the same movie by both methods. The two copied discs are of the same brand, have the same amount of data byte for byte on them and the quality, in my opinion is identical.

Depending on the disc, there can be a noticeable difference between the original and backup using DVDShrink... whether the difference is enough to be annoying is a separate thing.

To try to improve the quality, remove all the extraneous stuff which you don't think you want (it's a backup after all right? you still have the original) for regular viewing like trailers/extra soundtracks and usually you can signficantly reduce the further compression needed on the main movie.

And deep analysis is a must.

I don't use it to rip, just to re-encode, but I think it will...guides to the left
If you rip the menus, it will have them in the finished product...
Sorry, I don't use Nero all that much, but Nero will burn the files to a DVD yes

There will be without a doubt a loss in quality, it would be impossible not to. My point is that it is not noticeable when viewing under the same conditions as you would normally view a DVD. In my opinion most of it comes from the fact that people hear the words compression and shrink and then get it into there heads that there will be a picture loss. If you are getting a massive loss of quality when using programs like shrink, then you are doing something wrong. Short of sitting 2 inches from the screen and counting every pixel, and hanging on every frame waiting for a noise block, you won't notice the difference

[vitualis]

I didn't say that there will be a massive loss of quality. But there can be a noticeable difference. You cannot categorically claim that you won't notice the difference, and I assume that you are only speaking from your OWN experience.

I can easily tell the difference between my original STTNG discs and my backups -- but the backups are still perfectly watchable. Of course, it may make a difference that the STTNG discs have over 3 hours of full frame video per disc so the original bitrate wasn't that high to begin with.
