Shrinking an ISo Before I'm allowed to Burn it, in order to Fit it onto a DVD

[Datruth77]

Well i used DVD decryptor to make an ISO of a DVD I own.
The problem is the file is 7.9 gigs.....
I didn't realise it at first and i tried to burn it and that's when DVD decryptor said that the file was too big for my 4.7 GIG DVD.

My question is basically i need to shrink the iso in order to allow it to fit on my dvd, before i can burn it.

So how do i shrink the ISO?
Is there another workaround?

I own the DVD so if you want me to re build a new ISO with a new program, i could do that too, but again i'm not sure exactly what to do at this point.


Any help would be good :thanks:

Will it cause a loss of quality?
If it does, is there any other way to shrink it?
I want near perfect quality, if not perfect.
Basically, i'm making a full backup of all my DVD's just in case i lose my originals.

oh by the way, i just downloaded DVD shrink and i tried to burn my ISO, wouldn't let me though.

It said that the file was too big.

What do i do?

Use DVD Shrink to compress its contents...

You simply can't compress a file and expect it to look the same. You can use DVD Shrink in reauthor mode and select a main movie only backup. As long as the movie is under two hours long there will be no loss of quality. You may need to rip the movie in file mode instead of .ISO mode.

How?

I'm really new at this bro, so i'm sorry if i'm being difficult.

Can someone give me a step by step description of what to do?

Do i need to re decrypt the movie using dvd shrink?

:thanks: for the help everyone. :)

Well i tried what you guys said and read that tutorial, and i set it to automatic compression, it's still too big.

It came out to be 4.8 gigs.

So then i went and I tried to Re-Author the movie myself, cut out all the extra junk and only the movie.

It came out to be 4.5 gigs with just the movie and nothing else, and yet the program says the movie is too big for my dvd.

When i read my DVD's size it said 4.7 gigs of space, so i would think it would fit, not sure what's up with DVD shrink.

So basically, i want the full disk, but how do i compress the file even more?

And why is it that when i only wanted the movie and I went to re author it, it told me the file was too big for my disk, when the size of the movie file itself said 4.5 and my blank disk says 4.7?

Sorry for all the questions everyone, thank you sooooo much for your help though, it's been very valuable.

A single-sided DVD is 4.37GB. "4.7GB" is a lie of the manufacturers. They count the GB as 1000*1000*1000 bytes instead of 1024*1024*1024!

To backup your DVD, do a movie-only backup with DVDShrink's re-author mode and try to remove some streams you don't need. In particular, remove all DTS streams, and if possible, the LPCM streams. You can see if the compilation fits on the DVD by looking at the size bar. If there is a red part, you have to remove more material.
If you really cannot shrink the DVD enough, you will have to cut it in 2 parts, but this case is very rare.

What's the duration and the audio streams of the movie?

[Datruth77]

I don't know where the audio stream is located, if you could help me with that it would be much appreciated.

I tried to re author it with just the movie and it's still a bit bigger.

It's at 4.568 gigs right now.

Duration is 2:57:41.

Thank you soo much for your help roiz.

What would you recommend from this point bro?

Under Preferences, make sure you've selected a DVD-5 as a target size. After you load the .ISO, click Re-author, then click the DVD Browser tab. Double-click the longest title under Main Movie, then click the Compression settings tab and set it to Automatic. Uncheck any audio and subtitle streams you don't need (The first audio on the list is the default one that plays). At this point, check the compression ratio. Anything less than 100% means a potential loss of quality, and the lower the number, the worse it will look.

A three-hour movie is going to need a lot of compression. It's probably going to take a while and it may not come out very good. If you want perfect 1:1 quality back-ups of long movies like this, use dual-layer disks or split the movie into two parts. You can set start/end frames or select a chapter at which you want to split it. The green bar indicates how full the disk will be, and if any part of it is red it means the output is too big. If you set it for no compression, you can select only as much of the movie as will fit on a disk and you'll see the green bar not completely full.

When you're done, click File > Backup... and select ISO Image File. When Shrink is done, open and burn that image with DVD Decryptor, ImgBurn or your preferred choice. Your success rate will usually be better than letting Shrink launch and burn it for you.

Thanks for your help CWR03, but looks like i'm going to have to split it.
It just won't compress enough.
So i just decided to keep it at 100% and split it into 2 dvd's.
Thanks for everyones help, hopefully someone will eventually put a workaround.

Nice little explanation, CWR03!
One note though: I wouldn't use DVD Decrypter to burn. It is outdated. Use ImgBurn instead.

Datruth77, indeed, a 3 hours movie cannot fit on a single DVD without a noticeable quality loss. Usually, I consider that a compression ratio of 75 to 85% is acceptable, and more than 85% is almost perfect. Less than 75% is really poor.
But take those percentages with caution. The final quality depends greatly of the quality of the compression of the original DVD, and of the presence of tiny details or frequent camera movements in the movie.

There are some exceptions - and it appears to have something to do with digital "filming" and/or CGI.

A prime example is the 2005/2006Peter Jackson remake of "King Kong" - it looks great, even on large screens, after being compressed to approximately 55%...

I agree - I've noticed that the Enterprise series, as an example, was much more compressable than many others with which I've worked. There's very little motion blur in camera pans or quick camera jerks, probably because of the high-end digital photography they used. There's also no film grain.

I just shrunk The Hulk at 42.3% and the quality was perfect. :)
