Shrink Blu-Ray to fit 25Gb BR-R

Hey guys. I was wondering if there was a program like DVD shrink but for Blu-Ray so that I can fit on a 25GB BR-R disk. I have read that there is a thing called Blu-Ray rebuilder but still in beta and from what I read it is no good. Hope someone knows. Thanks a lot.

Ty so much guys. This keeps like the menu intact right? Quality will go down?
Answer #4
No you lose menu it will make a BMDV folder and you click/drag it to imgburn and it’s just the movie with chapters but it’ll fit on a BD-R
Answer #5
Well, is sort of right.. You can do movie only OR full disc (with all the menus and stuff).. BUT by keeping all the bluray fluff – the idiotic “making of” and the poser sound man saying why he chose this “bamf” sound over a “bumf” sound, thet all take up room.
And it’s room you’ll need to get the best quality out of the shrink.
Like this:
Original blu = 50g, 40 movie, 10 crap.
New blu = 25G.. do you want ALL that 25 going for the movie (40 down to 25) or whole disc (40 down to 20 with 5 for the crap)??
I ALWAYS chose movie only.. I generally hate the self-obsessed rubbish these elitist poser cram onto a bluray!

Next question:
YES, you will lose SOME quality – you’re going from 40 gig movie file down to 25 gig movie file, and that saveing has to come from somewhere.
Usually what happens is a tighter restriction of the encoder, maybe a wider gap between key frames, etc – generally you won’t notice any difference.
Where you might notice it is in long periods of high action scenes or scenes where there is a predominance of one colour (usually black, because it recodes to a blocky grey-black). This is less likley to occur on a movie only copy because of the extra room available.
A few years ago I did Expendables 1 – it’s perfectly watch-able on a 55″ screen from a BD25. If you really look for blocks, you will see them but immerse yourself in the movie and you won’t notice them.

You could also use BD rebuilder like I do.
