[QUOTE=glenns;158972]The reason a 17 gig full 3d main movie looks as good as a 50 gig 3d is because it isn't compressed just the other stuff from the full disk is removed so the main movie really is only 17 gigs in size perhaps it's a shorter movie than 2 hours so the size is smaller to begin with.With this said your seeing the exact same uncompressed picture with main movie full 3d as you are when watching the 50 gig iso.
You have to remember the 3d movie contains the full blu ray plus the ssif files for the second eye so there's a lot more information on the disk.If you compress too much you will not like the results as they can have the hd audio that takes a lot of room also along with the subs.[/QUOTE]
Exactly. So when making backups of my movies, I'd want the smallest files I can get. (with the best quality) I don't need audio from different languages, subtitles in languages that I can't read, director commentary... etc.
I just ripped my 50GB Hotel Transylvania, compressed the whole disc to 25GB, then from there ripped out the Main Move with the correct soundtrack.
End result: 15GB. 3D looks super on my 1080i tv and projector.
Once again, just my own anal-ness on trying to get the best quality down to the lowest sizes for network storage.
So, on a shorter movie taken down to 15GB, (which is really the same as the end result on the 25GB full disc) is more than adequate.
On real long 3D movies (like The Hobbit) I would just follow how the movie was released... Movie broken into 2 Discs - and compress each disc to 25GB for best results, instead of trying to slam the whole movie together on one disc.
I want small files.. but I still want the picture to look crisp in 1080i
I tried doing the best quality possible on a .mkv SBS in the past, and the one angle (not sure if it is left or right) is just so downgraded in SBS that it looks bad, makes text look bad, etc...
