How much compression is needed to fit a retail Blu-Ray onto one of these?
I've seen a lot of people here discussing what they keep their Blu-Ray rips at (mostly people keeping movies on drives), and the number usually seems substantially less than the 25GB number that you can fit on these discs.
So, how much compression will need to be done to fit what is on a standard retail Blu-Ray on one of these? Will it look pretty good?
Can it fit a 1:1 perfect rip without any compression? Probably not.
I made the mistake when backing up DVDs of buying single layer discs, then realizing most of my collection was double layer and pushing 8 GB, and realized I'd have to wildly compress the video to make it work (and DVD is already bad), so I'm just going to buy double layer discs or stick to keeping it on drives. Didn't want to make the same mistake for Blu-Ray. I ended up using the discs for single layer movies.
I'm not sure if 25 GB is adequate for a nice quality picture, or just "ehh". Then the answer becomes if I really want to keep a file bigger than that on a drive anyways and the point becomes moot I suppose and compression is inevitable
Losing quality drives me nuts from a preservation aspect and I like 1:1 copies but I understand there's a point where it is unreasonable to keep such humungous files especially if you are doing so in bulk
