Backing up blu rays

How can I (pretty much) losslessly compress blu rays? At the moment I am pure ripping on anydvd - now need something to make smaller

 

Thanks

There is no (pretty much) lossless compression for Blu-ray. Blu-ray already uses efficient compression. If you want to make the files considerably smaller, the quality will degrade.

 

Of course there are plenty of movie downloads available which compress a 30GB movie to 4 or 8GB 1080p MKV files, and the quality might be good enough for most people, but it's clearly not the same as the original disc.

Thanks. Something like 4 or 8 gig would work. How can I do that to my current rips?

As a follow up to this, if I just want to straight rip a DVD (not a blu ray) whats the best option? What, for blu ray, is the best option for straight copies rather than compression?

 

Thanks!

Handbrake is lossy compression.

 

Use MakeMKV for lossless DVD/Blu-ray ripping, if you just want to extract the main title and skip all the menus/trailers/extras.

 

MakeMKV can also be configured to convert Blu-ray audio to FLAC, though it's probably only worthwhile to do that with PCM discs. TrueHD/DTS-HD don't compress as well as FLAC, but it takes a long time to save 1-2GB.
