I've tried it on my two discs, Blade Runner 2049 and Ex Machina and it works. But, you have to have certain Blu-ray drives to do it - including the Asus BW-16D1HT.
Got a tip for us?

MakeMKV now does 4k UHD rips

Are you saying, that you get viewable, de-AACS2.0-ed movies?
Last time I checked, they only were able to produce 1:1 disk image as a backup.
Yup, viewable 4k movies in your favorite player. The only caveat is whether decryption keys are available so you have to put a file with these (keys_hashed.txt) into MakeMKV's data directory (~/Library/MakeMKV is default).
OK, I see.
I tried to put that file into ~/.MakeMKV as I thout that was it's default data directory...
Must check this again.
As noted above you also have to have a "UHD friendly" drive. These are essential blu ray drives that are able to read UHD discs but don't officially support UHD playback or AACS 2.0 and this along with the disc keys allow AACS to be circumvented somehow. I don't pretend to know the details. These drives are getting firmware updates that disable this ability so will likely be in limited supply but many are still shipping with firmware that still allows it. You must NOT update firmware on these due to this.

I believe OP means GB not MB.
And I suspect #6 might be thinking about HB or iTunes file sizes instead of .mkv file sizes. .mkv does not compress the files, just strips out the protection. You then run them through something like HB to end up with a compressed file like the file sizes one finds in iTunes. That will also jettison other language files, upwards of several surround sound files including lossless options, etc to get the size down. So a 50GB .mkv might become a 5-15GB h.264 or h.265 file after being run through HB.

Until iTunes allows for 4K on local server I think it's still advantanges to just play discs or buy on iTunes directly. Unless you're pirating, otherwise it's just easier and better to use the commerically available content as is. And so far all the 4K discs I have bought have been very easy with the ads and stuff, and the iTunes "menu" for 4K movies is really nice. That might be part of why they don't have local content yet, because it wouldn't replicate that experience (though the real reason is most likely sap money while it's new).
I was asking about the size of the .mkv files without running it through HB. In other words, exactly what makemkv spits out assuming you rip just the main title. I have a 24TB server with plenty of space and don't need to compress my rips. Something on the order of 50GB is fine for me.

It did already before aTV 4K launch!
You just can not get them downloaded from iTunes Store. Your own rips will work fine. You may want to HB the bitrate down, though, as the aTV 4K will not play anything over 50Mbps smoothly. You'd more likely want to stay capped at 40Mbps.
I've played The Shallows without issue, using Infuse, and that offers a bitrate of 60Mbps
Excellent news, hows the raw rip size for the average 2h movie?
I'm definitely getting in on this, been ripping HD blurays for some time, and I use GPU encoding due to being exceptionally faster than CPU. Will definitely need to test GPU compression to get a reasonable storage size.
I think my USB Bluray drive won't accept UHD discs though, anyone got any recommendations for external UHD bluray drives?

That'll be a case of preserving the Rec.2020 colour space
I found this post but its using ffmpeg command line (ok, I guess this is for advanced users):
https://forum.doom9.org/showthread.php?p=1779702
The color_matrix=bt2020 bit is what I'm interested in, I'm a bit far away from testing this just yet though if anyone else is already ahead of me?
More than 50 gb.
There are only a few that can do this, including the Asus I mentioned in the first post.

Don't know about reencode, but VLC 3 beta does HDR.
Found the answer on the UHD wiki page in terms of disc size these are the largest file sizes you'll get:
50 GB with 82 Mbit/s,
66 GB with 108 Mbit/s,
100 GB with 128 Mbit/s
Not as bad as I thought, would be nice if I could find a compression setting that could drop these by at least half.

Colour space alone is not enough. As a matter of fact, it will not even turn your TV into HDR mode.
You would want all these parameters added to x265 options, but PQ-gamma, aka transfer=smpte2084 is the key. This one parameter makes TV to switch from SDR into HDR mode. All the rest are there to make picture more natural.
Oh, yes, you would want to use the 10-bit compile of the x265 encoder, to remain UHD-BD compliant.
I am using these in 10-bit-HandBrake Options box:
Code:
uhd-bd:colorprim=bt2020:transfer=smpte2084:colormatrix=bt2020nc:master-display="G(13250,34500)B(7500,3000)R(34000,16000)WP(15635,16450)L(10000000,1)":max-cll="1000,400"Full command line options (please note that smpte2084 for example has changed since the version used on linked page earlier).

Nice!
I'll have to see if that would work in ffmpeg over hevc_nvenc. As much as I'd like to do that in CPU using Handbrake - it will surely take weeks to encode! I don't exactly have a Threadripper system here.
H264 or h265? If h265 what extension? iTunes will stream 4K to AppleTV in the Computer section? Is there a new icon for 4K that can be set, like HD icon? Does handbrake correctly do Enhanced Dolby Digital 7.1....and can it interpret the newer object orientated sound streams (Atmos) that are on 4K discs?
I’m not attacking, there just isn’t good info out there yet.
Yes, H.265 encoding is very taxing on CPU, especially on my rather "ancient" early-2013 15" MBP Retina. I had a chance to run this HB10 encode on the fresh iMac Pro (base configuration, octacore, 16 threads, CPU with hardware H.265 encode support) and I saw there conversion speeds of 12-14fps (60fps UHD source @ 73Mb/s).
iTunes now takes also H.265 encoded videos in m4v files (it still only digests MP4 files for that matter). fourCC needs to be set to 'hvc1' to become QuickTime-likable.
Yes, you can stream via Computers app on aTV or AirPlay from iTunes.
No, there is no 4K icon or metadata tag for iTunes. You can recognise that on my screenshot below.
I am unable to make HB to pass through the E-AC3 track, let alone the piggybacked Atmos metadata.
I also don't see E-AC3 7.1 encoder in HB. So the best I can get is AC3 5.1 encode from higher codecs or plain passthrough if source is the same. Atmos support seems non-existent.
But I have been able to mux E-AC3 7.1+Atmos track into a m4v file using Subler. Because tvOS does not bitstream E-AC3 out into HDMI, Atmos flavor gets lost.

Hi,
My pleasure to be of help.
I bought qute some time ago the LG BP55EB40 mainly due to its slim form factor and no need for external power supply.
But it is of no use to rip any UHD disks.
So far I had no interest in getting another LG drive, because encrypted disk images are of no interest to me.
Now things seem to be changing finally. I have been playing with the idea of LG BE16NU50
I have been using makeMKV since its early days. So I would continue using that one. Seems to be in good movement and well supported.

The funny part is, that my drive has not been able to mount any UHD blurays so far, although BD-XL compatible.
