WB Europe 4K Blu-ray slightly better encoding than Criterion (caveat: missing Criterion extras)

(Britain release only has 5.1)

The Paramount 4K "restoration" is a desecration. It has completely revisionist color timing, harsh HDR, treatment of stock footage, bad encoding, selective DNR and grain management so bad that the entire screen frequently freezes up with only characters moving around in grain soup. It is so bad that the film's restorer Robert Harris publicly washed his hands of it saying essentially the 2007 restoration (with Willis and Coppola supervising) is how the film was intended and made. This is Paramount's modern version done their way. The new 1080p SDR Blu-rays in print are the crap 4K desecration master with the same problems still there just harder to spot and with crap encodes.
The mono option is an unnecessarily processed version of the lossy mono from the 2008 Blu-ray. The 2008 Blu-ray of the 2007 Coppola Restoration while an imperfect outdated disc is LIGHT YEARS better than this 4K desecration. The only truly major issue is that it is very slightly redder than the 2007 finished master as seen on DCPs. The lossy mono on the 2008 Blu-ray is the best version of the original mix known to exist as it is better than the late 80's mastering for VHS and LaserDisc.

Imprint Australia 4K Blu-ray has slightly better compression than Criterion 4K Blu-ray.

The master in DV looks all but identical to the Criterion’s HDR grade. Detail-wise, FiM’s encode looks like it uncovered a tiny bit of extra high-frequency information that got filtered on the Criterion. See nicolas review

1990 Criterion LaserDisc/1993 MGM LaserDisc/2002 R2 MGM DVD are the best. See blah-ray https://blah-ray.blogspot.com/2018/01/raging-bull-1980.html

Imprint Australia 4K Blu-ray has better audio than Criterion 4K Blu-ray, from nicolas:

I believe that what’s on Imprint’s 4K is one of the good mixes MGM and Criterion released during the LaserDisc days. Music is powerful and detailed, dialogues have excellent fidelity and ambient sounds have perceptible depth. I compared the "new" 2.0 with the anemic 5.1 as well as the Criterion 4K mix and could clearly hear the improvements.

The 5.1 on Sony 4K Blu-ray is from the 1989 70mm mix. The original is 4-track. not on the disc.

(caveat: "there's" in first "there's no place like home" utterance in final Kansas scene truncated)

4k restoration. Superior to Germany Kinowelt or Japan Kadokawa, see caps-a-holic

Crystal clear, albeit with some distortion in louder areas

The 4K Blu-ray reuses the same poor mastering used on the 2006 WB Blu-ray, only with a completely unnecessary bass cut and extra noise reduction.

Even putting resolution aside, the Warner Archive 4K Blu-ray has the best video. The old Blu-ray master and earlier DVD both had massive issues with colour.

That said, picture on the 4K Blu-ray isn't perfect, with strange posterized magenta glints and some instances of DNR: https://bsky.app/profile/dagscott.bsky.social/post/3leahavqi7k2l

Included in the Complete Kubrick box set with FiM encode of the same master from the WB release without the filtering; WB 4K early pressing has errors of a shot, later pressings fixed. Comparison between Criterion and WB.

Paramount 4K Blu-ray. See caps
HDR/grading: nice, but some blown out
Encoding: inconsistent, smeared motion
DNR: inconsistent, frozen
Old Paramount Blu-ray is arguably a solid alternative choice

Paramount 4K Blu-ray mono is different version of the Blu-ray mono from the same old 2000 DVD transfer.

The 5.1 remix on the 4K Blu-ray is an appalling remix done by going wild with artificially generated stems from Park Road Post who were given the surviving mono to separate. The experience is jarring and fidelity to original mix in terms of level balance, directionality and impact is nonexistent. Not only does this sound painfully weird, but the Paramount mixers then did whatever they wanted in terms of LFE, sound pans and effect changes.
The original mono mix was not restored and still needs it badly. The 4K master is filled with frozen grain examples coming and going plus some HDR issues in addition to the usual Paramount problems. It is simultaneously better and worse than the Blu-ray master.

StudioCanal 4K caps.Criterion Blu-ray better encode than StudioCanal Blu-ray.

Probably. No comparison with French Factoris Films 4K Blu-ray, but former has Dolby Vision and higher bitrate.

For standard Blu-ray, the MoC/Cohen are a 4k transfer https://forum.blu-ray.com/showthread.php?t=112722&page=5
