FiM encode and a very good new master

The 4K discs in both Criterion and Imprint sets are FiM encodes, but low-passed. The compression is better, but some of the grain is lost. Difference is pronounced in screen caps, but not likely to be noticed during playback, without a reference to compare it to. Comparisons

All discs use the same source transfer. It's not of the highest quality, and it includes some slight distortion, looping, clicks, pops, and hum. Criterion cleaned it up for their release, but unfortunately also lost a lot of fidelity in the process.

MGM NTSC DVD doesn't seem to have some of the more prominent distortion and has slightly different EQ but is otherwise the same.

The Criterion Complete Kubrick and Imprint 1953-1957 sets include remastered BDs. All standalone releases are from an earlier master.
Arrow UK Blu-ray has an exclusive isolated score & effects track. Kino Lorber and Imprint have an exclusive commentary each.

Indicator Universal Noir #1 Blu-ray shares the same transfer with Kino Lorber, but has better encoding 

4K restoration from Original Camera Negative

MoC better encode than 2016 Olive Films Signature

Kino Lorber has new 4k resto, not sure about color grading

Included in the Complete Kubrick box set with FiM encode of the same master from the Sony release without the filtering; Comparison between Sony and Criterion.

(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 The 2008 Blu-ray of the 2007 Coppola Restoration while an imperfect outdated disc is LIGHT YEARS better than this 4K desecration.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.

The original 1977 censored cut has never been officially released on home video. The 1981 cut and the 1990 EU cut are available on VHS. The 1992 Trilogy cut was released on LaserDisc and VHS. The 2012 and 2016 HD versions were broadcast on AMC and streaming HBO respectively but neither are available on either platform anymore currently. The Chinese 1080p blu-ray on the high seas is probably the most accessible and affordable way to watch it, (albeit with terrible compression) and appears to be a Webrip of the 2012 AMC HD tv broadcast. It’s on two BD-25 discs with lossy Dolby Digital 5.1 audio and with subtitles for Sicilian dialogue.

Germany Plaion/Plaion Blu-ray is the new 4K restoration
