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.

MoC 4K Blu-ray and Kino Lorber 4K Blu-ray are similar

US Criterion 4K Blu-ray > International WB 4K Blu-ray see caps. While WB has better highlights, Criterion resolves grains better and is believed to have a more accurate color grading.

For Criterion 4K Blu-ray: The better resolution and the subtly adjusted grading paired with HDR makes for a more rounded, fine-tuned experience. The encoding is a leap forward from the Blu-ray as darker shots are no longer a macroblocking mess on the 4K.

Criterion 4K Blu-ray https://slow.pics/c/086ANjCg

The UHD is slightly cropped in.

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

Mosfilm official 4K Youtube Streaming is the only release for the new 4K restoration. Mosfilm's release has no sepia, and whether or not if this is the original color grading is still under debate.

For other releases: Netherlands Lumière Blu-ray is best, but all releases of the 2K restoration have issues:

• German Filmjuwelen 4K Blu-ray is 2K upscale and has incorrectly pitched Russian audio. See caps

• Criterion Blu-ray/Germany Filmjuwelen Blu-ray have yellow tint on sepia scenes

• France Potemkine (Standalone) has raised blacks and poor encoding

• France Potemkine (Boxset) has orange tint on sepia scenes and poor encoding

• Netherlands Lumière has correct sepia scenes, good encode, but gamma is slightly off.

• Italy General Video Recording has correct sepia scenes but gamma is off (more so than Netherlands Blu-ray and worse encode)

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

Germany Universum is the newer 80th Anniversary resto https://www.hometheaterforum.com/community/threads/m-1931-fritz-lang-80th-anniversary-restoration.300983/

StudioCanal 4K Blu-ray/Lionsgate Limited 4K Blu-ray (shared encode); slight improvement over the 2015 StudioCanal Blu-ray

StudioCanal/LG UHDs port the 1999 Criterion DVD, considered the best source

StudioCanal has a remastered Blu-ray, Lionsgate only a 4K Blu-ray

France Carlotta Blu-ray has best encoding of France/Hong Kong/Japan. Criterion/BFI are older master

(Raro/Madman/Shochiku DVDs probably similar)

Arrow 4K Blu-ray > Kino Lorber > Capelight Germany

(transfer of the 1989 MGM LaserDisc, without problems plaguing Kino Lorber's release)

Arrow UHD is an update of the original 4K scan done for their BD. It is also visually far superior to the Kino version and adds Dolby Vision HDR. The Arrow UHD uses a new LD mono capture and has none of the issues or processing found in the Kino UHD which also used an LD mono capture and somehow mucked it up. Short of a brand new scan, the Arrow UHD is as good as it possibly can be.

An undeniably significant improvement from the BD yet still severely flawed. See DFIC's review.

See chris's review

But Warner Bros 4K Blu-ray is very similar.

2021 StudioCanal France Blu-ray has best encoding of the three (France/UK/Italy) that use the 4K restoration
