For BD:

• Carlotta France Blu-ray slightly better than Arbelos US Blu-ray, both are FiM-encodes with tradeoffs. Carlotta is best in dark scenes.

• Curzon UK Blu-ray has squished AR
  Bela Tarr Curzon Collection uses the same bad Curzon Blu-ray

BFI > Criterion

Lobster Films (Kino Lorber?) > Cohen/Eureka https://slow.pics/c/3KWXoMyR The new Kino Lorber's Seven Chances / Sherlock Jr. might be using the same restoration as Lobster Films

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

Shout! Factory 4K Blu-ray > BFI 4K Blu-ray, see caps https://slow.pics/c/nPcxCNW4

Some find BFI better but with more DNR and AI upscaling like their horrible 1979 Nosferatu 4K Blu-ray, and Shout! Factory has more over-exposed grading https://slow.pics/c/WQKmBTLJ

2000 R2 Stonevision DVD vs Shout! Factory 4K Blu-ray?

Not really noticeable difference to Germany Bildstörung Blu-ray

Germany Bildstörung Blu-ray marginally better encode than Criterion

All Blu-ray have the same old MGM transfer. Likely 2025 88 Films Blu-ray has the best encoding

4k restoration not approved for home release even for the 2025 88 Films release

251 min cut (Extended): Fox Blu-ray. Eagle Pictures has forced Italian subs in some parts

229 min cut (Theatrical): WB Blu-ray

139 min cut (US theatrical): VHS

Eagle Pictures 4K Blu-ray, caps

The 4K includes both theatrical and extended cuts. It's overall a solid upgrade over previous discs, but some will strongly dislike the color grading.
There are some issues with encoding and grain management.

Nic's review:

Some definitely messed with it as there’s grain management going on that resulted in magnetic, squishy grain movement. Both cuts (4K discs) are affected and it doesn’t look like an encoding issue to me as the bitrates don’t drop down to single digits á la Paramount or StudioCanal. During opticals, the lowest I’ve noted on the Extended 4K was around 30 MB/s vs. ~5 MB/s more for the theatrical cut.

Darker scenes are mostly (but not always) better but when it gets brighter, particularly in exteriors or scenes like the Jennifer Connelly dance scene at minute 38, I can’t unsee the digital tinkering as it does some damage texturally.

I compared it with the Eagle Pictures and Warner Bros Fox Blu-ray of the extended cut and they all look fine without grain management like that. Eagle Pictures’s Blu-ray is an older one if anyone’s curious and credited to another authoring house than 64Biz, which did the 4K.

Other than that, except for some encoding-related chroma noise that peeks through in the DV layer, Eagle Pictures did everything right. They corrected the framing to 1.85, kept the original English titles, the English restoration note, subtitles, HDR/DV is gentle and respectful of the source black levels are better than on the Warner Bros/Fox Blu-ray. Without that grain management, this would’ve been the all-timer release we all longed for.

251 min cut: Fox Blu-ray (24-bit, Eagle Pictures is 16-bit, not audible)
229 min cut: Warner Bros LaserDisc (missing 2 minutes, but original mono mix was never released on DVD/Blu-ray)

Extended edition adds scenes cut from the theatrical, but from a much lower quality source. It's intended to approximate the original cut, but to what extent that is true is debatable.
US theatrical cut is infamously bad, was panned at release and never re-released on home video.

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

France Carlotta 4K Blu-ray slightly better than Criterion 4K Blu-ray

Korea Nova Media Blu-ray probably > Criterion

France Carlotta 4K Blu-ray is FiM encoded and superior to Criterion 4K Blu-ray see caps but the Carlotta release is not English friendly

A user writes: 'the 5.0 mix does not closely resemble the matrixed stereo track included on all prior releases (save for a 2003 French DVD which had 5.1). There is significant dialogue emphasis in the 5.0 mix while the older stereo mix has ambient sounds and dialogue mixed at nearly the same loudness. Additionally, the 5.0 mix has minor limiting in select loud sequences and a strange distorted quality on occasion (one notable example is the sound of a plane taking off which plays during a static shot of clouds in the sky). The stereo mix included on the FRA UHD/BD is a downmix of the 5.0 track.'

2019 StudioCanal 4K Blu-ray (same as Optimum Blu-ray)
