4K Blu-ray

Fine new master, grade and encode caps

Arrow 4K Blu-ray marginally better than Kino Lorber 4K Blu-ray

Caps by cinemaniac, look great but

Vinegar Syndrome 4K Blu-ray boosted the audio and introduced clipping. Old Paramount Blu-ray maybe better?

Arrow includes the original theatrical sound mix in all its glory. All previous releases other than the 1996 AC-3 LaserDisc were tamed relative to the original theatrical DTS track.

The disc is authored by Duplitech, but doesn't exhibit any compression issues, though the image is pretty soft, that's likely just down to the stock used.

Old New Line Video LaserDiscs include an exclusive commentary track.

Shout! Factory 4K Blu-ray caps, very impressive upgrade, VFX shots look a bit better as well thanks to the new scan and HDR, magenta touch in the old master is no longer there

Both 88 Films and Germany Capelight are superior to the Shout! Factory in HDR10 but their FEL layer may even things out. Objectively, the Capelight looks best as they avoided the chroma blocking that’s visible in 88’s disc but they in turn included an Atmos mix. I have the Shout! Factory, love how it looks and the 4K transfer is spectacular. https://slow.pics/c/vPmFQSAH

Shout! Factory has the exclusive The Beauty of the Baud and the You Can't Stop Us All featurettes.

• 4K caveat: A variety of VFX set pieces and touch-ups were added in scenes throughout the film, probably for continuity or consistency, although they might be unnecessary or revisionist. Clouds are added to clear sky of the last act.

• AI is used to fix an unwanted camera movement in one scene.

• some shots had been further stabilized, resulting in strange motion blur.

Also has missing dialog intact.
But it can be argued that the Warner Bros 4K Blu-ray 5.1 (remix) is technically a better mix.

The subtitles on the initial release has some issues.

The 5.1 track on the initial release has an error. This is corrected on the later "v2" discs.

Criterion 4K Blu-ray (review)

> Vinegar Syndrome 4K Blu-ray

Criterion 4K Blu-ray for 5.1 remix. Original stereo mix on UK Second Sight DVD.

Arrow caveat: the 4k drops some extras like the TV Cut

All 4K releases are sourced from the same mediocre transfer provided by Bandai, with various amounts of tweaks. Japanese disc presents it with the least tinkering.

The best attempt at improving it comes from the German/French releases from KSM/All the Anime, both of which use the same master with HDR regrading (original grade is SDR in HDR container), tasteful regraining and sharpening, in an attempt to breathe some life into the middling transfer, making for an arguably more pleasing viewing experience.

All earlier releases are from an even worse transfer, with significant black crush, with the exception of a Japanese TV airing, which doesn't suffer from that issue, but instead is heavily sharpened and suffers from poor encoding.

Original matrixed stereo mix: Bandai JP 4K Blu-ray
Most discs include this track with comparable fidelity (which is excellent).

Dolby Atmos remix: Lionsgate US 4K / All the Anime FR 4K
6.1 remix (from Ghost in the Shell 2.0): KSM DE 4K / All the Anime FR 4K

All tracks on the Lionsgate US 4K replace the original ending song with the one heard on the English dub. As the Atmos track on the FR 4K is just a port, it also has this song replaced.

Japanese 4K includes English dub and subtitles.
French/German 4Ks are not English friendly, with no dub or subtitles.
French disc includes the Atmos track, but the German disc does not.
