4K Blu-ray

Preferences will vary, the restored track sounds good, but not necessarily faithful to the original elements.

(Jokers 4K Blu-ray has forced France subs)

The Jokers 4K Blu-ray has raised black levels/gamma issue, good when fixed

Universal Dracula Complete Legacy boxset 4K Blu-ray or Kino Lorber 4K Blu-ray no comparison available

FiM encode and none of the low-pass filtering present on the Criterion 4K, resulting in more detail and better handling of highlights on Imprint
Review, comparisons

All HD and 4K sources use the same 2009 restoration. Criterion's master (also used by Imprint) is a bit more rolled off, though the difference is minor.

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

Criterion 4K Blu-ray, caps

As with other Kurosawa 4K's, Criterion has a less processed master than Toho and BFI.

Criterion NTSC DVD overall. The 4K restoration's track is denoised and sounds muffled, but has a few of moments where it edges out in detail

Audio analysis between the Criterion 4K Blu-ray, BFI Blu-ray and Toho 4K Blu-ray

The mono on the Criterion is severely filtered resulting in it sounding incredibly muffled. It is nearly as filtered as the 2003 original Universal DVD which had extreme filtering and sounds horribly thin. The 2008 DVD remaster and original Laserdisc analog mastering are mostly left alone. The original LD master is from a worn element but otherwise sounds very natural. The 2008 DVD is the highest quality version we have without the heavy filtering and the defects of the LD master. It isn't perfect but easily the best of the main four sources by a dramatic margin. 

The existing 4K SDR restoration looks excellent, but the Criterion extras are limited and disappointing. The classic Stewart interview commentary from the LD is ported over but given a new mastering. Compared to past releases it has been very slightly noise reduced.

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.

Imprint AU 4K is world UHD debut and encoded by FiM. Part of the The Cinema Of Powell & Pressburger - Collection Two set.

New restoration looks stunning: caps

> StudioCanal 4K Blu-ray. Older DVD or LaserDisc probably even better

All blu-ray releases so far is from the 2010 scan.
