4K Blu-ray

Vinegar Syndrome 4K Blu-ray see caps

For Blu-ray, UK Second Sight is better than Kino Lorber Blu-ray

> Carlotta, with debatable color gradings from master.

"Carlotta’s encodes were terrible with heavy blocking in the highlights and pervasive chroma noise. Criterion / NexSpec did much better and only occasionally struggles with skies. Grain is finely detailed and it doesn’t look filtered. Grading is debatable and particularly whether all three subsequent films (shot years apart by two cinematographers, one of them being the legendary Néstor Almendros) have roughly the same visual identity. Still, colors are adequately balanced with variations in the (yellowish) hues, there are no tints, black levels and shadow detail is excellent."

(still not great)

Criterion 4K Blu-ray is similar but has a short scene where the hum from machinery at the oil rig has been attentuated. It's a decent improvement over the previous disc which had considerable bass reduction.

(caveat: it's missing a minute of footage, plus usual PAL speed-up)

All Blu-ray tracks originate from the same transfer, but with strong noise gating and terrible EQ, adding a compensatory bass and treble boost, sounding boomy and accentuating the hiss despite less detail.

StudioCanal 4K Blu-ray marginally better

Color is fine

With better detail and grading than the China 4K Blu-ray. Comparisons

But all are within the margin of error, minus Criterion

> MoC > Olive Films. From nicolas:

The master is good but it’s not that big an upgrade from the Olive Films disc and Vinegar Syndrome’ encode has some blocky highlights. A shame that they didn’t hire David Mackenzie here.

Cinématographe has unnecessary noise gating not present on the previous releases.
