Not very bright except for the title and considering it was done under Malick's supervision, it's probably the way he wants it. But man this is one beautiful restoration. Absolutely breathtaking. It's a must own in my book.

I've got Do The Right Thing so that one is doable in the near future.

Pretty conservative grade with mostly reserved averages but still has some bright highlights at around 2-300 nits. Very good contrast with retained shadow details and deep blacks. Looks similar to The Seventh Seal. Once scene in particular has severe compression artifacts (visible in the sky in cap #5) and some scenes have optical printing which naturally looks soft. Otherwise it looks excellent with very fine grain.

Looking at these can be interesting, I hope someone here can get to the evil dead trilogy, first three child's play films, or first three halloween films.

Macatoullie have done at least Evil Dead 2 and Army of Darkness. Not sure about the first Evil Dead.

When I get the Ocean's trilogy from Target (my order hasn't shipped yet), I plan on running all 3 through their paces. Gotta shake off the rust and remember my old processes first, though.

Don't have the first one, unfortunately.

I've got it somewhere, tho it's the Scandinavian release so no Dolby Vision.

I remember a small amount of discs that made me squint from brightness, it's usually all when it's a dark scene and sudden brightness, first one I remember affecting everyone in the living room was Encanto when the candle goes bright during a flashback. E.t. had a bunch of bright sources and oddly enough, the book of life on blu ray, whenever the candle person appeared fully in frame, my eyes couldn't handle how bright he was, wonder how that movie would've been on 4k blu ray. The hdr version on disney+ looks quite nice.

Vast majority of this stays under the 1k nit window but it hits toward that peak pretty often. A fairly aggressive grade, all things considered.

My strongest captured highlight (1083 nits) and frame (108 nits):



WCG gets used pretty regularly in the background of a lot of shots I captured but stands out in two settings, a bar in Philly and during Conlan's entrance:

Decided to update my Past Posts link to include every analysis done in this thread, organized by movie title alphabetically with the author included in parenthesis.

So if you ever want to check for a title, just use that link. If I missed anything, let me know.

Phantom Thread (Universal Studios)

HDR10
Mastering display luminance: 1000 nits white level, 0.005 nits black level
MaxCLL: 637 nits
MaxFALL: 75 nits

This is a rare bird. Seems like they're using a mild low pass filter. Blacks have a tendency of looking lifted, which almost makes me think like they're trying to emulate the look of a theatrical print. Peaks are not super high most of the time but it does indeed reach bright territories (the photo shoot is pretty obvious despite peaking at around 360 nits).

A really, really nice and stable presentation in my humble opinion even if the grain looks a bit chunky (even for 200 and 500T). Too bad it seems to be OOP or at least unavailable at most retailers.

The link for Gran Torino takes you to Gran Turismo.

Deep Red (Arrow Video)

Mastering display luminance: 1000 nits white level, 0.0001 nits black level

Pretty consistent averages and good highlights. The strong peaks at around 8-900 nits seem to indicate a proper conversion from Cineon LOG to ST.2084 as they're limited to just a few pixels (an SDR to HDR conversion would normally make them much lower or the entire image brighter). Colors look fantastic too.

Strongest highlight (937 nits), frame (119):



Didn't find a ton of WCG usage in my shots, just detail work:



Despite that, I think it's a great looking disc: subdued in darker shots but with strong highlights that most sets can wrangle. An easy upgrade for one of the best action movies of the '90s.

Fixed, and added your latest to the list.

I think it's currently between pressings. I ordered mine back in Feb. when it was temporarily out of stock and it eventually arrived like 3 weeks ago.

They pushed everything by a stop so that might explain the chunkier grain, in fact that was the entire point of doing so as PTA wanted grain but modern stocks read so cleanly that he had to 'dirty' it up a bit. I have to wonder if they did the video transfer from timed IP (a la Nolan) which would also account for the low pass filter-type effect perhaps? And yes, the thin blacks are entirely by design, often using a low-con filter when shooting.
