Mulholland Drive (The Criterion Collection)

HDR10 and Dolby Vision FEL
Mastering display luminance: 1000 nits white level, 0.0001 nits black level
MaxCLL: 1000 nits
MaxFALL: 144 nits

So first off, I messed up the album. The tonemaps I uploaded are in 1920x1080 pixels. They're still present in the links below but for those who want full 4K tonemaps I've got them here. I used ACES this time so they're not completely identical in highlights.

Very nice, conservative presentation. Averages are similar to that of SDR but the peaks go a bit higher whenever needed. Some think it looks too dim but imho it just adds to the dreamlike atmosphere.

Already off to a bad start since it was a remaster and not a restoration.

Curious if yall are able to do upscales that are a bit unimpressive like shaun of the dead, shrek, the first two star wars prequels, and pan's labyrinth to see if they utilize hdr much

Translated from French so I always cut him slack for a single word, and watch the videos in full. His earlier videos are dubbed by him, but the later ones use an AI voice as he said he's not confident with his English. For his diligence and detail it's worth watching.

Shaun has a bunch of highlight detail that's not there on the Blu. Mightn't seem impressive in terms of numbers and plots and graphs in purely technical terms but compared like for like it's a decent little upgrade IMO: https://forum.blu-ray.com/showpost.p...&postcount=691

What a stunner. Huge highlights, tons of detail (from a seemingly new scan), healthy bitrate and lots of WCG usage. Only real downside is the lack of a Dolby Vision layer to help tonemap those peaks.

Strongest highlight (4.4k nits) and frame (194) captured:



Plot shows 5k and 345 nits, respectively. As mentioned before, there is a ton of WCG usage here, in many directions.

Luminance values and WCG usage aren't quite as strong here but it's still a lovely disc. MaxCLL is 4k nits, FALL 188. I captured 1.3k nits and 401, respectively:

Reminder that anyone can contribute to the thread through the Colab.

Cleaned up the bloated code. Now uses just 2 dependencies, so should be quite stable. Also added the option to upload through a folder from google drive, speeding up the process.

Output is almost identical.

Definitely seems faster now. Saved it off and tweaked it slightly to run locally. Thanks very much.

Very similar peaks and averages to Eleven here, with 4.8k nits and 342 nits, respectively. I captured a peak of 4.1k and frame of 180:



WCG usage is predictably strong:




One thing I found odd, though: a noticeable drop in detail compared to Eleven and Twelve. Saw some chatter that maybe Warner finished new scans of those two and it doesn't surprise me, looking at the screenshots (usual caveats apply here, since we're looking at tone-mapped images). Obviously this could be an intentional look by Soderbergh (I don't know the technical details of how they shot it).

Some examples:

[nissling]

Trainspotting (The Criterion Collection)

HDR10 and Dolby Vision FEL
Mastering Display Luminance: 1000 nits white level, 0.0001 nits black level
No static metadata for MaxCLL nor MaxFALL

Luminance is overall very, very reserved. Apart from the London montage (which is really bright), the brighter peaks are usually limited to the party scenes. Other than that it mostly stays at around 100 ntis or below. Roll-off is kind of uneven as it's sometimes quite smooth and other times just barely avoids clipping. Colors look absolutely magnificent with superb color timing and absolutely no clamping whatsoever. Some of the very best I've seen in a 90s film.

Whether it's revision or not (have only seen the film on Laserdisc in the past so I cannot comment), I think Trainspotting has aged like fine wine and am extremely satisfied with how it looks here. My only complain is that there are visible compression artifacts in the London montage, most notably in the skies.

Something got messed up with Imgbb while I uploaded the images and I couldn't make an album unfortunately, but at least they're in the spoilers below...

I'm currently working on A Hard Day's Night, Suspiria, Stand By Me and... Terminator 2.

T2 may take some extra time. The more I look at it, the more I realize how much is wrong with it and to which extent. It's so absurd that I may have to compare it to some of the restorations I've worked on myself and see just how much you have to mess up to even get near the same level as T2.

The War of the Worlds (1953)
Paramount - USA
HDR Formats: HDR10 and Dolby Vision FEL

Measured Max Peak Brightness: 2,287 nits
Measured Max Frame Average: 1,292 nits
Max Peak Brightness in DV Metadata: 1,266 nits
Max Frame Average in DV Metadata: 108 nits

Strong use of HDR and the P3 color space throughout the film. Heat rays really pop, especially when aimed right at the camera. There's an oddity here in that the DV metadata numbers are significantly lower than the actual encoded brightness for much of the movie.

Three-strip Technicolor is so good both in terms of color volume and highlight coverage. The practical speed of the film stocks got heavily reduced due to the prism. In the 30s they were limited to around 5-10 ASA, which is crazy low and required plenty of exposure. Despite all the trouble those filmmakers went through (as well as the restoration artists), the fact that Technicolor is still so iconic and remembered for its quality features says a lot about how good it is.

Hopefully we can someday get The Adventures of Robin Hood on UHD. The fires in that film look really good even on the old Blu-Ray.

Dark Water (2002)
Arrow - USA
Honogurai Mizu no Soko Kara
HDR Formats: HDR10 and Dolby Vision MEL

Measured Max Peak Brightness: 213 nits
Measured Max Frame Average: 183 nits
Max Peak Brightness in DV Metadata: 253 nits
Max Frame Average in DV Metadata: 26 nits

A nice filmic transfer, but definitely not 4K HDR eye candy. The movie is soft and dim and dull by design, matching the mood of the piece; this holds true even with bright objects in nighttime or the rare daylight shots.

Like The Bad Guys, this seems to essentially be a Rec. 709 grade in a wider-gamut container; the most saturated colors closely follow the edges of the smaller color space, with only incidental spillover into P3 (some of which may be "rounding errors" from using 8-bit caps). Rounding errors also presumably account for the measurement on the title card's heatmap exceeding the maximum measured brightness of the film.

Dolby Vision is technically present but pretty pointless given the very low brightness of the film, the fact it's a Minimum Enhancement Layer that won't shore up the compression, and the fact the dynamic metadata barely ever shifts at all.

This is awesome. Is there something similar for the WCG visualization?
