Output can be tonemapped to SDR or in an HDR container or both.

Also work with many many inputs (like 20+)

Does it only work with backup files, or does it do screenshots with discs 'on-the-fly'?

Only MKV rips are officially supported. It could work with the original M2TS files, but some frames might go out of sync because FFMS2(frame indexer) is not perfectly frame-accurate with that container. VC-1 isn't frame-perfect either, but HEVC/H.264 mkv should always be frame-accurate as long as you enter the correct frame delay.

At least caps 12 and 21 definitely look "scrubbed"....
Always loved the grain/ noise in cap 21 on bluray. Can't check, if I can live with the changes and make the 4k my goto, yet, as I'm still waiting for my disc to arrive....

(The caps here are of BL only. From other caps here, it seems like Paramount's disc relies on FEL to expand brightness.)

HDR screenshots, in order to view them correctly on Windows, you must use a Chromium browser with Windows HDR enabled, and the brightness slider set to the value of 31.

Criterion now has the best version for the western market and seems to match reference promo shots exactly, while CG ITA did an excellent job with a more colourful HDR grade, which some people will prefer. Here are some comparisons for anyone curious. When comparing in motion on an LG C2 OLED, I found the CG ITA HDR grade had more contrast between lights and shadows, and substantially more colour which made me think "Pixar look" or video game, while the Criterion USA SDR grade had more refined grain and detail, but with a slightly more subdued, contemplative colour palette, which seems to be the original intention. Both have their merit.

Note: HDR set is intended to be viewed on HDR displays in HDR mode, and SDR Tonemapped set is for SDR displays, both provide different perspectives.

I have a hard time believing those that created Flow intended the sky to be flattened like it is in the Criterion screen cap:

Not that I expect the Criterion Echo Chamber to ever admit something is off there if its an accurate capture. lol

[fkid]

Don't forget, that is exaggerated when you compare in HDR PQ, here is the same shot tonemapped to SDR. You can have your opinion, but the creator behind the movie recorded a commentary track for that specific release and there are promotional shots that came out before this movie was ever confirmed for physical distribution, that match the Criterion release. Like I said, CG ITA definitely made their HDR grade more colourful and did a nice job, but it's not a high probability that is the "intended" look, given the promo shots and the fact the delivery could have easily been in HDR/DV for Criterion's disc, and it wasn't. Cheers.

Creepshow 2 (1987) Arrow 4K vs BD comparisons
https://slow.pics/c/rhFDWC4g

Framing is finally fixed (why couldn't they do this on The Stuff??). Engine House encode. Seems to be a huge upgrade

[fkid]

Imprint AUS seems to show marginal improvement in terms of encoding vs. Icon GBR, but both are excellent and include the same, proper CMV4.0 Dolby Vision w/MEL. Criterion would be wise to learn from these smaller boutique labels, or maybe just hire their staff, lol.

The comparison below is meant to be viewed in HDR mode on an HDR display.

Don't you mean they include Dolby Vision cmv2.9 metadata that's actually a downconversion of cmv4.0 from the original master? That's the best case scenario (one knows this if the Dolby Vision Level 1 floor is 10 nits instead of 2.5 nits), because so far no there's been no Dolby Vision cmv4.0 on disc.

There are plenty of CMV4.0 discs. The latest Kino discs are all CMV4.0:

Night of the Juggler 1980
Coneheads
Happy Gilmore
Billy madison

Only the ugoos am6b+(with CE) can play them correctly with FEL though. The bluray players fallback to the cmv2.9 block

This is news to me. I guess that the reason why the vast majority of UHDs aren't cmv4.0 is because no blu-ray players will play it. Still, it would be nice if this had become standard practice in UHDs for years now, to take advantage of those who have devices that support cmv4.0. But hey, we still see studios cutting corners by having discs be HDR10-only, so even having Dolby Vision on disc is to be thankful for.
