Original Top Gun has only perfectly natural colors. I saw a gorgeous 70mm print last year. Also own the kickass laserdisc. The regular tealed Blu and especially the yellow/teal 3D Blu looks nothing like what Top Gun looked like originally. And this new movie looks horrible color wise.

I want to clarify this to mean what Profile like 4, 5, 6, 7, 8, or 9.

They do, it was BR2049 that he was talking about re: lifting the blacks. NOT that he makes them look grey as all get out, no no no, but he likes to sit them just above black to provide the 'framing' effect that I mentioned. He said that he did a pass in the DI on BR2049 just for the black levels so he could get them exactly where he wanted them.

You are wrongly using the present tense about a film which will be released in the future, which you have not seen.

(Gentle hint: a YouTube trailer does not count. HTH).

I can't believe Noremac is thread crapping Penton. Well I can believe it. Just sad, really sad like.

I see more and more 4K Ultra HD Blu-ray discs are being released with both HDR10+ and Dolby Vision HDR (It use to be 4K Blu-ray titles only had standard HDR10 and sometimes offering Dolby Vision HDR). For example, The Wizard of Oz on 4K Ultra HD Blu-ray that I purchased back on October 29th 2019 has both HDR10+ and Dolby Vision HDR. However, since no USA display exists in 2019 that has both HDR10+ and Dolby Vision HDR I am not able to compare the two HDR formats. There are international Panasonic displays sold outside the USA that supports both HDR10+ and Dolby Vision HDR. Since HDR10+ is backwards compatible with older HDR10 equipment, consumers will be able to play the HDR10 core if they do not have HDR10+ or Dolby Vision HDR technology on their display and 4K Blu-ray player.

Dolby Vision HDR is much better quality when compared to HDR10+, since HDR10+ only supports 10 bit 1.07 billion colors with peak brightness up to 4000cd/m2. Where as Dolby Vision HDR supports 12 bit 68.7 billion colors with peak brightness support up to 10,000cd/m2. In the years to come in theory high-end displays might be invented that support the full specs of Dolby Vision HDR at 12 bit 68.7 billion colors with peak brightness up to 10,000cd/m2. Then we will not need tone mapping anymore. The reason why we have tone mapping in 4K displays and some 4K Blu-ray players is because of limitations in the display being able to display the peak brightness that is offered by the HDR formats. There are big improvements that need to be made in display technologies so that tone mapping can be bypassed and not needed anymore.

That is terrible; I'm not very proud to be Canadian when something like that happens.
Some people are better to stay home to watch movies.

And very few BR titles have HFR (two from this film director) ... Ang Lee.

https://www.youtube.com/watch?v=H0jv...ature=youtu.be

We aren't used (our eyes with movies) to this, so it takes time to adapt.
The Olympic Games, Super Bowl, Racing cars, soccer games, ping pong, tennis, gaming, anything that moves fast (Top Gun jets) should look better with HFR.

We are behind when it comes to culture, technology, civilization, intelligence level put in practice @ the service of the planet (humanity, wildlife, healthy climate and entertainment). IMO

Happy New Year!

Yes, I want those improvements, and yet the TV manufacturers have gone off in completely the opposite direction, and are pushing higher resolutions like 8K, instead! I want fully 12 bit panels, improved near-black rendering, perfect mura uniformity, better anti-reflective coatings, longer lifespans, zero vignetting, etc. A higher resolution is at the absolute BOTTOM of my wish-list of things I want next

HDR10 can and does go up to 10k nits. It's a myth that only Dobly can do it. Just FYI.

To the outside –



it’s been my pleasure to keep you, Scottishguy, mrtickleuk, and others at the cutting edge with behind the scenes of Top Gun: Maverick as it was happening (without spoiling the plot) and also provide tidbits on next gen video be it nuances regarding HDR, WCG or HFR

thank you for the privilege of your time
have a Happy New Year

[LordoftheRings]

The pleasure was all mine...Happy New Year to all your family and friends.

Ah, there's the problem.

Watching Blu-rays and everything on a crappy old CRT.

Plus, as some longtime readers may recall, even the best CRT of the time had inherent deficiencies with regards to mastering and home viewing of the deliverable - https://forum.blu-ray.com/showthread...t#post11158854

I only wish that the Top Gun/Top Gun: Maverick super fans out there on social media sites like twitter, YouTube, Instagram, etc. don’t primarily use the sequel as a platform to leverage their personal sales of merchandise like T-shirts and such but also really put their money where their reputed interest lies by bringing awareness to and purchasing either the Blu-ray or UHD Blu-ray of Top Gun: Maverick for repeat viewing/listening as disc ownership is permanent and tangible as opposed to experiencing the theatrical run, good as that may be to watch it on the BIG screen (be it Dolby Cinema or IMAX) for one’s initial exposure to the motion picture as a premier event.

According to that article and others they claim 4k nits instead of 10k nits for HDR10+. If HDR10+ specs can do 10k nits then all that is missing is the 12 bit color depth.

[JustinZed]

HDR10, HDR10+, and Dolby Vision all use the same PQ EOTF, which is defined from 0 to 10,000 nits.

They're wrong. There are literally HDR10 discs out there that go up to 10k nits.
