IMAX Enhanced

[sapiendut]

DV and HDR10+ works differently. HDR10+ works really well on lower-end HDR screens whereas DV requires more capable HDR handling of the screen. At least that’s my understanding.

I’m still backing IE in hope to get native IMAX features with the best PQ/AQ possible.

In that case, HDR10+ won't really do much for you. Vincent Tech says that HDR10+ is optimized for 500 nit TVs. He did a HDR10 vs HDR10+ comparison, on the exact TV you're getting, I believe, and he did not see any difference.

You won't really see any benefit from HDR10+ unless you've got some cheap 500 nit edge lit display, which isn't the case for you.

I'm looking into getting that TV as well.

I turned on and off HDR10+ and checked the difference on my current 65FZ1000, I can’t tell the difference either. I’m buying the GZ for DV functionality (currently I use my 55X900F LCD or my parents’ E9 to check/review DV movies)

I'm not so sure that they do. I don't know if those comments, not just you from you but also people like Vincent Teoh, are coming from an actual tech evaluation of the mapping itself (like, how it actually works) or just from viewing the content itself, but DV should be just as effective on any DV enabled screen, seeing as the primary trim version is usually an SDR 709 100-nit pass. Or perhaps we've got the wrong end of the stick and Vincent wasn't implying that DV was any less effective, he's just saying what HDR10+ is seemingly best suited for.

It's worth bearing in mind that HDR10+ is being primarily used by Fox who master their HDR content to 1000 nits for disc, right, so if you have a display that can handle such encodes "1:1" (as Kris Deering said of the ZD9) or near enough then you literally have no need for dynamic mapping, other than to smooth out any bumps in the backlight dimming which wouldn't apply to OLED anyway.

But if studios who encode 4k-nit base layers were to use HDR10+ then we would potentially see more of a benefit to it on higher-spec displays, but as Warners are yet to grace us with 10+ on disc and Sony are happy to just keep plowing ahead with HDR10 then it might be a while.

Vincent definitely never implied that DV was less effective. On the contrary, in one of his videos he said that he saw a much bigger difference between DV and HDR10 than he saw between HDR10+ and HDR10, meaning that DV is the more effective dynamic HDR format. But I guess we'll have to wait for a direct HDR10+ vs DV comparison on the GZ1000 for more accurate results.

All he said was that HDR10+ was optimized for 500 nit (and lower) displays, and that the benefit of that specific format will be noticeable on such displays, but not so much on ones that have a peak brightness of over 500 nits.

[Geoff D]

As I said, I'm not sure if that's coming from any official insider-led technical standpoint or if that's simply his opinion, but that 10+ has been restricted to mostly 1000-nit mastered discs means that it's just not going to make a huge impact unless your TV is absolutely appalling at tone mapping. More and more sets have their own brand of 'active' tone mapping these days which is what also cuts into 10+'s key USP, one could say the same of Dobly as well but at least that has the potential for a full 12-bit rebuild and also retention of >1000 nit detail in the enhancement layer if the base layer is mastered to 1000 nits.

If I'm not mistaken, Samsung themselves have emphasized the benefit of HDR10+ to lower end TVs specifically.

HDR10+ is basically worthless for most of the regular posters on the 4K forums, as most seem to have mid to upper end displays.

[Geoff D]

Seeing as that's what most of their core TV business consists of, I'm not surprised they came up with this wheeze to get them to look betterer.

All the dynamic stuff is always for lower spec TVs

That's not true. Geoff has posted about differences between HDR10 and DV on his ZD9. So has Vincent Teoh. Perhaps not mindblowing differences, but they still exist. With HDR10+, there appears to be no benefit at all to higher end TVs.

DV has features other than dynamic metadata that make it a more useful format.

Put your foot into it that time. DV is not like HDR10+.

[eddievanhalen]

I have a Panasonic 420 which is HDR10+ enabled and a Samsung set that was recently updated to HDR10+. Watching Alien, my only HDR10+ disc, I prefer how Panasonic's HDR Optimizer looks rather than HDR10+, all this on a 600/700 nit 49" set.

current Imax Enhanced titles on Sonys streaming thing:

Venom, Jumanji Welcome to the Jungle, Ghostbusters Answer the Call, Life, Inferno, The Walk, Spider Man Homecoming, Alpha, Only the Brave, resident Evil The Final Chapter, Chappie and Pixels


im curious if ANY of these movies even use an expanded ratio, since its confirmed that Venom is widescreen the entire Imax Enhance "experience".

Here’s the tragedy: IE is supposed to be a seal of quality certification, yet the content is streaming only.

Right there... that's the crux of the issue with IE. It's just a bunch of B.S. in order to snag licensing fees. It's what THX became.

Where did you see these available? I logged onto the Privilege4K app and saw only the four IMAX snippets.

If you have a LG 2018/2019 or Panny 2019 OLED, the DV should definitely look better than the DV on Sony. Panny have followed LG's footsteps on DV.

IMAX enhanced aka THX-2 plus grain reduction sounds like marriage made in heaven.

[sapiendut]

I’ll be getting the Pana GZ2000 as soon as it becomes available. I saw what it can do during CES2019 and my reaction was “dammit, my (then) 1 month old FZ1000 is now junk”

THX did nothing to process the picture or sound.

Grain reduction is almost always taken too far. You end up with wax figures. No thanks!
