Not sure who that Glenn Fry is. Must be the Vegas knock off.

Edit: I still do not understand how a studio exec thinks that dual dynamic formats on a disc will be more profitable. It has to cost more to author a disc with both, correct. They basically will sell the same amount of discs because they have exclusive content and if the consumer does not have the particular dynamic function then they will view it in HDR10.

Well, it turns out Vincent Teoh, misunderstood Sony documentation, because his new video has clarification from Sony. Sony currently has no plans on adding HDR10+ support.

Isn’t HDR10+ the HDR protocol that IMAX Enhanced chose? And Sony’s a partner in that venture. Won’t they have to support HDR10+?

Supposedly plain HDR10 is “good enough” for the video, even though some “DNR” type processing may be applied. 10+ will just be available for some Samsung and Panasonic owners. It’s the audio that gets more attention and gets some tweaking and bass boosting I think. (For those with IE capable AVR’s and pre-pro’s.) Now I seem to recall you have one of those.

They seem to be dumping the already baked 12-track IMAX mixes into a DTS: X form as it's already in a fixed 7.1.4 print-out, which is close to IMAX's speaker layout and the IMAX Enhanced mode in the receiver or pre-amp further boosts the bass volume (bypassing calibration settings).


There seems to be confusion as to whether it has a matrixed Center Height or a newly added fixed object acting as a channel, however, DTS seems to be coming out with DTS: X Pro with mention that it goes beyond the 11.1 limitation of standard DTS: X for the home. Whether it's true and they started using working pannable 3D objects or they're BS'ing and just matrixing with Neural: X to fill in the gaps is still unknown. Either way, according to FilmMixer on the AVS Forum, it's still behind Dolby Atmos in its capabilities when the Atmos track is not just a fixed print-out like all Disney Atmos titles (and a few other studio releases).



There has been ZERO mention of IMAX Enhanced titles using DTS: X Pro mastering and encoding.


So far, to me and some others, IMAX Enhanced is pretty much a marketing ploy in order for IMAX and DTS to gather extra fees to help stay relevant.

__ IMAX Enhanced propaganda sounds like THX Certification all over again.
...Sounds closer to the theaters by punching a badge on some AV products.

The more logos the more people want them all; logos collectors.

I want it too, just to feel safer than sorry of missing the free ride.
Disney/Marvel flicks on 4K Blus can use an extra dose (boost) in dynamics and in the LFE channel...say 10 dBs.

...And HDMI 2.1 certification (with 8K and HFR & HDR10+ passthru).

* I also would like to see more manufacturers get on the Auro-3D bandwagon (best stereo music upmixer into multichannel sound...Auro-Matic 2D & 3D).

Auro is going nowhere fast. All the Auromatic upmixer does is duplicate the lower level information into the overheads, adds delay and sweetening. It doesn't steer sounds with a best guestimate like Dolby Surround or DTS Neural: X.


Auro3D is basically like standard DTS: X, but the resolution of the extra channels isn't as good as the mains because of the way their Octo-something encoder folds them into a standard PCM track, which is then compressed with DTS Lossless.

Lol. Yeah, my pre/pro has the imax enhanced. Not much I can do with it. Will probably have to double dip on Venom when it’s released in IE. I thought I read/heard somewhere that imax enhanced chose the 10+ protocol for their HDR du jour. I guess I misremembered. I tell ya, the ol’ medulla oblongata ain’t what she used to be. So it’s just regular HDR with a sprinkling of imax DNR? It’s like ordering the lobster and they bring you a crayfish.

I hope that’s not the case as that’s one thing you really need. You can afford to lose some cells higher up due to a lot of Tequila Sunrises….

Approved for Distribution for Comments 16 November 2018
Digital Cinema Initiatives, LLC, Member Representatives Committee

The proper presentation of a High Dynamic Range Digital Cinema Distribution Master (HDR-DCDM) requires the definition of an HDR Reference Display and controlled environment. This DRAFT specification defines the HDR Reference Display and specifies the tolerances around the critical image parameters for Review Rooms and Exhibition Theaters so that consistent and repeatable color quality can be achieved.

D-Cinema Direct View Displays provide the potential for an improved high-quality image through significantly increased peak luminance and dynamic range, but may also be used to present legacy content. This DRAFT specification defines performance requirements for such displays that are unique to D-Cinema Direct View Displays. These requirements will ensure interoperability and consistent quality of image content on the new generation of d cinema displays.

These documents are not DCI Specifications. These Draft Version 0.9 documents are distributed for review and comment prior to publication of a final requirements document by DCI. Recipients of these documents are invited to submit their comments to DCI.

@Penton-Man, are you attending HPA Tech Retreat this year?

I'm signed up and would love to finally meet.

My my, and back yet again to the west coast….you do get around.

Nope, not this year as I’m otherwise committed. Perhaps someday our paths will physically cross. Came close at CEDIA 2017. In addition to the HDR discussion at the retreat, check out what Peter P. has to say about “8K: Whoa! How'd We Get There So Quickly”? I'm curious.

[Robert Zohn]

Do you have a link to Peter P's comments. I'd love to read his opinion on this.

At one point Sony didn't think they needed dynamic metadata or dynamic tone mapping. There was rampant confusion and misinformation being spreaded about the nature of dynamic metadata and it what represented, concerning high peak nit displays vs lower peak nit displays.

[Robert Zohn]

I did not ^ know that.
