Word is it’s going to be difficult, but they’re still hoping to meet a target date of late December wrt a commercial installation for Angelinos, don’t turn skeptical if install gets pushed back a little later.

There could be any number of reasons for the delay, I'm supposing, but I wonder what the power consumption is on a FALD (full array) theater display, vs. a 2K or 4K digi projector. Even so, there would be a new electric run to the front of the stage to feed the display panel(s), and associated safety precautions.

Red updated their VistaVision sensor to what is now called the Monstro 8K VV. Specs are the same, but apparently it has better dynamic range and color.

Maybe someday before you and I kick the bucket we’ll get a live HDR broadcast of SNL and after-the-fact, for those who missed the broadcast, on YouTube, until then SDR will have to satisfy us ….

z, have you shot anything recently in V-Log (Davinci Resolve 12.5 for HDR mastering) or simply straight HLG (with no real dedicated grading) to your channel on YouTube?....last I recall was your footage of the eclipse as seen from the Seattle area.

Apart for that eclipse footage, I previously shot these two clips on GH5 in V-Log:

Real 4K HDR: Seattle Dusk in HDR (Chromecast Ultra) - YouTube

Real 4K HDR 60fps: Times Square NYC during the day in HDR - YouTube

Both clips are shot anamorphic.

In other news, I just finished color grading Cosmos Laundromat for HDR.
If your device supports YouTube HDR, you can see it there.

I also made a version that you can download and play directly on a 4K HDR TV:

I switched from Resolve 12.5 to 14

Comcast is now distributing 4K DVRs (XG1v4) that can do HDR. Within a year I feel there will be enough of a demand for 4K HDR content. The next Olympics should be available in 4K HDR.

I am watching Star Trek Discovery on Netflix and its HDR, but 1080p. Is that a first

I'me jelly. Here in the US we are stuck with f-ugly CBS

Rocky, did you guys scare away member BrownianMotion (strong HDR10+ promoter) or is he just resting?

Choosing Encoding Parameters for High-Dynamic Range Streaming

High-Dynamic Range (HDR) could be a very powerful storytelling tool for cinema and television. Yet, HDR's newness also means that we don't have consensus on how best to prepare and distribute HDR content to consumers. This paper will provide data and analysis on the impact of various HDR encoding options on video quality and bitrate. Specifically, this paper will examine permutations of PQ, HLG, Y'Cb'Cr', ICTCP, encoded resolution, and bitrate using open-source encoders such as x265. Video quality for each permutation will be measured using publicly-available non-proprietary objective video quality metrics.

The key takeaway will be unbiased data and analysis for video quality and compression efficiency that can be used when designing HDR streaming services.

Background: Today, we have two different ways of mapping light to HDR code values: Perceptual Quantizer (PQ) and Hybrid-Log Gamma (HLG). We also have the option of representing color as either Y'Cb'Cr' or the newer alternative ICTCP. For HDR adaptive bitrate streaming, we need to choose which compression levels and encoding resolutions to use when we create adaptation sets; but we don't yet have a complete understanding of how resolution and compression could interact to alter the highlights and deep darks that make HDR so visually potent. When viewed altogether, the many permutations of HDR encoding can make designing an HDR streaming service too complicated and uncertain. We need a simpler way to make the best choices.

Hooyah! I was wondering if you’d tried it out yet….others have been a bit slower when jumping feet first into the new version.

Good job.
I am somewhat familiar with the short as having seen several scenes analyzed in professional study group meetings as potential HDR test content wrt encoding, e.g. –

I started using it since beta1 and opened a few bugs. It was a rough few months

Yup, that's exactly what I was hinting at.

Out of all the video guys (be it journalists and/or professional video engineers) who preach online or at trade shows/conferences about human vision and dynamic range or human vision and resolution (its capabilities/limitations) Sean’s probably the only one I can think of offhand who could actually tell if shown two unlabelled pictures - - which one represents a pic of the topography of the cornea vs. a pic of the layers of the retina on an OCT….which is quite basic to those involved in imaging science.

The rest of the soapboxers when speaking about the human visual system (HVS) remind me of grade school kids presenting term papers based on a couple hours of research with some simply being better at their homework assignment than others, rather than having any real formal training and firsthand experience.

No matter what the venue (he was also speaking at IBC 2017), I think Sean’s presentations are worth a listen for attendees of the SMPTE 2017 Annual Technical Conference & Exhibition interested in cutting edge concepts geared toward implementation.
