The claim it contains 12bit data on DV I'm skeptical. Mainly because of DV documentation, HEVC docs, etc. Anyway for the CG sample, maybe fix those minimum posterizations with a full range 10bit, static metadata signaling. Certainly there no need to up 4X coding "cost" for now in which no...

Sony BVM-300X true RGB OLED; reference tracking. Sent from my Moto G using Tapatalk

PQ , HDR10 or Vision only "expand" range for highlights. Thats why the focus on 1k, 4k, 10k nits. Sent from my Moto G using Tapatalk

Teorically, but other aspects are not future proof. Like the change from 10 to 12 bit. The tradeoffs are not clear for the early adopter. Most likely UHD Premium "2" will change everything and provided the short window of firmware support for the TVs. The effective long term support is...

Maybe devs and gamers are trying to find the best hardware to calibrate for... There is a history about how BT.1886 was standardized... IIRC Famous director/color grading person had a professional CRT calibrated for the best filmic look used for many years in the industry with analog film...

Vision is PQ2084 the max is 10k nits but very coarse. Only helps highlights. HLG is 5000nits max but nicer curve on the shadows. Sent from my Moto G using Tapatalk

This legacy is the new "interlaced" versus "progressive"; REC.2020 is really limited not even allows full range. BT.2100 allows fullrange, but again the HDR curve salad means each HDR10, HLG or Dolby PQ have different choices on this. Narrow range were used to calibrate noise at analog...

Samsung KS is excellent, but no info if it will support HLG. So for future proof HLG is essential Sent from my Moto G using Tapatalk

BBC HLG also takes into account background luminosity. From 5 to 500 nits The "limitation" is a 5000nits maximum curve. Sent from my Moto G using Tapatalk

Found a good PDF to prove my point. http://www.compression.ru/download/articles/color_space/ch03.pdf Remember why even today there is the YUjv limitation of 16-235 from RGB. Most people get confused and in practice there is a loss of alrowed codewords. Then more banding effects because the...

Like I said the were really not good arguments to not include in the first PS4/XBO. Even Nintendo should have pushed this . Hell some legacy texture; formats could been scraped for a custom die. Sent from my Moto G using Tapatalk

From the links in my earlier post... The average picture level will remain 100nits. So only highlights benefit in the way pq2084 and 10bits code words were chosen. My opinion is content creators and the console industry has to pressure for a good standard in this way what we call 10bit wcg...

Earlier in this thread there were comments on blacks in HDR, HLG versus Dolby Vision, 10bit PQ or more. "4000nits come from Dolby Pulsar display" http://www.lightillusion.com/uhdtv.html Here many points are addressed, problems with "current" HDR certification... My additions by reading...

GPUs texture units support a limited set of formats based on power/speed constraints. The random way textures are accessed, limits the compression techniques used in those formats. For sure people have written innovative ways to pack textures, in the form of shaders/software. The problem...

Search the forum there was good discussions and comparison of ASTC versus BC6H/BC7 (current formats). Here is a nice presentation: https://www.slideshare.net/mobile/IntelSoftware/in-the-trenches-optimizing-ue4-for-intel Sent from my Moto G using Tapatalk
