off to bed now ... have a good one everyone!

morning folks!

good morning

beautiful christmas weather

at the pool

10c here. almost t-shirt weather :)

Rain here.

lol

troy_s: same to you

intracube: There is a great paragraph where he begins to discuss the problems with display referred imaging.

"...and archive it for an as yet un-invented display"

it'd be interesting to know how many post production companies and studios archive with that in mind

It is a good article.

Touches on just-enough to tickle interest in minds that haven't been exposed to some of the concepts.

intracube: Make no mistake, dynamic range is the next most compelling advancement. The HDR display at SIGGRAPH was the _only_ thing consistently with a group of folks around it.

Also, take note as to the default settings in a big box store.

The problem with 4k is that again, everyone forgets what DVDs brought to the table. I bang that pot every time a new thing comes out.

The two most compelling facets of DVD was, in no small terms,

B) Sound. DVDs ushered in home theater in a way that bulky laserdiscs couldn't.

DR is a part of image quality though

"new specification also will improve color gamut dramatically and offer a higher dynamic range"

Rather a lost cause.

not in parts of the world without reliable fibre

As in if I took a 2k HDR display and set it beside a 4k, I assure you that on a casual street 99% will take the HDR in terms of interest level.

It is an upsampled image in the vast bulk of instances, which has little gain over a sophisticated upsample at your media player.

Sure... An F65 can do a native 4k.

Which means after a typical 10 foot viewing distance, the difference is bugger all.

Whereas HDR carries across your whole viewing field.

DRM, proprietary viewers, no physical copy

but most people don't seem to mind

“Yet millions seem happy with streaming video, despite its shortcomings.�

So again, HDR carries down stream pipes.

It is that visceral "Sheesh what the hell?"

Your whole perceptual field shifts as your brain suddenly reads 3D cues in the content

And you know what: Most likely people buying a TV are soon buying HDR-TVs. When the markets start selling different HDR screens we will see

HDR screens are a ways off

The issue will be content.

So content would require a remastering

Interesting question. I suppose if a display is already color managed, and we can take chromaticity nightmare out of it, there is probably a reasonable curve that would permit "upscaling" existing content to HDR.

so even with DVD, it could look significantly better

pff. cheating :)

and in auto mode it will be over the top most likely

"Had" to watch skyfall, the best bond movie in terms of cinematography in my view, at a friends house last christmas. He liked his TV. I closed my eyes and listened to bond...

the color and brightnes management is the point why from the different HDR approches, Dolby Vision is the only I would aim for.

while dolby recomends finishing a 4000nits master currently (as long as no display supports PQs max of 10000 nits), you do trim passes for different capabilities which will be transported in metadata.

But no specifics about the real rendering. Will just be handled different on different sets anyway. God for live TV but bad for movies.

irieger: All "4K" is up samples.

In terms of HDR, the Lenovo display as well as Christie was stunning.

;)

Not an easy problem to solve.

off to bed
