I’ve pretty much deleted from my grey matter memory everything associated with VC-1 or the rival codecs of that time. With regards to AV1, I think the film grain synthesis is a pretty good feature for those who employ that codec because you can just figure that if there wasn’t this option, the streaming content deliverers would simply DNR the content to death to save on bandwidth. There are comparative subjective quality results/pics pointed out by Andrey at about the 23 min. timestamp of that above linked video to show the value of their film grain synthesis.

I'm misremembering re: the codec but the common link is HD DVD: something called Film Grain Technology by Thomson was actually added to the spec e.g. https://www.engadget.com/2006/07/06/...d-dvd-finally/

A tech piece on it is here https://hopa.memberclicks.net/assets...gt_hpa2006.PDF which is why I'm not wowed by a new mention of pretty much the same thing over a decade later. Not that I think such a concept wouldn't be useful to have around - it'd be amazing if there was an on/off toggle so people could watch the DNR'ed version if they so pleased - I just hope it gains more traction than the HD DVD iteration did!

The film grain synthesis process for the new codec AV1 is being introduced by the streaming community (Netflix, YouTube), who are motivated to compress at the lowest bitrates possible in order to save on bandwidth with their non-physical media delivery methods. For example, one of the taglines for the recently concluded Picture Coding Symposium 2018 (https://forum.blu-ray.com/showthread...t#post15176010) was –

“How will we stream a perfectly crisp 4K-HDR-WCG episode of Chef’s Table without requiring a 25 Mbps broadband connection?”

P.S.
You remember this engadget article from thee old days? - https://www.engadget.com/2006/07/06/...ay-it-fake-it/ (HD DVD had less bandwidth capability as well as smaller disc capacity as compared to the Blu-ray format).

since then -> https://variety.com/2018/digital/new...ls-1202818029/ , the Variety article is a little misleading/incomplete in the sense that the several redbox kiosks that stock ‘4K UHD’ discs as pictured on this and the last page are actually located well over 30 miles away (and in a different county, to boot) than Los Angeles.

Calculating the viewership numbers for the month of June for this thread…..
1,255,502
- 1,158,330 (from May…. https://forum.blu-ray.com/showthread...y#post15125932 , i.e. May figured in at ~ 68,300 views )
__________
= 97,172 views for the HDR Discussion Thread for June

^ Dang good viewership for a summer holiday get-away month. Keep in mind though, for July, many of us take vacations (including me, and I don’t post when I’m on holiday), so don’t be at surprised if maybe the viewership total for July drops some…. unless other members fill in to carry on, because the numbers show that similar to this vintage commercial, when the HDR Discussion thread talks…..people listen -

When EF Hutton talks, people listen - 'Restaurant' commercial - YouTube

I'm not here to score points for HD DVD, just remarking that this isn't the first go-around for such re-graining technology (which as a tool by itself I wish could be built into every player, **** that noise reduction, I want a noise additioner with various vintages of grain to choose from) and that I hope it gets better mileage this time around.

PS

If it was such a daffy thing back then it's just as daffy now, and both implementations are in service of mediums which have less than stellar bandwidth, funnily enough.

HDR or only just SDR viewing, if you guys didn’t get excited over watching yesterday’s World Cup matches yous be brain dead.

Thought Brasil Mexico was boring AF, redeemed by an absolute cracker with Belgium Japan. Normal service resumed with Sweden Switzerland mind you, zzzzzzzzz

If AI can help produce better encodes than some of the filth being released these days then send in the machines! Perhaps we can map David M's brain and create an army of exceedingly competent compressionists?

I think Deluxe entertainment services group people, especially those with years of experience (carry-overs from GDMX) can also hold their own in terms of video compression and authoring.

We don’t have a team in the World Cup this time, but U.S.A. folks y’all have a safe and happy 4th of July!

No doubt on Belgium v. Japan. As to Brasil v. Mexico, I thought 1st half was dyno-mite. 2nd half, less so, because Mexico couldn't maintain that frantic pace. Brasil looked so much better than four years ago.

Some very good news here for hdr fans wanting more content..

And that goes for today too with Columbia v. England. Like Steed, I had a feeling the 3 Lions would show up to play….https://www.youtube.com/watch?v=JpyR-Ym7Hck#t=1m56s

To those who may have missed it live, I would suggest you see if you can catch a tape delayed rebroadcast, as this match is definitely must-see TV at its finest!

UFC 226 will be in 4K HDR on DirecTV. First ever MMA event in HDR.

It's too bad Canada is so far behind. No HDR for us yet.

And to all our millions of soccer Moms and Dads from sea to shining sea, who this week are being asked by the kids ‘why aren’t we in the World Cup, Mom, Dad?’……educate yourselves and your children as to some of the reasons why by listening to the free audio preview and then perhaps purchase the book….https://www.amazon.com/Whats-Wrong-U...0729890&sr=1-1
