Yep. Rate Control is one of the most complex and nuanced features of real-world encoders. It's got a lot of psychovisual aspects, not just pure engineering. And choices made in each frame can propagate through the rest of the GOP, and getting that right is super complex. One of the secret weapons of x264 was cu-tree (ctu-tree in x265)

I hope Multicoreware could talk more about the current state of x266 encoder at IBC 2021!

https://multicorewareinc.com/news/meet-us-at-ibc-2021/

or even better, release x266 0.1 version.

For me this is the paranoia of the techno of the Asiatic world. Buy 8K 55 "- 98" for your street business as an advertisement. There are no winters so knock the wall over the TV. 4K magnified to 8K has pixels. Oh dear, then we'll add neo qled or evo oled so as not to scare the client off the street.
What for a home user 4K below 48 ". It does not matter most of this technology. Will the creators change old movies on vvc? They will not. Here only fans of mass events benefit.
What about professional 8K cameras when webcam or youtube reigns? For VIPs.

I don't know what the Panansonic has in hiding, but in Central Europe it isn't taken into account.
Sony and Sharp used to be the leaders. Where are they on the silk road?

To play VVC file with VLC.

Download O266 lib, libo266dec.dll file (by tencent): https://multimedia.tencent.com/resources/vvc-player

Put libo266dec.dll file into dir: VLC\plugins\codec

then play *.266 file

But you may see the framerate is incorrect, you need encode with new VVenC build, which has have new --fps switch for exact framerate.

Optical disc development ended with UHD Blu-ray, so 4K HDR HEVC. But streaming services absolutely adopt new codecs when they have sufficient installed base and compression efficiency improvements to merit it. And encoding is done from a high quality mezzanine, so the content creators don't need to do anything for customers to get the benefit of a new codec.

We won't be watching much H.264/HEVC/VP9 in 10 years!

Used heavily for premium content creation. YouTube is a slice of the market, but user-generated content as a business pales in comparison to that for premium TV and movies.

Reign where? Red Monstro 8K cameras have been around for quite some time now ehehehehe
I mean, a major licensors can afford to spend 60k for the camera corpse and a bit more for the lenses etc.
Over here (and keep in mind that we're broadcasters, so our productions are smaller - although we have made some documentaries and tv series and we might have a surprise for Christmas) we're still living with 4K as we're largely based on Canon C300 for documentaries and Arri Alexa LF for TV Series, so I think the major licensors, the big names that populate the market, would have no problem spending the extra buck, going the extra mile and start producing 8K contents soon-ish.
