#2Can we all just agree on using AV1 instead of another patent encumbered format?
Re: H.266/Versatile Video Coding (VVC)
#3Huh. I wonder how encoding speeds compare. I rarely chose h265 over h264 because similar levels of visual quality took massively more time.

How does x264 etc get away with it?
Re: H.266/Versatile Video Coding (VVC)
#5that sounds great, but this is a press release with no real technical details. can anyone in the know add some context? for instance, whats the tradeoff? I assume more CPU?
webrtc based video chats are all still using h264, did they not adopt 265 yet for technical or licensing reasons? what is the likelihood of broad browser support for h266 anytime soon?

#6Can anyone verify if this is a real number? It’s possible sometimes to make surprising claims (such as 50% lower size) by relying on unusual or unrealistic situations. I would rather if they use a standard set of test videos with different content and resolutions, and some objective measure of fidelity to the original, when quoting these percentages. But if the 50% number is real, then that is truly remarkable. I wonder how many more CPU instructions are required per second of decoded video compared to HEVC.

#7> A uniform and transparent licensing model based on the FRAND principle (i.e., fair, reasonable, and non-discriminatory) is planned to be established for the use of standard essential patents related to H.266/VVC.
Maybe. On the other hand, maybe not. Leoanardo Chiariglione, founder and chairman of MPEG, thinks MPEG has for all practical purposes ceased to be:

The disorganised and fractured licensing around HEVC contributed to that. And, so far, VVC's licensing looks like it's headed down the same path as HEVC.
Maybe AV1's simple, royalty-free licensing will motivate them to get their act together with VVC licensing.

Just found av1 is about 20 to 30% more efficient than h265. I guess there was no reason to use patented algs, but h265 is now significantly more efficient than av1.
I would still take freedom over patented software

#9Naively hoped I'd read 'this will be released to the community under a GPL license' or similar. Instead found the words 'patent' and 'transparent licensing model'.
I appreciate that it costs money and time to develop these algorithms, but when you're backed by multi-billion dollar "partners from industry including Apple, Ericsson, Intel, Huawei, Microsoft, Qualcomm, and Sony" perhaps they could swallow the costs? It is 2020 after all.

That's the direction everyone is going, so I think h.266 is an attempt to give vendors pause before moving to av1.
AV1 will probably win in most circumstances (big tech) but is unlikely to win where there are big gains to be had by reducing file size (broadcasters with gigantic libraries).
Broadcasters are also used to paying a lot and not getting much.
