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. |

MediaTek has announced Pentonic 2000 SoC which supports VVC. Finally!

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. https://www.samsung.com/pl/tvs/qled-tv/highlights/ https://www.lg.com/pl/oled-tv/2021/s...E&gclsrc=aw.ds 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? Last edited by Jamaika; 20th November 2021 at 14:23. |

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.

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

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.

Shooting in 8K, sure. That's been happening for a while, and a number of movies and TV shows shot with 8K cameras are already available. Post and distribution in 8K is a whole other matter, and I'm not aware of any real-world titles using it or even seriously contemplating doing so. The extra costs far outweigh any potential added market value. 4x more pixels mean new monitors (and there aren't any DisplayPort 8K HDR monitors), 4x the storage, 4x the RAM, 4x longer rendering, projectors can't be used for previews, and a whole lot of other hassles. Plus, since 4K and 8K look identical for the 99.9% of premium content that's at 24p, determining that 8K is actually working is a huge challenge. Valuable 8K is a lot more likely at 120p. But that's pushed the delta up to 20x storage, 20x render time, another generation of studio monitors, etcetera. Moore's Law is a wonderful thing, so even if 20x is impossible today it'll be no big deal in 10-12 years. |

There are ofc other tech areas that improves on this in other ways, just look at what apple is doing with their silicon and ecosystem, and what you are able to do on those machines in terms of video compared to what was needed for that a couple of years ago. Not that their more recent chips are not impressive when it comes to transistors as well, I think that Apple is in a rather unique situation here; they are so profitable elsewere and has such a huge volume so it wouldnt surprise me if they actually have relatively low margins on these parts.

For the film industry, it can be as much about what's possible as how much it costs. Lots of tools that can do 4Kp24 today simply don't have any way to scale to 8Kp120 at any costs. You can squint and imagine how a cluster of beefy servers chock full of a6000 GPUs and clever tiling software could do the same thing. But unless that software and hardware is available, it just isn't possible. And regressing from real-time previews to "I'm going to render the shot now, should be done after lunch" is a huge deal. It's the same way you can't buy a gaming rig that can do 8Kp120 for 8x (or 80x) the cost of one that can do 4Kp60. There is only so much parallelism that can be taken advantage of by the underlying software architecture before an Amdahl's law limit gets hit. SLI was never 2x the perf, nor was TLI. |

And sw-encoding is not the only factor in the workflow if 8k will become valid or not, I have tried the M1 for video editing 4k HEVC & Prores files, and what that SoC achieves at this powerdraw is simply astounding. And its not just the CPU-cores I'm refering to, it's all the other stuff on the SoC as well in combination with stuff like Metal (or what Intel is doing with oneAPI) that really displays that there is a promising future even without Moores Law.

x265 itself got a bunch of ARM optimization check-ins this year that have more than doubled encoding fps on M1. Talking to colleagues deep in this stuff, there isn't anything fundamentally better about the x86-64 instruction set for encoding. It's more than Intel and AMD build big beefy CPUs with lots and lots of cores and cache and SIMD. |

A metaphor would be Xbox Series/PS5-only games. They can rely on SSD storage, DirectStorage like SSD to GPU transfers, etc within a tightly defined architecture. Like the M1, they can outperform a general purpose computer setup at a fraction of the cost. |

Nothing official, just rumours, but still... Quote:
Really? I thought ARM were meant for mobile use and had fewer transistors and those transistors were actually made to use the smallest amount of energy as possible at the expense of performances. I also thought they had different registers made just for stuff that you use in a mobile like TLS computations for websites and some ai things for assistants etc. Of course something like an encoder could make use of some of those registers as well for its calculations, hence speeding things up with the manually written intrinsics like x265 has done, but I thought the ARM registers were no match for the x86_64 ones (SSE/AVX). If what you're saying is true, this opens the door to lots of new scenarios. |

But the general point that we can anticipate increasing compute/$ for at least a couple more decades is important, even if the rate of improvement is slowing down. Digital media stuff consistently gets some of the biggest generation-on-generation performance/efficiency improvements, as we can leverage a whole lot of SIMD and parallelism. |

Not really useful in terms of the whole industry "codec usage" but for me there were two interesting point. 1. Quality is not even the top 5 features respondent care about. Which is what I have been saying for sometime, if you want higher quality, go higher bitrate or better codec than H.264. It is no longer much a tech issue, but a cost issue. 2. It is not only me and a small group of people screaming for better low latency video. Live Streaming is the one that makes money, and also the one which requires most attention from codec usage.
