That's what it was trying to do, but it just ended up being VRR number 3 instead  The PS5 has a really hosed up implementation of VRR that's neither here nor there. It's horribly mangled and doesn't even work in its 1440p mode.

the new VESA thing isn't a new spec, as I said it's the old spec plus some implementation quality standards beyond just accepting a signal the PS5 just supports the standard HDMI VRR spec, and not the weird stop-gap spec that AMD came up with 1440p monitors usually only support the AMD spec over HDMI (if anything)

This came up in the PS5 thread recently. Do you know if technically Sony could add support for AMD's HDMI spec, the way the Xbone and Series do (iiuc)?

depends on how the hardware of the PS5 is set up if i remember correctly, the xbox one systems drove the HDMI output directly from the SOC, but for some reason unknown to me the PS4 (and maybe 5?) used the displayport output of the SOC and fed that into a HDMI converter which may not support AMDs ad-hoc spec the fact that the xbox series supports the maximum HDMI 2.1 bandwidth while the PS5 is bottlenecked to a lower throughput, despite both being RDNA2 based, suggests there's some difference in how they're encoding the HDMI again repiv fucked around with this message at 18:40 on Aug 2, 2022 |

Man I watched the GN review of the dGPU intel drivers/software and big yikes. I’m a bozo in the tech world so I cant always parse everything but there’s so many show-stopping bugs that would make so many people just return the thing out of lack of troubleshooting knowledge or patience. I had low expectations based on what the thread said but it ended up being somehow worse, in installation of all places. Echoing seemingly everyone in hoping that they don’t call this an insurmountable obstacle and trash the entire dGPU concept forever.

Craptacular! posted:Intel dGPU is actually amazing as long as you want it for the right reasons (encoding) If Lovelace doesn't include AV1 (not sure if it's been confirmed) then the streamer meta will be to get a motherboard with two x16 slots and stick an intel GPU in there just for hardware encode (or just build a dedicated streaming capture PC I guess). Having an Intel GPU doing encoding while an Nvidia GPU games would work, right? Or would that cause weird driver mixups?

bigger streamers will probably still do av1 encoding using their streaming pc cpu's for a good while. of course, it all depends on obs support. currently you can use it using it when recording (because it's not supported on streaming platforms) what i still haven't managed to find out is how much it takes to transcode av1 into vp9/x264, since that's going to be the main hit on platforms like twitch and youtube? is transcoding equivalent to x264 transcoding, or is it significantly harder like, well, regular av1 encoding? the problem with intel gpu's right now is (also) that they currently seem to be way too unstable for any serious streamers to want to use them; these are people who postpone windows updates for as long as possible, because they keep resetting settings and breaking stuff all the time

not for the time being, no. they've never said much about it publicly wrt livestreaming, and codec/bitrate support is one of those things where each could stand out better from each other. twitch has offered some eta's for adoption, but i think that was generally pre-pandemic, so who knows what the pipeline is like now hopefully something will change when/if ada adds hardware encoding for it in a bit there's an old demo of av1 on twitch if you wanna test it, although i don't know how relevant it is now, given how much has been improved since. i don't even know exactly what they used for the encoding https://twitch.tv/videos/637388605 also worth remembering that youtube always transcode ingest streams, so there's not likely to ever be a "source" quality av1 stream unlike twitch who's more strict about bitrate and settings. so the subsequent sub-not-source transcodes are more interesting here. add to this that we should assume platforms will optimize for lower bitrate than higher quality in transcodes given the choice, since the ad-tech nerds think it increases engagement and watchtime kliras fucked around with this message at 13:20 on Aug 3, 2022 |

AV1 exists on the backends at Netflix already and their encoding architecture is pretty darn unique in the grand scheme of things given they do a pretty darn solid job of parallelizing encoding partly due to the strict requirements they put on the source formats for their content providers. It's definitely got a better overall future in terms of adoption rates compared to HEVC / h.265 and with the new addition of Apple adding AV1 support in their software things are getting started proper. The big hold in a way now is that there's 0 Apple hardware with any AV1 decode capabilities which puts AV1 mass adoption at least another hardware cycle out (beyond even the M2 CPUs). One reason why I'm kind of excited about FPGA-like capabilities on these SOCs is that it's an efficient, effective way to deliver firmware updates to older hardware to support features like new video codecs such as AV1. I'm not aware of Apple having such a heterogeneous compute setup possible yet but maybe they've got something ready soon enough. Given how long it took for h.264 to become mostly standard I'm sadly expecting to only get ubiquitous AV1 by perhaps 2026.

Especially since a lot of it is consumed over cellular networks, which aren't known for having super stable throughput.

even sub-second changes to page load can affect bounce rate for basic websites, so it figures that buffering a chunk of a video can also have a similar effect and now picture tiktok and its instagram and youtube also-rans where this is even more important for flipping through videos

I think the question was about how quality of a video ad alone affects the engagement and impression rates. I'd argue offhand as ignorant to the ad industry that it's not about quality as much as completion of an impression. For example, if you only can download N bytes like on an unstable connection set like hand-offs between towers that you may get cutoff before the completion of the download which can suppress impression statistics. Think complete download of a 200 KB animated gif vs a really onerous flash video ad from the 2000s. Also, it's always peculiar how super high quality YouTube videos are for ads that are cached and served with higher priority than the actual content from some backwater server way in the dusty archives of a datacenter because at least for myself I'll just skip the ad and have more patience for the video I meant to see. Granted, if the video is basically unwatchable because it's super unstable / shaky then that's a bounce.

With av1, you can have similar visual quality at a lower quality bitrate, which means the videos start quicker to no apparent visual detriment. And the reason a lot of people bounce off those videos is because they take too long to load at an acceptable visual quality.

the general idea of av1 simplified is that you can either get the video at twice the quality or half the bitrate compared to the original/h264/vp9 so for transcodes, you're never getting "worse quality". and of course, if the bitrate improves, your transcoding setting on youtube might automatically change from 720p to 1080p it's also not a binary thing, so a platform like youtube might start you off on a video at a safe, stable setting like 720p and then gradually increase it once engagement is more likely to be locked in, since videos are streamed in chunks and not as whole videos you need to buffer entirely. we're mostly talking about the first five seconds of coming into contact with a video e: fb kliras fucked around with this message at 16:29 on Aug 3, 2022 |

The longer-lived laptops have more than enough CPU power to software decode AV1, and phone refresh cycles are shorter, so I'd actually bet that AV1 adoption takes off running once iPhones ship with them, which is likely next month!

kliras posted:bigger streamers will probably still do av1 encoding using their streaming pc cpu's for a good while. AV1 encoding is more like x265 speed than 264. People have stuck with 264 despite large file size because, well, 265 is kind of janky in anything that isn't a cartoon, but until Turing it wasn't fast either. Intel and Netflix came up with a CPU encoder, SVT-AV1, that I have used in some :files: with ffmpeg nightly, and even though it's not fast even running at 265 Slow style speeds it's doing better quality for similar filesizes. Outside of encoding your "home videos" it's a bit more touchy For streamers, the other problem is hardware support. Twitch wouldn't switch to it because currently Apple products don't support it. Even the pirates will be kind of annoyed that Plex server doesn't work with it either. Which is why they should abandon both products for Android and Jellyfin, but that's for another time.

H265/HEVC is also wildly patent encumbered which has stalled adoption pretty hard AV1 is royalty-free so it's easier to work with from a legal standpoint

So if I want to decrease the file size of my partners videos without killing quality I should use AV1 then, right? Playback and encode time isn’t a huge concern really at this time. Just looking to be efficient with space because 4k60 takes up a loooooot more space than we assumed lol

Yes. Just understand that you won't be playing them back on low-power devices without hardware decode. These modern ultra low bitrate codecs are a lot of work to decode without acceleration.

Meanwhile I want to want more GPU horsepower added on top of my 3070 which sometimes feels lean at 1440p for the 10% of times I actually push the card to its limit, but most times it’s me playing freaking map games and my last GOTY looked like a PS1 game and the runner up looked like a slightly better PS1 game.

There are only two vendors who make sufficient small enough card for my application so I'm bit worried that this trend where GPUs consume more power and are even bigger means that there won't by any cards at all next gen that fit in my cases (nothing special, a Fractal R6 with storage layout, just with all the other PCI slots filled in with stuff and NCase v5) and I should just buy something already. It just happens that EVGA has no or low availability around here and FE cards are region locked out of my country so I might as well wait for the unicorn 4-series/7-series/ARC whatever that will fit in regular double wide full height full length PCI slot.
