And AV1 is really good. I'd expect a reduction in bitrate by 10% versus VP9 still results in higher quality. IDK, it seems like youtube quality is pretty good these days. They use good codecs now, unlike the VP8 days. If you compare 4K movie trailers and other stuff that's not a talking head, they're delivering bitrates that are at least the same ballpark as netflix.

And to be fair to YouTube, a lot of people just still have zero clue how to encode video for YouTube, especially huge channels like IGN. The new Moon Knight trailer from Marvel also looks like absolute garbage (in terms of encoding), which blows my mind for such a big company.

Combat Pretzel posted:I doubt ISPs have stopped their "Youtube/Netflix needs to pay for the bandwidth they use on our networks" shpiel. It's probably partly related to that.

I know a little less about video compression than I do about audio compression, but anyone with a confetti cannon or the equivalent After Effects filter can demonstrate how quickly things can get bad the same way that songs (even officially-uploaded ones) can end up sounding like vocal fry: https://www.youtube.com/watch?v=Gtyi1vvXxKY (Towards the end of the song, the crescendo is so powerful that it breaks most audio compression algorithms, and certainly all the ones offered by youtube - if you listen to a good FLAC rip of the song you'll hear very clearly what I'm talking about) BlankSystemDaemon fucked around with this message at 20:17 on Jan 18, 2022 |

BlankSystemDaemon posted:Youtube is a lot more hostile against ISPs than Netflix is, though; the latter has the OpenConnect Appliances that any ISP can setup in their datacenter racks, which functions as a cache for Netflix content. Netflix probably has well under 1% of the data that Youtube has though.

As of today, Youtube is plastering recommended movies all over my home page. Is there any nice extension made to get rid of this? I doubt Youtube would be kind enough to let me disable it on their own, even if I don't even watch movies and would certainly not pay Youtube to watch them even if I did.

I am curious how video delivery works at an as needed basis. So they cache it at edge locations, but how does delivery work if you've got hundreds or thousands of people asking to watch the same episode of a show? Like, are instances created when an episode is queued up and customers connect to it? Obviously outside of the scope of this thread but just a random thought I've never explored before.

Freetube for Windows or Newpipe for Android have been good at giving me exactly what I want based off of my subscriptions. Plus you don't actually have to log into a google account.

I mean, it's not like it's a new thing, and people need to get paid, but something clicked very recently, and this... SEGWAY! LTT STORE DOT COM! AFFILIATE LINKS! SPONSOR! etc blah blah... ...got reaaaally grating. When their upcoming labs stuff is gonna tear a hole into their financials, it's probably gonna ramp up some. I guess the other activities of LMG don't generate satisfactory revenue. Or it's simply just MONEY.

Youtubers who try and do knowing winking links (Linus) and subtle hard to notice transitions (Rene Ritchie) into ad reads infuriate the piss out of me. You know people are just going to skip past it so just say "now for an advert" like Michael Fisher does, and he's even started marking out the sponsor spot as a Youtube chapter (and before that had a big "Sponsor Message" box on screen during it) so it's easy to skip.

Most, maybe all, of LTT's video's for a while now have had the main promotion/sponsor ad listed as a chapter, but not the inserts they toss in during the video.

BlankSystemDaemon posted:I've seen a lot of people say it's better, and it may very well be - but where are the SSIM and PSIM comparisons? the only one that says AV1 isn't as good is Fraunhoffer, who are not exactly a neutral party (or it could be explained by their testing being in 2016 while the code was still very alpha) BlankSystemDaemon posted:I know a little less about video compression than I do about audio compression, but anyone with a confetti cannon or the equivalent After Effects filter can demonstrate how quickly things can get bad the same way that songs (even officially-uploaded ones) can end up sounding like vocal fry: So I don't have a lossless to compare, and honestly I'm not the best at ABXing encoder artifacts in the first place. But that song is clipped to hell. It's not "too powerful", its flattened against the wall. I'm kinda doubtful whether what you're hearing is encoder artifacts or just a song with terrible mastering. Most audio problem samples that show encoder problems are not songs that sound like that -- encoders do square waves just fine. If you're serious about comparing encoders and poo poo you can't just compare lossy vs lossless. You have to blind test them and, before making quality judgements, prove that you can tell blind samples apart.

I don't think I'd still be watching many youtube videos without sponsorblock. It arrived just as I was starting to unsubscribe from some. Even just blocking the "like and subscribe* stuff and the overly long intros makes it much better. If it could block the overuse of "guys" and everything being "super" then I'd be even happier

Klyith posted:https://en.wikipedia.org/wiki/AV1#Quality_and_efficiency, there are results from a bunch of different research papers you can dig into Also, did you read any of the articles? Almost all of them measure structural similarity (or even more laughably, PSNR) whereas what I'm asking for is both that and perceptual similarity (preferably at the same time, since that tells more than either alone does). All of the research done on AV1 is on researcher-chosen videos (which can be an issue, but let's assume it isn't) as well as settings that've chosen based on whatever optimizes for the best quality at a given bitrate. That latter is the important part, because it's not what Google are targeting; even if we knew their exact encoding choices (while I haven't looked extensively, I've not found anything conclusive - but if you upload something following exactly their recommendations it still gets re-encoded, so they're doing something else), I'm pretty sure we can guess that they're more interested in what gets them the lowest bitrate while still having passable quality. That's a distinction that matters when you're measuring PSIM. As for Comforting Sounds, the mastering of the song isn't the problem as it sounds great on the Frengers album or ripped as FLAC - it just happens to be a song where the crescendo contains so many things that the psycho-acoustic properties of most lossy codecs break down unless you do CBR at the highest bitrate. However, it's also a good test for this exact reason, because you don't need a blind ABX test to hear the differences in the FLAC encoding vs VBR in the low-140kbps- ie. what the OPUS encoding is for the version I linked, but even if it was AAC-LC (which is what youtube recommends), it still sounds like vocal fry.

The practical and money-conscious may take a long break from upgrades, but they'll be back. What you have to worry about is the pipeline of new people who are getting shut out. First time builders generally don't start with top-level parts, they start with budget or mid-range ones. They're the ones who have absolutely *nothing* to buy, and that's your pipeline for the future. In a shortage of fabs & ram, you can make 2-4 low-end GPUs for every high-end one. If both Nvidia and AMD had concentrated on maxing the number of boxes on shelves, it would have been better for everyone but the shareholders seeing record profits.
