AV1

How was the AOMedia AV1 idea. Which tools were under consideration after 0.0.1? What decoding complexity was expected? Why PVQ wasn't adopted? Is expected from AV2? What are alternative to the PVQ for optimizing rate distortion and get all the 13,8% HEVC gain?

Watch it all and at 34:00 sample images

Ok so after a full test with my 4k 24fps 30sec clip of Avengers infinity war (HEVC) we are with :

SVT-AV1 1.4.1 no grain denoise off: 19:18 minutes / 0.82 fps / 9.2% of source

SVT-AV1 1.4.1 grain synthesis 20 denoise off: 20:34 / 0.76fps avg / 9.2% of source ( -6.05% speed )

SVT-AV1 1.5 no grain denoise off: 15:20 minutes / 1.18fps avg / 9.356% of source ( +20.75% speed )

SVT-AV1 1.5 grain synthesis 20 denoise off: 16:09 / 1.09fps avg / 9.381 of source ( +16.11% of speed )

SVT-AV1 1.6 no grain denoise off: 10:57 minutes / 1.43fps avg / 9.168% of source ( +44.89% speed )

SVT-AV1 1.6 grain synthesis 20 denoise off: 11:43 / 1.33fps /9.192% of source ( +40.41% speed )

which means 20% speed boost between svt-av1 1.4.1 and 1.5. And another 30% between 1.5 and the new 1.6.

GG devs, you are amazing!

( this is with preset 3 crf 18 at 4k and the settings for grain when used, all in handbrake. mind that this is with a Ryzen 5800X3D with a little bit of downvolting for perf )

This whole situation seems like a perfect opportunity to use highly efficient lossy image compression.

Same goes for video, though I'd guess encoding AV1 video on a Mars rover might be asking a but too much, it might be worth a try with VP9?

What the fuck did you just fucking say about AV1, you little bitch? I'll have you know I graduated top of my class in FFmpeg, and I've been involved in numerous secret encodes on nyaa.si, and I have over 300 confirmed encodes. I am trained in gorilla debugging of day 0 appveyor releases and I'm the top shitposter in the entire AV1 subreddit. You are nothing to me but just another video file. I will compress you the fuck out with efficiency the likes of which has never been seen before on this Earth, mark my fucking words. You think you can get away with saying that shit to me over the Internet? Think again, fucker. As we speak I am contacting my #daala IRC across the TOR and your IP is being traced right now so you better prepare for the DDOS, maggot. The storm that wipes out the pathetic little thing you call your seedbox. You're fucking dead, kid. I can be anywhere, anytime, Chrome, Firefox, Opera, you name it. And I am supported in over seven hundred ways, and that's just with my in pre-alpha decoder. Not only am I extensively trained in batch scripting, but I have access to the entire arsenal of the Amazon Web Service and I will use it to its full extent to wipe your miserable h265 encodes off the face of the internet, you little shit. If only you could have known what unholy retribution your little "clever" comment was about to bring down upon you, maybe you would have held your cheetos covered fingers of the keyboard. But you couldn't, you didn't, and now you're paying the price, you goddamn idiot. I will shit fury all over you and you will drown in it. You're fucking dead, kiddo.

I decided to ask /u/stevenrobertson (youtube engineer) why are AV1 videos using such high bitrates, here is hour exchange:

Me:

Hi, I'm a moderator of r/AV1 and community noticed a weird trend with AV1 videos on youtube. The whole point of AV1 was to deliver better quality for smaller data streams but apparently it's not the case right now.

AV1 files have larger bitrates than VP9 and we are somewhat confused by this. Do you have any information that you could share with the community, that would help us understand how youtube is planning to use AV1?

stevenrobertson:

Hey Dominic! AV1 is expected to save YouTube and its users a ton of bandwidth over the next decade or so. Our goal today is entirely around driving adoption, making sure hardware decoders land where they need to and are reliable and well tested. We're explicitly targeting fidelity levels that are higher than VP9 for now as part of driving that adoption, making sure decoders are fast and reliable and making sure AV1 always looks great. This is still just the start of the AV1 rollout. HTH!

Encoded a video on FFmpeg using -pix_fmt yuv420p10le command, and it is stuttering a lot, same thing doesn't happen with 8 bit.
