Just like last thread, I have disabled SSIM cheating in AV1. I'll be posting AV1 webms on umigalaxy here:
https://umigalaxy.com/explore/general/595-ssimav1-script-v20

These parameters force AV1 to heavily optimize for perceptual quality and generate x264-like SSIM scores.

Is av1 the best option nowadays? I thought hevc was the high end stuff

Dam I got something wrong.

SSIM: 0.999 @ CRF 60

MP4= 67478 KB
AV1= 2749 KB
**** 95% filesize reduction achieved with AV1 ****

If anyone could help me figure out why the SSIM is being parsed so completely wrong, I'd really appreciate it senpai.

Sweet merciful Joseph, where is this 0.999 SSIM score coming from. There shouldn't be a 0.999 SSIM score on a preset 10 CRF 60 AV1 encode, like AT ALL.

Nothing in this script assigns SSIM as 0.999 as far as I can tell...

OP here: is that from chatgpt? I appreciate you trying to help but it's mixing up windows batch scripting with powershell, I'm only using windows batch scripting (ie the .cmd extension thing).

I've handmade my script for days now. What's beyond confusing is some videos do seem to be reporting accurate SSIM scores most of the time. It's like there's a demon insertng 0.999 into my script randomly.

HOLY SHIT I THINK MY COMPUTER IS HAUNTED

Yeah if a jeet hasn't figured it out yet, then AI is kind of worthless right now since jeet answers is what AI is trained on irl. Modern ones just seem to be getting better at realizing most of those jeet answers are wrong and trying to correct them. Don't trust it too much, at least for now man.

Anyway I'm gonna take a long walk and have a big dinner, I tend to panic and overcomplicate things to the point of never fixing them when I'm stressed. I know for a fact it has something to do with that SSIM parser, the demon is hidden in that thing somewhere...

Not OP but Av1an seems to do what OP wants.

https://rust-av.github.io/Av1an/Cli/target_quality.html

However I can't get it working on windows, I get this error:

thread 'main' (2136) panicked at C:\Users\runneradmin\.cargo\registry\src\index.crates.io-1949cf8c6b5b557f\vapoursynth-0.5.6\src\vsscript\environment.rs:70:38:

note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

It seems that the most exotic aspects of AV1 video encoding are currently only attainable for Linux users.

>AV1 doesn't play on my iPhone
huh? my 3 year old iphone does av1 just fine

>>108900378
No? AV1 encoding had been easy for windows but you do need to do some research
https://github.com/LastBreeze/Auto-Boost-Av1an-portable
Here a script that does av1an and autoboost if needed on windows,even option to pick which svt-av1 fork

why are they kidnapping a penguin wtf

>>108898704
nice ai slop faggot

>>108898329
see
>>108900763
There are better metrics and better scripts for automating av1 encoding. CRF 60 will block nearly anything at 1080p and isn't even worth encoding/scoring. Likewise preset 10 disables many important parameters for miniscule speed gains.
