There's more and some of these can be false positives. There will probably be hidden ones now and later especially when it's a twitter screenshot with no relevant words used to bypass obvious inpsection.
Good luck void-san, thank you for being someone who does something about a problem instead of just screaming into the abyss like everyone else.

I'll probably get banned but maybe it will reach out to a few anons from the past banned thread that were complaining about wanting a separate /ai/ board like a few days ago.

During a conversation with @webpgoy we cooked up an idea for an image tab in the settings. Right now all the static image options from our image processor sharp are available for testing.
I already noticed setting the effort to 6 increases the processing time by a ridiculous amount so maybe that should be capped to a lower value.
The idea right now is to test what makes sense, right now when you create a new preset it uses the default values so we can even double check if the default values make sense, for example a 800kb jpg is turning into a 1.5mb webp, which seems counterintuitive.
ps: animated webps and gifs are left alone, these settings don't apply to them

Heya. This is question for the admin of this site. What is your observability stack like?

Don't you sometimes question reality? Like why does all this exist? Is God real? Who or what made God? Are our lives all that there is? We die and it's gone? Everyone we ever loved will just be gone one day? Nothing makes sense

I took the 73 Mbps 4K NLUUG Tears of Steel encode, scaled it to 720p, and used CRF 10 veryslow x264 to simulate 720p BD.
SSIM cheating was disabled in AV1 with tune 0 and variance boost, 720p was chosen to handicap AV1's 128x128 superblocks.
Even when nearly maxing out x264 compression , preset 4 AV1 = ~30% better compression and encodes ~40% faster as well.
I confidently declare that H.264 is now official boomer trash like flickering CRT displays.

I believe that the spirit of Anime Movies can be applied IRL in this End Times, at least one RPG game and 5 anime can represent it. These are EarthBound, Dragon Ball, Made in Abyss, Dr. Stone, Full Metal Panic & Evangelion.

I noticed this place supports AV1, hope it's cool if I crosspost from 4chan's /g/ board. I present you a script that targets SSIM, only 1 input video file per folder though.

@echo off & mkdir temp
:loop
set /p crf="CRF? (30-50 reccomended): "
for %%f in (*.mkv, *.mp4, *.mov) do (
    ffmpeg -i "%%f" -c:v libsvtav1 ^
    -crf %crf% -preset 4 -pix_fmt yuv420p10le -svtav1-params ^
    keyint=2s:lookahead=120:tune=0:enable-variance-boost=1:variance-boost-strength=3:variance-octile=4 ^
    -c:a libopus -b:a 64k -y "%%f_CRF-%crf%_AV1.webm"

 

echo: & echo SSIM result:
ffmpeg -hide_banner -loglevel error -i "%%f" -c:v libx264 -pix_fmt yuv420p10le ^
-preset ultrafast -crf 0 -y temp/temp_source_2_10b.mkv
ffmpeg -hide_banner -i "%%f_CRF-%crf%_AV1.webm" -i temp/temp_source_2_10b.mkv ^
-lavfi ssim -f null - 2>&1 | findstr "[Parsed_ssim"
echo:
)
goto loop

1 problem: AV1 cheats in SSIM. It intelligently preserves the structure of video but destroys fine detail. However these disable SSIM cheating:
tune=0 Prioritizes perceptual/visual quality
enable-variance-boost=1 allocates more bits to low-contrast areas (such as skin, clouds, or foggy scenes) that typically suffer from blurring and artifacting in fixed-quantization encoding.
variance-boost-strength=3 Applies medium strength variance boost, enough to improve quality but not bloat bitrate.
variance-octile=4 Applies medium strength for the new 8x8 variance algorithm, which is used for adaptive quantization.

All of these not only give you better/accurate SSIM scores but allow AV1 to create subjectively medium to high quality AV1 encodes, not just compete in objective metric pissing contests.
