[HELP] Change the Default Sharpening Value of CAS from 0.6 when using stepped resize

The Artifacts are not visible in vapoursynth preview.

okay, that at least throws Vapoursynth problems out and points to encoding settings.

--preset slow  --output-depth 10 --y4m --profile main10 --subme 5 --bframes 10 --rc-lookahead 120 --crf 16.00 --psy-rd 2.00  --psy-rdoq 1.00 --deblock=-3:-3  --no-sao --aq-mode 3 --aq-strength 0.8 --strong-intra-smoothing  --rskip 0 --no-open-gop --no-cutree --ref 6

Disabling soa and lowering the inloop-deblocking that much feels wrong, try using "-nr-intra X00 --nr-inter X00"
If you can share a small sample or your source and your other settings, I can try to reproduce and may be help with the settings.
Different aq modes might help too.
