Hi, i do my encode with a command line like this

Code:

 vspipe.exe -y script.vpy - | ffmpeg.exe -i - -c:v libx265 -preset veryslow -crf 22 ...

Often my script produce a 16bit output due to scaling or denoising, is it best to dithering the input in vapoursynth, pass the clip undithered as i'm doing or use the parameter --dither of x265 in the command line?
If i should dither it on the script side, what kind of dither is it best for this kind of parameters, if i'm not mistaken ordered dither should be the best when reaching for low bitrate target in every case

Code:

rect=0:amp=0:cutree=0:early-skip=0:limit-refs=3:aq-mode=3:limit-modes=1:level-idc=4:me=2:fast-intra=1:max-merge=3:rd=4:rdoq-level=0:psy-rd=1.1:aq-strength=1.9:deblock=-1,-1

Thanks for the attention
