Try the latest version. Also I don't pipe 32-bit avs to 64-bit x265. Using avs2yuv_x64 for 64-bit avs+ to 64-bit x265.
Edit:
Avs script
Code:
ffvideosource("4K.sample.mkv")
z_convertformat(width/2, height/2, resample_filter="spline36")
pipe - avs2yuv_x64 + x265
Code:
avs2yuv_x64 -depth 10 1.avs -o - | x265.exe --y4m - --ctu 32 --preset ultrafast -o nul --pools 10 --frame-threads 2 > pipe.txt 2>&1

It's my bad that I wrote "quite slower", I should write just "slower", but I was surprised that the difference is >10%, I expected to be marginal within statistical error (~1%). |
Using the same options and bm5 binary of avs2yuv, the x265 binary I built a week ago (rather than one from last October), a longer chunk of frames as a representative sample, and having moved all the relevant input files and avs2yuv binaries to my SSD rather than running it from a USB 3.0 flash drive:
