AVS2YUV to x264

[MysteryX]

I'm trying to pass AVS2YUV to x264 instead of ffmpeg for 10-bit encoding. I had this working before, but somehow it's not cooperating this time.


"cmd" /c " "avs2yuv.exe" "Input.avs" -o - | "x264-10bit.exe" --psy-rd 1:0.05 --preset veryslow --crf 23 -o "Output.mkv" - "

raw [error]: raw input requires a resolution.
x264 [error]: could not open input file `-'
Input.avs: 1920x1080, 60 fps, 13774 frames
error: wrote only 3085668 of 3110400 bytes


What am I doing wrong?

Also, it was suggested that "psy-rd 1:0.05" generally gave better results with x264. Does the 10-bit version of x264 also benefit from this option?

Add --demuxer "y4m" to x264 params and it should work.

Thanks that works :)

If anyone knows about the psy-rd detail, I'd love to hear: keep or discard that option?

Who suggested that? Values in the tunings are higher so the developers seem to think it's useful in most cases. And even higher.
Maybe just use the tunings?
