q1=MT_Lutspa(BlankClip(width=256, height=256, pixel_type="YV12"), mode="absolute")
q2=q1.TurnRight
return Subtract(MT_Lutxy(q2, q1, yexpr="x y + 128 -"), MT_Adddiff(q2, q1)).levels(125, 1, 127, 0, 255, false).greyscale.converttorgb32
Shows that the two functions are indeed identical.
But in a complex script I have this line:
#mask2=MT_Adddiff(mask2, t)
mask2=MT_Lutxy(mask2, t, yexpr="x y + 128 -")
I get different, but consistent x264 encodings according to which line I use.
Very strange...
