Fizick: Yes they can refine different planes at the same time as there are one lock per plane. In a very small speedtest with a 720x576 source and this script
Code:
SetMTmode(2)
function MVDegrain2i(clip "source", int "overlap", int "dct", int "idx")
{
overlap=default(overlap,0) # overlap value (0 to 4 for blksize=8)
dct=default(dct,0) # use dct=1 for clip with light flicker
idx=default(idx,1) # use various idx for different sources in same script
fields=source.SeparateFields() # separate by fields
backward_vec2 = fields.MVAnalyse(isb = true, delta = 2, pel = 2, overlap=overlap, idx = idx,dct=dct)
forward_vec2 = fields.MVAnalyse(isb = false, delta = 2, pel = 2, overlap=overlap, idx = idx,dct=dct)
backward_vec4 = fields.MVAnalyse(isb = true, delta = 4, pel = 2, overlap=overlap, idx = idx,dct=dct)
forward_vec4 = fields.MVAnalyse(isb = false, delta = 4, pel = 2, overlap=overlap, idx = idx,dct=dct)
fields.MVDegrain2(backward_vec2,forward_vec2,backward_vec4,forward_vec4,thSAD=400,idx=idx)
Weave()
}
source=AVISource("F:\20070513-193504.avi").trim(0,101)
mvdegrain2i(source,4,1,1)
the new and old version of mine has the same speed (1.54 fps, 66 sec). I didn't test for artifacts in this run. The weird thing is that without SetMTmode and the above script the speed is 0.74 fps (138 sec) or 2.1(110% speed increase) times faster with 2 cores. I don't know how to explain this. Very strange.
