[yup]

Hi folk!
After more try and error. tsp, Fizick, Manao, Mug Funky and other i find better way for remove black stripes.
First I use MVTools for prefiltering:

source=AVISource("clip.avi")
fields=source.AssumeBFF().SeparateFields() 
backward_vec = fields.MVAnalyse(isb = true, delta = 2, pel = 2, overlap=4, sharp=2, idx = 1,dct=1)
forward_vec = fields.MVAnalyse(isb = false, delta = 2, pel = 2, overlap=4, sharp=2, idx = 1,dct=1)
fields.MVDegrain1(backward_vec,forward_vec,thSAD=400,idx=1)
Weave()

I use dct=1 for better accuracy motion estimation as recomended Fizick, and save this file in VirtualDub as degr1.avi. After I use ml3dex function from MedianBlur plugin, for estimation motion vector I use prefiltered source and for filtering use source.

AviSource("clip.avi")
AssumeBFF()
ConvertToYV12(interlaced=true)
SeparateFields()
source=last
AviSource("degr1.avi")
AssumeBFF()
ConvertToYV12(interlaced=true)
SeparateFields()
filtered=last
bv1 = filtered.MVAnalyse(blksize=8, isb = true, truemotion=true, delta=2, overlap=4,idx = 1,dct=1)
fv1 = filtered.MVAnalyse(blksize=8, isb = false, truemotion=true, delta=2, overlap=4,idx = 1,dct=1)
bc1 =source.MVFlow(bv1, idx=2, thSCD1=1000) 
fc1 = source.MVFlow(fv1, idx=2, thSCD1=1000) 
interleave(bc1, source, fc1)
ml3dex(mc=false,Y=3, U=3,V=3)
SelectEvery(3,1)
Weave()

Source clip DV YUY2, but ml3dex work only with YV12. For many parts my source enough one pass, but for worst parts I use 2 pass (for second pass I prefiltered pass1 use MVTools). Before encoding, after ml3dex need use MVDegrain1 for remove grain which bring ml3dex. Also I find that use 2 pass 1 step motion estimation (prefiltering MVDegrain1 and ml3dex) work better than use MVDEgrain2 for prefiltering and 2 call ml3dex in script.
See one field for comparing (top filtered, bottom source):

If any have idea for improvement please advice.
With kind regards yup.
