PAL LaserDisc Dot Crawl & Dropout Removal

 (Edited)

I was wondering if anyone has any recommended AviSynth commands to remove/reduce the amount of dot crawl and dropouts (horizontal black flecks) from a PAL LaserDisc capture?

For the droupouts I've tried using the DeScratch() filter and while I could get it to remove them it caused unwanted side effects where it misinterpreted detail lines for dropouts. Here is the command I was using:

TurnLeft().DeScratch(mindif=20,maxgap=30,maxwidth=1,minlen=20,maxlen=60,maxangle=0,blurlen=8,border=0,keep=0).TurnRight()
I have also tried using the DeSpot() filter but this caused the stars to blink on and off *sigh*

For the dot crawl I have tried DeDot() which didn't seem to do anything. I have also tried GuavaComb however this wasn't very effective either. I am currently using the following which helps but is by no means brilliant. :(

RemoveGrain(mode=0,modeU=2,modeV=2).
RemoveGrain(mode=0,modeU=2,modeV=2)
FFT3DFilter(sigma=3,sigma2=3*1.67,sigma3=3*3.3,sigma4=3*6.67,plane=3,bt=3,bw=16,bh=16,ow=8,oh=8,sharpen=0.3,smin=2-,smax=1000,wintype=2,kratio=1,measure=true,interlaced=false,degrid=1)
Any advice / suggestions would be greatly appreciated!

Many Thanks. :)
