Original (very old) post...

For those of you that can bear to spend the time, I've found that the following is quite effective against the artefacts of dust on a very noisy source:

Split the source into four copies, shifted like this:

a=last
b=crop(2, 0, -2, 0)
c=crop(0, 2, 0, -2)
d=crop(2, 2 ,-2, -2)

Dust each one separately, and recombine. (For the source in question, which is extremely noisy, I use peachsmoother on the result.)

The most annoying thing about the process is that you can't run multiple copies of dust in one script. I had thought that 2.55's dllname_functionname calling syntax might allow you to get round the problem by duplicating the dust DLL, but I can't get that the work. (See here http://www.avisynth.org/AviSynthPlugins for the calling syntax.)

I've resorted to using a preprocessing script, four dust scripts and a combining script, but usually one of the dust scripts crashes. I doesn't anyone knows of a lightweight program that will duplicate the Vdub direct stream copy (or even ->huffy) but that retries a script if there's a crash?
