I long for the days when we will no longer need dithering and have high enough color bit depth to remove banding all together.
Oh, and LaTo, what's this? You posting a script with no "show" parameter!  Nah, it aint necessary but I got used to it. It's simple enough to implement my own source view.

You could do it as string "mygraingen" and use eval in the script. This way, you wouldn't need to add all the possible parameters in gradfun2dbmod. (+ more flexibility if the user wants to use a combination of filters, etc etc) mygraingen="grainfactory3(blabla).something else()"

One way you can do this is to make a helper function.
Code:
function EvalFunction(clip src, string "filter")
{
src
processed = Eval(filter)
return processed
}
Code:
# Without the helper function you have to do this:
Avisource("..")
src = last
proc = src.SomeFiltering()
src
dither = Eval("Blur(1)")
# With the helper function you can do this:
Avisource("...")
src = last
proc = src.SomeFiltering()
dither = src.EvalFunction("Blur(1)")

Wow took me a minute to see the difference without cheating by looking at the bottom, looks fantastic man.
So this filter mainly removes grainy sort of damage? What program did you use to produce that shot for comparing, could save myself a lot of time if you're willing to care and share

I think str parameter should be float (it is float in addgrain).
Otherwise it's really a good script, I tried it on some anime clips and it works very well, a lot better than a simple GradFun2DB. The only problem is that anime shouldn't really have any grain so the default parameters need a little bit of tweaking  (supersampling may help too).
