the reason I use virtual dub for one and only one sharpening pass is because I have yet to find a avisynth filter that can beat the quality of MSU smart sharpen for virtualdub. it's unfortunate but when I save the avi I save it as a huffyuv yuy2 file. which unfortunately means a conversion but gets it back to a yuy2 file.
if anyone can find a way to make msu smartsharpen work in avisynth then be my guest
the reason Ive used so many HSV and RGB filtering in Vdub is because again, no one filter completely accomplishes what my source needs to be corrected. the problem here is that the filters alter little aspects but all three are needed to accomplish the right look.
would be interested in seeing some of your shots, especially a comparison from source to finished article as this is important to determine just what the filters have done.
sharpening for me is the biggest issue which is why I am still using MSU.
asharp delivers too much edge enhancement when I get the same detail as MSU
warpsharp sucks
msharpen can get as good as MSU but then I lightened lines of resolution top and bottom of the picture.
limited sharpen interests me but I haven't tried it yet, nor can I find much info on it.
Laserschwert did do a lot on it in another thread which I have y et to look at.
