SSXSharpen in realtime....

Hah, I found an even faster method than this aSharp().aWarpsharp() combo !!!

Try the following:

sharpen(0.2)

W00T!

But seriously. A method to *really* do a minimal version of LS was pointed out by kassandro, uses his RemoveGrain filter set, and was named ModerateSharpen():

#  a function by kassandro.
# (just made "repmode" a parameter / Didée)

function ModerateSharpen(clip input, float amount, int "repmode")
{
	repmode = default(repmode,1)
	sharpened = Sharpen(input, amount)
	return Repair(sharpened, input, mode=repmode)
}

This one should run above realtime without any problems. Practicable "repmode"s are 1 & 2. Maximal "amount" is 1.0, but one should use less, because of the aliasing problem.

I tried it some time ago and for me it's veeeery like an XSharpen without those "dancing" pixels seen in XSharpen used at high values, so it can be a nice candidate for "supersampled" use, from the simplest

Lanczosresize(x*2,y*2).Moderatesharpen(1.0).Lanczosresize(x,y)

to more the complicted ways *you* can think of .....
