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():
Code:
#  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

Code:
Lanczosresize(x*2,y*2).Moderatesharpen(1.0).Lanczosresize(x,y)
to more the complicted ways *you* can think of .....

I tried it out and it is no LS-LS2 but does do a nice job and very light on resources.

BTW: If I go past 0.2 I will get similar edge jaggies that I get with LS2-Thresh above 0.5, very strange.

You need to download aWarpsharp and aSharp plugins and load them as well.


Should look like this:

SetMemoryMax(96)

Import("C:\Program Files\AviSynth 2.5\plugins\LimitedSharpen2.avs")



LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\MaskTools.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\WarpSharp.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\asharp.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\aWarpSharp.dll")



LimitedSharpen2( ss_x=1.0, ss_y=1.0,
\ Smode=4, strength=40, radius=2,aSharpS=1,
\ Lmode=1, wide=false, overshoot=1,
\ soft=false, edgemode=0, special=false,
\ exborder=0 )

Trust me, you don't want to put any warpsharp.dll in the autoloading plugins folder. Just to be safe you know

It's a limitation of memory usage. Some buggy filters don't work without a limitation as i read in some threads before. Also you can handle the usage by yourself for whatever reason

I agree - but we're talking about aWarpSharp here, which I never had a problem with when it's autoloaded; it's the non-"a" warpsharp DLLs that cause trouble.

Yep, I should have been a bit more clear..I meant any of the warpsharp.dlls that are out there. I think there are several of which some seem to work and some don't

How about sharing it using http://www.rapidshare.de/en/main.html?

That'd be less awkward than using GMX for this...

np: Radiohead - I Might Be Wrong (Amnesiac)

Thanks for the hint, here is the link... ^^

There should be a sticky with a list of free hosting like ImageShack or RapidShare!
