Try asharp(1, 4) or asharp(1, 3)
If you find it too strong, lower the second parameter.

Always denoise before you sharpen. If you don't, the noise will be sharpenend and that's not what we want.

Have you already looked into lremovedust + limitedsharpen? These are currently the best denoiser and detail enhancer IMO.

+1.

I did some test this w-e because I have some blury sources that absolutly need a detail enhancer. I'm crying about the slowness of limitedsharpen but nothign can beat it.

I tried : asharp(1,3) asharp(1,4) asharp(2,4) asharp(2,3) msharpen() and all parameters of limitedsharpen (edgemode, wide, Smode=4, Lmode=1, Lmode=2...). Nothing better than simply use the default parameters and of course each time, denoise before with remove dust.

Any time the winer is :
Code:
LRemoveDust_YV12(17,1)
LimitedSharpen()

Download the latest MaskTools 2.0 alpha : http://manao4.free.fr/

The function is included in the package, Manao included mg262's functions in MaskTools so there's no need to get the LimitedSupport.dll anymore.

Don't forget to apply Soothe:
http://forum.doom9.org/showthread.php?t=99679
Code:
function Soothe(clip sharp, clip orig, int "keep")
{
keep  = default(keep, 24)
keep  = (keep>100) ? 100 : (keep<0) ? 0 : keep
KP    = string(keep)
diff  = yv12lutxy(orig,sharp,"x y - 128 +", U=1,V=1)
diff2 = diff.temporalsoften(1,255,255,32,2)
diff3 = yv12lutxy(diff,diff2,  "x 128 - y 128 - * 0 < x 128 - 100 / "  + KP 
 \                           + " * 128 + x 128 - abs y 128 - abs > x " + KP 
 \                           + " * y 100 " + KP + " - * + 100 / x ? ?",  U=1,V=1)
return( yv12lutxy(orig,diff3,"x y 128 - -",U=2,V=2) )
}
This version might work with MaskTools 2.0 alpha, better check it before using though as Manao changed some syntax a while ago:
Code:
function Soothe(clip sharp, clip orig, int "keep")
{
keep  = default(keep, 24)
keep  = (keep>100) ? 100 : (keep<0) ? 0 : keep
KP    = string(keep)
diff  = mt_lutxy(orig,sharp,"x y - 128 +", U=1,V=1)
diff2 = diff.temporalsoften(1,255,255,32,2)
diff3 = mt_lutxy(diff,diff2,  "x 128 - y 128 - * 0 < x 128 - 100 / "  + KP 
 \                           + " * 128 + x 128 - abs y 128 - abs > x " + KP 
 \                           + " * y 100 " + KP + " - * + 100 / x ? ?",  U=1,V=1)
return( mt_lutxy(orig,diff3,"x y 128 - -",U=2,V=2) )
}
SeeSaw is discussed here: http://forum.doom9.org/showthread.php?t=104701

These are functions (using several filters). If you wish you can load the whole content of my plugin directory in the link below. You will find these functions in the file calld "function.avsi" and the needed dll are also in the rar.
