[edit] Description

Anti-aliasing with contra-sharpening by Didée. daa() works by averaging two independent interpolations, where each interpolation set works between odd-distanced pixels. This on its own provides sufficient amount of blurring. Enough blurring that the script uses a contra-sharpening step to counteract the blurring.[1]


[edit] Requirements

  • AviSynth 2.5.8 or later
  • Progressive input only
  • Supported color formats: YV12

[edit] Required Plugins

Latest versions of the following filters are recommended unless stated otherwise.


[edit] Script

function daa(clip c) {
nn	= c.nnedi3(field=-2)
dbl   	= merge(selecteven(nn),selectodd(nn))
dblD 	= mt_makediff(c,dbl,U=3,V=3)
shrpD 	= mt_makediff(dbl,dbl.removegrain((width(c)>1100) ? 20 : 11),U=3,V=3)
DD 	= shrpD.repair(dblD,13)
return dbl.mt_adddiff(DD,U=3,V=3) }
