Abstract
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.
Requirements
- AviSynth 2.5.8 or later
- Progressive input only
- Supported color formats: YV12
Required Plugins
- nnedi3
- MaskTools2
- RemoveGrain and Repair - part of the RemoveGrain v1.0b package.
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) }
