== 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.[http://forum.doom9.org/showpost.php?p=1466159&postcount=352&highlight=daa]


== Requirements ==
* AviSynth 2.5.8 or later
* [[FAQ_different_types_content#How_do_I_recognize_progressive.2C_interlaced.2C_telecined.2C_hybrid_and_blended_content.3F|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) }
