I've changed the posted function santiag a little bit.

Santiag has now three parameters: type, strh and strv. Type means the anti aliasing type. Possible values are "EEDI3", "NNEDI2" and "NNEDI3". strh is the strength for the horizontal anti aliasing and strv is the strength for the vertical anti aliasing. Default values are: type="nnedi3", strh=1 and strv=1.

Contrary to the first posted function, santiag(strh=0, strv=0) now means no anti aliasing. I've also corected the center shift. With NNEDI3 as type, the center shift now works correct for all possible input clips (YV12, YUY2 and RGB24).

function SantiagMod(clip input, string "type", int "strh", int "strv") {
  type = Default(type, "NNEDI3")
  strh = Default(strh, 1)
  strv = Default(strv, 1)


  strh > 0 ? AntiAliasing(type=type, strength=strh) : NOP()
  strv > 0 ? AntiAliasing(type=type, strength=strv) : NOP()

  function AntiAliasing(clip input, string "type", int "strength") {

      if (type == "EEDI3") {
        EEDI3(dh=True, field=0)
        for (i = 2, strength) {
          EEDI3(dh=False, field=(i + 1) % 2)
      else if (type == "NNEDI2") {
        NNEDI2(dh=True, field=0)
        for (i = 2, strength) {
          NNEDI2(dh=False, field=(i + 1) % 2)
      else {
        NNEDI3(dh=True, field=0)
        for (i = 2, strength) {
          NNEDI3(dh=False, field=(i + 1) % 2)

    Spline36Resize(input.Width(), input.Height(), 0, 0.5, input.Width(), input.Height() * 2)

For me, it looks correct.


santiag(strh=2, strv=0):

santiag(strh=0, strv=2):
