Suggest a Fast Anti-aliasing Filter

[killervip0]

Aliasing is big problem in my encoding..so anyone can suggest a fast Anti-aliasing Filter. Recently one of my friend told me to use an Anti-aliasing Filter named as daa() but it is too slow ..for example it took 8hrs to encode a only 25min of video(720*480) with low settings.

blur(1) is very fast, it would be an interesting question why Aliasing is a problem from the start, and it seems you're running a very old PC, since daa() should run realtime or faster on any halfway decent PC of this century.
(If you encode with x264 "placebo", or use additional funky filtering, then that's another ballgame...)

You could try getting YADIF (I don't know the syntax for YADIFMod), and do this:
Merge(Yadif(2,0),Yadif(2,1),0.5)

Of course it depends on what "kind" of antialiasing you need.
As this one works wonders for smoothing the edges of game recordings without antialiasing. (Thus higher performance.)

Not to mention that it runs devilishly fast.
