A filter like dust for avisynth 2.52
 

I know you can use dust in avisynth 2.52 by using these lines,

ConvertToYuY2
PixieDust()
ConvertToYV12

but it just too slow and once in a while my computer freezes. I need it because there is no optimal script for non clean sources on 2.52, but one for 2.08 and I just don't like converting back and forth on avisynth. I just need a filter that’s just as good as PixieDust and is faster, so I can encode my TV captures. I know that dust might be coming out with a newer filter, but I have been waiting too long.

Thanx in advance
