Help with green artifacts?

[Forteen88]

I got a video with some green pixels at the wrong places. Here at this frame it's much green pixels around the windows of the house,

Is there a good Avisynth-filter that makes it less green at the wrong places, but still let the grass be green?

Thanks.

That's chromatic aberration (http://en.wikipedia.org/wiki/Chromatic_aberration).

Thanks Didée. I used MergeChroma() as you recommended in this thread,
http://forum.doom9.org/showthread.php?t=135546
but it was still some chroma left (using MergeChroma(aWarpSharp()) ). Although it's much less chroma than before, so I'm pretty satisfied.

EDIT: I used MergeChroma multiple times in rows after one another, and it looked much better (although the encoding-time will be harsh :P).

BTW, I get some yellow color where it should be white (snow) on the mountain (on that screenshot), how do I make it less yellow (but more white)?
