Hi everyone, I've recorded a touring car race from Brazil on a local TV station. Unfortunately the station appears to have used poor frame rate conversion methods. At the bottom left and right of the image, there is a great deal of the artifacting when any camera pans as the below images demonstrate:

I can crop to remove this but as it can grow quite large this results in a large area of the visible picture being lost. The above is a relatively mild example of the problem.
Can anyone advise on an approach in avisynth to minimise this, or a filter I should be considering?
My thinking is that a strong blurring effect on those corners would do the trick, but I'm unsure on the best way to do this.
