Yes, I know it is ugly, but the only filter I know that could
eliminate that is motion-compensated deinterlacing, and you know that
it's a quite complex task to write such a deinterlacer.  Or do you
know any simple kernel filter that does not flicker, and still OK
quality (pp=lb is not OK for me)?  You can to top-fiel all the time,
but then the motion will not be smoth.  What your filter does?  Output
at 60fps, since you can do variable rate in G2?
