[MEncoder-users] Deinterlacing produces red and green ghost effects - looks off

[Sebastian]

Hi all,

I got some interlaced PAL material here. I'm trying to deinterlace, but
no matter which filter I use the result looks off when there's high
motion. I'm using mplayer/mencoder CVS-050511-14:33-3.3.5-20050130.
I've uploaded pictures of a guy in a smoking rasing his hand and then
lowering it.

Here the guy raises his hand. The red ghost hands is faster then the
guys hand.

Here the guy lowers his hand. But this time a green ghost hand is slower
then the guys hand.

What's wrong? Can the filters be fixed? Or is it because the first half
of the movie is progressive and the second is interlaced and mplayers
decoder doesn't get it? I read something alike here:

They figured it's the "Chroma Bug" and linked a description.

Thanks
