Hello, Matthias!

meanwhile I found out that pp=fd is causing all this black lines in highmotion
scenes and/or when the camera moves horizontally a little bit faster. In this
case all vertical contoures appear as when I would play interlaced, without

I tried to reduce the image size, but this helped nothing.

Then I chose pp=md again, and this horizontal lines vanished immediately. Also
the CPU load reduced to 70% average.

So I am actually back at my original settings, except that I do not have the
conflicting parameters for vbitrate or vqscale inside any more. I also
stripped a few other arguments which had no effect.

Besides: Which one (vqscale or vbitrate) was actually used all the time?
