Your input is interlaced and you probably want a progressive output.
You did NOT de-interlace.

That makes (when there is motion) it way more complicated, and it will look plain ugly.
Try it with yadif or something else, see if that makes a difference.

Then, you also did not target QT player (-pix_fmt yuv420p IIRC)
