Comment (by cehoyos):

 I can reproduce the banding with out.mpg.png but not with out.mpg.
 How did you produce the png? Could you compare with:
 $ ffmpeg -i out.mpg out%2d.png
 or, since there may be quality loss when encoding from yuv420p (mpg) to
 rgb (png):
 $ ffmpeg -i out.mpg -qscale 2 out%2d.jpg
