In short, you're saying you want to decrease the contrast ratio of a
video...  I think you can figure out how to do that with MPlayer...

You already said your camcorder maintains consistent brightness levels
(which you dislike) so al doesn't have anything to do.  That said, with
pp=al:f, I'm willing to bet you'll see SOME difference, perhaps not what
you want, however...
