Someone should put this in a FAQ somewhere.
With such a high bitrate, it's probably just already using the lowest
possible quantizer all the time. Use vqmin=1 (I believe the default is
2), and the bitrate will get much higher. But you won't see much
increase in quality. But then, if you're encoding for max quality and
you don't care about file size (which it looks like you are), you should
really be using vqscale=2 (or 1, if you /really/ don't care about size)
instead of specifying a target bitrate.
There's other ways to use more bits... I think if you add vme=1 the
bitrate goes up, no idea how much impact that has on quality though.
I've never tried to do what you're doing. Good luck.
