LAVC MPEG4 codec don't use full bitrate if it is not needed, i.e. if maximum
quality with your settings has been reached. The common advice in this case
is to increase the resolution to gain more quality.
If developers don't think its pointless - they can change LAVC codec so that it
uses P frames instead of (some) B frames, and/or I frames instead of (some)
P frames if bitrate allows. It will largely increase bitrate and slightly improve
quality. Maybe XVID does just that.
(I will certainly be flamed for such suggestion :)
