This parameter controls the number of frames the CBR rate controller
will wait before reacting to bitrate changes and compensating for them
to obtain a constant bitrate over an averaging range of frames.

.B rc_averaging_period=<value>
Real CBR is hard to achieve.
Depending on the video material, bitrate can be variable, and hard to predict.
Therefore Xvid uses an averaging period for which it guarantees a given
amount of bits (minus a small variation).
This settings expresses the "number of frames" for which Xvid averages
bitrate and tries to achieve CBR.

This setting allows Xvid to take a certain percentage of bits away from
high bitrate scenes and give them back to the bit reservoir.
