A videoconferencing unit includes first and second encoder that each encodes a video stream of frames and generates variables indicating changes between frames of the video streams. The unit also includes a controller operatively coupled to the first and second encoders. The controller compares the variables from the encoders and determines first and second bit rates for the first and second encoders based on the comparison. Then, the controller sets the first and second encoders to the first and second bit rates, respectively. Preferably, comparing the variables, determining the bit rates, and setting the bit rates are dynamically repeated as the unit operates. In addition, the dynamic repetition is preferably allowed or limited to one or more predetermined intervals of time.
