Without a proper definition of "peak bit rate", this sentence is meaningless. A bit rate is a quantity of information divided by a time. Since it is discrete, there is no way of doing calculus, and therefore there is no notion of instantaneous bit rate. Thus, without saying the period of time on which the bit rate is computed, it does not mean anything. > Two pass encoding is used for CBR and constrained VBR. No, not for CBR. For CBR, you use all bits allowed, period. Regards, -- Nicolas George
