The present invention provides methods and apparatus for improving video quality in statistical multiplexing (50). For each encoding channel in a statistical multiplexer (50), a respective bit rate need parameter is calculated for encoding (40) of a current frame. in that encoding channel. A video buffering verifier level (VBV, 20) available to each encoding channel is also calculated. detennining whether the VBV Fullness (20) available to each encoding channel is sufficient for encoding the current frame of that channel based on an initial complexity estimate for that current frame. Scale the parameter by an adaptive panic multiplier if the VBV Fullness to be insufficient and …
