Video coding efficiency for high motion scenes is improved by adaptively disabling a parameter indicating whether texture and motion data is coded for a macroblock. The COD parameter is disabled when the number of macroblocks with substantially all zero motion and texture data is less than a threshold number. This reduces the number of bits required to code an interframe video image in a video sequence with high motion and large changes from frame to frame. The coded block pattern for chrominance is also used to determine how to perform entropy coding for the coded block pattern for luminance. In interframe blocks, if the chrominance blocks are coded, it is likely that the luminance blocks will be coded as well. The coded block pattern for chrominance, therefore, is used to select the appropriate entropy coding table for the coded block pattern for luminance.
