Many video compression algorithms require decisions to bemade to select between different coding modes. In the caseof H.264, this includes decisions about whether or notmotion compensation is used, and the block size to be usedfor motion compensation. It has been proposed thatconstrained optimization techniques, such as the method ofLagrange multipliers, can be used to trade off between thequality of the compressed video and the bit rate generated. Inthis paper, we show that in many cases of practical interest,very similar results can be achieved with much simpleroptimizations. Mode selection by simply minimizing thedistortion with motion vectors and header informationproduces very similar results to the full constrainedoptimization, while it saves 31% mode selectioncomputational time.
