1. A method, comprising:

  • determining total available bits for a group of pictures;

    estimating a difference in motion between a current frame and a preceding frame before the current frame in the group of pictures;

    determining a difference in residue between the current frame and the preceding frame;

    approximating, based on at least one of the difference in motion or the difference in residue, by successive convex approximation, distortion of the current frame relative to the preceding frame; and

    determining a bit allocation for the current frame based on the approximating the at least one of the difference in motion or the difference in residue.
