ABSTRACT:
A method for video encoding is disclosed. The method generally includes the steps of (A) dividing a plurality of first macroblocks into at least two classes based on a plurality of first statistics, (B) measuring a respective number of bits used to encode the first macroblocks within each of the classes and (C) based on the measuring in step B, determining a quantization level in at least one of a plurality of second macroblocks that have yet to be encoded.
