1. A computer-implemented process for encoding video signals, comprising the steps of:

  • (a) receiving a current video frame;

    (b) selecting a quantization level for the current video frame in accordance with a plurality of mappings, wherein each mapping correlates an activity measure with a bits per frame measure and each mapping corresponds to a quantization level of a plurality of quantization levels; and

    (c) encoding the current video frame in accordance with the selected quantization level.
