1. A method for processing video signals included in video frames to determine characteristics of the video frames, comprising the steps of:

  • a) obtaining video signals included in plural video frames;

    b) assigning plural quantization levels to one of said plural video frames;

    c) pre-encoding said one of said plural video frames using said plural quantization levels to obtain plural bit-rates corresponding to each of said plural quantization levels;

    d) determining bit-rates for each of said plural quantization levels resulting from said pre-encoding step;

    e) repeating steps b-d sequentially for plural succeeding video frames; and

    f) encoding a plurality of said plural video frames after determining the bit-rates for each of said plural video frames.
