    Use 255 instead of 256, to restrict to 8-bits.
    
    Only noise level differences in performance.
    
    AWCY:
                       High Latency     Low Latency
      All Keyframes    -0.01            -0.01
      Video overall    -0.01            -0.07

    hdres             -0.010            -0.022      
    
    Note: By moving from 18-bit to 8-bit and then
    cutting off at 255 (this change, overall effect is
    noise level too (neutral or better).
