single memory film mode control (double memory or single memory
type); should be set in single memory film mode to ensure that only
original lines are selected as output when UpcShFac is 0 or 32

Bits 3 and 4 are used to control sensitivity to local vector smoothness
(0 = sensitive to unsmoothness, 3 = hardly sensitive to
unsmoothness). Bits 5 to 7 define the maximum contribution of
non-motion compensated pixels to the output
