Keeping MotShiFac equal to UpShiFac in the next upconverted output
field estimates for minimum matching errors (minimum Halo’s).
MotShiFac at value 16 gives the largest natural vector range (twice as
large as with value 0 or 32). Going above the range with

that vector candidates tend to rotate towards the diagonal directions).

For noisy pictures, this register could be set to logic 1 to improve
border processing in the estimator.
