Motion Threshold
Motion Threshold adjusts the threshold of difference from spatially- and temporally-related pixels,
which are judged to be "motion." If you enter a higher value, the number of pixels in motion will be
greatly reduced. If you enter a lower value, the number of motion pixels greatly increases until the
entire screen, more or less, is considered in motion. The recommended default is 16.
Sharp and Smooth Motion
When the Sharp Motion radio button is selected, detail in motion areas will be sharper, but at the
expense of somewhat jagged diagonal edges.
When the Smooth Motion radio button is selected, more loss of detail will occur in motion areas,
but edges will be smoother.
Since the eye does not clearly see detail in areas of motion – and edge artifacts are highly intrusive –
the Smooth algorithm is preferred for most applications. The Smooth algorithm uses a bit more
CPU.
Both algorithms treat still areas in the same fashion, and there should be no loss of detail in still
areas.
