Examples of Operation With Shaped and Unshaped Fill Video
A-11
Incorrect Operation With Unshaped Fill Video
shows what happens when the DPM is set for an
unshaped video output but
SHAPED
is selected in the Map Inputs
menu. The
SHAPED
selection turns off the input Shaping circuit,
so the Unshaped input signal is added directly to the Background
signal (with key hole). This causes excessive luminance where the
fill video and key hole edges overlap, producing a white halo
around the key.
