A window is a means of masking off an area of the FG image so that the BG scene is forced ON in that
area of the composite image. It is primarily used in situations where the backing is not large enough to fill
the entire frame. So long as the backing surrounds the FG subject, a window can be used to insert the
BG scene beyond the edges of the backing.
The Ultimatte-9 can use internally generated rectangular windows with variable edge softness, or an
external signal connected to Matte In as an external window signal. An external window signal will force
ON the BG wherever the window signal is white. The Matte In circuitry is fully linear, and will mix the BG
with the processed FG whenever the external window signal is gray. The Matte In circuitry can invert the
polarity of the incoming signal if it does not have the proper polarity (white wherever the BG needs to be
forced ON).
The internally generated windows in the Ultimatte-9 can be inverted so that they mask off an area within
the frame rather than a border of the frame.
The default setting for each edge is a hard edge window. Advancing the control gradually softens each
edge individually
.
Softening the edge of a window can help blend the masked off area with the rest of the
image in a composite.
