HOLD INPUT —
this is a keyframable parameter that applies to both the front
and back sides of the picture. It is not part of Source Memory (described in
Section 4 - User Tools), but resides on the Source Memory function timeline
and can be applied to each channel. When
ON
, Source Memory parameters
(including source selections) will not be updated for these keyframes
during the running of the effect. This is useful when selecting sources on-
the-fly. When
OFF
, Source Memory parameters are updated normally.
VIDEO SHAPED —
determines how the key signal will be processed. This is a
source memory parameter that can be applied to the front and back sides
of a picture independently.
SHAPED

be additive.
UNSHAPED
— select when the source video is unshaped. Key processing
will be multiplicative.
SELECT VIDEO SRC
— used to select the source for the Video. When pressed,
the item pointed to by the scroll arrow is hard selected and is displayed in
the Front/Back Side area above, depending on whether Near or Far is
selected on the panel.
