3 ) U nder-over:
This selection combines the
I n t e r n a l
a n d the
Chroma k e y
stencils so that the stencil is determined to be
O n
only where
both
the internal and the chroma key stencils are
On.
This a l lows a n external video sou rce to be effectively i nserted
right into any still image that may be in the field store. This
gives a three level
multi-plane
effect within the one CVI. This is
one of the most powerful features of the CVI.
N OT E :
As this selection uses the chroma key facility, the
SETUP menu section should be consulted. Since two stencil
sources are combined in
U n der-over,
the INVERT STENCIL
bu tton will invert the
combined
stencil. If you find that you
have drawn the i n ternal stencil in the wrong polarity, i t can
be inverted in isolation by using the
I n v e r t
selection in the
STENCIL WIPES menu.
V I D EO
S O U R C E
This section o f the menu sel ects which o f the two video inputs
will be used in the two main video signal paths of the CVI.
The
Digital path
digitizes video input. Therefore, this path
may be used to colourize, store, pixela te, etc., the live image. The
digital path also includes the
Chroma key-
function, so chroma
keying will be based on the input selected for the
Digital path.
The
Analog path
is the direct, un-modified video pathway from
input to output.
The nu mbers
1
and
2
correspon d to VIDEO INPUTS 1 and 2.
Thus either video input may be d i rected through the
D i g i t a l path
or the
Analog path
or both. If the selections made for the analog
and digital paths are different, then the resultant image can be a
combination of the two video inputs. Some exa mples of this
appear in the PRESETS.
B LAN K I N G
Blanking
applies t o PAL-type versions of the CVI
only.
Choosing
Extended
will blank out a few lines a t the top and
bottom of the screen, to suit some appl ications of the PAL
configuration. Extended bla nking is not a pre-requisite for using
a PAL-type CVI.
Extended
or
Normal
may be selected according
to the aesthetic or technical requirements of the configuration.
The
Blan king
selection is stored with each P RESET.
