Chapter 5, Configuring Your DigiSuite LE and VTR Settings
q Program Output
Use this list to select the type of program output
you want to use. For example, to use your composite and S-Video
recorders, select
Composite and Y/C (S-Video)
. To use your analog
component recorder, select
Analog Component
. If you have the
optional digital module, your digital video (SDI) output will always be
available.
q Preview Output Source
From this list, select the signal type you
want for the preview output from DigiSuite LE. For most applications,
the preview output should be set to
Program
. Set the preview output to
Preview
only if you’re using a program that’s configured to use the
preview output signal.
q Adjust Timing Click this button to adjust the timing settings for your
system. For details, see “Timing settings for DigiSuite LE without the
digital module” on page 66 or “Timing settings for DigiSuite LE with
the digital module” on page 67 .
q SDI Key Output Mode If you have the optional digital module, use
this list to select the type of digital key output you want:
–
Normal
Outputs the digital key signal as-is. The signal will not be
inverted or compressed (see below).
–
Inverted Inverts the digital key output signal so that transparent
areas of the keyed image become opaque, and opaque areas become
transparent.
–
Compressed
Compresses the digital key output signal so that it
uses the standard range of luminance levels (that is, 16 to 235). This
setting is required for most devices. If areas of your keyed image that
should be opaque are displayed as partially transparent, try turning
the compression feature off.
–
Inverted and Compressed Simultaneously inverts and
compresses the digital key output signal.
Important
Unless your mixer supports key signals having 0 to 255
luminance levels, using a non-compressed digital key output may cause
your video to be displayed erratically.
q
Apply Edge Filtering to Graphics
Select this option to help
eliminate distorted or “ringing” edges in your graphics. These can
result from abrupt changes in brightness at the edges of objects.
Because this option reduces the sharpness of your graphics, you should
select it only when needed. If your graphics have been created using a
program designed for video purposes, such as Inscriber/CG Supreme
or Speed Razor RT, do not select this option.
