Video Settings Menu
Figure 132. Video Settings Menu
The Video Settings Menu reports the current Karrera system sync reference
and status, allows selection of HD or SD operating mode, and provides
other system functions.
Sync Reference Select
Choosing HD Analog or SD Analog selects which connector the Video Processor
Frame will use for system reference.
CAUTION A tri-level sync reference signal is required for proper HD system operation.
Choosing HD Digital or SD Digital allows selection of an video input source to
for use as system reference. This should only be used temporarily, for trou-
bleshooting or initial system test, because an interruption of that input
signal can cause Karrera system problems.
Matte Limiting
Matte Limiting determines how the matte generators produce colors.
Limits can be imposed to prevent downstream signal problems.
