Wipe Pattern Generators [8]
Two independent wipe pattern generators provide wipe transitions for
the Mix/Effects processor and the PGM/PST/DSK processor. Either
wipe generator can be fed to the routing switcher and output for use as
a mask source.
The standard wipe generators offer 28 patterns. Wipe pattern controls
include aspect ratio, softness, softness symmetry, position, and rotation.
Wipe border controls include width, opacity, and fill source selection.
The optional Advanced Wipe generator provides 65 additional wipe
patterns, plus matrix wipes, pattern multiplication, pattern modulation,
and pattern morphing for the M/E wipes. The Advanced Wipe
generator replaces both of the standard wipe generators, as well as
adding some of the same features to the SuperMatte generator.
Framestores [9]
Two optional 10-bit full bandwidth framestores can be used to freeze
video, key, or mask signals. Each has strobe freeze with variable duty
cycle, and has independent settings for field 1, field 2, or frame freeze
output. The framestores also provide internal test patterns that you can
route anywhere within or outside the 8150.
You can also save and recall framestore images to and from the floppy
disk drive or the optional internal SCSI hard disk drive.
Key Monitor Selector [10]
The Key Monitor selector lets you view the processed key signal of any
of the three keyers. The label above the Key Fill bus row indicates which
processed key signal you are outputting. You can toggle the Key Bus
Delegation button (the green oblong button above the
SHIFT
buttons)
to select the processed key signal of any keyer.
Mix/Effect Processor [11]
The Mix/Effect processor architecture is very flexible. The processing
blocks consist of a mixer, two keyers, and an internal video routing bus.
You can transition keyer priority freely. Mixer transition types include
mix, wipe, non additive mix (NAM), and full additive mix (FAM). The
M/E processor also lets you break out processed key and fill signals,
route them to external devices for further manipulation, and return them
to the M/E processor, before the final compositing.
PGM/PST /DSK Processor [12]
The PGM/PST mixer transition capabilities are identical to the
Mix/Effects processor, except that it has one active keyer instead of two.
