Proc Amp Controls
Monochrome Video Effect
You can use the proc amp controls to create special effects, such as
the following monochrome effect:
1. On the PGM bus, double press a video [CROSSPOINT] . This will
cause the Proc Amp menu to appear in the menu display.
2. Adjust the (CHROMA SATURATION) soft knob in the Proc Amp
menu to make the on-air video black and white. If you wish,
you can key over this black and white scene with a color
image, or you can do a transition to the same background
video in full color as follows:
3. Press the [CONFIG] top level menu button, and select the [XPT
MAP] soft button from the menu that appears. This will bring
up the Crosspoint Map menu.
4. In the Crosspoint Map menu, assign the video source selected
in step 1 to a second crosspoint. When finished, you should
have the same video source assigned to two different
crosspoints.
5. Select the newly-mapped [CROSSPOINT] on the PST bus.
6. Now do a background mix or wipe between the monochrome
and color versions of the same scene.
