Frame Store Operations (Option)
Mask Draw Using Key Channel
Software Version 5.2 and later allows the Mask Draw feature to be
used in a Model 2200 Switcher (the Model 2200 does not have a
Mask Store module available) or in a Model 4000 Switcher which
does not have the Mask Store Option installed.
This mode of operation uses the Key portion of the new Frame
Store module to freeze a mask. After being set up, operation is
controlled by the Frame Store and Mask control panels and the
Frame Store and Mask Store menus.
NOTE:
The new Frame Store module (064814-04 or later) is required
for this mode of operation.
To use the Key Store as a Mask Store:
1. Connect the graphics tablet to the Model 2200 or Model 4000
control panel as described in the previous section.
2. Map the Key Store output to a primary video input using the
Map Inputs Menu.
3. Press the Inhibit Mask or Force Mask button on the desired
keyer panel to delegate the Mask panel to that keyer.
4. Select MASK BUS (on the Mask panel) as the mask source for
keying. (Do not select MASK STORE.)
5. Set up the key on that M/E as desired.
