Key Store
The following features are defaults for Key Store:
• Source Memory is always on.
• Source Memory is provided for each Key Store—Keyer mode and set-
tings for the last use of the Key Store will be recalled.
• Key is black upon reset—If there is not a Key Store loaded, it will not be
placed on-air.
Each full keyer can store two frames of memory; each frame containing
both Keyer Video (fill) and Key (cut), that together create the Key Store.
Each Key Store can save the use of other switcher resources. For example
instead of using an Image Store channel or another keyer, you could store
a station ID or a replay graphic (still) for a sports show in a Key Store and
switch the image within the keyer.
In the Keyer, Key Store menu ( Figure 29 ), each Store has two frames, Frame
Store 1 and Frame Store 2. Each can ‘Grab’, ‘Store’, and ‘Use’ a still image
for a key source. So in addition to Live video, you have up to two fill/cut
images that can be interchanged on any full keyer source.
The fill and cut from Live, and Frame Store 1 and Frame Store 2 pages can
be used in any combination, for example you can use the fill from Keyer
Video Source, Frame Store 1 with the cut from Keyer Cutout Source, Frame
Store 2. You can even use the Live video from the Keyer Video Source and
the cut from Keyer Cutout Source, Frame Store 1.
Each Key Store has Key Store source memory not controlled by the source
memory settings in Suite Prefs.
On power cycle or reboot, Key Stores will have to be reloaded with the
correct video. They default to black keyed with black which will not show
up on a monitor.
Key Store is E-MEMable and keyframeable.
