Split a Key
Split a Key
Sometimes you may wish to use the key cut signal of one source with the key fill or video
signal of another source. For example, you may have a Character Generator creating matte
filled characters, but wish to use a different signal to fill the characters. A split key is used to
accomplish this.
A split key can be created three different ways:
• Configure a source in the Eng Setup/Source Destination menu that uses different video
for cut than for fill. That split key will initially be used whenever that engineering source
is selected. See the K-Frame Installation and Service Manual for more information.
• Setup a key patch (an implicit split key). This split key is used whenever that logical
source is selected, and adds operational flexibility (see Patch a Key Input from Another
Source , on page 48).
• Setup an explicit split key using the Source Ops menu. This split key is used only at the
time is has been set. Selecting a different source, then returning to that formerly split
source removes the split key.
To create an explicit split key:
1 Select Source Ops , MEs .
2 Select an ME button (left).
3 Select the Cut signal data pad for the Keyer you wish to split (highlights blue).
4 Select a source from the scrolling Source List (right) and select that source.
The ME Status display in the Transition area shows the source names of any key cut signals.
Note: On GV Switcher systems, the Source Select buses by default tally the
key fill signal.
