Background Transition Chaining
There are two chains available for Background Chaining in the menu. You
could for example chain backgrounds for ME 1, ME 2, and ME 3 in Chain 1
and for ME 4 and ME 5 in Chain 2 (
Figure 145 ).
Similar to Key Chaining, where the first ME Keyer button pressed on the
Control Panel is the controlling ME for the chain, the first ME Bkgd button
pressed on the Control Panel becomes the primary or “controlling” ME.
This is important for example when you are coupling MEs (backgrounds,
keyers, buses, etc.) for a multiple feed or 3D broadcast, it will be much more
effective to switch the show from the primary ME with the secondary
ME(s) following.
The Primary ME’s Bkgd Transition button in the Transition area (once
pressed) will be high tally while chained Bkgd Transition buttons will flash.
Note The primary ME’s transition type and rate are not copied into the other MEs
with Background Chaining.
To access the Background Chaining menu, touch User Setups , Suite Prefs , Tran-
sition Chaining , Bkgd Chains ( Figure 145 ).
