Advanced Operations
Partition (Split) an M/E
318
The keyers will be visible in the Primary Partition but are controlled only by the Secondary.
M/E Split Mode from the Control Panel
When an M/E has been split, the Pri and Sec delegation buttons on that M/E are activated.
All M/E stripe resources (E-MEM, Transition, etc.) are delegated to the selected partition.
When both the Pri and Sec buttons are selected, the Primary partition’s state will be
delegated.
Secondary Partition Only
With the Secondary partition delegated (the Sec button selected), a separate set of
background sources from the Primary can be delegated. This can be useful for example if
you want to delegate keyer buses Keyer 1 and Keyer 2 to the Primary partition and Keyer 3
and Keyer 4 buses to the Secondary. Any background buses can be assigned to a partition,
even the same buses; for example the same background in each partition but with different
key sources composited.
M/E Partition Preview
Preview outputs are available for both partitions of a Split M/E. The MxpA output of
each bank is used for the Primary partition preview, and the Mxp2 output is used for
the Secondary partition preview. These preview signals can be mapped to output
connectors with the Output Assignments menu, accessed by selecting Eng Setup, Outputs.
You can preview M/E primary and secondary M/E partitions on switched preview using the
System Bar. Press the Sw PVW button and select an M/E for primary, select the ALT button
(next to Sw PVW) to see the secondary.
Transitions in Split Mode
When the Control Panel controls of a split M/E are delegated to only one partition, the M/E's
main transition system controls only that partition. Moving the Transition Lever Arm or
pressing the Auto Tran or Cut buttons will affect only the delegated partition. Only elements
assigned to that partition may be selected for the next transition. Keyers associated with
the other partition may not be selected and therefore can not be included in the transition.
When a split M/E has been delegated to both partitions, all the controls become functional
and simultaneous transitions in both partitions will occur for what ever elements are
selected.
As an exception to the independence of the two partitions, the
Key Cut and Key Mix buttons
can always be used regardless of partitioning and panel delegation. If a keyer is associated
with the secondary partition, the SEC indicator above the keyer’s cut and mix buttons
illuminates to inform the operator that the keyers are not assigned to the primary partition.
Correcting Split M/E Mode Out of Sync Transition Lever Arm
If a split M/E is delegated to a different partition when a transition is in progress, an out of
sync condition of the transition lever arm will probably result. This situation is similar to
recalling an E-MEM register that splits the screen with a transition wipe. The Transition
