ME Split Mode Operation
There are also dedicated buttons in the Master E-MEM area ( ME 1 Sec , ME 2
Sec , etc.) which are enabled when the ME is in Split Mode.
• If a Secondary partition is unassigned (none), E-MEM control is only
available on that ME’s individual Local E-MEM area when it has been
delegated to a Secondary partition. The Master E-MEM area will have
no control of that MEs Secondary partition.
• If a Secondary partition is enabled, then E-MEM control of that Sec-
ondary partition will be available from the Master E-MEM area.
Control continues to be available from that ME’s individual Local
E-MEM area when it is delegated to its Secondary partition.
• If a Secondary partition is attached to its Primary partition level,
E-MEM control of the two partitions will be linked together. Specifi-
cally, Master E-MEM operations for that level will always affect both
partitions. When the individual ME is delegated, E-MEM operations
will affect both partitions. However, when the individual ME Sec-
ondary is delegated, E-MEM operation will only affect that Secondary
partition.
Split Layered Mode
Video Compositing, or Layered Mode, is a feature that allows the operator
to composite up to six keys together to create a single video/key pair. These
two signals to be routed in parallel to provide a much cleaner key than
would normally be possible. This key pair can be re-entered into the
switcher on another keyer to create more key layers on a different ME. This
compositing of keys can be done on either or both of the primary and sec-
ondary outputs.
Split Layered mode can be particularly useful. For instance, you can split
ME 1 and assign keyer 1 to the primary side and keyers 2, 3, 4, 5, and 6 to
the secondary side. On Pgm-Pst keyer 6, you can select ME 1 secondary as
the source for the keyer. You now have the six keys on Pgm-Pst, (ME 4 – Key
1, 2, 3, 4, 5, and 6) and ME 1 – Key 2, 3, 4, 5, and 6 show up on ME 4 Keyer 4.)
Layering is enabled on an ME-by-ME basis in the ME Mode menu. When
enabled for the primary output, the A output has black selected as the back-
ground source and the B output acts as the key cut signal for the keyers
selected for the primary output. Similarly, for the secondary output the
C output has black selected as the background source and the D output acts
as the key cut signal for the keyers selected. Priority of the layers is set using
normal keyer priority controls.
Split Layered Mode Menu Controls
The Layered panes are enabled only when the Split button is selected in the
Mode pane ( Figure 149 ). Selecting Split , then selecting the Primary button
