DoubleTake Option Operation
Note An M/E primary or secondary output re-entered into the same M/E will result
in a downward 1 line shift in the video. Other re-entry combinations may
cause similar timing shifts or feedback.
With this restriction removed, a secondary output can be selected on a
keyer in the same M/E, and the operator can easily mix or wipe within the
key on the re-entered half of the M/E.
If you want to key a lower third over an incoming video and then use an
Internal DPM to position it over the shoulder of a newscaster, you can
perform all of this in a single M/E.
1. Using Split M/E mode, assign Keyer 4 to the Secondary Partition. Select
the incoming video for the over the shoulder on the utility bus for the
Secondary Partition, select the lower third for the over the shoulder as
the source for Key 4.
2. Now on Keyer 1 select the secondary partition as the source and put it
on-air. Note that the video to be used as the over the shoulder has
dropped a line. Now enable the Internal DPM. Use the Internal DPM
controls to position it to be over the shoulder of the newscaster that is
on the background video for the M/E.
In this instance, the line that was lost re-entering the Secondary into the
Primary doesn’t matter since the image is being repositioned and resized
by the Internal DPM. You still have keyers 2 and 3 available for a final lower
third on the whole image and another key left over all on a single M/E.
Split Layered Mode
Lamina™ Video Compositing, or Layered Mode, is a feature that allows the
operator to composite up to four 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 M/E.
This compositing of keys can be done on either or both of the primary and
secondary outputs.
Split Layered mode can be particularly useful. For instance, you can split
M/E 1 and assign keyer 1 to the primary side and the other three keyers to
the secondary side. On Pgm-Pst keyer 4, you can select M/E 1 secondary as
the source for the keyer. You now have the six keys on Pgm-Pst, (M/E 4 –
Key 1, 2 and 3 and M/E 1 – Key 2, 3 and 4 show up on M/E 4 Keyer 4.)
Layering is enabled on an M/E-by-M/E basis in the M/E Mode Menu.
When enabled for the primary output, the A output has black selected as
the background source and the C output acts as the key cut signal for the
keyers selected for the primary output. Similarly, for the secondary output
the B output has black selected as the background source and the D output
