Performing a Split Video
The Split Video function allows you to hold a luminance Key cutter, and assign a new video source to
fill the hole.
Use the following procedure to perform a Split Video:
1. Ensure that your program/preview monitoring is set as needed for the selected MLE.
Refer to the section “ Using the Preview Bus ” on page 4–33 for details.
2. Select an input on the BKGD bus of the MLE. This provides the background over which
the Key will appear.
3. Press
KEY1
in the MLE Transition Group for the same MLE as you set the
Background for. This will assign the Key bus to Key 1 .
4. Select the desired luminance key source (such as a VTR or title camera) on the Key Bus .
5. Press and hold the
SELF KEY
button and select the new fill source on the Key Bus .
6. Release both buttons.
The display shows the luminance Key plus the new “split” fill source.

the Split Video, you press any button on the Key Bus , the split is
released and you must set up the split again.

Tip
The switcher allows you to perform a split video on any DSK. This
function holds the DSK crosspoint’s luminance Key cutter, and assigns
a new video source to fill the hole. To perform a DSK split video, hold
down the desired DSK crosspoint, then press a crosspoint on any bus
except the Preset Bus .
Operating
Tip
Pressing
KEY2
instead of
KEY1
would assign the Key bus to Key 2 .
Note If, after setting up the split, you select another key type, the split is
released and you must set it up again if desired. Pressing
SELF KEY
again does not re-establish the split.
