This completes the procedure to perform a Preset Pattern key on an MLE keyer.
Please note the following important point regarding Preset Pattern Keys:
• You can fly two Preset Pattern Keys at a time in an MLE (one in Key 1 and one in Key 2)
using the
FLY KEY
button ( Squeeze & Tease mode). You can also fly a Chroma Key or
a Self Key or a Preset Pattern Key. However, you cannot enable the
FLY KEY
button if
the other MLE is already flying an Auto Select Key .
Split Keys
A Split Key is one in which you assign a different fill source for a Key — different than the default
key/fill associations that are set up during installation, and different from those that are set up
automatically for the various Key types. Split keys are typically used for creative montages and for
keying moving video inside Key shapes.
There are two different Split Key functions:
• Split Key — Split Key allows you to hold (retain) the alpha signal of a Key, and assign
a new video source to fill the hole. A typical application is when you fill the alpha signal
from a character generator with the live output from a VTR or camera.
• Split Video — Split Video allows you to hold a (non-alpha) key cutter, and select a new
video source to fill the hole. A typical application is when you fill the luminance Key
signal from your title camera with the live output from a VTR or another MLE.
In both cases, a new fill source is assigned while the hole cutter is held . The following methods allow
you to perform split Keys quickly , and without having to return to the installation menus and change
your Key/fill associations.
Performing a Split Key
The Split Key function allows you to hold the alpha signal of a Key, and assign a new video source to

Use the following procedure to perform a Split Key:
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.
Note
The Split Key function is a temporary assignment. If, after setting up
the Split Key, you press any button on the Key Bus , the split is
released and you must set up the split again.
