Notes on Perfomring Self Keys
Please note the following important points regarding self keys:
• If you select a different self key source, you will need to re-clip the source as outlined
above. There is only
one memory register per MLE keyer for self keys.
• The system allows you to enable the
FLY KEY
button ( Squeeze & Tease mode) for a
Self Key, provided that the other MLE keyer is not flying an Auto Select Key. You can
also fly
two Self Keys in an MLE at a time. Refer to the section “ Flying Keys in 2D ” on
page 7–51 for further details.
Performing an Auto Select Key
An Auto Select (or “linear”) key is one in which two signals are used to cut and fill the hole — a key
(alpha) signal, and a fill signal. These signals originate from devices such as character generators, still
stores, DVEs and graphics systems.
Use the following procedure to perform an auto select key on an MLE Keyer:
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 MLE’s PGM or BKGD bus. This provides the background over
which the auto select key will appear.
3. On the Key Bus , select the desired auto select key source. For example, a character
generator or a DVE.
4. In the MLE’s Key 1 or Key 2 group, press AUTO SELECT to display the Auto Key
Setup Menu .
Auto Key Setup Menu
The menu lists the individual Key Fill and Key Alpha sources (which are linked during
switcher installation), the location of the selected keyer, and whether or not the key’s
alpha signal is shaped (also determined during installation). On the panel, note that the
KEY MEM button turns on automatically to indicate that clip and gain are locked. This
state is also reflected by the “ Locked ” labels on the display.
5. The key’s clip and gain settings were set during the installation process. Typically, they
should not need to be adjusted. If you do need to adjust them temporarily , turn off the
KEY MEM button. The display changes to indicate that clip and gain are now unlocked .
