Using Keys
This section includes detailed instructions for using keys. Prior to proceeding, ensure that you have
read the previous “
Key Functions ” section thoroughly.
Performing a Self Key
A Self Key is one in which the luminance (or brightness) values of the key source itself are used to cut
the hole.
Use the following procedure to perform a self 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 key will appear.
3. On the Key Bus , select the desired luminance key source (such as a title camera or
VTR).
4. In the MLE’s Key 1 or Key 2 group, press
SELF KEY
.
The Self Key Setup Menu is displayed on the display. In the main area, Key Fill and
Key Alpha sources are listed along with the location of the keyer.
