algorithms defeat the chroma key circuits and will seldom deliver acceptable results.
Performing a Preset Pattern Key
A Preset Pattern key is one in which the hole is cut based on a wipe pattern that you select in the
Pattern Control group. The pattern (which acts just like the alpha signal used with an auto select
key) is filled with video from the Key Bus . Please note the following rules:
• When you press PST PATT , the system automatically selects FLY KEY and, by default,
selects a box wipe. To use a preset pattern key without the Fly Key mode enabled,
simply press FLY KEY .
• If you perform a Preset Pattern key in the MLE’s Key 1 or DSK 1 , the pattern generator
is full-featured but it is shared with the MLE’s Wipe Generator .
~ If you press PST PATT in Key 1 or DSK 1 , you cannot press WIPE in the MLE’s
Transition group.
~ If WIPE is selected in the MLE’s Transition group and you press PST PATT in
Key 1 or DSK 1 , the WIPE button is turned off and DISS is automatically lit.
• If you perform a Preset Pattern key in the MLE’s Key 2 or in DSK 2 , the pattern
generator is not shared , but it is restricted to the first six columns of wipes (minus the
circle). Matrix wipes are not available.
Use the following procedure to perform a Preset Pattern key on an MLE keyer:
1. Ensure that your program/preview monitoring is set as required. 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 that
will appear outside the wipe pattern (assuming KEY INV is off).
3. On the Key Bus , select the desired source that you want to appear inside the wipe
pattern (assuming KEY INV is off).
4. In the MLE’s Key 1 or Key 2 group, press PST PATT .
The Fly Key mode is automatically enabled if an optional Squeeze & Tease 2D or 3D
card is installed, and Squeeze & Tease Menu 1-2 is displayed by default.

Note
This section of the Operation manual explains Preset Pattern keys
without the Fly Key mode ( Squeeze & Tease 2D ) enabled. For
instructions on the Fly Key mode ( Squeeze & Tease 2D ), refer to the
section “ Flying Keys in 2D ” on page 7–51.
