Masking Keys with a Pattern Generator
While the Synergy series does not directly support masking keys with a pattern generator, it is
possible to achieve this effect by using a second keyer. Masking keys in this way allows you to
generate a soft-edged mask using
any shape available in the pattern generator — instead of just a
hard-edged box.
Use the following procedure to mask a key with a pattern generator:
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 over
which the key will appear.
Note All elements of the MASK can be adjusted using the three side scroll
knobs or via the positioner on the panel. For a complete explanation
of the positioner , see the Positioner Group discussion at the end of
this chapter.
Note
This procedure uses both keyers, and refers to them as the first keyer
and the second keyer . However, you can choose either MLE keyer to be
the first keyer, as desired.
