Ops 7–2 • Keying Vision Operator’s Manual (v12.0 MD)
Keyers Module
Keying is the term used to describe when you insert (or electronically cut) portions of one scene
into another, or place titles over background images. Keys are made up of two basic components,
an alpha, that cuts the hole in the background video, and a fill, that fills the hole with different
video.
The number of Keyers you have per MLE depends on the Keyer option you have installed.
Note — The Downstream Keyers Module has the same functionality as the Keyers
Modules, with the addition of two Keyers to support the MultiDSK option.
The following rules and tips apply when working with keys:
• All MLEs have 2 or 4 Keyers that display over top of the Background of that MLE.
• The Keyers of the Downstream Keyer Module, or DSK, display over top of the
Program output of the switcher.
• Each full Keyer can generate a Self Key, Auto Select Key, Preset Pattern Key, or
Chroma Key. The Keyers of the Mix/DSK, half MLE, or MultiDSK keyers, option can
only generate Auto Select Keys and Self Keys.
• The MultiDSK Keyers can only be controlled from the Downstream Keyers Module. If
you assign one of the other panel rows to the PGM/PST MLE, you will not be able to
control the MultiDSK Keyers directly.
The Keyer Module (Figure 7.1) allows you to perform all the Key type, Key modifier, and Key
transitions for the assigned MLE. Each Keyer Module can be broken down into groups of buttons
that perform certain functions, such as selecting the key type, or selecting key parameters for the
active Keyer.
Figure 7.1 Keyers Module (4-Keyer Shown)
The Keyers Module controls all keyers for the MLE. The Keyer that the module is assigned to is
indicated by the lit SEL button. For example, if the SEL button above the 3 is lit, the Keyers
Module is being controlled by Keyer 3. Pressing either SEL button assigns the Keyer Module to
that Keyer.
