Building and editing panels
Video objects and their properties
Video objects are panel controls that allow operators to control the program video and/or
audio that is played out on the specified playout devices. Specifically, these objects can be
used to fade to down the output program video and/or audio by applying A/B mixing of the
incoming video sources using cut, V-fade, U-fade or arbitrary asymmetric V-fade transitions.

Each Video object that is added to the panel must be assigned to control specific channel(s)
and device(s) using the object’s C
ONTROL properties (see “Configuring an object’s Control
properties” on page 4-31 ).
The following table provides functional descriptions of each of objects within the DSK tab:
Video objects Description
Fade To Black/Silence Adding a F ADE T O B LACK /S ILENCE object to a panel creates a toggle button
that allows operators to fade down the keyers to black output and/or fade
the voice-over audio to silence.
In Production mode, the area under the F ADE label turns red when the
keyer is faded to black.
Since this object produces a button, you must define the behavior and
fade rate using the object’s F
ADE TO B LACK (T RUE /F ALSE ), F ADE TO
S ILENCE (T RUE /F ALSE ) and F ADE R ATE (1 and 999 fields, 0 indicates a cut
transition) properties.
Note: Fading to black/silence is considered to be an emergency measure
since it immediately fades the keyer to and from black, and the voice-overs
to and from silence.
