Next Transition
The BKGD, KEY 1, KEY 2, KEY 3, KEY 4 buttons are used to select the elements which will
transition on air or off air with the next transition. The number of available keyers depends on
your switcher model. All keys can be faded on and off when the main transition occurs, or you
can select just keys to transition individually, so the main transition control can be used to fade
keys on and off.
When selecting the elements of the next transition, the switcher operator should look at the
preview video output because it provides an accurate representation of what the program
output will look like after the transition is completed. When only the BKGD button is selected, a
transition from the current source on the program bus to the source selected on the preview
bus will occur without any keyers. You can also select only keyers to transition, leaving the
current background live throughout the transition.
ON AIR
The ON AIR indicator buttons indicate which of the keys are currently on air and can also be
used to immediately cut a key on or off air.
Downstream Keyers
TIE
The TIE button will enable the DSK on the preview output, along with the next transition effects,
and tie it to the main transition control so that the DSK can be taken to air with the next
transition.
The DSK will transition at the rate specified in the RATE display of the transition control block. If
the DSK is tied, the signal routing to the clean feed 1 is unaffected.
ON AIR
The ON AIR button is used to cut the DSK on or off air and indicates whether the DSK
is currently on or off air. The button is illuminated if the DSK is currently on air.
AUTO
The AUTO button will mix the DSK on or off air at the rate specified in the DSK RATE window.
This is similar to the main AUTO rate on the transition control block, however it's limited only to
the specific downstream keyer. This can be used to fade up and down bugs and logos, such as
live or replay bugs during production, without interfering with the main program production
transitions.
Fade to Black (FTB)
The FTB button will fade the whole program video output to black at the rate specified in the
fade to black RATE window. Once the program output has been faded to black, the FTB button
will flash red until it is pressed again. Doing so will fade up from black at the same rate, or you
can enter a new rate in the Fade to Black palette in the Switcher window. Fade to black is
mostly used at the start of your production, and at the end of your production, or when cutting
to commercial breaks. It ensures all layers in the switcher are faded down together. A fade to
black cannot be previewed. You can also set the audio mixer to fade the audio with your fade to
black by selecting the AFV button on the master audio output fader.
