Using the Upstream and Downstream Keyers
Upstream and downstream keyers give you a huge amount of control over special effects such
as titles, lower thirds graphics, chroma keying, general overlays and effects, but also lets you
control how to transition them on and off air.
BACKGROUND
The background button, labeled BKGD, lets you tie the program output, before any keyers are
added, to the next transition. This gives you flexibility to transition the upstream keyer on or off
air independently from the downstream keyers.
KEY 1 TIE
The KEY 1 TIE button enables the upstream keyer on the preview output, along with the next
transition effects, and ties it to the main transition control so that the keyer can be taken to air
with the next transition.
When the upstream keyer is tied to the main transition, the transition will happen at the rate
specified in the transition rate setting.
KEY 1 CUT
The KEY 1 CUT button for the upstream keyer is used to cut the upstream keyer on or off air and
indicates whether it is currently on or off air. The button is illuminated if the upstream keyer is
currently on air.
DSK 1 TIE and DSK 2 TIE
In a similar fashion to the KEY 1 TIE button, the DSK 1 and 2 TIE buttons will enable downstream
keyers 1 and 2 on the preview output, along with the next transition effects, and tie them to the
main transition control so that the downstream keyers can be taken to air with the next
transition.
When the downstream keyer is tied to the main transition, the transition will happen at the rate
specified in the transition rate setting.
DSK 1 CUT and DSK 2 CUT
The DSK CUT buttons for downstream keyers 1 and 2 are used to cut the downstream keyers
on or off air and indicates whether they are currently on or off air. The buttons are illuminated if
the DSKs are currently on air.
DSK 1 AUTO and DSK 2 AUTO
The DSK AUTO buttons will mix the downstream keyers on or off air at the rate specified in the
downstream keyer’s rate setting.
Source Select Buttons for Keyers and Macros
The source select row of numbered buttons above the program and preview rows are used to
set sources for the upstream keyer and each of the downstream keyers. You can also use these
buttons to record and run macros.
The source select buttons let you choose sources for keyers, such as the fill and cut source
