Key 1
and
Key 2
Use the
Key 1
and
Key 2
buttons to select the keyers that will be involved
in the next transition. The Background bus selection remains
unchanged if one of these buttons is selected for the next transition.
Note A keyer may be on, but not visible (for example, half way through a preset
black transition).
Key 1 and Key 2
Cut
An instantaneous switch from one picture to another. Switching cir-
cuitry allows cuts only during the vertical interval of the video signal
to prevent disruption of the picture.
Mix
A transition between two video signals in which one signal is faded
down as the other is faded up.
Also called a dissolve (blending a new video into the existing image).
When applying an effect, it gradually blends in the effect.
CUT
Instantaneously replaces the selected elements with their new sources or
states, regardless of the transition type selected.
AUTO
Starts an automatic transition of a predetermined rate, either from one
video to another or when applying an effect. The duration can be set in the
DURATION submenu (see page 82).
Pressing
Auto
a second time during a transition pauses the transition at that
point. The transition can then be completed by pressing the button a third
time or by moving the
Transition Lever Arm
to its opposite limit.
FTB (Fade to Black)
This button fades the video out to or in from a black screen. Audio signals
fade out to or in from silence.
FX
Activates the selected effects for each layer and makes them usable for
transitions. The effects are selected and adjusted in the
TRANSITION
main
menu.
If the
FX
button is deactivated, the selected effects are ignored and Mix is
used for transitions.
See Transition Main Menu on page 77 for information on selecting effects.
