Zodiak User Manual 111
2.5-M/E and 3-M/E Main Panel
The
Wipe
button selects a wipe as the next transition. Each wipe is pre-
defined using either the complex wipe generators or the Utility buses as the
wipe shape. Wipe pattern selections are made in the Wipe menu (see
Wipe
Menus on page 322 ), which these buttons DPOP to.
The
User Tran
button selects customized user defined transition settings.
Specialized enhancements and combinations of transition effects,
including Mix through Video, FAM (Full Additive Mix) or DPM (Trans-
form Engine) transitions, can be programmed into a user transition. These
buttons DPOP to the User Transitions menu, where the user transitions are
defined. Refer to
M/E Menus on page 294 and Mix Through Video Transition
on page 386 for more information on using a user transition.
Performing Transitions
The
Cut
and
Auto Trans
buttons and the
Transition Lever Arm
are used to perform
main transitions on an M/E. After a transition completes, the background
source selections flip-flop, readying the B (or PST) bus for the next source
selection. The progress of a transition is indicated by the up and down
arrows to the left of the lever arms.
The
Cut
button instantaneously replaces the selected elements with their
new sources or states, regardless of the transition type selected. The button
will light briefly to confirm the operator's action.
The
Auto Trans
button starts an automatic transition of a predetermined rate
(see Transition Rates on page 113 ). The button will light during the transi-
tion. Pressing
Auto Trans
a second time during a transition stops the transi-
tion 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.
The
Transition Lever Arm
is used to manually perform a transition. You can
move the lever in either direction to run a transition due to the flip-flop
architecture of the buses. Moving the lever from one limit to the other per-
forms a complete transition. It is possible to start a transition with the lever,
then stop moving the lever at any point, reverse its direction, and even
return it to the original limit without completing the transition.
Recalling an effect or performing an Auto Trans can leave the lever arm out
of sync with the actual transition. In this state the lever arm is inactive. It
will be necessary to move the lever arm or, if the lever arm is at a limit, run
the effect to regain sync. The up and down arrows to the left of each lever
arm indicate which way to move the lever arm (
Figure 77 on page 109 ) to
complete the transition.
Preset Black
The
Preset Black
button modifies a main transition so that it will go through
black, instead of going directly to the new state. This is an alternate action
button (pressed to turn it either on or off). The
Preset Black
button lights
when it has been selected.
