Transition Control
Main Transition Subpanel
The transition controls are used to select the signal elements that will be
involved in the transition (background or keys), define the type of transi-
tion, and perform the transition.
Second Transition Subpanel
These transition controls allow the operator to cut or mix the separate
keyers with individual transition times. The
Cut
and
Auto
buttons at the
bottom or used to cut or auto trans Fade to Black.
This Fade to Black function can be enabled with the FTB Enable button in the
Main Transition Subpanel.
Note In a later software version the Fade to Black , Cut , and Auto buttons as well
as most buttons of the Main Transition S ubpanel will be user-programmable.
Transition Elements
The Key 1 – 4 and BGD buttons select the elements that will change during the
next transition. Pressing these buttons does not change the current output
of the switcher, but prepares for a change (the next transition).
Pressing one transition element button automatically turns off the others in
this group. More than one transition element can be selected by holding
down one button while pressing another in the group. Elements not
selected remain in their current state when the transition is performed. For
example, if Key 1 is on and is not selected as part of the next transition, it will
remain on during and after the transition.
The BGD button selects a change in the background buses. The result will be
a transition from the current source on the PGM bus to the source selected
on the PST bus. After the transition, the buses will flip flop, so the PGM bus
always remains the on-air bus. The PGM bus selection remains the back-
ground source if this button is not selected as part of the next transition.
The
Key 1-4
buttons selects the keyers that will be involved in the next tran-
sition. The keys currently visible on the output of the switcher are identi-
fied by the On indicator lights below each button. Note that a key may be on
but not visible (for example, half way through a preset black transition).
The Prior Trans button selects a change in the key priority. The layering order
(stack) of the keys will transition from the current stack to a new stack spec-
ified by the operator. The new key priority stack is defined using the Keyers
subpanel or via a menu.
