Using the Take Button to Complete a Transition
Using the Take Button to Complete a Transition
A transition is normally initiated by pressing the Pre Roll Take and then the
Take button. The rate of a transition is determined by the four buttons on the
bottom left area of the panel marked Slow, Med, Fast , and Cut . Each rate
button is programmed with a specific duration during configuration, using
the Channel Setup table.
By default, the transition will begin and execute with the same rate on both
video and audio (to vary the timing or rate between video and audio, see
DVE Effects
on page 191 .The transition duration is automatically displayed
in the Rate display above the Take button ( Figure 113 ).
Figure 113. Rate Display
Each transition will cause all information that is contained on the Preset
(PST) bus to be transferred to the Program (PGM) bus, and vice versa.
When a transition occurs, all the Preset audio gains and balances, the key
source and key information such as clips, background, and so forth are all
transferred to the Program bus, not just the Preset source. This transition to
the Program bus allows the next event to be completely previewed and
transferred to the Program bus with a single transition.
Grass Valley recommends that this “Preset -and then-Take” technique
should be used whenever possible; rather than taking a source directly to
Air on the Program bus.
Other Transition Buttons
Aside from the Take button, there are other buttons that can be used for tran-
sitions ( Figure 114 on page 187 ). Each of these buttons is explained below.
The Preroll Take button: The button may be used to que sources before they
are played on air. The duration is defined by the parameter field in the
GPIO Definition table.
The Silent button: This button silences audio outputs. To return to normal
levels, press Silent again.
