User's Manual

To perform an auto transition on the software control panel using a keyboard:
1 Ensure that <caps lock> is off.
2 Press the number key on the keyboard corresponding to the video source that you
want on the program output. The source will be selected on preview and the program
output will remain unchanged.
3 Select the transition type using the transition style buttons in the transition
control block.
4 In the transition palette, select the settings tab for the same transition type as the
transition control block.
5 Set the transition rate and adjust any other parameter for the transition as needed.
6 Press the <return> or <enter> key to initiate the transition.
During the transition, the red and green buttons on the program and preview buses both turn
red to indicate that you are in the middle of a transition. The virtual fader bar automatically
follows the progress of the transition and the rate display updates to indicate the number of
frames remaining as the transition progresses.
At the end of the transition, sources selected on the program and preview buses are
exchanged to indicate that the video source that was on preview is now on program and
vice versa.
A production switcher provides multiple methods of transitioning from one shot to another.
Generally, you use a simple cut transition to move from one background source to another.
Mix, dip, wipe and DVE transitions allow you to transition between two background sources
by gradually phasing out one and phasing in another. The logo wipe is a special transition which
will be covered in a later section. Mix, dip, wipe and DVE transitions are performed as an auto
transition or manual transition using the transition fader bar or slider.
Mix Transitions
A mix is a gradual transition from one source to another and is achieved by interpolating
gradually between two sources, effectively overlapping the sources for the duration of the
effect. The length of the transition or length of the overlap can be adjusted by changing
the mix rate.
