Auto Transitions
An auto transition allows you to automatically transition between program and preview sources at a
predetermined rate. Any upstream keys that were selected in the next transition and any downstream keys
that were tied to the transition control will also change state. Auto transitions are performed using the auto
button in the transition control block. Mix, dip, wipe, DVE and stinger transitions can all be performed as an
AUTO transition.
To perform an auto transition on the software control panel
Step 1.
On the preview bus, select the video source that you want on the program output.
Step 2.
Select the transition type using the TRANSITION STYLE buttons in the transition control block.
Step 3.
In the transition palette, select the settings tab for the same transition type as the transition control
block.
Step 4.
Set the transition rate and adjust any other parameter for the transition as needed.
Step 5.
Press the AUTO button in the transition control block to initiate the transition.
Step 6.
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.
Step 7.
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.

program output. The source will be selected on preview and the program output will remain
unchanged.
