3 Manually move the fader bar from one end to the other to execute the transition.
The next fader bar move will begin a new transition.
4 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. On the advanced panel, the
fader bar indicator also displays the position and progress of the transition. On the software
control panel, the virtual fader bar displays the position and progress of the transition.
5 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.
Preview Transition
ATEM switchers have a powerful feature which allows you to review and adjust a transition on
the preview output. The preview transition mode lets you verify a transition before actually
performing it on air.
To preview a transition on the software control panel or ATEM advanced panel:
1 On the preview bus, select the video source that you want on the program output.
2 Select the transition type using the transition type buttons in the transition control block.
3 Press the PREV TRANS button to put the switcher into preview transition mode. ThePREV
TRANS button will illuminate red and the preview output will change so
that it is a copy of the program output.
4 Manually move the fader bar from one end to the other to preview the transition on the
preview output. The program output will remain unchanged.
5 Press the PREV TRANS button to turn off preview transition mode.
