Manual Transitions
Manual transitions let you manually transition between program and preview sources using the
fader bar in the transition control block. Mix, dip, wipe and DVE transitions can all be performed
as a manual transition.
To perform a manual transition
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 Manually move the fader bar or transition slider from one end to the other to execute
the transition. The next move on the fader bar or transition slider 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. The LED indicator
on the fader bar or transition slider also displays the position and progress of
the transition.
TIP You will also see the ATEM software control panel mirror the move on the
hardware panel.
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.
