6 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.
Each transition type has its own independent transition rate allowing you to perform faster
transitions by simply selecting the transition type and pressing the AUTO button. The previously
used transition rate is remembered for that transition type until it is changed.
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.
Stinger and Graphic Wipe are special transitions 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 control block.
On the ATEM 1 M/E Advanced Panel the transition types, for example dip,
mix and wipe, have their own independent selection button.
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.
Program output for a mix transition.
To perform a mix transition on the ATEM 1 M/E Advanced Panel:
1 On the preview bus, select the video source that you want on the program output.
2 Press the MIX button to select the mix transition type. The LCD menu will automatically
display the transition settings.
3 In the transition settings, use the corresponding LCD control knob to adjust the mix
rate. You can also enter a rate duration using the number pad.
4 Perform the transition as an auto transition or manual transition from the transition
control block.
