Operating Your ATEM Switcher
Using Upstream Keyer Transitions
In order to help you understand the various ways in which multiple keys can be taken on and off the program
output, we have provided a few examples. In the examples below KEY 1 contains a live bug on the top left
of the screen while KEY 2 contains a bug at the bottom right hand side of the screen.
Example 1:
In this example none of the upstream keyers are currently on-air. The next transition has key 1 selected,
therefore the next transition will change the state of key 1 and turn it ON so that it is visible on the
program output.

Example 2:
In this example, key 1 is currently on air, indicated by the illuminated ON button. The next transition has Key 1
selected, therefore the next transition will change the state of key 1 and turn it OFF so that it is not visible
on the program output.
