Pattern Key Settings
Performing an Upstream Pattern Key
To set up a pattern key on the upstream keyer on ATEM Television Studio HD:
1 The first step is to navigate to the upstream key settings in the LCD menu and set
‘next transition’ to ON. This enables the upstream keyer on the preview output so you
can see the key during the setup stage and ties the key to the next transition so it will
transition to air when the next transition is performed.
2 In the LCD menu upstream key settings, set the key type setting to ‘pattern’.
3 Return to the upstream key menu and scroll down to reveal the pattern setting. Use this
setting to choose the pattern you want for the pattern key.
