Performing an Upstream DVE Key
To set up a DVE 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 DVE.
3 Return to the upstream key menu and scroll down to the fill source setting. Select the
image you want to key as the fill source.
4 To enable the drop shadow or border and adjust their parameters, set ‘enable shadow’
in the light source setting to ON, and set the ‘border’ to ON. Set to OFF if you want to
disable the shadow and border. Adjust the shadow angle and altitude settings to
your preference.

To set up a DVE key on the upstream keyer using the software control panel:

Adjusting the x/y position of the DVE
You can independently adjust the x and y positions of the DVE using the position X and Y
settings, or you can tie X and Y parameters together so adjusting one will automatically adjust
the other. To achieve this, simply enable the ‘tie X and Y’ setting.
This also applies to the size parameters.
