How to integrate H2R Graphics into your Blackmagic ATEM to show graphics to your live audience.
Whether you've got an ATEM Mini, ATEM Mini Extreme ISO or an ATEM Constellation 8K (wow!), you can use H2R Graphics to generate lovely on-screen info your your audience.
We'll assume you are running H2R Graphics on a computer with a HDMI output and go from there.
Start by connecting your laptop or computer running H2R Graphics to your ATEM switcher. Typically this is done by using a HDMI cable from the computer and attaching that to one of the inputs on the ATEM.
You'll want to enable "Extended Desktop" mode on this computer as you will not want to mirror your displays.
Open an output window within H2R Graphics, drag it onto the extended desktop display (you'll see the window appear on your ATEMs multiview. Then make that window fullscreen.

Keep in mind, this will remove black from your graphics too. Try to avoid pure black in any graphics, images or themes.
