Fyi from my testing, the Raspberry Pi 3 doesn't show an image on my ATEM 1 M/E no matter the HDMI config settings, but the Pi 2 works stock. I was able to get the Pi 3 working when I sent the video through an HDMI to SDI converter though. Assuming the HDMI chips Blackmagic is using on their products are a little picky on the signal being just right, and the Pi 3 no longer works without an additional converter. The Pi 3 worked stock with the converter, but I did change the config settings anyway to be as correct as possible. Edit /boot/config.txt and add the following at the end:
hdmi_mode=5
hdmi_pixel_encoding=3
disable_overscan=1
Save and reboot.
Also to fix the screen going black after being unattended if you haven't already, edit /etc/xdg/lxsession/LXDE-pi/autostart and add the following to the bottom:
@xset s off
@xset -dpms
Save and reboot.
