You can only output SDI when the INPUT is in ‘SINGLE’ or ‘AUTO SELECT’
mode.
SDI Compatibility Mode
Some video devices use a slightly different version of the 12G standard, which can cause
issues with their ability to detect a video signal that is output from an ATOMOS device.
Enabling SDI Compatibility Mode will cause your NINJA V+ to send out a video signal in
the format that these devices expect. Tap the switch to toggle between On and Off.
