Configure bi-directional device ports as inputs or outputs#
You can configure your device’s bi-directional SDI ports to be used as input or as output ports within the “Devices” tab in Livegrade’s settings (open via main menu Livegrade > [Settings…]) under “AJA Video I/O Configuration.”

Devices settings
A table displays all connected devices in a separate row, and you can choose from a range of configuration presets supported by each device.
Clicking on the “Profile” drop-down allows to select a specific permutation.
When you finish configuring the device ports of your AJA video I/O devices, you need to restart the application to apply your changes.
Associate device ports with input and output slots#
Within the slot manager, you can associate your Blackmagic device’s SDI input ports with an input slot and, in the same way, SDI output ports with outputs:
