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.”

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 AJA device’s SDI input ports with an input slot and, in the same way, SDI output ports with outputs.

Note: Mixing HD and 4K formats between input and output on AJA video I/O devices is currently not supported.

Release AJA devices for other applications#

Within the “Devices” tab in Livegrade’s settings (open via main menu Livegrade > [Settings…]) you will find the checkbox

Enable AJA video I/O devices

This option is enabled by default, so you can access all AJA video I/O devices that are connected to your computer.

If you need to release all AJA video I/O devices, so that you can access them in another application running on the same computer, uncheck this option.
