Would like to see an option to enable vMix to use External Reference/Blackburst/Genlock etc or at least trigger the I/O device to use the external Ref/BB/Genlock feature on the hardware. This way video can be properly synced to interface with an Broadcast system working in SDI.

For example

Currently I am using an AJA IO 4K - https://www.aja.com/products/io-4k
There is a REF IN - BNC. And we're Using all BNC I/Os (2 in, 2 out)

When Vmix fires, the AJA control panel says VMix is using the AJA device, and the option to choose genlock source is not enabled. it says its set to Internal.

Is there a way for Vmix to tell an I/O device to use it's external REF as reference instead of internal genlock.

Thank you.
