@AndrewRH
We found a temporary workaround.
I used TouchDesigner software to input fill-key video with Decklink sync group and send it to Unity through Spout(Syphon).

But I think this is not efficient method. we need this feature asap.
thank you.

Did anything ever come of this? We are also looking at using the SDI out for Fill and Key for broadcast...
