Blackmagic output Render Target

Hi,
I’m experimenting with the BM plugin in UE4.
In the BM output options there is a RenderTarget but seems like it’s not working.
I specifed the output configuration and set which render target I want to stream but the stream fails.

Below are screenshots.
I know I’m using a BM card which is not listed in docs but another functionalities works good :slight_smile:
