I'm working on Axymmetry DE Community, with Rtx 3090. NVIDIA and Blackmagic DeckLink 4K Extreme 12G/ with HDMI.No problem for Camera Input with the Blackmagic card ( PANASONIC S1 H Camera on HDMI Blackmagic Input) but i can't send the final composition output signal to the blackmagic trough HDMI. The Blackmagic OUT is connected to an Atomos Ninja V which always shows a black video. The same thing with other monitors both HD and 4K. The Blackmagic card alone and in other software works perfectly. Do You think It's a problem of the Community Edition? or a Bug ? Thanks for your help.
