I have been asked to write an interface software for television graphics through a system which uses Decklink HD Extreme 3D.
Does setting the external key ensure that both key and fill signals are sent automatically by the card. Or, does my software have to send key and fill as two different signals to the card?
I will have to generate flash files on the run and output these. When I saw my output on an SDI monitor (I haven't got access to a proper mixer yet), I could see the same signal on both the key and fill channels. And because there is no concrete help on this with the product (the Blackmagic support here is only hardware related and they could not help me much on this), I would be grateful if anyone can help me out here.
