External keying with decklink cards
Hi All,
I’m currently developing a custom SDI keying application, and after looking for some infos, it looks like the decklink cards could do a great job !
The matter is that, for high availability purpose, I need to do external keying, and cannot use internal keying features of decklink card range. Is the decklink pro the only card offering 2 independant SDI outputs ?
This application uses directshow filters; does the decklink pro present 2 video renderer filters to directshow (in this case I should split my stream, send video on first renderer, and key on the second one), or a single renderer filter (and then internally splits the stream on the 2 outputs ?).Thanks for your answers & hints.
