I just want to share an experience with RED ONE and BlackmagicDesign Decklink Extreme 2 cards. Hopefully I'm not the only one, because nobody responds to problems of one...
About one month ago I have replaced old Decklink Extreme with the new (and now the only) version with extra HDMI inputs. There were just occasional one-frame dropouts trying to capture RED SDI output with the old Decklink. Since I'm using it just for video assist, I didn't care too much.
Using new Decklink however, huge problem happened. SDI out from RED was dropping out heavily, 3-5 seconds blackout each 10-30 seconds.
I have replaced the card for another piece - same thing.
I have connected RED SDI thru HDLinkPro to monitor - same thing. Always dropping out.
Then I've connected PhantomHD (set to 720p50 out) to the same Decklink and voila! - it ran like a charm, no single frame dropout.
So I've sent our RED ONE to Red service. It took them 1 week, to do - nothing. I don't know what they did, because nothing changed. Not a single reply, no report. They ignore my emails...
It's really hard to guess if the new Decklink cards are faulty, or if the RED ONE sdi out is not ok.
Using RED with Aja or an SDI monitor - it works.
Using Decklink with any other sdi source - it works.
Can those companies solve the mystery of incompatibility?
