Recording HDSDI feed with Blackmagic Decklink

[Steven-Marc C.]

I'm having a hard time trying to record the feed out of the HDSDI port on the Epic through a Blackmagic Decklink HD card.
Has anyone been successful in doing so?
I feel like I've tried every possible setting, both on the camera and the capture settings. All I'm getting is a black screen. The HDSDI output works fine with a monitor.

I had the same problem last week. I do Motion control so I bring a capture system for checking programs. It has a blackmagic decklink studio card and I capture to Premiere on a PC using the motion JPEG codec. The playback tech and all the monitors worked OK. The Epic was set for 24p. I could not capture anything. I tried all the available settings and even reinstalled Decklink. I was capturing fine a few days earlier from a Red One.

Have you had any success solving this problem?

Check for 3G HDSDI and PsF instead of true P. Two real spots people constantly have issues.

[Elliott Balsley]

Michael is right. Also check for 24 vs 23.98. Make sure your capture matches the camera's output.

Sorry, but REDs are strictly progressive, no PsF here. It's part of the specs, and if anybody doesn't support it, it's not RED's fault.

Later today I'll do some tests with our Ultra Studio and tell you what's up.

[Uli Plank]

Ok, I tried, but neither the UltraStudio nor our older DeckLink accepts a 24 (or 25p) signal from the REDs. Very annoying, since true progressive is part of the standard. A Gemini 4:4:4 for example is recognizing and recording such signals just fine, so we need to bug BM for fixing this.

[Stefano Ceccon]

it does not work with the Studio 2
R1mx yes

[RivaiC]

The only way to read the signal is 720p, but thats clearly not ehat u wanted. None of bm product capable of P signal. All psf. U might need aja instead

[Elliott Balsley]

Check your facts. I am running a Scarlet into my Decklink SDI right now and it's working just fine at 1080p23.98. Blackmagic specs show that this is supported: http://www.blackmagicdesign.com/prod...link/techspecs

[Uli Plank]

Well, the specs show 1080p2 and p25 too, but these don't work. 720p50 works, so I don't think it's the unit, cable or user error…

BTW, they neither accept a true progressive signal from a Sony FS100, which is switchable between PsF and progressive (PsF works just fine).
