Blackmagic Design Decklink Duo for multi-camera live managing
Hi all,
has anyone had any experience using the Declink line of products by BlackMagic Design?
https://www.blackmagicdesign.com/products/decklink/models
I'm particularly interested in the "Duo" model, as it seems to be able to capture up to 4 SDI inputs at the same time.
Would jit.grab handle the independent inputs?
I'm starting to work on a pretty big production, in which I'll have to mix pre-recorded clips, live video and generative video, all mapped on stage, so I'm searching for any solution that would allow me to control all "In the box", without having to use video mixers or switchers for the cameras. (of course, if I can do that in Jitter, that would be great).
Any suggestion or sharing of experience is welcome.
Thank you
I've used the Decklink Mini Recorder extensively, with no problems in Max. I tend to use it via the Black Syphon application, and pass textures into Max rather than capture directly using jit.grab - but this is limited to the Mac platform. I've used up to three of these cards in a single machine, and there is no problem with multiple capture streams. I haven't used the Duo model.
you can output from blackmagic devices on both mac and windows using jit.grab. check the "Blackmagic" tab of the help file for information. it's recommended you work with gl textures for HD resolutions, via jit.grab @output_texture 1 and a valid render context (e.g. jit.world).
Thank you both for the confirmation!
