Live keying with Blackmagic card?
I have a shoot coming up which will be on green screen. We’d like to be able to preview what the key will look like live right on set. We’re shooting on the RED and have a Mac Pro with a Blackmagic HD Extreme card (not the current one that does 3D, but pretty new yet). What is the best (and cheapest) way to do this? Is there software we’d need to buy or will AE or Final Cut work? We do not need to record the footage or have the key be perfect live, just give us a good reference and help us make important tweaks to lighting on set. It’s also possible that we’ll be doing a screen replacement on a (mostly) stationary phone and might want to use the live key on a monitor to guide the hand model to press the right buttons.
Thanks in advance for you help!

Yeah, I had severe doubts about AE being able to handle it. Maybe I’ll try posting this in the Final Cut forum unless someone here has any other ideas.

I think you could use either BoinxTV or VeeScope Live for live chroma keying on a Mac. Trials of both are available for testing.

Thanks Walter! I will try these out and see if they work for us.

Rent a Sony/Panasonic Switcher which has a built in Chromakeyer, and then you can feed the background with the Macpro and the front with the Camera HDSDI feed. Then you can preview the output in HDSDI live.

A Tricaster will also do a live key, although it is much more forgiving than Keylight.
