Is “LiveKey” working in HD dual link 4:4:4 23.98 Psf?

[Luke Maslen]

Hi Thom,

Your question prompted me to create a detailed technical note named How to use LiveKey for Mac OS X. All DeckLink cards, except for the DeckLink HD model, can perform Internal Key in 4:2:2 mode and this includes the DeckLink HD Pro Dual Link card. However it does not perform Internal Key in 4:4:4 mode as this is not supported in hardware.

Hopefully the new technical note will cover the bulk of questions you might have regarding LiveKey. I’m still refining the technical note at the moment but will make it searchable from our support page when I’ve received feedback from some of our engineers.

Luke,

I was thinking that I might be the first to ask that question, and I certainly didn’t want you to put in extra effort, but thanks for the clarification. It seems 4:4:4 is starting to catch on here in LA a bit. Nobody, except for BMD and Sony seem to give a hoot and we were looking for a way to insert a letterbox matte on our last project.

We just finished our second feature and have another on the books for Sept.

Best,
Thom
