Hello, I'm looking for confirmation that HD Link in its current or future incarnation supports dual stream capture from a Decklink Extreme 3D+, in HD 10 bit YUV, to independent media files.
I thought I'd ask first as I don't have two SDI sources handy.

I'm not shooting 3D, instead I want to hook up two EX3 cameras over SDI and use the PC/Decklink/HD Link as a live recorder. If I TC sync the cameras the TC will carry over in each file I presume.

Thank you.

No, this is not planned. Blackmagic should consider added CineForm encoding to their capture tools, they are licensed to do so.
