I have just recorded a test with my Atomos Ninja which I aquired to use with the Lumix GH2 cameras I have 2 of these. The ninja has a neat little lanc control loop through feature that I hope to use to shoot 3D with paired the GH2 cameras. The control L allows me to sync my HDMI to apple prores recorders. As a side test I plugged my 3d JVC GS TD1 camera into my Ninja in recording into apple prores 422 and it records perfectly.
I am not yet certain if my stream is 3D as I am just getting my new i7 macbook and Finalcut X this next week to test edit my 3D stuff.
anyhow it is looking pretty promising so fa
