Hot swap and image flop me like!

Dear Andrew,

Stating the Obvious:

While recording with the nanoFlash, the camera's viewfinder menu's must not be sent out over the HD-SDI or HDMI, or the nanoFlash will record both the video and the menu's.

Yes hadn't thought of that angle. Fortunately in my camera there is a switch in the menu where you would have to deliberately send the menu signal to the HD-SDI port.

I posted the info as someone posted the question and then changed the content of their post as I was writing it. I altered the context of my post figuring that someone else might try the same thing.
