The Blackmagic box will not recognize the HDMI signal out of my Canon C100. It will recognize the signal out of both a Sony handicam and the output of a Dell laptop computer. We tested an AJA HDMI to SDI converter with the Canon C100 and it worked fine, so it is not the output of the camera or the HDMI cable itself. Has anyone had the same issue? Any advice? Thanks!
I had this same problem recently. Just go to the black magic website and download the latest firmware for the blackmagic battery converter. Follow the instructions on how to update the converter. With the firmware update, everything works perfectly! I use it reliably on a Steadicam setup.
