Greetings. I need to deploy several GH4 cameras for a job that will record endless amounts of content at 4k. I can get by with standard recording to onboard cards at 8 bit but 10 bit 422 out of the HDMI port would make me a hero. Trouble is I realize I know nothing about HDMI and what I can record to. I see cool solutions with nice monitors but just don't need anything that fancy. Ideally the signal will go through a black box or cable and record to basic hard drive. Does something like this exist? Many thanks.
