We are starting to use 4k cameras like the GH4 and Sony A7RII. What are the hardware and/or workflow steps for smooth editing of H.264 4k multicam on CS6 or CC? Can a sufficiently powerful PC smoothly edit three streams of camera native 4k multicam, and if so what is the recommended hardware.
If not, is transcoding to an intermediate codec required? Does anyone use a proxy workflow, and if so how complicated is this?
