Blackmagic Forum

Need some help. I'm in the process of putting together a studio for work. My current workflow: record footage (green screen) with camera; create screencast of educational apps/software; post-production in Premiere (MBP Retina); upload to our website. I'd like to streamline this process. I had been using a A/V mixer but output is no HD. Is there a setup solution using BlackMagic Design products? I'm leaning towards ATEM Production Studio 4K but don't know if that is the right choice. Appreciate input.
