Hi all! Seems no matter how much Google-Fu I do, I get two complete ends of the "4K editing" spectrum. You've got professionals who are working on feature films, complaining the thing can't handle crazy workflows and super-high bit rate 4K as well as their 24 core desktops. And then on the other side, you have people editing super low bitrate 4K from their GoPro and all is fine. But there are a lot of us DSLR users out there shooting decently high-bitrate 4K with our 5D Mk IVs and the upcoming GH5. Anyone using the new MBP as their primary 4K editing machine? How is it?
