Sure, I wondered if there were any non-iframe only encoders out for recording uhd

  Well the 300$ Sony action cam in front of me can shoot 2160p30 @100Mbit/s in good quality, considering the form factor. A nicely clocked Nvidia GPU can also use it's H.265 encoder to record at double that, both bandwidth and framerate. These are I/P frame coders, at least you'd not want to use B-frames at these speeds as more effort in your P frames yields more ROI. Intel should, as part of QuickSync, also offer such acceleration, but I am not sure how much that encoder can handle. I am confident it can do something in UHD with P-frames, but I have no idea how good it feats compared to the Nvidia encoder. If the UHD coding is within it's design range, it should yield higher quality though, albeit at barely enough frame rate. If you try, you can push over 100 fps through the Nvidia one, but quality will suffer even more.
