The big draw is the 4K capture, which can be expressed in two different ways. Cinema 4K is 4096 x 2160, while Quad HD is 3840 x 2160. Both are substantially more robust than what current DSLRs can crank out. It can, of course, still do 1080p video capture, but it cranks up the bitrate up to 200Mbps. That's well above broadcast quality. It has an HDMI 1.4a connector for outputting full UHD streams and it has a huge optional interface unit that has built in XLR microphone inputs, a power connector and some other cinema-specific features.
