I do not know about UM4.6k 3:1 Raw footage !
I use UHD/4K from my GoPro Hero 4, Dji Mavic Pro, Panasonic GH4 and Atomos Ninja Flame !
Got the Davinci Resolve 12.5 Studio full version !
Two R9 390X graphics cards - and a BlackMagic Intensity Pro 4K for preview ! Dell 32" 4K for computer and Dell 27" 4K monitor for preview
Be careful which port you are using with BlackMagic card on the motherboard or your graphics card will go from speed 16x to 8x
My two graphics cards cover all ports on the motherboard so was forced to mount my BlackMagic card an alternative place with a cable to the motherboard !
