UHD 60 FPS = 12G-sdi.!! The VA and VA4K only support 6G-sdi and so UHD 30P is maximum allowed input resolution framerate.
For 12G-sdi you need to look at the Atomos recorders or other brands.
But if i remember correctly the Alexa and other Arri cams have 6g and Dual link 6G outputs. They don't have a 12G output.
Red Weapon / Dragon does not even output more then HD on it's monitor outputs.
If you want to output 4K from a RED you need an attachement that costs around 6K to have Quadlink output....
I wish that RED had at least 4K hdmi on there body. As the Sony FS7 does. And even the FS7 is just 3G 1080P maximum on it's SDI outputs..
At this moment the only cameras that have 12G-SDI output are the Ursa series.
Aja Cion has 4K hdmi and Quadlink SDI
F5 & F55 have Quadlink SDI.
