Sorry, your recommendation was v60, so:
60Mb/s x 60 x 60 gives 216,000Mb (= 216 Gb) for an hour's recording. That would exceed their max capacity limit of 128Gb.
That would be if the camera were writing to the card at it's full rate continuously. The card needs to be fast enough to support the fastest rate the camera might need to write to it. Given what your manual says, I'd probably make sure I went for a class 10 (10Mbps max) if I was going to shoot at 1080p or below, or a U3 (30Mbps max) if I was going to shoot 4K.
It's a bit tricky to work out how much space videos of different resolutions will take up, as it depends on the encoding they're using and what compression. Is there any info in the manual on that? As a rough guide though, if you're recording 1080p at 60fps I *think* you'd be looking at up to 100GB / hour. Obviously, if you shoot at a lower resolution (e.g. 720P) or framerate (e.g. 30fps) it'd take up correspondingly less space.
