180 degree shutter for video.

[Doyle4]

How do i do this please? cant find the option, im currently running 22nd June Build for 5D mkii, or does 180 degree mean shutter speed of 1/48 when filming at 24/25p? in ML menu my lowest shutter closest to 1/48 is 1/46.8, how can i change it to 48?

Thanks in advance.

Think i get it so its all good, 1/46.8 = 1/47 which is 23.976 x2 roughly... makes sense.. i guess people put 1/48 to make it easier.
