I have a client who is wanting to shoot at 50 f.p.s constantly. Now I know that the main purpose for this would be to shoot 'slow-mo', but they are also saying that they only want to use SOME of the footage shot at 50 f.p.s for slow-mo and that they have been told this frame rate will produce a nice look?

It is my understanding that this is incorrect and that slow-mo is the ONLY reason for shooting at that rate.

Can anyone shed some light on this for me please?........................
