Frames Per Second

I've not given much thought as to what frames per second I'm going to use as I have no idea as to how many pictures I will be taking. But I'll probably be aiming for around 12 frames per second, I will attempt a test run at some point with something simplistic just to make clear to myself how it's going to work and how many frames per second I will most likely be using. For now I'm saying 12 because I want to aim for a realistic, smooth running picture that will require small frames to work this way.
