Sometimes when shooting an action scene, such as a character being punched, then falling against the wall, I like to move the camera, to follow the character, as they fall back fast. Action with a still camera, can be kind of boring. However, when I try to move the camera with the tripod lever, the movements are kind of jerky. That is because in when you turn the lever, there is a bit of a jerk at first. So the movements aren't as loose. Are all tripods like this or can you get one that is very slippery and moves with a lot more loose slick?
