Steady and Smooth is a way to maintain sharp focus & prevent any shakiness in your videos, use both hands and lock your elbows into your body for the best stability, this will also prevent blur in your videos. It also isolates the camera operator's movement. Steady and Smooth makes the shot look controlled, capturing the action without any wobbles. I suggest a Steadycam, it is a camera stabilizer, so it absorbs bumps and shakes, even if the camera is jostled or moves over an uneven surface. Your shots will still appear smooth.
