A steady editing rhythm of equal length shots maintains the flow of a storyline. This maintains continuity as it is kept steady. If the rhythm is faster, then shorter shots are used which can create tension and suspense because of the pace of the shots. An irregular rhythm can create an element of uncertainty within a scene. Each series of shots, while having its own rhythm, also contributes to the overall pace of a film. Its important not to distract the audience too much or they will lose track of whats going on, so if you maintain the right rhythm and use it correctly only where needed then there will be no distractions. It helps build up to something such an event that is going to take place.
In this video we see a man playing ping pong, and the editing rhythm of this is really really quick. From watching this i felt the sense of competition because of the fast paced editing. It uses a lot of cuts to different shots and different angles, but we understand what they are trying to create through the editing.
