By cutting on the action, you can join the shots without creating a jump. The new shot will carry the action continuously, and the audience will never be wise to the cinematic manipulation. There's another type of action other than physical movement. It's psychological or emotional action. If you have a long-running shot of someone talking, cut to the person listening to show that individual's emotional response to what is being said.
Action can be verbal, too.
As two people are conversing, cut back and forth between them as each person speaks. Other important aspects of editing are pacing and rhythm . When action is intense, your shots should be short and they should be cut frequently. For maximum excitement, the length of the short shots should be varied. When the action is slow, the shots should be longer and cut less frequently.
