Editing Analyze

This trailer is from a Korean drama, that the main character is a police woman that she uses her extraordinary hearing ability to track down the criminal. At the beginning, there is a extreme long shoot  of  people across the street to show that the criminal is a among these people. Then she communicate her partner (the police man) to tell him that she heard the sound of finger playing the lighter, which is the characteristic of the criminal. At this point, the extreme close shoot is shooting at the hand with the lighter turning on and off, and then gave a quick medium long shoot to the police man, showing that he is now aware of the criminal. The background piano music is emphasizing the nervousness of the scene, and sort of telling the audience that the catch is about to happen.
