Some important things to think about with editing are:
Pairing - alternating one set of shots with another
The Editing Speed - how fast do they cut between scenes? Fast editing involves fast cutting (i.e. shots that are 1-2 seconds long). Fast editing generates excitement and anticipation. Slow editing (i.e. shots are 3 to 10 seconds long) has the opposite effect, and is often in love scenes.
Here are some examples of pairing in films
This is pairing, as the shots alternate from one to the other
The shot speed is fast as they are in an angry fight
The angles used can be used to suggest inferiority or superiority
A sequence of shots in which there is an alternation between two different locations. This sequence builds to a climax and ends with the two things coming together.
This is pairing
The shot speed is increasingly fast
The shots of the character are alternated with shots of what he sees. The first shot identifies who the character is, and the second is what he sees.
Here are some examples of other editing tricks.
The editing together of a large number of shots. Used to compress time. They are generally linked by a unifying piece of sound.
A slightly blurred shot to make the subject seem more attractive, romantic, nostalgic or dreamlike.
Director wants to create a sense of anxiety or confusion, exploiting the unsteady movement of the character. A hand-held shot in which a character is approached from behind usually suggests that someone is being followed.
