Anything which doesn't progress the movie should be discarded. The first stage of recording is to run a virgin tape in the record machine fast forward and back. Black the tape for say 30 seconds, rewind for a few seconds and then record your title or or opening shot. Take particular care in creating titles. They can stimulate immediate audience interest.
Poor ones have the opposite effect.
As with camerawork the editor must think in sequences. Usually this means the sequence will follow along the lines mentioned under camerawork, i.e. it starts with a long shot, or two, followed by one or more mid shots and then detailed close-ups. That order is not sacrosanct. You mustn't be predictable and may also wish to stimulate audience curiosity by introducing an air of mystery and suspense. A one-paced movie is likely to become boring.
