Analysis of editing techniques used in an opening sequence

As part of our research on opening sequences, we looked at the editing techniques in a film that inspired us and that is in the same sub genre as our own opening sequence, 'Se7en'.


There is long shot duration used at the beginning when we are shown a book and a picture of a hand, which makes the audience wonder what the book is about, and leaves them wondering if this plays a role in the rest of the film. This is also when the production company is introduced. 
It turns into short shot duration when enigmas are shown, for example what looks like a razor blade. This builds up tension and suspense, as the music also speeds up when this happens. 
There are many fade in's and out's throughout the opening sequence which makes it run smoothly. When we see a pen writing on the paper, there are two images shown over each other, one with a higher opacity, which suggests to us the passing of time. 
The cuts in the opening sequence to 'Se7en' are very fast and racy, adding confusion and building the tension. The editing gets even faster near to the end of the opening credits, which is parallel to the music. This keeps the audience on the edge of their seats, and intrigues them to want to know what is going to happen next. It could also add a sense of fear to the audience as what is to come in the rest of the film.
