In Conversation with Walter Murch


Kiran Ganti (KG): What is the definition and the characteristic of a transition?


Walter Murch (WM): At the basic level, a transition is simply the process of changing from some state A to another state, B. What we should examine carefully is the degree of change, and our awareness of it. Change is happening all the time, though we are not always conscious of it. But without change there is no perception. This is somewhat of a paradox. If you are staring constantly at a static object you would think that nothing is changing, but it turns out your eyeballs are constantly moving, though the movements are so tiny you are unaware of it. You might be stationary, the object you are staring at might be stationary, but your eyeballs are rapidly scanning the image in what are called microsaccades, at the rate of around sixty per second. It is this slight vibration the eyeballs are moving about 1/180th of a degree – that is keeping your perception alive, scrubbing the image across a slightly different set of rods and cones at the back of your eye. In a way it is kind of like the scanning electron gun in a video monitor. Fascinating experiments have been performed, neutralizing these microsaccades, and the result is that the vision of the subject quickly dims and then disappears entirely, even though his eyes are open and he is in a lighted room. At a very basic perceptual level, then, there has to be some kind of a transition, a change, for us to perceive the world at all.


1. In film terms, the smallest transition is the frame: this is the equivalent of the microsaccade that keeps vision alive, and we are unconscious of the shift as such from one frame to the next, though it is perceived by us as motion.


2. The next smallest transition is the cut between shots: this is the equivalent of a shift of attention of our eyes and we are intermittently conscious of this sometimes more sometimes less, depending on the nature of the cut.


3. And then a still bigger transition is the cut (or dissolve, or whatever) between one scene and another, and we are usually quite conscious of this. In fact it is the editors job to make sure that the audience is conscious of the transition from one scene to the next, otherwise there will be confusion.


4. Beyond that there are the major transitions between the Acts of a movie, but these are more difficult to qualify since cinema is unlike theatre: very rarely does a curtain fall in a movie! But we do occasionally get a sense of this end of act transition. For example, in The Godfather all the scene transitions up until Michael kills Solozzo and McCluskey have some action or story continuity. But after the double murder we get a somewhat abstract montage of various newspaper images, and the music changes from dramatic orchestral to tinkling piano, and it is by these means that the film is letting us know this is the end of Act I. Everything after these murders will be different.
