I wonder if this has something to do with the way our brain handles ocular saccades. ( The rapid eye movement we go through when scanning a room, changing the direction of our gaze. More info here: http://en.wikipedia.org/wiki/Saccade http://en.wikipedia.org/wiki/Saccade)
The brain 'cuts out' our conscious vision during these rapid eye movements. just look around the room at several different objects quickly by moving only your eyes. You will discover an almost complete lack of visual information between points A and B. You would expect to see a blur of movement for a fraction of a second while your eye moves to the new target, but your brain edits this out.
It seems at if a cut during a film could be roughly equivalent - I wonder if some of the information directly preceding or following the hard cut gets edited out by your head becasue it perceives it as a visual anomaly or artifact, much the same as during a saccade?
To another point in the article- edits in film aren't (or shouldn't be) used primarily to keep the viewers interest. During a narrative, a cut should is made to bring context or to move the story forward. This was the way editing was first introduced in fact. Cutting for cutting's sake isn't generally considered good editing.
- joeyo 17y agoThis is not a bad theory. However, with visual saccades an efferent copy of the motor command (the desire to move the eyes, the head or the body) is sent to visual areas. This is what allows to world to appear stable even though the eyes, head or body are moving. This is in contrast with passive observation of cuts in a movie, especially when the cuts are not expected or cannot otherwise be predicted. http://en.wikipedia.org/wiki/Efference_copy#von_Helmholtz http://en.wikipedia.org/wiki/Efference_copy#von_Helmholtz
