I was hoping for some really good stuff there...didn't find it. Bland. But I'll use it to try and heat up a little debate...
The editor's statement that he does his first cuts without the audio, is laughable (IMHO). Sure, when you have directorial control, whenever possible, the video should carry the film and not rely on narrative. But a film (or video) is a medium that consists of both sound and sight. There is just no escaping that fact - at least not since the days of Charlie Chaplin ended.
By ignoring part of the medium, are your actions really likely to enhance the story as a whole? I don't see how. Now, I'm looking at this from the view of an event videographer, but even in the movies, there are times when the dialog is carrying the story. No getting around it. When Mary says something that will have an emotional impact on Joe, the cut needs to be made. Joe may be expressionless and that may tell us something about how he's handling it, but an editor who isn't listening to the dialog, won't know to make the cut.
A hunter may be better able to detect motion in a camoflauged setting by filtering out colors and seeing in black and white, but an editor who cuts by filtering out the audio portions is a deaf hunter and I know of no situations where ignoring sound would be helpful in hunting or in editing.
