I believe this was done by PJ for a couple of reasons. 1) Practical, increasing the shutter speed means either increasing the amount of light for scenes, using faster film stock ( or higher ISO on your RED camera ) or some combination of both. 2) This shutter speed was a compromise between the exposure time 180-degree shutter shooting at 24 -vs- 48 fps, and would still retain some of the blur so that 24fps screenings would appear relatively 'normal'
Indeed. I had to laugh though, because first I read it as a sound person would and wondered why you had made that comment here. The camera uses internal fans to cool down the sensor between takes and it is really loud, like a hair dryer. So when you start shooting that often means stopping because of some sound which wasn't obvious over the background noise of the camera cooling itself down. Not cool.
