I don't know how many directors watch what's being shot through a viewfinder. The ones I've seen are sitting in a chair sipping coffee. What they watch are the dailies, which is 24fps. 24fps is not a limitation, it is the way it is
. If 48fps is "more natural", then audiences are not in agreement. Most of the reaction I read about the 48fps Hobbit was negative. "Looks like a video game"
First the talk was about chopping off part of the image to accommodate today's televisions, and now the talk is about fudging the frame rate to accommodate today's televisions. Yikes.
