My buddy just picked up a 40 something inch tv with a 120 hertz refresh rate. To celebrate, he watched Black Hawk Down. Later when we were talking about it, he told me that the tv took some "getting used to". He said that Black Hawk Down looked like a BBC documentary, and not like a movie. He went on to say that tv shows like LOST, looked...weird. Good, but strange somehow.
I started thinking about what he said about Black Hawk Down looking like a BBC documentary. If BHD was filmed at 24fps with a 180 degree shutter, we'd be used to watching this on a tv with a 60hertz refresh rate. Now, if we started watching those same movies (and TV shows that are filmed at 24fps like LOST) on a tv that doubles the refresh rate...would the fps be doubled too? Or at least, would you perceive double the frame rate? This would be why he thought BLD looked like a BBC documentary, if the frame rate were doubled to about 48fps this would be quite close to 50fps which is a PAL standard.
Obviously, watching sports or playing video games with a fast refresh rate is preferred. But film, which intentionally bathes itself in motion blur - looks, well, weird.
