Interesting mention of the 48fps but it misses out on a lot of the historical details.
15fps was the old standard before 24fps, and it wasn't abandoned due to old hand cranks. It was given up because at 15fps you get odd optical effects like wagon wells moving backwards.
Back in the day a lot of testing was done, and their is plenty of literature on it, and the best frame rate to reduce optical effect and appear as motion is 24fps.
The problem is Computer Geeks have slipped into the Motion Picture filming arena with, and they are marketing 48fps.
For some reason they don't understand
24 Fluid Frames Per Second is what Film is at
Games on the other hand run at
60 Still Frames Per Second
Your eye actually has a very slow frame rate (~15fps for color much higher for gray scale), but it is taking fluid frames, and from them it extrapolates motion. Because games are still and have little or no accurate blur motion you have to do more frames to trick the eye into seeing a blur on the retina that it can interpret as motion.
48fps was marketed as a pipe dream. It was supposed to address the portion of the population that gets motion sick from 3D. If it did that then I might agree with the change. However, the reports of people still getting headaches from the 3D HFR version still exist. They assumed that the issue with the headaches was because of the motion blur, and ignored anything to the contrary. The real issue is with your eyes looking at an image stereoscopically in an unnatural fashion. It causes muscle strain and if your vision is even a little bad it builds up quicker, but even with good vision if you watched something in 3D all day you'd get a headache too.
The next problem is the 48fps is an attempt to get the frames to have less blur. Which makes a fast moving scene clearer, but will also look fake. The reason has nothing to do with the makeup or props. It's because your brain knows that something that is moving is supposed to have a lot of blur. Just move your fingers in front of your eyes if you don't believe me. If it doesn't see the blur it knows the image is fake. Some people say it's just like HD, and in a way they are right, but not for the reasons they think. The reason some people still say HD looks fake is because of foolish CG touch-up on scenes. Each time I see a scene in a film on my HD TV that looks fake it's because the background and the foreground are in focus. Your eyes cant focus on two different planes at the same time and when that happens your brain will know something is fake even if it can't pinpoint the exact issue. SD had an advantage of being just grainy enough that your brain wouldn't notice the background was also in focus with the foreground, and a Theater screen is so big that your eyes dart around enough your brain doesn't realize the image is in complete focus.
