Life does not happen at 24FPS.
The standard frame rate that was established over a hundred years ago was considered the minimum necessary to fool the mind that it was seeing continuous action. The effect is known as persistence of vision. That we can make sense of 24 frames per second with black frames inserted in between and accept it as something close to real is fine, but adhering to the belief that movies must only be at 24FPS is insane. How does making the movie more realistic diminish its quality?
Siskel & Ebert reviewed a movie demonstration over 20 years ago where a company was proposing a way to run film at 48FPS and they loved it. The film blur that was evident on frames where there was fast motion was gone. They were hoping that it would become a new standard. It didn't even though it used no more film stock. It did, though, need new projectors so that is most likely why it didn't fly.
One of the Hobbit movies was done at 48FPS. I remember seeing reviews where it was berated for not having enough film judder. It was too smooth. Like life.
My current set, the best 46" set Samsung ever made (because they no longer offer the size),came with de-judder and interpolation off. I, then started experimenting with those settings and, at first, didn't like it. Then, I watched the CG animated feature, Captain Harlock, on Netflix. It has sweeping camera moves that had 24FPS judder on steroids.
When I took the de-judder and interpolation up over and over again watching the same scene repeatedly, my conclusion was that I loved the way it looked with both turned all the way up.
Every time I see the intro to a Universal Studios movie with that giant, CGI logo coming in, it's really smooth... like real life.
I'd prefer that movies were way faster than 24FPS so that they are more real. Why the deficiencies of a medium are considered positive when they spend so much money on making them real to hyper-real is beyond me.
It's like promoting that hi-res digital audio should be shunned in favor of CD's. I don't get it.
Make movies with higher frame rates. Until then, I'll upsample the frame rate. 24FPS sucks.
