It's also human biology. Anything under 30fps feels dream-like, surreal, fictional. Anything over 30fps feels "real". Films are like dreams. They tap into your subconscious. When you dream, it feels like you are really there, but then you wake up and realize it was just a dream - your reflection in the mirror was blurry, the time on the clock was jumping all over the place every time you looked and you could only run really slowly. Still, you felt fear and happiness and joy and despair. You laughed and you cried. It's the same for cinema.
That's also why 12K, 600fps, HDR, supersharp image is great for sports, nature documentaries, news, porn and stuff like that, but not so much for movies.
I agree . Though I think some early testing showed the transition may be over 40fps. If you want to tell a fictional story then use a slow frame rate and any other image management you want to create an emotional response. If you want to convince viewers its real then use the highest resolution, frame rate and dynamic range you can provide. Yes I know there are lots of documentaries that were shot on film at 24fps or less when that was the only choice of course. For me an event or documentary should try and transport the viewer into the scene as close as possible, as if they were standing next to the camera person. Technology today provides both these options in the same camera so the choice becomes one of what impression do you want to make on the viewer. Is it real or a story.
