but I'm one of those people who constantly notices flicker at 24 fps. I'm sorry, but I find that hard to believe - unless you're a cyborg or something. It is known there is a strobing "effect" with 24fps while projection is in 3D though, if that's what you've meant? OTOH, ideal fps for a human eye was shown/concurred long time ago to be at 72-75fps range, and approximate resolution of a 35mm 4-perf to be at 8K-9K range - so that's kind of a mark where we can see things move forward to eventually.

The commenter was probably talking about moving images, not still ones. That is, the strobing effect is due to inadequate temporal resolution, not optical resolution.

I'm sorry, but I find that hard to believe Personally, while I can't see it in movie projection equipment, but 10 years ago when CRTs and stegosaurus roamed the land, I could identify a monitor set to 30Hz refresh at the briefest glance, and could not stand to sit in front of one -- I got headaches from it quickly. That said, I cannot sense the flicker in TVs (presumably their phosphor holds the image longer than a monitor), nor in movie projection.

I consciously try not to notice the 24fps rate, but as I play some 3D computer games I am unfortunately somewhat sensitized to the subject. It's easy enough to see; go to a conventional-film film (I don't think you'll get this effect with digital which is always on), and while something bright is on the screen just wave your arm rapidly in front of you. You'll see visible jerking in the image of your arm, it'll jump all over the place. It shouldn't be that visible to you, you should see the same continuous (and possibly blurry) motion you would see in a darkish room lit by conventional lighting. The film looks the same way and if the film isn't generous with its motion blur it is sometimes quite visible during action scenes or even just moderately fast pans. 24fps needs to die.

  No, you get it with digital as well. They tried it at 30 and people complained that it didn't look "like film", so they put it back to 24. Everything I watch flickers now, to a greater or lesser extent. TV is usually fine but if you're watching a movie or something on a larger screen, pay attention to the corners with your peripheral vision. You don't notice it where you're focusing, but everything around it flickers.

Actually, I saw True Grit in theaters just yesterday, and I noticed a flicker I'm pretty sure was caused by the framerate when there were scenes that contrasted something very bright and very dark. Unlike the other person, though, I actually prefer the lower frame rate because I associate it with film. If it's a higher frame rate, it just doesn't look like a movie to me.
