Does anyone know the answer to this question?
I keep hearing about people getting headaches from 30 FPS in games, but nobody complains about getting headaches at a 24 FPS movie. Why is that? |
Well, you'll get a headache if those 30 or 24 frames were just thrown out there at that speed, but that isn't what's happening. Rather, a single image is displayed several times making sure that you don't get a "flickery" effect. For 3D though, if you can only display @60 hz, those are divided between your eyes and you'll actually notice that flickering.

I was actually talking about movie theaters where it is 24 frames per second. Not video signals where 24 fps has been converted to 60 fps.
If lower fps can cause headaches, then 24 fps (or watching a movie at a theater should cause more headaches then a 30 fps video picture.

The light in a projector is always on as far as I know, so it shouldn't have the problems of for example a CRT monitor which only lights up each pixel every so often.
It's the same reason why LCDs don't need high refresh rates to make a stable picture, whereas with PC CRTs you needed at least 75 Hz to make it non-flickery enough. LCDs have a backlight, projectors have a front light.
