Here's what the director told the Wall St. Journal,
For ‘Avatar 2,’ what I’m most interested in is getting theaters to up their light level… And we want to shoot the movie at 48 or maybe even 60 frames a second, and display it at that speed, which will eliminate a lot of the motion artifacts that I think are causing some people problems… People talk about feeling sick or something like that, and I think it’s because the image is strobing. That’s a function of the 24 frame frame rate, which has actually got nothing to do with 3D. It’s just made more apparent because the 3D is otherwise such an enhanced, realistic image, that all of a sudden you’re aware of this funky strobing which you weren’t aware of.I was actually just talking to a friend about movies being shown in theaters at 60 frames per second instead of 24. 60fps is more natural for the eye and brain to take in process, allowing us to see things much more smoothly and fluidly. I honestly think the next step for feature film projection is to abandon 24fps and move it up to 60fps. That's still years away from happening though, if it ever actually happens. If anyone can push the theaters in the direction to make this change though it's James Cameron.
What do you all think?
