While this SlashFilm article is dated by April 1st, I hope its content is not a joke. In fact, James Cameron already expressed similar views a year ago. The article digests James Cameron's talk at CinemaCon 2011 in Las Vegas titled "A Demonstration and Exclusive Look at The Future of Cinema".
Cameron believes the time has not yet come for the 4K resolution upgrade as most films are currently authored at 2K (especially in the post production stage where most visual effects are rendered at 1 or 2k).
Rather, the next revolution in cinema will be to begin shooting and projecting films with faster frame rates. The low frame rate results in a strobing effect when their is moderate camera movement. It looks artificial and your brain interoperates it as such. Raising the framerate makes movement look a lot smoother, and gives the impression of an enhanced resolution. It is also one of the major factors of why some people experience discomfort while watching 3D movies.
Cameron talks about 40fps 3D movie: "If watching a 3D movie is like looking through a window, then [with this] we’ve taken the glass out of the window and we’re staring at reality." Cameron isn’t sure what a new standard should be set at — 48fps or 60fps. He mentioned that he will be shooting Avatar 2 at high speeds, either 48 or 60 fps.
The high definition video cameras being used for movies today are able to capture images at high framerates, some reaching as high as 220 fps. The second generation digital projectors (basically any projector bought since January 2010) are able to project at very high framerates. In fact, every 3D presentation we see now is being projected at 140 frames per second, projecting each eye a half dozen times. According to Cameron, theater owners won’t need to buy new expensive equipment, as it will only require software upgrades.
