The problem is that 24 FPS is now part of the Hollywood "look". 24 FPS is associated with high quality high budget productions in people's minds; 60 FPS looks like a home movie or low-budget TV sitcom. It may take a while to change people's perceptions.

Sitcoms and soap operas look the way they do because of lighting. I won't disagree that 24 fps has something to do with the 'film' look, but I think camera lens, filters, and lighting affect the look of the movie more then the framerate.

Notice he's leaning towards 48p as opposed to 60p, which is an already standardized framerate that your modern TV likely supports. I do not think that is an accident. After all, once we all buy our new 3D TVs, something will have to happen for people to buy new TVs again in 3-4 years. And before you mention bandwidth considerations, I do not have actual data, but I suspect that when using H.264 High Profile, the diff…

48 divides evenly into 240, so in theory a 240Hz TV could take a 48Hz signal and display it without any pulldowns, while 120Hz is 2.5 times 48, so it needs to do some work to create extra frames. (And really, that's the main advantage, currently, of 120Hz and 240Hz: 24, 30, and 60 (the primary American frame rates) all divide evenly into them, unlike 24 into 60).

There are some televisions that have the ability to interpolate a 24fps format and produce an apparent higher frame rate. Watching sports on these televisions is great, but I tried watching Iron Man on one and it made it look like an after school special. I believe this is colloquially know as the 'soap opera effect'. Google for 'samsung soap opera effect'.

My new TV does that - it came with the mode enabled, and when I watched an HD movie off Netflix, it seemed very odd and low-budget - this soap opera effect - until I realized what was going on with a second movie doing the same thing. It's definitely jarring and everything looks, ironically, like it was shot with cheap cameras.

> The filmmaker said that when he begins shooting the "Avatar" sequel in about 18 months, he will be shooting at a higher frame rate, though he has yet to decide if that will be 48 fps or 60 fps. He said George Lucas was "gung-ho" to make the conversion, and also called Peter Jackson one of his allies. Jackson, he said, had at one point been heavily weighing shooting "The Hobbit" at 48 fps. Awesome! It's finally happ…

I'm not a cinematographer but having gone to USC I met and talked with some (both aspiring and those who came back to give guest lectures). There was a digital projection system back in the 80's which had 60fps video, the output was much more 'real' in the sense of looking at the screen seemed more like you were looking at real life, and it jarred folks. One of the directors who was giving a lecture on the future of…

This sounds like an argument similar to the one lamenting the advent of digital photography because the grain of the film no longer provided the same effect in photos. But although the grain effect is available for digital photos, it is seldom seen.

60fps also looks like a high-budget video game. I think that can play a role in overcoming a high-frame-rate aversion.

Perhaps digital animation is the proper place for the transition to take place?

What would be the impact on movie theaters? I am looking at this from the perspective of the simple 2D (non 3D) projection system. I assume if they have a modern digital 2D playback system this may not be a problem. However, what if they have just good ol' projectors that require film reels? Questions on my mind: - Can we roll film at a higher speed on the projector? Can we double the reel intake rate it if we go wit…

I'm not a projectionist, but:

- sound is either on the same reel or on a DTS disc synced to the reel. - I was surprised that a rather small theater in my metro area (no stadium seating, out in the boonies) has digital projectors in all of its screening auditoriums.

For modern movies, I would imagine that in 10 years or less there will be no more acetate prints and all distribution will be digital. For digital prints framerate is solely limited by the response rate of the projector and the throughput available in the playback system.

Hm, I was still stuck into the "above 30 FPS the eye cannot notice the difference" mindset. What's going on?

I would wager that this upper limit, whatever it is, is context-sensitive. Depending on the details of the scene, and the emotional state of the viewer, the eye (and the brain) will notice less or more. (Also, many of today's films use very quick cuts, where a significant clip of an action scene is a mere 10 or so, and viewers are likely adjusting to drinking in a lot of visual information in a short amount of time).

That was never correct. The eye is not a camera, it doesn't work at frames per second.

Humans can notice stuff that hapens in 1/200th of a second.
