Never, because that would be dumb.

I thought that human eyes were not able to see the difference with framerate over 25-30 fps? In the case of the Hobbit I think the 48 fps is for 3D.

Until very recently, I thought that 4K meant around 4000 line resolution as we always refer to current resolutions by mentioning the number of lines (720p, 1080p) I simply assumed they also referred to the number of lines and not to 4 times the area in pixel as it is actually the case.

As BananaBonanza said, the issue is that most HD Stations are morons/greedy and bit starve their streams in order to pump out as much as possible while simultaneously using pathetic encoding. Compression is good.

There are three things (possibly more, but three that I can remember) to consider with regards to the classic choice of frame rate.
Cost and weight of film. Human perception and persistence of vision. And movement on film.
They are all related in this context. The choice of 24 frames per second was chosen because it was the lowest frame rate at which enough people did not experience any negative effects of the frame/flicker/strobing film projector. It was optimised this way because of cost and logistics. 30 frames per second would be 25% more expensive and weigh 25% more than 24 fps, something which made both accountants, and film handlers happy. You can go as low as 12-15 fps while still retaining persistence of vision, but it is not going to look good.
The third thing is that cinematography has been sort of limited in what it can do with these 24 fps, for example panning and action scenes have never really looked good unless the panning is done very slowly or extremely fast, the middle ground has been avoided because it has had too many obvious artefacts. A higher frame rate will allow for more types of camera work.
…eh, I think the RED guys can explain better than I do, I recommend this link.
Wow. This is what all my elderly relatives deep in the Appalachians said about HD in 2005 (without the bit about the knickers).aardman":1bn9n4mp said:I predict 4K or ultra HD or whatever else it is called will never catch on.

I know quite a few people who get motion sickness watching video games, ostensibly because of all the camera motion. They can watch action movies. If film makers made more fast camera pans for action flicks I wonder if there would be a lot more people who couldn't watch those movies.

The studios are complaining now about loss due to piracy and DRMing the hell out of their content on blu ray. Do you think they're going to be more enthused when a near perfect reproduction of theatre quality experience is going to spur them on to releasing them on these new uHD formats? I doubt it. They're happiest selling us the worst quality at the most obscene price they can gouge out of us.

That explains why new movies are available in BluRay, and BluRay 3D....
