The frame rate just stuck to an old standard, but it's handy to have because of the demands of higher framerates. Even going to 30 is going to increase bitrate, file size and computational demands by 25%.
We weren't talking about _higher_ frame rates, but rather _native_ frame rates.
Shows shot on film are at 24fps. Almost all current displays and all current broadcasts via OTA, cable, satellite, etc... are all at 30fps or 60fps. This makes it impossible to watch these shows or movies at their native framerate. Motion appears more jerky and less convincing. This compounds the problem of 24fps being so close to threshold of perceivable individual images.
When people say that they see jerky motion (judder) while watching 24fps movies, part of what they are experiencing is also non-native frame rate. Half of the frames are displayed longer than intended while the other half of frames are displayed shorter than intended. When movies are converted to PAL, there are different trade-offs. If playback is sped up by 4%, then all frames can be displayed for the same amount of time. Make the 24fps into 25fps and it fits nicely into 50hz. The same isn't possible when going from 24fps to the 60hz like is needed in America (and other NTSC based countries).
HD resolution is likely be high enough, for most people, for the foreseeable future. Further increases will have diminishing returns in terms of perceived improvement in quality. Perhaps the public will latch onto more complex metrics kind of like how "the megahertz myth" is finally being understood by more and more of the masses. For video, this will mean that people will start caring less about resolution and more about things like bit-rate and native frame rate. In my opinion, the HD specs should have at least included a classification system for bit-rate. All 720p or 1080i weren't created equal. ;-)
Can anyone report if apple is using 24fps encoding for any TV shows?
