As I understand it, 24 fps really means 23.976 fps... more or less.
The differential is an NTSC thing. Final Cut Pro will allow you to create a sequence with a 24 fps time base, which will allow you to edit "true 24fps." Trouble is sound recording standards came from NTSC-land too and a true 24fps time base is not in perfect sync with sound recorded at 48 kHz and will drift after a while. I suppose this means changing the time base of the sound to prevent the drift. Of course, a 23.976 time base makes it easier to transfer to broadcast formats and a film conversion from 23.976 is pretty straightforward too.
Please, if anyone has the patience, correct my little summary.
What about folks preparing material for the web? Should we edit at a 23.976 fps time base? The appeal of a "clean" 24 is strong, though, maybe, ultimately, silly and more trouble than it's worth.
Finally, I just shot with an HVX200 using the 24pN setting. FCP took it in and the frame rate reads 23.976. That suggests, to me, that there is no "true 24p" setting on that camera and I would have to render it on a 24 fps time base if I wanted to cut at exactly that rate.
Am I right that the HVX200 does not shoot at exactly 24 fps at any setting? Is that Varicam and Cine Alta land only?
Thanks for any guidance.
