When a 24 frame per second movie is telecined for NTSC, is the original playback speed faithfully preserved or is it running the slightest bit slower? It's just that I recently read the wiki entry for 24 fps to NTSC telecine and it said that because it's not 30 fps it's actually 29.97, the film has to be slowed from 24 to 23.976 fps in order for the original framerate to be redistributed across the NTSC framerate. All this time I thought NTSC actually preserved the original framerate! So which is it, 24 or 23.976?
