NTSC has 3:2 pulldown and the whole thing of not being a whole number of frames per second.
It's easy to take a PAL video source and convert it to 24fps - the frames just play back 4% slower, no pulldown or interpolation necessary.
It really doesn't matter, because the final 24fps version is going to be synched to the existing soundtrack preservations.
I dunno. I just feel like stretching anything will introduce artifacts. I know it does with sound.
