It all depends how it was transferred to video.

If it was done on a real telecine, the speed would be 23.976 fps, not
24 fps (unless it was shot at 18fps, but that's another ballgame
entirely). If it was transferred frame by frame but being used as
NTSC video, the audio still will need to be "pulled down" 1/10 of
1%. If it was done on a 5-bladed projector, then it's likely 24
fps. So many silly variables.

Note that a projector will need to be slaved to a digital audio
reference to be able to do this -- even a synchronous motor will
drift in relation to digital audio's clock, though it will be better
than a regular projector motor.

You probably will have to manually tweak the sync -- such great fun!
