The problem with transferring 24 fps film to video is the 59.94 Hz field
rate.  The result is known as the 3-2 pulldown method, whereby one frame
of film is scanned for three field of video and then the next frame of film
is scanned for two fields of video.  The process is repeated.  This results
in some of the jerkiness that you see.

You tend to see alot of videos shot using 30 fps and I've seen some TV
shows shot at 30 fps.
