Film shot at 24 frames per second (fps) used to be transfered to video, (for NTSC, nominally 30fps or 29.97fps for color) with a telecine (projector and matching video camera). The time-stretch problem was "solved" by using a so-called 3/2 pulldown on the film projector, which was gen-locked (kept in sync) with the video. Using an eccentric cam, the film was advanced (pulled down) in an irregular manner: Every other frame lasted 1 video frame [that is, two interlaced fields] whereas those in-between were held in the film projector for 3 video fields. On the resulting video transfer of the film, every time a film cut happened to fall over in the middle of a video frame, the result looked like a 1-frame dissolve; hardly noticable to most people, but a somewhat "softer" transition than the original film edit. The same sort of printing technique was sometimes used when preparing silent films (nominally 16 fps, or 1 foot per second) for projection on 24fps projectors. The result looks awful, but was deemed to be better (by someone) than the "sped up" ("undercranked") effect of showing film shot at 16fps on a 24fps projector. It sounds as if your "Girl in the Moon" DVD may have been made from such a film print. Many commericals are still shot on film, but at 30fps, to make them look better in a video transfer done 1:1, with no interpolation.
