A leader 1 or a spacer for cine-film consists of an emulsion-free perforated strip which is rendered opaque by having titanium oxide incorporated in the plastics material from which it is made. Reference marks may be distributed along the strip, the distance between two reference marks corresponding to a frame length of a cinefilm with which it may be desired to synchronize a tape.
