Abstract
An apparatus in which the video disk frames are reread while a shutter blocks the film in order to have during the rereading operation the time necessary for advancing the kinescope film without causing violent mechanical stresses. In order to pass from the television standard with 30 frames per second to the cinematographic standard of 24 frames per second, one frame out of five is not recorded on the film and the film advanced without any rereading.
