Abstract
A film video player/printer allows an operator to display a video image of a photographic film in a normal orientation while magnifying and composing the magnified image according to a desired format (vertical or horizontal) portrayed by the display. Reticle-generating circuitry selectively rotates a rectangular reticle centered on the display, the reticle portraying the border and thereby the format of a print to be made. A turntable serves for selectively rotating the film about an optical centerline of the film video player/printer, to provide for the display of the film image in the normal viewing orientation and to provide for a print corresponding to the image and format displayed. With the film being rotated about the optical centerline and with the aspect ratio of a vertical reticle being the reciprocal of the aspect ratio of a horizontal reticle, an optical print is made without any need to compose or magnify the image to compensate for any rotation of the film for printing.
