In the case of television display formats given as letterbox or sidebar, the center of the television scanned area (television production aperture), safe action area, and safe title area shall coincide with the centers given in the appropriate camera aperture documents

6、. In the case of television display formats given as full screen, the centers of the television scanned, safe action, and safe title areas may be jointly moved (panned) into the cropped area. Such movement shall not cause the scanned area (television production aperture) to move outside the extremes

The display image is deanamorphic (unsqueezed). 5 Composed aspect ratio is the aspect ratio for which the image was originally composed and at which it was originally intended to be displayed. All dimension calculations were done to at least four decimal places, but aspect ratios

14、 are nominally indicated. 6 Scanned area shown differs from the corresponding area in type C (4 perf) apertures to allow room for mechanical splices in 3-perf film.

16、duction and clean apertures A marking on the reticle of the film camera viewfinder may be used to indicate the production aperture (scanned image area). Since the great majority of television receivers display less than the clean aperture, it may be desirable to indicate smaller areas in the film ca
