A method of making motion picture release-print film, such as 35 mm film. The film has an enlarged frame that occupies substantially the entire width of the film that is available for the exposure of images, and the spacing between frames is minimized. Film having these enlarged frames provides an enhanced image with a minimum of film waste. Aspect ratios of 1.85:1 and 2.01:1 in the enlarged frame size are contemplated in three and four perforation formats. A digital soundtrack or other appropriate soundtrack replaces the analog soundtrack that occupies a portion of the available width. The soundtrack may provide for redundancy.
L'invention concerne un procédé de production d'un film de diffusion d'oeuvres cinématographiques, tel qu'un film 35 mm. Ce film comprend un cadre élargi occupant sensiblement toute la largeur du film disponible pour l'exposition des images, l'espacement entre les cadres étant minimisé. Ce film à cadres élargis permet d'obtenir une meilleure image avec un minimum de pertes de film. Les rapports de cadre de 1,85:1 et 2,01:1 du cadre élargi sont prévus en formats à trois et à quatre perforations. Une piste sonore numérique, ou toute autre piste sonore appropriée, remplace la piste sonore analogique qui occupe une partie de la largeur disponible. La piste sonore permet la redondance.
