This Recommendation specifies the dimensions of area to be scanned on 16 mm and 35 mm motion picture films. Its purpose is to be a reference document for harmonizing the areas used in film cameras, film projectors, telecines and test films for television purposes. The dimensions of the recommended areas are based on how film material and film technology are actually used for television production and reproduction. The technical properties of film and television techniques are taken into account, as well as the artistic criteria for format harmonization from shooting to presentation. The listed dimensions are based on key values taken from film industry standards and practices for exposure, printing, projection as well as past and present technology of television reproduction.
