ISO 12612:2016
Cinematography — Interchange of post-production sprocket-based materials
ISO 12612:2016 specifies certain parameters and technical characteristics of post-production motion-picture materials used in the international exchange of 35 mm and 70 mm picture and sound elements.
ISO 12612:2016 further specifies a method for the evaluation of picture-image quality based on a standardized test image contained in the post-production picture elements.
