S16P

S16P is a term used in motion picture film production to denote a variant of the Super 16 format, typically associated with stock or workflows intended for positive prints rather than the standard negative path. The exact meaning of the “P” can vary by supplier or lab, but it is commonly taken to indicate a positive-print workflow or stock category within Super 16 material.

In technical terms, Super 16 enlarges the usable image area on 16mm film by using the frame area that, in standard 16mm, is allocated for the soundtrack. This yields a larger image area and allows for widescreen compositions when cropped for release, commonly producing aspect ratios around 1.66:1 to 1.85:1 depending on postproduction decisions. The S16P designation reflects compatibility with that broader image format and with positive-print processing, though the precise interpretation can differ among manufacturers and labs.

Use of S16P is most associated with independent, documentary, and low-budget filmmaking, where the advantages include greater perceived resolution and flexibility in postproduction. Shooting in S16P often requires camera setups or gate modifications compatible with Super 16, and labs must be prepared to process and deliver positive prints or to provide a workflow that preserves the intended look. In modern production, digital workflows have reduced reliance on film formats like S16P, but the term remains in circulation among cinematographers and labs that work with 16mm stock.
