# Human Provenance in Film

> A free, open standard for disclosing AI use in film and television. Productions are classified into three categories (No AI Used, Assistive AI, or Generative AI) through a producer-signed declaration that travels in the film's existing chain-of-title and delivery documentation. The standard is a draft (v0.9) and is open for public consultation until 31 October 2026.

The organising principle is whether AI output is present in the finished film, and whether it processed human work or originated new content. No AI output means No AI Used. AI that processes human-created material is Assistive AI. AI that originates new content appearing in the finished work is Generative AI. Classification is a producer declaration, not a technical detection.
