ISO/IEC TR 23002-9:2024 PDF

Overview

ISO/IEC TR 23002-9:2024 is an important technical report from ISO and IEC that addresses film grain synthesis technology for video applications. As part of the MPEG video technologies series, this document provides guidance for preserving or recreating the distinct appearance of film grain in digital video content. Film grain-the random, grainy effect seen in traditional celluloid film-is often desired in both cinematic productions and digital video for artistic effect or to mask compression artefacts. This report outlines methodologies for analyzing, modeling, synthesizing, and blending film grain within various MPEG video coding standards, supporting improved subjective quality and more efficient video compression.
