Welcome to the FGSEditor Wiki

FGSEditor is a professional-grade graphical interface designed for creating, editing, and managing Film Grain Synthesis (FGS) for the AV1 video codec. It provides an intuitive environment for technical users, colorists, and enthusiasts to fine-tune synthesized grain parameters with surgical precision.

This wiki is designed to guide you through the complex world of synthetic grain, from the fundamental concepts to the advanced usage of FGSEditor. To get the most out of it, we recommend reading the pages in order:

  1. 1. Introduction to FGS: Understand what synthetic grain is and its pros and cons compared to traditional noise.
  2. 2. FGS Table Structure: Learn the exact syntax of the filmgrn1 format and every parameter it contains.
  3. 3. How FGS Works: A deep dive into the underlying mathematics, spatial grids, and stability limits.
  4. 4. FGSEditor Overview: Discover how FGSEditor simplifies all the complex processes described in the previous pages.
  5. 5. Prerequisites & Shortcuts: Ensure your system is ready and master the interface shortcuts.
