Netflix explains how the image quality of your favorite films and television programs has been silent, and it is Film Grain



  • Netflix AV1 grain synthesis technology increases image quality
  • It also reduces file size and improves transmission performance
  • Technology has been arriving at films and television programs since March 2025

Film Grain is a kind of 'secret sauce' that makes movies look, well, as movies. Go to the cinema and, although you will barely notice, these imperfections that move through the image give it a depth that is difficult to recreate digitally.

Well, now Netflix has revealed in a Techblog post that has found a better way to do it, with a new technique that also easily improves reproduction stability, while reducing errors and rejection. It has been implemented worldwide since March, with transmissions enabled for FGS now available on compatible devices.
