Improving Netflix Video Quality with Neural Networks

Published: 30 April 2023 Publication History

Abstract

Video downscaling is an important component of adaptive video streaming, which tailors streaming to screen resolutions of different devices and optimizes picture quality under varying network conditions. With video downscaling, a high-resolution input video is downscaled into multiple lower-resolution videos. This is typically done by a conventional resampling filter like Lanczos. In this talk, we describe how we improved Netflix video quality by developing neural networks for video downscaling and deploying them at scale.
