A Large-Scale Comparison of x264, x265, and libvpx
by Jan De Cock, Aditya Mavlankar, Anush Moorthy, and Anne Aaron With 83+ million members watching billions of hours of TV shows and movies, Netflix sends a huge amount of video bits through the Internet. As we grow globally, more of these video bits will be streamed through bandwidth-constrained cellular networks. Our team works on improving our video compression efficiency to ensure that we are g
Toward A Practical Perceptual Video Quality Metric
by Zhi Li, Anne Aaron, Ioannis Katsavounidis, Anush Moorthy and Megha Manohara At Netflix we care about video quality, and we care about measuring video quality accurately at scale. Our method, Video Multimethod Assessment Fusion (VMAF), seeks to reflect the viewer’s perception of our streaming quality. We are open-sourcing this tool and invite the research community to collaborate with us on this
Per-Title Encode Optimization
We’ve spent years developing an approach, called per-title encoding, where we run analysis on an individual title to determine the optimal encoding recipe based on its complexity. Imagine having very involved action scenes that need more bits to encapsulate the information versus unchanging landscape scenes or animation that need less. This allows us to deliver the same or better experience while
High Quality Video Encoding at Scale
At Netflix we receive high quality sources for our movies and TV shows and encode them to the best video streams possible for a given member’s viewing device and bandwidth capabilities. With the continued growth of our service it has been essential to build a video encoding pipeline that is highly robust, efficient and scalable. Our production system is designed to easily scale to support the dema

Daala video compression Daala is the code-name for a new video compression technology. The effort is a collaboration between Mozilla Foundation, Xiph.Org Foundation and other contributors. The goal of the project is to provide a free to implement, use and distribute digital media format and reference implementation with technical performance superior to h.265.

Open-Sourced H.264 Removes Barriers to WebRTC
When it comes to making collaboration technology such as high-definition video open and broadly available, it’s clear that the web browser plays an important role. The question is, how do you enable real-time video natively on the Web? It’s a question that folks are anxious to have answered. WebRTC–a set of enhancements to HTML5–will address the issue head on. But, there is an important hurdle tha
WebM and Broken Promises
An unofficial blog that watches Google's attempts to move your operating system online since 2005. Not affiliated with Google. Send your tips to gostips@gmail.com. Two years ago, a surprising post from Chromium's blog announced that Google Chrome will drop support for H.264 HTML5 videos. "Though H.264 plays an important role in video, as our goal is to enable open innovation, support for the codec
Video Conferencing features of Intel® Media Software Development Kit
Abstract This article explains how to use the new and optimized video conferencing features available as part of Intel® Media SDK. Features common to video conferencing or streaming workloads are detailed together with source code references illustrating how a developer may use the feature in an application. Introduction The Intel® Media Software Development Kit (Intel® Media SDK) is a software de
