current alternatives, however, due to increased complexity. The new codec requires longer encoding times vs. Our testing shows AV1 surpasses its stated goal of 30% better compression than VP9, and achieves gains of 50.3%, 46.2% and 34.0%, compared to x264 main profile, x264 high profile and libvpx-vp9, respectively. In designing our comparison tests, we aligned our approach closely to previous work by Netflix, comparing x264, x265 and libvpx. By structuring the test this way, we were able to show how the codec will perform in a true production environment compared with current widely used alternatives, such as x264 and libvpx-vp9. standard reference software encoders (i.e., H.264/AVC Joint Model or JM). practical open source video encoders that can be deployed to a practical production system, rather than merely testing efficiency vs.

We tested the new codec under conditions that closely match the most common real-world use cases for Facebook video. The Alliance for Open Media - a consortium founded in 2015 and made up of video-on-demand providers including Amazon, Facebook, Google, Microsoft and Netflix, along with web browser developers and semiconductor firms - has just released AV1 (also known as AOMedia Video 1), a new open, royalty-free video format that promises to be a significant step forward in compression efficiency.

Everything from 4K movie streaming to smartphone video chat to laptop screen sharing can be enhanced by making the video files smaller through better compression codecs. Improved video compression is important for delivering digital video files more quickly and with higher quality, while using less bandwidth and storage.
