Mux is building the future of online video infrastructure. We just announced Mux Video, a simple API to video hosting, encoding and streaming. POST a video; GET a video back that plays anywhere and is deeply optimized for the target device and user. Mux Video is powered by our first product, Mux Data, which measures video streaming performance across billions of video streams for customers like PBS, Vimeo, and the New York Times.
