Mux has partnered with Contentful, an API-first content platform, to improve video content management and streaming on digital channels. The latest update to the Mux Contentful app allows users to add subtitles and captions for on-demand videos directly in their editorial dashboard. Additionally, users can now use Mux Player to stream high-quality video across multiple platforms. Audio normalization is also supported as an API option, ensuring consistent audio levels. The update includes additional metadata fields and improvements to the mux-uploader-react library.
