RedBlue allows content producers to create "hypervideo" (interactive online video), such as choose-your-own-story films.This is achieved by annotating videos with time-based links and UI using our open standard, HVML (Hypervideo Markup Language).Hypervideo provides a more immersive experience than regular video, offering higher audience engagement rates, more rewatchability, better brand recall with ads, and a unique selling point for filmmakers.
