Flow is a Google-built creative interface for AI-driven filmmaking that connects high-performance generative models (notably Veo 3) with an intuitive prompt-driven workspace. Filmmakers describe scenes in everyday language and Flow orchestrates text-to-video, text-to-image and language models (e.g., Veo 3, Imagen, Gemini) to produce cinematic clips with synchronized native audio, dialogue, ambient sound and music. It exposes project and scene management views, prompt controls and generation modes so creators can iterate quickly, combine multimodal assets, and export short cinematic sequences. Flow's value lies in unifying advanced generative models into a single creative UX tailored to storyboarding, rapid prototyping, and production-grade scene generation.
