How It Works
Runway uses its proprietary Gen-3 Alpha model to generate video from text prompts, images, or existing video clips. Users describe their desired scene and the AI generates realistic video sequences with natural motion, lighting, and physics. The platform also offers AI-powered editing tools including green screen removal, motion brush for selective animation, object removal, and style transfer. The web-based interface makes it accessible without installing software, and the API enables integration into professional production pipelines.
