Runway

Runway とは？

Runway is an AI video platform for generating and editing video in the browser. You can create clips from text prompts or images, then adjust them with camera controls, reference images and a set of editing tools. Filmmakers, video editors, agencies and content creators use it for previsualization, short-form content and visual effects. Runway differs from simple text-to-video apps by combining generation with production tools. Alongside its own video models, it offers features such as background removal, inpainting for video, and character performance tools that map an actor's expressions onto a generated character. It is built with professional creative work in mind. Usage runs on credits, with a free plan that includes a limited one-time allowance and paid plans for regular use.
