Runway

Runway is an AI video and creative production platform built for generating and editing video, images, and audio from a single workspace. Its Gen-4 family of models handles text-to-video and image-to-video generation with attention to character and scene consistency across shots, alongside tools like Act-One for performance capture, motion brush, inpainting, green screen, and camera control that give users finer directorial control than a typical prompt box. It's used by filmmakers, ad agencies, and independent creators who want to storyboard, generate footage, and finish shots without leaving the tool, and increasingly by production studios integrating AI-generated elements into traditional pipelines.

What sets Runway apart from most video generators is that it was built by people with a background in filmmaking and VFX, so the product leans toward professional workflows rather than novelty clips: it has features like motion tracking, frame interpolation, and a research-driven approach that produced some of the earliest usable text-to-video and inpainting tools in the space. It's available as a web app and through an API for developers who want to build generation into their own products, and the workspace also surfaces select third-party models so users aren't locked into only Runway's own tech.

Runway has raised funding from major studios and investors and has partnerships with companies like Lionsgate, positioning it less as a consumer toy and more as infrastructure for AI-assisted film and content production.
