Runway

Runway pairs text-to-video and image-to-video generation with a genuine editing toolkit — motion brush, camera controls, green-screen-style background removal, and inpainting for video — so it functions as both a generator and a post-production tool. Fashion video teams use it to animate lookbook stills into short product loops, extend b-roll from a shoot, or rough out concept animations before committing studio time. Its editing tools make it easier to fix or refine AI-generated clips rather than regenerating from scratch every time something's slightly off. Render times and consistency across longer clips are still the main constraints for full campaign-length video work.
