Runway's fourth-gen video model — consistent characters and cinematic motion from a single prompt.
Gen-4 is Runway's leap forward in generative video. The headline feature is character and object consistency: describe a person once and they stay the same across shots. Combined with improved motion coherence and the familiar Gen-3-style editor, it's the model filmmakers reach for when they need a controllable, shot-based pipeline rather than one lucky clip.
Who it's for: Filmmakers, advertisers, and content teams who need consistent characters, props, and locations across multiple generated shots.
Reference an image and Gen-4 keeps that person, object, or location stable across shots.
Smoother physics and camera moves than Gen-3, with less morphing.
Use Gen-4 inside Runway's Editor for inpainting, motion brush, and rotoscoping.
Prompt from text or drive it from storyboard frames.
Gen-4 is the most production-minded video model Runway has shipped. For anyone building a narrative or brand video from generated clips, the consistency alone justifies the subscription.
