Runway Gen-4.5

What is Runway Gen-4.5?

Runway Gen-4.5 is an AI video generator that turns text or images into short cinematic clips. It prioritizes realistic motion, stronger physics, and faithful prompt following so scenes feel like real takes. Outputs run up to 10 seconds at 1080p and include image-to-video, keyframe controls, and API access. Built for ads, storyboards, VFX tests, and product shots, it helps creators iterate fast and produce production-ready drafts.
