Principles of Work
Runway Gen 4.5 is Runway's flagship image-to-video model, designed to generate highly realistic videos from a single image. After you select an image, enter your scene text and scene action, and choose your camera motion settings, the model produces smooth, detailed animations with realistic lighting, expressive character movement, and stable visual consistency throughout the scene.
