RunwayML Gen4 Turbo

Runway Gen-4 Turbo image-to-video for fast still-driven motion.

Choose Gen-4 Turbo when the input image already carries the composition and you mainly need a motion pass. The control surface is direct: prompt, image, duration, aspect ratio, and seed.

Use the prompt for motion, camera direction, timing, and what should stay stable. It is less about rebuilding the image and more about finding a convincing movement from it.
