AI Video with Runway
Runway Gen-3 generates video from text prompts or still images. The results are increasingly cinematic — smooth motion, realistic physics, and controllable camera movement. This is the frontier of creative AI.
Start from an image, not text. Generate a still in Midjourney, then animate it in Runway. This gives you much more control over the starting composition.
Camera motion prompts: 'slow push in', 'tracking shot left to right', 'drone shot rising above'. Runway understands cinematic language.
Keep clips short (4-10 seconds) and edit them together. AI video works best in short bursts stitched into a sequence.
Motion brush lets you define which parts of the image should move and which should stay still. Essential for controlled, natural-looking results.
