What is Runway?

Runway is the creative suite behind Gen-series video models, used by filmmakers and marketers for text-to-video, image-to-video, and AI-powered editing tools. You can try it at runwayml.com.

Why prompt quality matters in Runway

Runway rewards director-style prompts and offers image-to-video control — meaning your words plus a reference frame steer everything. Structured intent saves credits and reshoots.

Runway prompting tips that actually move results

One camera instruction per generation; conflicting moves create wobble.
Describe motion speed (“gentle drift”, “rapid push-in”) — defaults are slower than people expect.
Keep style words consistent across clips you plan to cut together.

Frequently asked questions

Is Runway free?

A limited free tier exists; serious use needs a subscription with monthly credits.

Text-to-video or image-to-video?

For brand work, image-to-video from a strong still gives far more control — generate the still first (see our Midjourney and Flux guides), then animate.

Which export do I use?

The Kling/Runway export formats your scene, camera, action, and style for Runway's generators.
