Runway

What Runway does

Runway generates video from text, images and reference clips, and wraps that generation in editing tools rather than leaving you with isolated clips. Its model family supports image-to-video, video-to-video restyling, camera direction, motion brushes for animating specific regions, and reference-based consistency so a character or product looks the same across shots. Supporting features include background removal, frame interpolation, inpainting for video, and a timeline for assembling results. It is used in advertising, music video work and previsualisation, and it has been adopted by production companies rather than only by hobbyists. It suits creative teams that need controllable shots and a workflow beyond a single prompt. The limitations are clip length and cost: individual generations are short, extending them compounds any drift in appearance, and credits disappear quickly at higher resolutions, so a finished minute of video takes many attempts and a real budget.

How to use it

Sign up at runwayml.com; a one-time free credit allowance lets you test generation before committing. The most reliable first run is image-to-video rather than text-to-video: generate or upload a still that already has the framing and characters you want, then describe only the motion. That single habit removes most of the frustration people hit early. Add camera controls for pans and pushes, and use the motion brush to move one element while the rest of the frame stays still. Reference images help hold a character across shots, though not perfectly. Assemble clips on the built-in timeline or export and cut them elsewhere. Budgeting is the main trap: credits are consumed per second of output and scale with resolution and model, failed generations still cost, and unlimited generation only appears on higher plans in a slower queue. Plan on generating several takes of each shot and keep resolution low until the motion is right.
