Runway generates short clips. Long Story assembles the whole film.
Runway is a powerhouse for short, high-end generative video clips — a few seconds of gorgeous motion. But building a full-length video from clips is slow and, at per-second generative pricing, extremely expensive. Long Story takes a different route for long-form: it generates a scene image for every moment and animates it with depth-aware parallax, so a 10-hour video costs a few dollars, not a fortune.
Runway is outstanding for short, cinematic generative clips and VFX. For that work it's a top tool — this page is for creators who need affordable full-length videos.
