Runway Gen-4: AI video generation with world consistency
The model release that made same-character-across-scenes a product feature, not a hack.
Open runwayml.com →Consistency comes from references, not prose: feed the model 3-5 reference images (Runway Gen-4 references, Midjourney's omni/character/style reference, Veo ingredients in Flow, Sora cameos) and pin palette, wardrobe, and lighting in a reusable prompt template. Because every shot generates independently, re-describe the character identically each time. For brand systems, lock a style reference once and reuse it across all assets so your feed looks like one company made it.
A quick orientation. The real value is below: resources worth your time, from people who've actually done it.
