Runway Gen-4, one paragraph deep
Runway Gen-4 carries the longest professional memory in AI video: world references — define your characters, locations and styles once, and they persist across shots with continuity-department discipline. For campaigns and series where shot 14 must match shot 1, that’s the feature that matters, a render.
The agency-safe pick
Gen-4 is the model you hand a team that has to deliver the same world forty times: predictable, controllable, editing-native. For per-frame prompt control, Seedance 2.5 leads; for audio, Veo 3; for volume, Kling. Gen-4 is priced for production — test your hardest continuity shot on it, run the same brief through Seedance, and keep whichever universe holds together better. Both takes land in the same OpenClips library.
