Runway Gen-4.5, one paragraph deep
Runway Gen-4.5 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-4.5 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 3.1. For volume, Kling. Gen-4.5 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.
