Runway Gen-4 is the model creative directors actually open Runway for. The stylistic range - from gritty handheld doc to glossy product cinema - is unmatched, and the per-frame Motion Brush + Camera Controls give real shot-level direction.
Gen-4 trails Veo 3.1 by a hair on raw fidelity but pulls ahead on flexibility. The Act-One feature, which transfers performance from a reference video onto a generated character, is genuinely unique.
Pricing is competitive: ~$0.28/second at 1080p. Runway's editor integration (text overlays, sound, basic NLE) means many users never need to export to Premiere.
Verdict: the strongest pick for creative pros who want to direct the model, not just prompt it. We score it 9.1/10.
