Operator guidance

As of mid-2026, Seedance 2 Standard ($0.36/s) supersedes Gen-4.5 as the Runway quality flagship — it adds V2V, native audio, 4K output, and clips up to 15s. Gen-4.5 ($0.12/s, 12 credits × $0.01/credit) remains the choice when T2V+I2V quality is required but audio, V2V, and 4K are not needed — at 3× lower cost than Seedance 2 Standard (720p). Gen-4 Turbo ($0.05/s) for I2V-only at minimum cost.
