Runway Gen-4.5 vs Kling 3.0 Pro
Runway Gen-4.5 and Kling 3.0 Pro both target polished, cinematic short clips for commercial work. Runway's edge is camera control and fast turnaround; Kling's edge is native audio and multi-shot generation. They are close enough in ambition that the right pick depends on the shot, not the brand.
