Verdict
Runway: Runway is the benchmark for professional AI video work and the first tool creative teams should evaluate. Expect to treat its output as raw material in an edit, not as finished footage.
Kling AI: Kling is one of the top general-purpose video models and a must-test for image-to-video work where subject consistency matters. Compare it head to head with Sora and Runway on your own footage before committing to a plan.
