How to choose
Ask three questions before you subscribe.
Will the clip be used commercially? If yes, Runway is the default. Kling's terms require written permission for commercial use and Kling branding on outputs, which most brands and agencies cannot accept. If you only make personal edits, fan videos or tests, this question does not decide it.
How long is your longest shot? If you need 11 to 15 seconds of continuous action, Kling does it in one pass. Runway tops out at 10 seconds per Gen-4.5 generation, so you will cut between clips or extend.
Do you edit real footage? If you shoot live action and want AI to change it, Runway's Aleph 2.0 is the tool. Kling is a generator.
A practical setup. Many creators keep a Runway Pro plan for client work and editing, and try Kling on a $10 month or a small credit pack to see whether its long clips suit their style. Because Runway also runs Kling as a third party model, you can test Kling output inside Runway before deciding whether a separate Kling membership is worth it. Track how many attempts each usable shot takes in both apps; failed generations still cost credits on both, and that is where the real cost difference shows up.
Privacy
Runway's terms let it train on your inputs and outputs below Enterprise. It is a named defendant in Andersen v. Stability AI and YouTube scraping class actions pending as of October 2026, and attaches C2PA content credentials to outputs.
Kling, run by Kuaishou, grants itself a license to use your content and to train its models unless you email to revoke, per its April 21, 2026 terms. TechCrunch reported that politically sensitive prompts are blocked. Trustpilot scores are poor for both (Runway 1.2 from 366, Kling 1.2 from 415), while both rate 4.5 or higher on the App Store.
Verdict
Runway wins for anyone who sells or publishes video for a business: clear commercial rights, editing tools and team plans. Kling wins on raw clip length and native 4K for personal work. If you like Kling's output, the cleanest routes for commercial projects are getting Kling's written permission or running Kling inside Runway after confirming with Runway which terms apply.
