Which Model Fits Your Shot?
Kling 4.0 and Runway are both available in the EveryGen video editor, so you can run the same idea on each and compare. They are suited to different jobs.
Kling 4.0 is built for longer, reference-guided scenes. The Runway option is a quick way to make short cinematic clips from text or a single image.
Key Differences
Duration
Kling 4.0 lets you choose any length from 4 to 30 seconds, so one generation can hold a complete beat. The Runway option generates 5- or 10-second clips, which suits single shots you plan to cut together.
References
Kling 4.0 can combine image, video and audio references to keep a subject, setting or rhythm consistent. Runway on EveryGen starts from a prompt or a single image.
Cost per Shot
Kling 4.0 is billed per second, so longer scenes cost more. Runway is billed per clip, which is economical for quick drafts. The table shows each model’s current credit range, and the editor shows an exact quote before you confirm.
Framing
Kling 4.0 supports 16:9, 9:16 and 1:1. Runway adds 4:3 and 3:4, which is useful for some feed and print layouts.
What Creators Say About Kling and Runway

Kling AI
…Kling ai is a very performant ai video generator, it understands prompt, it gives the best camera motion performance, maybe it's not very good in image generation, but in others fields it performs very well.

Kling AI is a great tool for creating AI-generated videos, and I genuinely enjoy using it. … facial consistency is a major issue. When animating images, the AI sometimes changes people’s faces or facial features…

I like Klingai, I've produced some amazing artwork with it, yes! You've got to write your prompts very carefully! If you use the web version in browser on a PC the features and results are amazing, but the mobile app is very limited…

Runway
controversial but I think runway is pretty good! I like the workflows product and I'd rather have more credits than wait for hours in the unlimited queues

I’ve made some genuinely awesome stuff on here but I’ve also wasted a ton of money on failed, flawed, or otherwise compromised generations that had nothing to do with my prompts. … But when it works, it’s awesome, amazing technology. …

I love runwayml. The only issue I have is paying for their experimenting. When I write a precise prompt and the generation is completely off with little attention to the prompts, I should not have to pay for it. …

…The videos it generates are decent at best, but if you’re a creator and it doesn’t get your content right, you just wasted a ton of credits for nothing. …
