The short answer

Kling and Runway are both AI services that make videos from text or images. Which fits better depends on your goal, such as showing big character movement or controlling camera moves closely. Length, quality and pricing change, so check the official sites before use, and compare by trying both with the same image.

What is the difference between Kling and Runway?

Both can turn images into videos. Choose by thinking about what kind of motion you need most and how much control you want.

Many people use Kling with a focus on character movement and changing expressions, and Runway with a focus on a workflow that includes camera moves and editing tools. Both update quickly, though, and what they can do keeps changing. Treat the table below as a list of things to check when choosing.

How do you compare Kling and Runway?

Steps to compare the two with the same image

Pick one image to animate (one with a large face and a simple background is easiest to test)
Decide on just one motion and write a short English prompt
Make one clip each in Kling and Runway with the same image, prompt and aspect ratio
Compare whether the face stays the same, whether hands and hair move naturally, and whether the camera follows the instructions
Also note the time taken and credits used, and choose the one that suits the videos you make most

Prompt example for comparing: The girl slowly turns her head toward the camera and smiles. Her hair moves gently in the wind. The camera slowly pushes in.

What it asks for: a slow head turn toward the camera and a smile, hair moving softly in the wind, and a slow camera push-in.

When should you use Kling, and when Runway?

It is easier to choose if you decide whether character movement or camera work and editing is the main point.

Video you want	How to think about it	Notes
A character turning or walking	Compare how character movement comes out	Watch closely whether the face changes
Showing scenery with the camera	Compare how camera moves are specified	See how pans and dolly moves work
Joining short cuts	Compare editing tools and export	Where can the joining be done
Vertical videos for social media	Compare aspect ratio settings	Can it make 9:16

What are common mistakes and how do you fix them?

Problem	Cause	Fix
The face changes midway	Motion too big or face too small	Limit to one motion and use an image with a large face
Almost nothing moves	Vague motion words	Write exactly what moves and how
The camera moves on its own	No camera instruction	Add words that stop it, such as static camera
Hands melt or multiply	Complex hand motion	Use an image with hands down and don't describe hand motion
You can't tell the difference when comparing	Conditions not matched	Compare with the same image, text and aspect ratio

How do you check pricing and clip length?

Check the pricing page and help pages on each service's official site for the current details.

AI video services often charge by credits (units of usage), and the amount used changes with length and quality. Plan names and contents also change often, so this page doesn't list numbers. For commercial use, always check the terms for each plan too.
