What Kling 3.0 can do
Kling 3.0 is Kuaishou's flagship video model. It makes 3 to 15 second clips from a text prompt or a photo: set the first frame and, optionally, the last one, and the model builds the motion in between. Kling is known for realistic physics, natural human motion and careful camera work.
Pick Standard (720p), Pro (1080p) or 4K. Sound is optional — effects, music and voices are generated together with the picture. No Kling subscription needed: you pay per second of the clip, see the price before you start, and a failed generation is refunded.
Use cases
- cinematic scenes and ads
- animating a photo with a first and last frame
- 4K clips for big screens
- clips with sound and voices for social media
How to get started
- Sign in with Telegram, GitHub or email — it takes half a minute.
- Open the Kling 3.0 page and write a prompt, optionally adding a photo.
- Check the price on the Create button and run it. The result appears on the page and in your Generations list.
- Top up when you need to — any amount, no subscription. Prefer code? Create an API key and call the same model over REST.
Prompt tips for Kling 3.0
- Write it like a shot list: place, character, action, camera move, sound.
- For a transition, upload both frames and describe what happens between them.
- Test the idea in 720p for 5 seconds; switch on 4K and sound for the final take.
The more specific the prompt, the fewer attempts you need. Instead of "a nice picture", say what exactly, where, in what light and in what style.
