常见问题

How much does the Kling 3.0 API cost?

Pricing depends on mode (std/pro), duration (3–15s), and sound. Default std 5s with audio costs 300 credits. The pricing formula is: std no-audio 40/s, std with-audio 60/s, pro no-audio 54/s, pro with-audio 80/s.

What is the difference between Pro and Standard mode?

Pro mode produces higher quality videos with better motion and detail. Standard mode is faster and costs fewer credits. Specify via the "mode" parameter (std or pro).

Can I generate videos from images?

Yes. Provide image URLs in the request and the model auto-detects image-to-video mode. You don't need to set the task type manually.

What video durations are supported?

Kling 3.0 supports 3–15 second video generation. Set the "duration" parameter accordingly. Default is 5 seconds.

What is multi-shot mode?

Multi-shot mode lets you create videos with multiple scenes, each with its own prompt and duration. Set multi_shots to true and provide a multi_prompt array.
