THE GUIDE

Explore Kling 4.0

01

What changed in Kling 4.0?

Kuaishou positions this release around large-scale motion, complex camera movement, and longer continuous storytelling. The official announcement also names Omni Reference and multiple keyframes. These are model-level capabilities, not a promise that every distributor exposes every input in the same way.

The launch announcement says developer API access will follow. Some third-party catalogs already list Kling v4 variants, but that does not establish access through API Mart or through VideoNira. We will update this page when a production integration has been verified.

02

Plan the shot before collecting references

Write one sentence for the visible action and one for the camera path. Decide which image fixes appearance, which image fixes the environment, and whether a keyframe is truly necessary. More references are useful only when each has a clear job.

For a product film, begin with a clean product frame, describe the movement around it, and reserve later keyframes for meaningful changes in angle or position. Review continuity, logos, text, faces, and hands before using the result in public work.

03

What to check when access opens

Confirm the exact API model ID, supported input combinations, output resolution, audio options, duration range, provider price, error behavior, and commercial terms. A model name on a marketplace is not enough to set a reliable customer credit price.

COMMON QUESTIONS

Answers at a glance

Can I generate with Kling 4.0 in VideoNira today?

No. This is a research guide. VideoNira has not enabled Kling 4.0 or live generation.

Does every Kling 4.0 endpoint accept 15 references?

Do not assume so. The official launch describes the model capability; endpoint-specific limits need separate verification.
