Kling 4.0 Full rollout: 30 seconds 1080P video costs approximately 16 yuan, 4K HDR yet still requires waiting
Beating AI news flash: Kuaishou's Kling AI on October 15 is now fully available Kling 4.0. Previously,Kling 4.0 Flash opened access to some paid users for trial use at the end of September Compared with 3.0, the new model extends the duration of a single video generation from 15 seconds to 30 seconds, and supports up to 10 keyframes, allowing creators to specify character movements, scene changes, and shot pacing.
The all-in-one reference function has also been upgraded, supporting the combination of up to 15 assets in a single generation, including images, videos, and character subjects. Creators can have AI reference the camera movement and actions of an existing video, then replace its characters, products, or background.
Kazhike's test found that generating a 30-second 1080P video requires 450 credits, equivalent to approximately 16 yuan at its membership pricing, excluding the cost of repeated generations.
Kling has also upgraded its creation page, adding timeline, canvas, and Agent functions, and supports calling MCP、CLI via Kling 4.0, allowing AI Agent to automatically generate videos and produce batches of assets.
However, 4K output is not newly added; 3.0 already supported it. The genuinely new 10-bit HDR output remains unavailable, and video continuation of up to 2 minutes and the developer-facing Kling 4.0 API have also not yet launched.

AI-assisted interpretation
The following is analysis, separate from reported facts. Verify important claims independently.
This update mainly adds a longer video length per generation, along with greater control over keyframes and reference assets. Creators can specify actions, scene changes, and shot pacing, and can also reference the camera movement and actions of existing videos while replacing characters, products, or backgrounds. The approximately 16 yuan cost stated in the article comes from a single test and conversion based on the corresponding membership pricing; it does not represent a fixed price for all users or all generation tasks.
Why it matters to readers
Longer single-generation durations, more reference assets, and automated calling capabilities may reduce the work involved in segmented production and manually organizing assets, but the HDR, long-video continuation, and developer API mentioned in the article remain unavailable.
New users should focus on 30-second generation, keyframe control, and reference asset functions; before trying them, they should understand the credit consumption and reserve additional budget for repeated generations.
Risks and unknowns
The approximately 16 yuan figure is only Kazhike's test-based conversion using its membership pricing; the actual cost for other users cannot be confirmed from the original article.
The original article does not provide the specific total cost that repeated generations may incur.
Not specified in the original text 10-bit HDR, maximum 2-minute continuation shooting and Kling 4.0 API release date.
