Question 1

What is Kling 4.0?

Accepted Answer

Kling 4.0 is a next-generation native multimodal video model for professional creators and commercial content teams. It combines text, images, videos, subjects, and voice references in one workflow. With 4K/1080p 10-bit HDR output, more stable motion, richer reference control, and stronger narrative capabilities, Kling 4.0 helps turn creative ideas and mixed-media assets into complete, cinematic videos with greater control.

Question 2

How do I get started with Kling 4.0?

Accepted Answer

The all-new Kling 4.0 is coming soon this October, with Kling 4.0 Flash available first to a limited group of creators. Sign up or log in to Kling Creator Studio to check whether Kling 4.0 Flash is available for your account and to follow the latest updates.

Question 3

What's the difference between Kling 4.0 and Kling 4.0 Flash?

Accepted Answer

Kling 4.0 Flash is built on Kling 4.0 and offers a subset of its capabilities. It supports text-to-video, image-to-video, and Omni Reference, with videos up to 20 seconds in a single pass and up to 720p resolution (8-bit SDR). It does not support first/last frames or multi-keyframes. Kling 4.0 Flash is available now in a limited rollout for faster, more affordable creation, while the full Kling 4.0 launches this October.

Question 4

What's the main difference between Kling Video 4.0 and 3.0?

Accepted Answer

Kling 4.0 offers longer video generation, higher output quality, more stable complex motion, and stronger multimodal control. It supports up to 10 flexible keyframes, videos up to 30 seconds, and 10-bit HDR output in 1080p and 4K. It also adds dual-channel stereo audio, broader multilingual text and speech support, and up to 15 combined reference assets, including images, videos, subjects, and voice tone. Video editing supports up to 5 clips in one task, with a total duration of up to 30 seconds.

Question 5

Can Kling 4.0 generate videos from both text and images?

Accepted Answer

Yes. In Kling 4.0, text-to-video, image-to-video, reference-based generation, video continuation, and video editing are unified into a single native multimodal workflow. Instead of switching between separate tools, you can start from text or images, add references, continue an existing video, or re-edit footage. You can move from idea to finished video from one panel in Kling Creator Studio without breaking the creative flow.

Question 6

How many keyframes does Kling 4.0 support?

Accepted Answer

Kling 4.0 supports up to 10 flexible keyframes. You can place them at different points in the timeline to guide camera movement, shot changes, character entrances, product reveals, and other key moments. This allows for more natural multi-shot transitions and greater control over the structure of a video.

Question 7

How long can Kling 4.0 generate videos?

Accepted Answer

Kling 4.0 can generate videos up to 30 seconds long in a single generation. The longer duration gives scenes, actions, emotional beats, and story developments more room to unfold.

Video extension (coming soon) lets you extend an existing video forward or backward across multiple passes, with total length reaching up to 2 minutes while maintaining continuity across the subject, scene, action, camera, and audiovisual relationships.

Question 8

What resolution and dynamic range does Kling 4.0 support?

Accepted Answer

Kling 4.0 supports 10-bit HDR output in both 1080p and 4K. It also supports a 21:9 ultrawide aspect ratio, along with 16:9, 1:1, 9:16, and Smart formats. The 10-bit HDR format provides richer color detail, smoother tonal transitions, and improved preservation of highlights and shadows, making it suitable for cinematic scenes, high-contrast environments, and commercial video content.
