Kling 4.0 AI Video Generator

Precise Multi-Keyframe Control

Kling 4.0 supports up to 10 keyframe inputs to guide character states, scene changes, and key narrative moments. Creators can define opening and closing frames or add intermediate checkpoints for more detailed control over a sequence.

This flexibility helps align camera direction and pacing with a planned storyboard. For story videos and advertising concepts, multiple keyframes provide clearer visual guidance while helping reduce character drift and unwanted style changes.

Native 30-Second Generation

Kling 4.0 generates videos up to 30 seconds long in a single pass, allowing a setup, action, and resolution to develop within one sequence. Native generation reduces the need to assemble shorter clips and reconcile differences between them.

Time-based prompts and keyframes provide additional control over narrative pacing. The longer duration suits short dramas and product demos that need space for several connected visual moments.

4K Detail and 10-Bit HDR Output

Kling 4.0 supports 4K output and 1080p 10-bit HDR, bringing finer visual detail, richer tonal gradation, and smoother transitions between light and dark. These capabilities help preserve textures and subtle lighting differences in demanding scenes.

Backlit portraits, night environments, and product close-ups benefit from better-preserved highlights and shadows, with reduced color banding. Support for a 21:9 ultrawide aspect ratio also provides more composition space for cinematic scenes and brand films.

Consistent Characters & Brands

Kling 4.0 combines up to 15 reference inputs across images, videos, voices, and elements. Images establish appearance, videos guide movement and camera direction, and voice references help maintain a recognizable vocal identity.

This capability of reference to video brings visual and audio guidance into the same generation process. It is particularly useful for recurring characters, branded subjects, and serialized content that require a consistent identity across changing scenes.

Targeted Video Editing

Kling 4.0 supports targeted changes to character expressions, body movements, backgrounds, visual styles, and camera direction. Specific details can be revised while preserving surrounding content, reducing the need to regenerate an otherwise usable scene.

The model accepts one primary video and additional video references, with up to five video inputs totaling 30 seconds. Pollo AI’s AI video editor also provides a dedicated entry point for prompt-based video refinements.

Reference-Based Creative Recreation

Kling 4.0 uses reference videos to guide narrative pacing, shot composition, transitions, and creative expression. Existing concepts can be adapted with different products, characters, or environments while retaining the structure that makes the sequence effective.

For product videos, this enables a single creative direction to support multiple collections, product variations, or campaign themes. Reference-led recreation reduces the planning required to develop each version from scratch.

Voice Generation in 9 Languages & Regional Dialects

Kling 4.0 supports voice generation in Chinese, English, Japanese, Korean, Spanish, Portuguese, German, French, and Hindi. Regional options include Cantonese and Sichuanese, alongside accents such as American, British, and Indian English.

Voice references help preserve character identity across scenes, while language and accent choices support localized storytelling. For additional audio production, Pollo AI offers separate tools for voiceovers and custom sound effects.

Video Extension Up to Two Minutes

Kling 4.0 supports video extension across multiple generations, allowing an uploaded clip to develop into a sequence up to two minutes long. This gives actions, emotional arcs, and connected story beats more time to unfold.

Reference-guided consistency helps maintain character appearance and visual style as the sequence grows. The extended format suits brand stories, short dramas, and performance videos that need more room than a single 30-second generation.
