Kling 4.0

What's new in Kling 4.0
Omni Reference with up to 15 inputs
Combine up to 10 images, 5 videos (up to 30 seconds in total) and 7 subjects in one generation. Reference videos steer performance, camera movement and pacing, and a subject can carry its own voice.
Big motion, steady camera
High-speed action, continuous movement, tracking shots and orbiting camera moves stay stable and coherent from start to finish.
Dialogue in many languages
Characters can speak Chinese, English, Japanese, Korean, Spanish, Portuguese, German, French and more, with accents and dialects such as Beijing Mandarin, Cantonese, and British and American English. Kling 4.0 generates the sound in two-channel stereo with more accurate lip sync.
More ways to work with Kling 4.0
Edit a video in place
Add, change or remove subjects and backgrounds in an existing clip, or change its style, weather, colour, materials, shot size and camera angle while the rest of the scene holds steady.
Remix a video you admire
Borrow a reference video's pacing, shot order and delivery, then swap in your own products, characters and assets for social posts and product ads.
Prompts up to 8,000 tokens
Write one line or a full scene breakdown. Kling 4.0 fills in, expands and polishes short prompts.
Readable on-screen text
Text in many languages, emoji and logos stay clear and stable, even through camera moves and scene changes.
