Kling 4.0

A single run now produces up to 30 seconds, long enough for a complete scene with a setup, a turn and an ending. Characters, setting, sound and style stay consistent because nothing has to be stitched together, and you can steer the pacing by describing what happens at each point in time.

Pin down the frames that matter: a character's pose, a change of scene, a plot beat. Two keyframes fix the start and the end, five mark the turning points, and ten lay out a full storyboard, while faces, style and visual details stay continuous between them.

Mix images, videos, subjects and voices in one request: up to 10 images, up to 5 videos with a combined length of 30 seconds, 7 subjects and 3 video subjects. Images anchor the look, videos carry the motion, voice references hold the voice, and subjects stay recognizable from the first frame to the last.

Give Kling 4.0 a reference video and it picks up the pacing, shot order and delivery, then rebuilds the piece with your own product, character or footage. A format that already works becomes your version without planning the concept from scratch.

Change a character's expression, a body movement, the camera angle or move, the overall style or the background, and the rest of the frame stays as it was. Editing takes up to 5 input videos, one as the main clip and the others as references, with each clip and the total footage kept within 30 seconds.

Running, fights, chases, explosions, dives and fast spins keep a clear, stable picture with believable movement. Push-ins, pull-outs, pans, tracking shots and orbits look smoother, and cuts between shot sizes flow naturally.

Output in 4K or 1080p with 10-bit HDR for richer color and smoother gradients. Backlit, night and neon scenes keep more detail in the highlights and shadows with less banding, which leaves room for color grading. A 21:9 ultra-wide ratio is available for a cinematic frame.

Audio comes out in two-channel stereo, and lip movements match the dialogue more closely, so voices, sound and performance land together. Speech covers Chinese, English, Japanese, Korean, Spanish, Portuguese, German, French and Hindi, with accents and dialects such as American, British and Indian English, Cantonese and Sichuanese.

Slogans, packaging, shop signs and subtitles render clearly in the same nine languages and stay legible while the camera moves or the scene changes. Emoji and logos come through cleanly too, so the key information in a shot can actually be read.

Upload a video or pick one you generated with Kling, then continue it forward or backward. Repeat the extension until the piece runs up to two minutes, giving actions, emotional build-up and multi-part stories room to play out.

A built-in prompt expansion step turns a one-line idea into a full plot with a setup, development and payoff. It plans the scenes, camera moves and cuts for you, and keeps every shot tied to what you asked for.

Supported looks include cinematic, animation, fantasy, pixel art and felt. The model holds a distinctive style across a whole piece, from film and short drama to ads, animation and music videos.
