What's new in Kling 4.0

Three things you can see in the clips. Each one came from a single prompt in ChatCut.

Three shots, one generation

Write the shots in order and Kling 4.0 cuts between them inside one clip. This 10-second car ad is a close-up, a tracking shot and an aerial, from one prompt.

21:9 · 10s · 1080p

Cinema-wide 21:9

Kling 4.0 renders 21:9 natively, alongside 16:9, 9:16 and 1:1, so a wide shot needs no crop.

21:9 · 10s · 1080p

Sound comes with the shot

Every clip has native audio. Write the sounds into the prompt; turn the sound on to hear this one.

Direct it with your own inputs

Kling 4.0 takes images, frames and videos in one request. Here is what went in, and what came out.

Characters and a world, from reference images

Two character sheets and one set, plus a clip whose camera move to copy. Name each one in the prompt and Kling keeps them apart.

  1. @image_1: Otter @image_1 Otter
  2. @image_2: Fox @image_2 Fox
  3. @image_3: Village @image_3 Village
  4. @video_1: Camera move @video_1 Camera move
Kling 4.0 · 16:9 · 10s · 1080p
See the prompt

Stop-motion felt animation. The otter from @image_1 (chestnut brown felt, mustard-yellow knitted raincoat with wooden toggles) and the fox from @image_2 (orange felt, white muzzle, long teal-green knitted scarf) walk side by side along the dirt riverside path of the felt village in @image_3 at dusk, lanterns glowing. The otter is on the LEFT and the fox on the RIGHT; the fox points up at the lanterns and the otter waves a paw. Follow the camera path and pacing of @video_1: track alongside them, swing around to a front-facing medium shot, then rise slightly at the end to reveal the wooden bridge and the river. Take only the camera move from @video_1, not its person, road or sea. Handmade felt textures with visible fibres, slightly stepped stop-motion movement, warm amber lantern light against dusk blue. Sound: soft footsteps on gravel, river water, crickets, a gentle music-box melody. No people, no text.

Start and end on frames you choose

Give Kling the first and the last frame, then describe what happens in between. Here a platform at dawn becomes a seat by the train window in one move.

0-5s: on the misty seaside platform at dawn (@first_frame), the woman in the long red coat waits with her suitcase; a silver commuter train glides in from the left and stops beside her, its doors sliding open, and she turns and steps aboard. 5-10s: the camera follows her through the doorway into the carriage; she sits down by the window as the train pulls away, the coastline sliding past and the low sun breaking through the mist onto her face (@last_frame). Keep her face, short black hair, red coat, cream scarf and brown suitcase the same throughout. One continuous camera move, 35mm film look, fine grain. Sound: sea wind, train brakes hissing, a door chime, then the soft rhythm of wheels on rails. No text, no other people.

Thirty seconds, one take

No images at all: one prompt that describes the walk in four time segments. The camera follows him from the market to the rooftop without a cut.

Kling 4.0 · 16:9 · 30s · 1080p
See the prompt

One continuous 30-second take with no cuts. 0-8s: night, a narrow lantern-lit street market just after rain; the camera follows close behind a young man in a dark green bomber jacket carrying a paper bag of oranges as he weaves between food stalls, steam rising from woks, warm tungsten light reflecting on the wet stone. 8-16s: he turns into a doorway and climbs a narrow outdoor metal staircase; the camera stays behind him at shoulder height, passing laundry lines and potted plants. 16-24s: he steps out onto a rooftop strung with warm bulbs, where three friends sit around a small table; one of them waves and he lifts the bag of oranges. 24-30s: the camera keeps moving past him to the rooftop edge and rises slowly to reveal the whole city skyline glowing under a deep blue sky. Smooth gimbal movement, constant forward motion, natural colours, 35mm film look, fine grain. Sound: market chatter and sizzling woks, then footsteps on metal stairs, then laughter on the rooftop and a distant city hum. The man keeps the same face, jacket and bag throughout. No cuts, no text, no readable signs.

About Kling 3.0

Same prompt, Kling 4.0 and Kling 3.0

The wolf prompt from the top of this page, sent to both models with the same settings: 16:9, 10 seconds, 1080p.

Kling 4.0 1.128 credits/s at 1080p
Kling 3.0 0.8064 credits/s at 1080p

The shared prompt

Blue hour on a snow-covered plain, the last orange light low on the horizon behind. A lone grey wolf runs through deep powder snow toward and past the camera, filmed in slow motion with a long lens that tracks it smoothly; snow sprays from each stride and its breath shows as backlit vapour; fur is rim-lit orange against the cold blue landscape. High contrast, cold teal shadows, shallow depth of field, wildlife film look. Sound: muffled paws in snow, steady breath, wind. No people, no other animals, no text.
