Why Create With Kling 4.0 on Ricebowl
Feature 01
30-Second Single-Take VideoTwice the Length of Kling 3
Kling 4.0 renders a single take of 3 to 30 seconds. Kling 3 stopped at 15, so anything longer had to be two clips cut together, and the seam usually showed in the face, the light or the camera path. With Kling 4 the whole shot comes out of one pass: the character keeps the same face from the first frame to the last, the lighting holds, and a slow push-in can run the full half minute without a restart. Thirty seconds is the length of a classic TV spot, a complete product walkthrough or a short scene with a beginning, a middle and an end. Plan the take like a real shot: where the camera starts, what changes in the middle, and what the final frame should hold. For most social ads 10 to 20 seconds is plenty; reach for the full 30 when the story needs the room.
- Kling 4.0 renders 3 to 30 seconds in one take
- Twice the 15-second ceiling of Kling 3
- No stitching seams between clips
- Long enough for a full ad or scene
Feature 02
Up to 10 Keyframes Per VideoPlot the Story Frame by Frame
Kling 3 gave you a first frame and a last frame. Kling 4.0 accepts up to 10 keyframes, plus separate start and end frame control, so you can pin the moments that matter and let the model animate everything in between. Upload a storyboard of stills, put them in order, and Kling 4 moves the camera and the characters from one beat to the next. This is the feature that turns a prompt into a directed sequence: the hero enters on frame one, turns on frame four, picks up the product on frame seven and looks into the lens on frame ten. Keep neighbouring keyframes close in pose and framing so the transitions stay smooth, and describe the motion between them in the prompt.
- Up to 10 keyframes in one Kling 4 video
- Start and end frame control on top
- Storyboard stills become one sequence
- The prompt describes motion between beats
Feature 03
15 References for Consistent CharactersImages, Clips, Saved Subjects and Voice
Kling 4.0 takes up to 15 reference files in one request: up to 10 images, up to 5 video clips with a combined length of 30 seconds, up to 7 saved characters or objects, and a voice sample. That is how you keep the same actor, the same outfit and the same product across every shot of a campaign. Load the product from three angles, the model’s face, the logo and a clip of the camera move you want, then describe the scene. Kling 4 treats the references as the source of truth for identity and uses the prompt for action. For brand work, save your hero product and your main character once and reuse them in every Kling 4 video.
- Up to 15 reference files per request
- 10 images, 5 clips, 7 saved subjects
- Voice sample for a consistent speaker
- Same face and product across a campaign
Feature 04
4K Output and 10-Bit HDRDetail That Holds on a Big Screen
The full Kling 4.0 model outputs 720p, 1080p or 4K, and Kuaishou lists 10-bit HDR as its next addition. HDR matters most in scenes with a wide range of light: neon signs at night, a window behind a subject, sunlight on chrome. In 8-bit video those highlights clip to flat white and the shadows band; 10-bit keeps the gradient. Choose 4K when the clip is going on a large display, into an edit that will be cropped, or into a product page where people zoom. For quick drafts and social previews, 720p renders faster and costs less. Kling 4.0 Flash, the lighter version, is 720p only with standard dynamic range.
- Kling 4.0 outputs 720p, 1080p or 4K
- 10-bit HDR listed as coming soon
- Highlights and shadows keep their gradient
- Flash version is 720p and SDR
Feature 05
Stereo Audio, Lip Sync and AccentsDialogue That Matches the Mouth
Kling 4.0 generates the soundtrack in the same pass as the picture: stereo ambience, sound effects and spoken lines. Lip sync is tighter than in Kling 3, and you can ask for a specific accent, so a British shop owner sounds British and a Texan rancher sounds Texan. Put dialogue in quotes, name the speaker and the accent, and describe the room so the reverb fits. Stereo placement follows the camera: a car passing left to right moves across the speakers. For ads with voice-over, keep lines short and one idea per sentence; Kling 4 times the mouth to each word, so fewer words means cleaner delivery.
- Stereo sound generated with the picture
- Tighter lip sync than Kling 3
- Request a specific accent per speaker
- Sound placement follows the camera
Feature 06
21:9 Widescreen and 8,000-Token PromptsWrite the Whole Shot List
Kling 4.0 adds a 21:9 cinema aspect ratio next to 16:9, 9:16 and 1:1, and accepts prompts up to 8,000 tokens. The long prompt window means you can write a real shot list: timing for each beat, the lens, the lighting, what every character wears and says, and the sound under it all, without trimming. The widescreen frame suits trailers, music videos and establishing shots where the landscape carries the mood. Kuaishou has also announced video extension up to two minutes as a coming feature, which will let you continue a Kling 4 take instead of starting over.
- New 21:9 cinema aspect ratio
- Prompts up to 8,000 tokens
- Room for timing, lens, wardrobe and sound
- Extension to 2 minutes announced
PROMPT EXAMPLES
Kling 4 Prompts
Prompt
0-8s: slow drone push toward a lighthouse on a cliff at dawn, waves breaking below. 8-20s: inside, a keeper in a wool sweater climbs the spiral stairs, lantern in hand. 20-30s: at the top he lights the lamp and the beam sweeps across the sea. Wind, gulls, the creak of the stairs.
Prompt
Keyframe story, 10 frames: a girl finds a paper boat on a rainy street, carries it home, dries it by the heater, draws a face on it, and sets it sailing in the bath. Keep her yellow raincoat and the boat identical in every frame.
Prompt
Medium shot, a London bakery at 7 a.m. The owner, a woman in her fifties with a flour-dusted apron, slides a tray of croissants onto the counter and says in a warm British accent: "First batch is always the best one." Oven hum, a bell on the door.
Prompt
21:9 widescreen, golden hour, a lone rider on horseback crosses a vast salt flat toward distant mountains, the camera tracking alongside at a low angle, dust trailing in the light. Hooves, wind, a low cello note.

VERSIONS
Kling 4.0 vs Kling 3.0: Should You Switch
Switch for length, keyframes and references. Stay on Kling 3 for short clips you already know how to prompt.
Length: 30 seconds against 15
Kling 4.0 doubles the longest single take. Anything between 15 and 30 seconds no longer needs to be cut from two clips.
Control: 10 keyframes against 2
Kling 3 anchors the first and last frame. Kling 4 lets you pin up to ten moments in between, which is the difference between a shot and a sequence.
Consistency: 15 references against 2
Images, clips, saved subjects and a voice sample in one request keep a character and a product the same from shot to shot.
OUR TAKE
Our Verdict on Kling 4.0
Choose Kling 4.0 for anything longer than 15 seconds or anything with a storyboard
The two numbers that matter are 30 seconds and 10 keyframes. If your idea fits in one 15-second shot with a clear start and end, Kling 3 already does it. If it needs a longer take, several planned beats or the same character across many shots, Kling 4 is the upgrade.
Kling 4.0 Flash is for drafts, not finals
Flash tops out at 720p and 20 seconds with standard dynamic range. Use it to test an opening, a camera move or a line of dialogue quickly, then render the keeper on the full Kling 4.0 model.
The reference system is the real reason brands will switch
Fifteen references with saved characters and objects means a product and a face can stay identical across a whole campaign. That consistency is harder to get from any single prompt, and it is where Kling 4 saves the most rework.

FAQs

Create a Kling 4.0 VideoWhen is the Kling 4.0 release date?
Kuaishou announced Kling 4.0 on September 27, 2026, with the full model rolling out in October. The lighter Kling 4.0 Flash opened to top-tier Kling members on September 28.
What's new in Kling 4 compared with Kling 3?
The longest single take doubles from 15 to 30 seconds, frame control grows from a start and end frame to up to 10 keyframes, references grow from 2 images to 15 files including clips and saved subjects, and audio moves to stereo with tighter lip sync. Kling 4 also adds a 21:9 aspect ratio and 8,000-token prompts.
What is the difference between Kling 4.0 and Kling 4.0 Flash?
Kling 4.0 renders up to 30 seconds at up to 4K, with 10-bit HDR on the way. Kling 4.0 Flash renders up to 20 seconds at 720p in standard dynamic range. Flash is for fast drafts; the full model is for finals.
How long can a Kling 4 video be?
A single Kling 4.0 take runs from 3 to 30 seconds; Flash stops at 20. Kuaishou has also announced video extension up to two minutes as a coming feature.
Is "Kling 4K" the same as Kling 4?
No. 4K is a resolution and Kling 3 already offered it. Kling 4.0 is the new model version, which also outputs 4K.
How much does Kling 4.0 cost?
On Ricebowl every Kling 4.0 video is paid with credits, and the price depends on length and resolution. New accounts get 20 free credits. See the pricing page for current credit packs.
Is there a Kling 4 API?

Is there a Kling 4 app or APK?
Kuaishou’s own Kling app is available from the official Kling website and app stores. Ricebowl runs in the browser on desktop and mobile, so there is nothing to install.
What can I make with Kling 4.0?
Kling 4.0 suits anything that needs a longer take or a consistent cast: short drama scenes, product walkthroughs, ad campaigns with the same model in every cut, dialogue with lip sync, and widescreen trailers.
How do I write a good Kling 4 prompt?
Write it as a timeline: what happens from 0 to 8 seconds, from 8 to 20, and so on. Name the lens and light, put dialogue in quotes with the speaker and accent, and list the sounds. Use references for identity and the prompt for action.
