Why generate it here instead of going direct?

You could go straight to Kling. Then you'd need a second subscription for Wan 3.0, a third for Kling O3, and a fourth for image generation.

Most real projects use more than one model — you draft on something fast and cheap, then finish on something expensive. Plurel puts eight video models and four image models on a single balance, so you switch models instead of switching accounts.

  • One balance, every model.
  • No subscription required. Credits don't expire.
  • Nothing to install. No API keys, no waitlist.
  • Everything else included — images, upscaling, background removal, headshots and PDFs draw on the same credits.

What is Kling 4.0?

Kling 4.0 is the newest video model from Kling AI, Kuaishou's generative video platform, released on October 15, 2026. It generates 3 to 30 seconds in a single pass at 720p or 1080p, with two-channel stereo sound — speech with tighter lip sync, effects, ambience and music — made together with the picture. It keeps fast action, tracking shots and orbiting cameras steady, and follows long, timed prompts beat by beat, so a 30-second clip can carry a whole scene instead of a single moment. You can start from words alone, pin the opening and closing frames so a character or product stays exactly as designed, or hand it a clip whose camera movement and pacing it should follow. On Plurel you can use Kling 4.0 instantly with no API key or separate subscription.

What Kling 4.0 Can Create

Up to 30 seconds in one take

Anything from 3 to 30 seconds per generation — room for a scene to build and land without stitching clips together.

Sound made with the picture

Two-channel stereo dialogue, effects, ambience and music generated in sync, with tighter lip sync for speaking characters.

Steady fast motion

High-speed action, tracking shots, orbits and complex camera moves stay smooth and coherent instead of smearing.

Start and end on your frames

Give it the first frame, the last frame or both and it works out the motion in between — the way to keep a character or product exactly as designed.

Follow a reference clip

Upload a clip and Kling 4.0 takes its camera movement and pacing, then rebuilds the shot with what your prompt and picture describe.

Long, directed prompts

Up to 8,000 characters: timed beats, shot lists, camera notes and sound cues are followed in order.

Kling 4.0 Key Features

3–30 seconds

3, 5, 8, 10, 15, 20 or 30 seconds; 5 by default.

720p or 1080p

720p for drafts and social posts, 1080p for delivery.

Four aspect ratios

16:9, 9:16, 1:1 and 21:9 ultrawide. With a start frame the clip keeps the picture's shape; with a clip, auto follows it.

Text, frames or a clip in

A prompt alone; a start frame, an end frame or both; or a reference clip with an optional picture.

Stereo sound on every clip

Sound is always generated — dialogue, effects and music come with the video.

Per-second pricing

6.5 credits a second at 720p, 9.5 at 1080p. With a reference clip, 4 or 5.5 a second on the video plus the clip, the clip counted as at least as long as the video.

What a Kling 4.0 video costs

One Kling 4.0 generation is 32.5 credits.

$7.99

100 credits

Three 5-second 720p clips — or one 15-second scene.

$14.99/mo

300 credits every month

Nine 5-second 720p clips a month, or one 30-second scene at 1080p. Credits roll over.

Every account includes chat and pictures that refill every 5 hours; video uses credits.

Stereo sound, made with the picture

Kling 4.0 generates the soundtrack in the same pass as the video, so voices, effects and music land on the action instead of being laid over it afterwards.

Dialogue with tighter lip sync for speaking characters

Effects and ambience timed to what moves on screen

Two-channel stereo on every clip

Kling 4.0 Prompt Ideas to Get You Started

🎙️ Talking to camera

A barista in a sunlit corner café leans on the counter and says to camera, warmly: "First coffee's on me — just don't tell my boss." She laughs and slides a cup forward. Espresso machine hiss, quiet chatter, soft daylight. 8 seconds, 9:16.

🚴 One long tracking shot

One unbroken tracking shot beside a cyclist racing downhill through a coastal town at dawn: past fish stalls, under washing lines, around a fountain, then out onto the cliff road as the sea opens up below. Freewheel ticking, gulls, rushing wind. 20 seconds, 16:9.

🧸 Clay stop-motion

Handmade clay stop-motion: a tiny knitted fox in a yellow raincoat waters a single flower on a windowsill during a storm, and the flower grows into a tree that fills the room. Visible fingerprints, stepped 12 fps motion, warm lamp light, gentle ukulele. 10 seconds, 1:1.

🏺 From first frame to last

Open exactly on the start frame and end exactly on the end frame. In between, a potter's wet hands centre a lump of clay on the wheel, pull it up into a tall vase and smooth the rim. Close-ups, the hum of the wheel, soft studio light. 10 seconds.

🍜 Timed multi-shot scene

0–4 s: wide shot of a night market in the rain, neon reflected in the puddles. 4–8 s: close-up as a street cook flips noodles in a flaming wok. 8–12 s: a girl in a yellow raincoat takes the bowl and grins at the camera. Sizzle, rain, chatter. 12 seconds, 16:9.

🎥 Borrow a clip's camera

Follow the camera movement and pacing of the uploaded clip, but replace the scene: a red vintage convertible drifting along a mountain road at golden hour, dust trailing behind it. Engine roar and tyre squeal. 10 seconds.
