Kling 4.0 Video Generator

Cinematic QualityMulti-Modal InputFast Turnaround

Kling 4.0 Pro is the next generation of Kuaishou’s Kling AI video model — more photorealistic motion than Kling 3.0, smarter multi-shot directing, more precise audio lip-sync, and longer clip generation. Native 4K output across text-to-video, image-to-video, and audio-driven generation.

Enter text, describe the content, movement... (e.g. A 3D boy skateboarding in the park.)

Simple Workflow

How It Works

Three simple steps from initial idea to polished 4K exported video

01

Choose Your Input

Draft a text prompt with camera direction and scene details, upload a reference image (start frame, end frame, or both), or share an audio URL for lip-sync-guided generation.

02

Set Duration and Aspect Ratio

Select clip length from a few seconds up to 30 seconds. Choose 16:9, 9:16, or 1:1. Output at 4K for final delivery.

03

Generate and Export

Submit your request and download a watermark-free MP4. All videos are saved to your account — revisit, remix, or share at any time.

Kling 4.0 Pro — The Next Generation

More Photorealistic. More Precisely Directed. More Accurate Audio. That's Kling 4.0 Pro.

Kling 3.0 proved that video, audio, and image generation could share a single architecture. Kling 4.0 Pro raises the bar — sharper motion physics, tighter lip-sync, smarter multi-shot continuity, and better prompt-to-video accuracy, all from the same unified platform.

Full-Sequence Spatial-Temporal Processing

Unlike frame-by-frame video generators, Kling 4.0 Pro models your entire sequence in one pass. Motion stays smooth, physically accurate, and free of the flickering artifacts common in older frame-based models — even on skin, fabric, water, and fast-moving objects.

No Frame-Level Flickering
Physically Plausible Motion

Audio Sync During Generation, Not After

Upload an audio URL, and Kling 4.0 Pro syncs lip movement, character motion, and ambient sound to your track during the core diffusion pass. Background music, footsteps, dialogue — everything aligns perfectly in a single generation step, no post-dubbing needed.

In-Pass Audio Conditioning
Precise Lip-Sync
Context-Aware Ambient Sound

Up to 9 Reference Images, First & Last Frame

Upload up to 9 reference images to build richer, more detailed scene compositions and multi-angle inputs. Use first-and-last-frame control to set your clip’s exact start and end points. Mix visual and voice references in the R2V model to maintain consistent character look and voice across your video.

Voice + Visual Reference Fusion

4K — No Upscaling, No Compromise

Kling 4.0 Pro generates at native 4K — a direct upgrade from Wan 2.7 1080P. Every pixel is rendered at full resolution for commercial-grade output, with no upscaling artifacts to ruin your final clip.

What Kling 4.0 Pro Does Better Than Kling 3.0

The same versatile platform — now sharper, longer, and more precisely controlled

More Realistic Marketing Video

Product shots and brand campaigns now render with visibly sharper character skin, clothing detail, and product surface realism than Kling 3.0 — with tighter audio lip-sync for spokesperson content.

Longer, More Coherent Multi-Shot Sequences

Kling 4.0 Pro extends Kling 3.0's 6-cut multi-shot capability with better scene continuity — character appearance and lighting stay consistent across more cuts, reducing the need for manual editing.

Better Social Content in Fewer Tries

Improved prompt adherence means your first generation is closer to what you described. More accurate motion, more natural expressions, and more reliable aspect-ratio framing across 9:16, 16:9, and 1:1.

More Precise First & Last Frame Control

The transition between your start and end frames is smoother and more physically believable in Kling 4.0 Pro — tighter motion interpolation for product reveals, fashion cuts, and narrative transitions.

      FAQs

      Frequently Asked Questions

      Everything you need to know about Kling 4.0 Pro and our platform

      What is Kling 4.0 Pro?

      Kling 4.0 Pro is the next generation of Kuaishou’s Kling AI video model — a step beyond Kling 3.0 with more photorealistic motion, more precise audio lip-sync, smarter multi-shot directing, and longer clip support. It builds on the unified multimodal architecture introduced in Kling 3.0 and refines every core capability.

      Can I try Kling 4.0 Pro for free?

      Yes. New accounts receive complimentary credits to try text-to-video, image-to-video, and audio-driven generation. No payment required to get started — create your first clip and see the quality for yourself.

      How does Kling 4.0 Pro compare to Kling 3.0?

      Kling 3.0 introduced the unified multimodal architecture — video, audio, and image generation in a single model — along with physics-accurate motion and multi-shot directing. Kling 4.0 Pro takes each of those further: sharper character and fabric detail, tighter lip-sync timing, more coherent character consistency across multi-shot cuts, and improved prompt adherence for more predictable first-generation results.

      What inputs does Kling 4.0 Pro accept?

      Kling 4.0 Pro accepts text prompts for T2V generation, single or paired reference images for first-and-last-frame I2V control, and audio for native lip-sync. All input modes work through the same unified platform with consistent billing.

      How does native audio synthesis work?

      Unlike tools that add audio in post-production, Kling generates audio during the core diffusion process. Voiceovers, dialogue, ambient sound, and music are synthesized and synchronized to motion and lip movement in a single inference pass — no separate alignment step required.

      What is first-and-last-frame control?

      First-and-last-frame control lets you set your clip’s exact start image, end image, or both. Kling 4.0 Pro generates the seamless motion between them — perfect for product reveals, cinematic transitions, and precisely controlled narrative arcs.

      What resolutions and aspect ratios are supported?

      Kling 4.0 Pro supports native 4K output across 16:9, 9:16, and 1:1 aspect ratios. Every export is a watermark-free MP4 file suitable for professional and commercial use.

      What is multi-shot directing?

      Multi-shot directing lets you define up to 6 camera cuts — shot type, perspective, and movement per segment — within a single generation prompt. Kling 4.0 Pro handles transitions automatically, enabling cinematic storytelling without manual editing.

      Do pay-as-you-go credits expire?

      No. Credits purchased via one-time top-up packages never expire. They remain in your account indefinitely — add more whenever you need them.

      What is the refund policy?

      All new subscription plans include a 7-day money-back guarantee. If you have a concern about a renewal charge, contact support within 72 hours and we will review it with you directly.
