Kling 4.0 Video Generator
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.

How It Works
Three simple steps from initial idea to polished 4K exported video
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.
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.
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.
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.
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.
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.
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.
Simple, Transparent Pricing
Choose a monthly subscription or pay-as-you-go credits. No hidden fees. Apply your credits across all Kling 4.0 Pro generation modes — T2V, I2V, R2V, and Video Edit.
