AI Video Upscale to 4K
Transform any low-resolution video into stunning 4K Ultra HD quality with Kling 3.0's AI-powered video upscaling technology. Whether you have old footage shot on a phone camera, compressed social media downloads, 720p screen recordings, or AI-generated clips that need a resolution boost, the Kling 3.0 video upscaler reconstructs fine details, sharpens edges, enhances textures, and reduces noise and compression artifacts — all while preserving natural motion and avoiding the artificial over-sharpening that plagues traditional upscaling methods. The AI analyzes each frame individually and in temporal context, understanding how details should appear based on surrounding frames to deliver consistent, flicker-free enhancement across the entire video. Supported input resolutions range from 360p to 1080p, with output options including 1080p Full HD, 2K, and native 4K (2160p). GPU-accelerated cloud processing means most videos complete in under 5 minutes. Start with free credits and see the difference AI upscaling makes on your very first video.
AI Video Upscale Features
Kling 3.0 delivers professional-grade video upscaling powered by state-of-the-art AI models trained on millions of high-resolution video frames. Every enhancement is designed to produce natural, artifact-free results that look like the video was originally captured at the higher resolution.
Up to 4K Output
Upscale 360p, 480p, 720p, or 1080p footage to crystal-clear 4K (2160p) Ultra HD resolution with Kling 3.0's AI video enhancer. Unlike basic bicubic or bilinear interpolation that simply stretches pixels and creates a blurry result, the AI model generates genuinely new detail information — reconstructing sharp edges, crisp text, fine textures, and subtle facial features that were lost or never captured in the original low-resolution footage. The result is video that looks natively shot at 4K resolution, suitable for large displays, professional presentations, broadcast, and any application where maximum visual clarity matters.
Detail Enhancement
Kling 3.0's AI upscaler excels at reconstructing fine visual details that are degraded or absent in low-resolution source video. Facial features become sharper and more defined — you can see individual eyelashes, skin texture, and subtle expression details that were muddy in the original. Fabric textures gain visible weave patterns and thread detail. Architectural elements show crisp brick lines, window frames, and decorative features. Text and signage in the background become readable. Natural elements like grass, leaves, and water surfaces gain realistic micro-detail. The AI draws on its training data to intelligently infer what details should be present based on visual context, producing enhancement that looks genuine rather than artificially generated.
Noise Reduction
Remove grain, compression artifacts, banding, and digital noise from your video while preserving the genuine detail underneath. Kling 3.0's AI noise reduction operates as an intelligent filter that distinguishes real visual information from unwanted noise — it does not simply blur the entire frame like traditional denoising tools. Film grain from older footage is cleaned without destroying the natural texture. JPEG and H.264 compression blocking artifacts are smoothed away. Color banding in gradients is corrected to produce smooth, natural transitions. Low-light video noise is dramatically reduced while maintaining shadow detail. The result is a clean, professional-looking video that retains all the important visual information from the original.
Fast Processing
GPU-accelerated cloud infrastructure powers Kling 3.0's video upscaling pipeline, delivering enhanced results significantly faster than desktop software or CPU-based alternatives. Most standard-length videos (under 2 minutes) complete processing in under 5 minutes regardless of your local hardware or internet speed. Longer videos scale linearly — a 10-minute clip typically processes in 15 to 20 minutes. The entire upscaling operation runs in the cloud, so you can close your browser tab and return later to download the finished result. Pro and Enterprise plan subscribers receive priority queue access for even faster turnaround during peak usage periods, ensuring your enhanced videos are ready when you need them.
How AI Video Upscale Works
Kling 3.0 makes professional video upscaling accessible to everyone. Follow these three simple steps to enhance your video resolution and quality — no technical knowledge, expensive software, or powerful hardware required.
Upload Your Video
Upload any video file in MP4, MOV, or WebM format with a maximum file size of 500MB. The AI accepts source footage at any resolution from 360p to 1080p. Low-resolution phone recordings, compressed social media downloads, screen captures, AI-generated clips, and legacy footage all work as valid input. For best results, upload the highest quality source file available — the more genuine detail present in the original, the more impressive the upscaled output will be.
Choose Target Resolution
Select your desired output resolution: 1080p Full HD for a moderate upgrade, 2K for intermediate enhancement, or 4K (2160p) Ultra HD for maximum quality. Optionally enable the noise reduction filter to clean up grain, compression artifacts, and digital noise during the upscale process. The AI automatically analyzes your source video's resolution and quality level to calibrate its enhancement model, ensuring the upscale ratio is appropriate and the output looks natural rather than over-processed.
Download Enhanced Video
Kling 3.0's AI processes every frame of your video through its neural upscaling model, reconstructing detail, enhancing sharpness, and producing a polished, high-resolution output. Processing typically takes 2 to 5 minutes for standard clips. Once complete, preview the enhanced result side by side with the original directly in your browser, then download the finished video in MP4 format at your selected resolution. The enhanced video is yours to use for any purpose — social media, client work, presentations, or personal archives.
