Denoise AI – FabCloud is live. Remove noise in the cloud, no GPU. 30% OFF for launch.
Learn more >Sensor grain, ISO speckle, compression blockiness, frame flicker, and low-light haze can reduce footage quality. UniFab Denoise AI uses deep-learning models on your PC to reduce noise through a guided workflow while preserving visible detail.
Free trial with full features, no watermark.
Noise reduction can blur edges, micro-textures, and skin detail along with unwanted grain. UniFab Denoise AI analyzes video frame by frame to reduce noise while preserving sharpness, color depth, and natural detail.

Grain, color noise, low-light haze and compression speckle look different and come from different sources. Denoise AI treats them frame by frame; blocky compression damage belongs to VideoRefiner AI.
| Noise type | What it looks like | Typical footage | What Denoise AI does | Limits |
|---|---|---|---|---|
| Grain and ISO speckle | Fine, moving speckles across the whole frame | High-ISO nature, wildlife and landscape shots | Reduces grain frame by frame while keeping fur, eye reflections and leaf textures | Resolution stays the same; pair with Video Upscaler AI for sharper output |
| Chroma (color) noise | Colored blotches in shadows and flat areas | Dim indoor scenes, night cityscapes | Removes color and luminance noise and restores color and shadow detail | Cannot invent color that the camera never captured |
| Low-light noise and haze | Heavy luma grain and muddy, lifted shadows | Night sky, aurora, indoor lighting | Analyzes each frame’s noise pattern and restores edges without an over-smoothed look | Noise reduction only; it is not a deblur or sharpening tool |
| Compression speckle | Blockiness and speckle left by re-encoding | Older downloads, budget-camera and drone files | Reduces light compression speckle and artifacts from these sources | Heavy blocky squares are a job for UniFab VideoRefiner AI |
Denoise AI – FabCloud runs the same Silens model in Fast and Standard modes, so you can denoise without a local GPU.
4.0 FabCloud (new)
Denoise AI - FabCloud lets you process video denoising entirely in the cloud. Powered by the same Silens model in Fast and Standard modes.
3.0 Faster processing
This update ships dedicated AI plugin support for NVIDIA 50 Series GPUs, so RTX 5080 / 5090 owners hit faster denoise video processing right out of the gate. Measurably ahead of typical CPU-only or cloud-based denoisers.
2.0 Inference engine upgrade
The upgraded inference engine delivers 60-100% faster video noise reduction on supported GPUs, cutting wait time on long 4K and 8K clips.
| Scene | Improves | Won't fix |
|---|---|---|
| Low-light and night footage | Luma grain, color noise, muddy shadows and soft edges | Blur from camera shake or a slow shutter; resolution stays the same |
| Old recordings and home videos | Grain and speckle while keeping skin, hair and texture detail | Blocky compression squares (VideoRefiner AI) and low resolution (Video Upscaler AI) |
| Phone, drone and action-camera clips | High-ISO grain and color noise from small sensors, with color correction | Detail lost to digital zoom; use Video Upscaler AI to raise resolution |
| Screen recordings and downloads | Light compression speckle and sensor-style noise | Heavy blocky artifacts and smudged text, which VideoRefiner AI targets |
Noise reduction, compression repair and resolution upscaling are three different jobs, each with its own product.
| UniFab Denoise AI | UniFab VideoRefiner AI | UniFab Video Upscaler AI | |
|---|---|---|---|
| The problem | Grain, ISO speckle, color noise, low-light haze | Blocky compression squares, smudged detail, local blur | Low resolution: SD, 720p or 1080p that needs 4K, 8K or 16K |
| What changes | Noise is removed; resolution and framing stay the same | Compression damage is reconstructed at the current resolution | Resolution increases with AI-restored detail |
| Typical source | High-ISO, night, drone and budget-camera footage | Streamed, downloaded and heavily re-encoded video | Old movies, TV recordings, anime and home footage |
| Processing | Local GPU or Denoise AI – FabCloud | Local GPU or VideoRefiner AI – FabCloud | Local GPU or Video Upscaler AI – FabCloud |

FabCloud is the unified cloud processing service powering all Fab brands, including UniFab, BookFab, DVDFab, and more. It enables high-performance AI processing without depending on your local hardware. Learn more. By purchasing FabCloud Credits, you can use all AI-powered cloud features across both the web and desktop applications.
Look for frame-by-frame noise reduction, detail preservation, support for high-resolution footage, and hardware acceleration. UniFab Denoise AI processes video locally on a supported PC and can reduce noise in low-light, high-ISO, 4K, and 8K footage.
To clean grainy or noisy footage, use software with AI grain removal or AI video denoising. These tools analyze each frame, reduce unwanted artifacts, and improve clarity while preserving visible texture.
For video noise reduction, the recommended configuration includes
Windows 10 or 11 (64-bit only);
16GB RAM or more; and
an NVIDIA RTX 30 series or later graphics card with 8GB VRAM.
Yes. UniFab Denoise AI analyzes video frame by frame to reduce grain while preserving visible texture, so the result can look cleaner without the soft appearance caused by basic blur filters.
Free online denoisers may impose clip, file-size, or compression limits. UniFab Denoise AI offers local GPU processing for supported 4K and 8K footage, so you can choose a desktop workflow instead of uploading video to an online service.
Denoise AI starts with a 30-day free trial with full features and no watermark. To keep using it, choose a monthly, one-year or lifetime license for the single module, or get it as part of Video Enhancer Pro or UniFab All-In-One.
Denoise AI removes sensor grain, ISO speckle and color noise while preserving detail. VideoRefiner AI reconstructs detail destroyed by heavy compression, such as blocky squares and smudged areas. If your video looks grainy, start with Denoise AI; if it looks blocky or pixelated, use VideoRefiner AI.
Yes. Denoise AI – FabCloud processes your video in the cloud with the same Silens model in Fast and Standard modes, so no local GPU is required. For local processing we recommend an NVIDIA RTX 30 series or later graphics card with 8 GB VRAM.
