General model
Balanced detail recovery for everyday camera footage, screen recordings, and compressed exports.
Kwaflux feature
AI video upscaler that recovers real detail — locally
Kwaflux upscales low-resolution video to 1080p or 4K using neural super-resolution models that reconstruct texture and edges — not the smeared, plastic look of simple interpolation. Everything runs on your own GPU, so nothing is uploaded.
- Upscale 480p / 720p sources to 1080p or 4K output
- Dedicated models for general footage, portraits, anime, and night scenes
- 100% local processing — no upload, no per-minute cloud fees

Upscaling models built for specific footage
Portrait model
Face-aware reconstruction that keeps skin texture natural instead of over-smoothing people.
Anime model
Line-art aware upscaling that keeps edges crisp and flat colors clean on animated content.
Night-scene model
Tuned for dark, high-noise footage where generic upscalers amplify grain into artifacts.
Multiple quality tiers
Each model ships with selectable strength tiers, so you can trade processing time against output quality per project.
What AI upscaling actually recovers
Traditional resizing spreads existing pixels over a larger frame — the result is bigger, but not sharper. A neural video upscaler is different: it has learned what real-world texture, hair, fabric, text, and edges look like, and reconstructs plausible detail that the original compression threw away. That is why AI upscaling from 720p to 4K can look dramatically better than a player's built-in scaling.
An honest note on limits: AI cannot invent information that was never there. A heavily degraded sub-480p source will improve, but it will not become true native 4K. The best results come from 720p/1080p sources with reasonable bitrates — which covers most real-world archives, screen recordings, and social exports.
Why local processing matters for upscaling
Cloud upscalers charge by the minute and require uploading full-resolution masters — slow for large files and a non-starter for confidential client work. Kwaflux runs the entire pipeline on your own GPU: no upload time, no queue, no per-job billing, and footage that never leaves your machine.
How to upscale a video with Kwaflux
Import your source
Drag the video into Kwaflux. Low-resolution, compressed, and noisy sources are exactly what the pipeline is built for.
Pick a model and output size
Choose general, portrait, anime, or night-scene, select 1080p or 4K output, and preview a 1s/3s segment to compare settings before committing.
Export
Render the full clip on your GPU and export. Batch processing handles whole folders when you need to upscale a series.
System requirements
GPU
DirectX 12 compatible discrete GPU (NVIDIA / AMD / Intel Arc)
NVIDIA RTX recommended for the best performance via TensorRT acceleration.
Memory
16 GB RAM or above
Keeps previews and export staging responsive under load.
Storage
Fast SSD workspace
Better for caching, temp artifacts, and larger preview sessions.
Windows 10/11 (64-bit) supported today; macOS is in development.
Frequently asked questions
What's the difference between upscaling and enhancing?
Upscaling increases resolution (for example 720p to 4K) while reconstructing detail. Enhancing improves qualities other than resolution — color, dynamic range, frame rate, or stability. Kwaflux includes both, and they can be combined in one workflow.
Can AI really turn 480p into 4K?
It can render a 4K frame from a 480p source, and it will look substantially better than player scaling — but it cannot recover information that never existed. Expect a clean, watchable result rather than true native-4K detail. From 720p or 1080p sources, results are much closer to native.
Which upscaling model should I use?
Use the portrait model when people are the subject, the anime model for animated content, the night-scene model for dark and noisy footage, and the general model for everything else. The 1s/3s preview makes it fast to compare models on your actual footage.
Do I need an NVIDIA GPU?
No. Kwaflux runs on any DirectX 12 compatible discrete GPU — NVIDIA, AMD, and Intel Arc are all supported. NVIDIA RTX cards get the best performance through TensorRT acceleration.
Is my footage uploaded to the cloud?
No. Kwaflux processes everything on your own machine — nothing is uploaded, there is no queue, and your media never leaves your computer.
Can I try it before buying?
Yes. Download Kwaflux and render 1-second and 3-second effect previews across all AI modules without creating an account. A free account plus a paid plan unlocks 5-second previews and full export, and there is a $199.99 lifetime license if you prefer to skip subscriptions.
