SDR → HDR conversion
Expands dynamic range from standard footage so highlights and shadows read the way modern displays expect.
Kwaflux feature
AI video enhancer for color, dynamic range, and motion
Beyond resolution, video quality lives in color and motion. Kwaflux enhances flat, washed-out footage with SDR-to-HDR color processing and turns choppy clips smooth with AI frame interpolation — all rendered locally on your GPU.
- SDR-to-HDR conversion, smart color enhancement, and filter grading
- Frame interpolation: 2x, 4x, or a custom 30–120fps target
- Slow motion up to 8x from ordinary frame rates

What the enhancement modules do
Smart color enhancement
Content-aware color correction that fixes dull or shifted tones without hand-tuning curves.
Filter color grading
Apply consistent, preset-driven grades across clips for a deliberate, finished look.
Frame interpolation (2x / 4x / custom)
AI-generated intermediate frames raise 24/30fps footage to any target between 30 and 120fps.
Slow motion up to 8x
Interpolated slow motion turns ordinary footage into smooth slow-mo without a high-speed camera.
When to enhance instead of (or as well as) upscale
Plenty of footage is already high-resolution but still looks wrong: washed-out color from a flat picture profile, judder from low frame rates, or dull dynamic range on modern HDR displays. Enhancement targets those problems directly. Because Kwaflux is one pipeline, you can chain enhancement after upscaling in a single pass — restore resolution first, then fix color and motion.
Frame interpolation deserves a caveat: AI-generated frames work best on natural motion. Extremely fast action or hard scene cuts can produce visible artifacts, which is why previewing a short segment first is the recommended workflow.
Why local processing matters
Color work and interpolation are iterative — you try a setting, compare, adjust. That loop is painful when every attempt means re-uploading to a cloud service. Locally, previews render in seconds on your own GPU and the iteration cost is zero.
How to enhance a video with Kwaflux
Import and diagnose
Load the clip and decide what is actually wrong: color, dynamic range, frame rate, or several at once.
Stack the right passes
Enable SDR-to-HDR or smart color for tone problems, and set frame interpolation to 2x, 4x, or a custom fps target for motion problems. Preview a 1s/3s segment to verify.
Export once
All enabled passes render in one local export — no juggling separate tools for color and motion.
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 does SDR to HDR conversion actually do?
It remaps the tone and color of standard-dynamic-range footage to take advantage of the wider brightness and color range of HDR-capable displays, making highlights brighter and shadows deeper without crushing detail.
Can I convert 30fps video to 60fps or 120fps?
Yes. Frame interpolation supports fixed 2x and 4x modes plus a custom target anywhere from 30 to 120fps. AI generates the intermediate frames, so motion looks smooth rather than duplicated.
How does slow motion work without a high-speed camera?
Kwaflux interpolates new frames between the originals and then plays them back at normal speed — up to 8x slow motion from standard footage. Natural, continuous motion slows down best.
Will frame interpolation cause artifacts?
On most real-world footage, no. Very fast motion, flashing lights, or hard cuts can confuse any interpolation model, which is why Kwaflux lets you preview a short segment before rendering the full clip.
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.
