What is KwaFlux? A local app for video, photos, and sound

What KwaFlux is

KwaFlux is a desktop app for Windows and Mac that repairs, enhances, converts, and cleans up video, photos, and audio on your own GPU. One workspace covers upscaling, old-footage restoration, cutout, color and motion, beauty, audio cleanup, subtitles, file repair, and format conversion, from import to export, without uploading your media.

• One desktop app for the enhancement pipeline from import to export
• Runs on your local GPU — no cloud upload, no per-minute billing
• Built for real client batches, not only demo reels

Local-first by design

• Large masters stay on disk — no 50 GB round-trip to a data center
• NDA / client footage stays on the workstation
• What stays local and what still uses the network: local vs cloud processing

Who it is for

• Editors and colorists closing the gap on almost-usable footage
• Archivists digitizing tapes and film scans
• Teams who already have an NLE and need a station between ingest and grade

Try it yourself

• Download: installers for Windows and Mac, with the current system requirements
