AI generator workflow
Upscale Veo videos to 4K locally
Veo is often used for dialogue shots: the framing lands, but the file is soft and compressed for review. KwaFlux restores faces, clears the compression and upscales, then evens out the grade with Smart Color, all on your own computer.

§01Why
Why Veo output needs upscaling
- 01Veo is often used for dialogue scenes, and the file usually arrives at 720p to 1080p, compressed for review. Pause it and you may see blocks around hair and dark clothing.
- 02Faces carry dialogue. Smart Repair restores them while it cleans the compression and sets the output size, in one pass.
- 03Generated clips often come with a flat, safe grade. Smart Color corrects casts, flatness and exposure without sliders, which helps a shot sit next to camera footage.
- 04Dim interiors are common in dialogue work. If Smart Repair turns grain into speckle, try Night Scene in Special Scene Repair on the same preview.
§02Workflow
One timeline, from source to delivery.
Follow the playhead through each step. Every block is a module you'll find in the app, running on your own computer.

KwaFlux local path
Import the export you already have, preview free 1s/3s/5s on your GPU, then batch the keepers — no second upload meter.
Typical cloud upscale path
Re-upload the generation to another service → wait in queue → pay per minute — and the master still left your machine.
§04Steps
Three-step workflow
Export from the generator
Download the clip at the highest resolution and bitrate your plan allows — the cleaner the source, the more AI Video Enhancer can recover.
Preview settings in KwaFlux
Import the clip, apply the recommended settings below, and render a free 1s/3s/5s preview to check the result on your actual footage.
Upscale and export locally
Render to 1080p or 4K on your own computer: no upload queue and no per-clip cloud fees. For several takes, apply the same settings and use Export all.
Finish locally
Dialogue shots that cut with camera footage
Smart Repair restores faces and clears review-file compression; Smart Color then evens out a flat grade. If the clip has a dialogue track, AI Audio Denoise can clean hiss and room echo.

§06FAQ
Frequently asked questions
- What resolution does Veo output?
- Usually 720p to 1080p, depending on access tier and settings. Check the export's properties, then set the output resolution to match your timeline.
- Can KwaFlux help Veo shots cut with camera footage?
- It gets them closer. Smart Repair brings sharpness and size in line with the timeline, and Smart Color evens out the grade. The final match still happens in your editor.
- Can KwaFlux clean or change the dialogue?
- It can clean it: AI Audio Denoise removes noise and reverb from the track you have. It does not transcribe, translate or dub speech.
- Can I upscale a whole batch of generations at once?
- Yes. Load several clips into one workspace, set the parameters on one and apply them to the rest, then Export all. Each clip goes to Task Center and renders on your computer while you do something else.
- Is my generated video uploaded anywhere?
- No. The AI processing runs on your own GPU, and your clips are not uploaded for processing — there are no per-minute cloud fees or upload queues. KwaFlux still goes online for sign-in and license checks, app updates and model downloads (plus the GPU Acceleration Component on Mac), downloading a file from a link, and the crash and diagnostic reports described in our Privacy Policy.
