How to denoise video with AI without plastic faces

Digital sensor noise, compression mosquito noise, and analog film grain fail differently. Aggressive denoise that erases grain can also erase skin texture. Start by naming the noise you actually have.

• Low-light CMOS noise → denoise + optional night upscale
• Heavy film grain → film-grain models, not photographic wipe
• Streaming compression → reconstruct detail after mild denoise

1. Import the clip and preview a noisy segment
2. Apply denoise at a moderate strength first
3. Add restoration or upscale only if detail is still soft
4. Export once — avoid stacking five online tools

In KwaFlux, free 1s/3s/5s previews let you compare strengths before a full GPU render. Nothing uploads.

AI cannot invent photons that never hit the sensor. Extreme ISO mush improves, but it will not become a clean daylight plate. If motion blur is the real problem, denoise will not fix it — see how to fix blurry video.
