## What this tool does
Remove grain and sensor noise with hqdn3d, then restore edge sharpness — clean night footage.

## Typical user problems
- Low-light phone footage and old camcorder tapes crawl with grain that eats bitrate and looks amateur. The hqdn3d 3D denoiser averages noise across space and time, then a mild unsharp pass brings back the edge definition that smoothing softened.
