Sharpen pushes the two sides of each edge apart in brightness, like an unsharp mask.
Parameters
| Name | What it does | Default / range |
|---|---|---|
| Amount | How strongly edges are pushed apart. 100% doubles the local contrast. | 50, 0–500 |
| Radius | Width of the edges it works on, in pixels. Small for fine detail, large for local contrast. | 1.5, 0.1–100 |
| Threshold | Leaves differences smaller than this alone, so flat areas and grain don't get sharpened. | 0%, 0–100% |
Tips
- A large Radius with a modest Amount gives a local-contrast "punch" rather than crisp detail.
- Raise Threshold on noisy footage to keep the grain from getting louder.
