The Sharpen effect allows you to make your images better focused (although it cannot substitute for an image that's properly focused in the first place). It focuses blurry images by increasing the contrast of adjacent pixels.
In the Properties Area of the Video Effect window you can change the effect propertieschange the effect properties.
The only property of the Sharpen effect available for setting is its level (the magnitude of displacement).
