I had this filter set as a default video effect until I noticed that my images were haloing and way over sharpened. That's when I realized that I can't leave it in there as a default since it sharpens every time. Two renders thru this filter and the output is ruined.
If 0 is even bit too much I do a simple composition with the Sharpen FX applied on the event on track one and the copied event without FX in track two. Track's Level slider then helps adjusting the Sharpen FX in smaller ranges.
