Do you know JavaScript, VisualBasic or C#? You will need these skills for scripting. You could buy Ultimate S Pro or Excalibur, both have the ability to add an FX to selected events and a whole lot more. (Thank you for purchasing Celluloid by the way) You could also move those events to an empty track and apply the Sharpen FX to the new track without needing a script.

Or... you could use this script which I've created for you to do exactly this task. ;-)
