I opened an old project that I need to tweak and one of the filters I used was Gaussian Sharpen. Premiere Pro CS3 alerted me on import that it couldn't find the plugin.

Has anyone else noticed if this plugin is missing? Previous versions of Premiere Pro seem to have both "Sharpen" and "Gaussian Sharpen". And now CS3 only seems to have "Sharpen".

The only Gaussian effect under the Blur & Sharpen folder is "Gaussian Blur".

Anyone have any idea how I can get this effect back? Would I have to install Premiere Pro 2.0 and copy over a file into the CS3 folder?

As far as I can tell, what they took out is just no longer available. Find another way to accomplish the task.
