Re: FCP X re-rendering noise correction plug-in any time I make a change

[Jeff Kirkland] "I try to get the clips that need Neat Video applied rendered to a new file as early in the edit as I can, or once I know Neat is going to do the job, I leave it to the very end of the edit to apply it."

This is what I do as well, either apply and adjust the filter then export the clip and bring it back in to replace the original, or apply the filter then turn it off until the edit is complete.

But, Michael, the problem you describe does sound out of the ordinary. After applying the filter you should be able to go right back to work editing immediately. Only seeing slow performance while the playhead is over the unrendered clip with Neat on it. have you tried trashing preferences and/or reinstalling the plug-in?
