I played with the Neat Video plug-in for PrPro and had a strange occurrence. After applying the settings in the Neat Video Panel, it did not keep my trim points. After some research, found out you need to Clip>Nest before applying the plug-in.
Found this list of known errors and hopefully will save someone else the time. The plug-in does a fantastic job on noise removal!
