I just read on the Neat Video form the following which I was not aware of and figured this one would be an easy one for others to miss.
"Yes, using a small version of the frame is NOT acceptable for many reasons. One of them is that the noise properties of the normal frame and small version of the frame are absolutely different, so a noise profile built using a small version will not be right for processing the normal frame.
Therefore, please use the "Best (Full)" setting in Vegas viewer to build a profile and preview NV filtration. Otherwise, Vegas will send small versions of the frame to the NV plug-in and that is not what you want and not what NV expects."
