Roto - Where do you put the edge!?

A new version of PxF_VectorEdgeBlur makes adjusting the edge much easier compared to the method shown in this video. More details here:    • PxF_VectorEdgeBlur 2.0   Where should you put the roto edge when there's motion blur? Inside? Outside? In the middle? Also, what is the proper way to edge extend when the background is polluting the transparent edges? This video is a reply to Carlos at RTC Roto Labs.
