Vegas Masking Issue

[Pikapwn]

In Vegas my masks seem to be off in certain portions of clips.


The mask in the left window is for the middle finger of his right hand. Where the mask is clearly past the edge of his finger in the masking window, in the preview it appears to be right on the edge. When I make the mask right on the edge, it cuts into his finger.
Does anyone know why this is happening?

This is probably a better question for the Sony Vegas section in the Video Editing Software part of the help forums.

Ok, thanks. I just posted there.
