I dunno what window line you are referring to, titanic, there are many lines that are ghost images.
But now that you mention it the vertical seam on the back of her dress loses its top and bottom edge and the knot in her apron becomes a bit less distinct. Unfortunately those details are pretty hard to make out before the filtering and in motion are probably invisible.
Do you plan to attempt your own clean up, titanic, or do you figure to watch it completely unfiltered?
