I started also to work to scene cleaning, desert storm, in particular: it’s really difficult to get rid of all those big scratches without losing details… I must find the right compromise, not an easy task. Treadwell is worst, the first shot is really hard; but I guess it could be easy to reuse previous/next frames (or part of them) to remove residual dirt. Now, if someone has cleaned some deleted scenes, and would like to share them, it will be a great help for the project!
