Restoration tools are very cool. One tool I liked allows you to draw a marquee around an area you'd like to fix. It then allows you to shift the frames forward/back in just the highlighted area to find a frame without the blemish. Obviously a more static shot gave better results, but it was fast and easy to use. Much easier than trying to use a blemish/clone tool. Doing the same fix with rotoscoping techniques would take much more time/effort.
