Quick progress report... I've finished my first pass of patches on reel 1. That involved using different types of smoothing on different scenes. It was very tedious and I will need to do the same for the other two reels. I also have a second pass of some miscellaneous border corrections - should be a lot quicker than the first set of corrections, though.
So progress is being made. Once those are all done, it'll be ready to encode.
