Did you edit each frame for the entire movie, i’m imagining something like photoshop’s content aware fix tool?
I did only the first 1m45s or thereabouts, and my method was relatively primitive so definitely not the entire movie. (I don’t even know what that tool you mentioned is! 😃) Much of it was copying bits from the right or left of the problem spot to do patching, or when I was lucky (no gradients, grain, detail, etc. to worry about) I could just do airbrushing. But there were a number of spots with zooms where I had to re-size patches. Ugh to those cases and how long they take! (But they do look good when done.) I wish I had super software to make it easier, but I don’t. (My photoshop is old…but it gets the job done)
Largely what I did was stuff that most regular paint programs do: just load in a frame (image file), deal with the bad spot, save it…over and over and over…then eventually connect all the frames back together in an avi.
Beyond that damaged section (the in opening), Octorox’s up-scaled version looks GREAT! I’d almost say that any ten seconds of the part I worked on has as many blemishes as the whole rest of the movie combined, it looks that good/clean.
