In order to achieve a rot spot free transfer, there is an AVIsynth filter called "TOOT" that will check three separate sources of video pixel by pixel and average the two most similar. So, for instance if I make three captures from three different ANH LD's and on one frame one has a rot spot and the other two don't, the output video will be without that spot. Using this method, I should be able to produce a transfer that is rid of all rot spots
This is what I'm talking about. What is a rot spot visually? I take it they are a product of the actual LD. Are they due to wear er what?
