I think a long time ago before the server crashed the last time, there were pictures in post that showed some of the common errors in analog captures. One I am specifically interested in is blotches of color on white text. In specific, when I see the credits roll on one of my movies, you can see tiny flashes of blue and I think other colors in the text. I kind of figured that was chromashift but I also have a commercial DVD that does the same thing. What is that?
