Sorry if I wasn’t clear. What I am talking about is the following: I have a scanned letter from a soldier to his wife from World War 2. I have an actor’s voice reading the letter and I am using the letter itself as the video. Traditionally I have seen this treated as a move on the letter image with the line that is actually being read slightly brighter. I know I can do this with a feathered mask. I think this has become somewhat of the standard treatment for this type of thing and was hoping someone out there might have seen this done differently from a creative perspective. I know this is all a bit vague and perhaps a mask has been done so much because it is the best way to do it. I should probably look at some CSI episodes to see if they ever had to do this.
