I have little experience with Motion, but basically what I am seeking to accomplish is to take a shot that I have panning across the front of a movie theater sign showing the current movies that are out, and edit that shot with my own custom title so that the theater sign shows different text that I put in. Now, if I simply overlaid a title then some of the original words beneath might still show, so I'm thinking I might fit a generator over the original text and motion track it with the custom title on top of it, so there would be two layers, both motion tracked. I found some help pages on this subject from Apple but would like some feedback from fellow users/editors detailing how to go about this process. Motion 5 and FCP X here. Thanks for any suggestions & info.
