Thanks for the link. I downloaded and installed the trial version. After playing around I didn’t get the mask to move with the object. I read a lot of their stuff. I’m unsure, if this feature (mask movement) is restricted to the licensed version? For a trial there is to much stuff belonging to license server and registration instead of short and impressive tutorials.
Maybe later on I will give it a try again.
Is there no solution for doing it with build in features of FCP X and/or Motion? I’m no professional and will need this feature for one family video of our last vacations.
