I have a screen-cast clip. On a white background, I have an icon which I'd like to cover with a shape or something. In fact, I've tried using a vector shape and it partially does its job. The problem I'm having is that the clip starts with a fade in/out transition and I'd like to "hide" the icon also during those frames. Adding the same transition to the vector shape didn't help, so maybe I'm just using the wrong approach.
How could I hide that icon so that it looks natural also during the transition frames?
