Feathering into black
Hello folks, I am trying to accomplish what I have done in the first picture in FCP but cannot seem to figure it out,, I now understand I need to use a mask like I have done below but cannot figure out how to feather it into black, in the timeline I have black as the other video source but still no luck in having it blend. Can anyone explain how I can get the video feathered like the image above?
Thanks
