Thanks, that worked. Though you are right, not very user friendly, but maybe I am missing something. To get rid of the leftover black space, I had to drag my source window to fit my scene (not sure if I am using these terms right...), but then the aspect ratio was off, so I had to adjust my crop so that its aspect ratio was the same as my screen. Maybe there is a better way to do this?
Also, I'm wondering if there is a tool to make my mouse clicks obvious, perhaps a growing ring like other software do.
I am very impressed by this software, not user friendly, but very functional.
Thanks,
Sam
