How do I access the "advanced settings" option in iMovie 10.0.9?
I want to be able to merge two videos in one, such as having on clip playing in the corner while the other continues. I know on older versions of iMovie you were able to go to iMovie > Preferences > check, "show advanced settings". On this new version you are not shown the same options as before & I really want to figure out how to do so.
iMovie 10, OS X Yosemite (10.10.4)
