I have a video clip in Final Cut Pro, and what I want to do is this: start out with the frame zoomed in on the guy’s face, and as the clip plays, have it pull back out to show the full frame. How I do dat? My HelpFu skills are sucking today. 
All I can figure out is how to play the whole clip zoomed in or the whole clip zoomed out.
Ooooh I think I found the right place. It’s in the “motion” tab, right? I have to use the pen tool to put dots on the timeline, then mess with the scale and center point? (I know where this stuff is in Premiere, it’s just a matter of finding the equivalent tools in Final Cut!)
Yup, that’s it exactly… keyframes are what you need here.
