Hi, I downloaded ‘Elegant Opener’ for Final Cut Pro but don’t know how to install it.
There are no instructions.
I only have Final Cut, not Apple Motion, but I think it works just with Final Cut.
How do I install?
Best, Michael.

Is the file definitely a FCP file and not a Motion, Premiere ot AE format?

What’s the item link?
