Insta360 One X Videos for YouTube 360

Hi Guys

Apologies for the newbie questions... I want to use my Insta360 One X to make videos for YouTube 360.

I've figured out how to use Insta360Studio FreeCapture and keyframes to make "flat" MP4s where the camera is pointing in the direction I want while the video runs.

This isn't what I want, though. What I want to do is to use a tool like the Pivot Point or Smart Track function on the iOS app to move the focus on video clips around, then merge a series of clips into a project, and then export the project as a 360 degree video for YouTube 360.

I've downloaded Final Cut Pro as well as Insta360 Studio.

How do I do this, please? What tools do I use, and are there any videos/tutorials?

Thanks!
