Hi there IGrock,
Being able to sync all of your files across your devices using iCloud is amazing, and we certainly want to help however we can for you to enjoy it as well.
You mentioned wanting to sync iMovie with iCloud, but do you currently see that option in your iCloud preferences within your Mac? Just in case, this link has more details about setting up iCloud along with customizing it: Set up iCloud on your Mac
If you already have iCloud set up in your Mac, is other content syncing without any issues?
Cheers!
