Share your movies from QuickTime Player on Mac
When you share your movie, QuickTime Player creates a version of the movie that’s optimized for how you choose to share.
In the QuickTime Player app on your Mac, open the movie.
Choose File > Share (or click the Share button in the toolbar), then choose how you want to share your movie.
If AirDrop isn’t listed, your computer doesn’t support it.
Note: If you opened an movie stored on iCloud Drive, choose Share File from the pop-up menu to share the item with other iCloud users. See Use iCloud File Sharing to share folders and documents with other iCloud users.
