Share your movies
When you share your movie, QuickTime Player creates a version of the movie that’s optimized for how you choose to share.
Open the movie in QuickTime Player, choose File > Share (or click the Share button
in the playback controls), then choose how you want to share your movie:Mail: The movie is added to a new email message in the Mail app.
Messages: The movie is added to a new message in the Messages app.
AirDrop: When you choose AirDrop, QuickTime Player lists other people who are using AirDrop. If AirDrop isn’t listed, your computer doesn’t support it. If you can use AirDrop, click the users you want to share with.
Add to Photos: The movie is added to your Photos library.
Notes: Enter text to create a new note with the movie, or select an existing note to add the movie to.
YouTube: If you have a YouTube account, you can upload a movie to YouTube.
To set up additional sharing options (such as Facebook, Flickr, and Vimeo), click the Share button in the playback controls, then click More.
