IMovie, the video editing and management software developed by Apple, allows you to share your favorite movies on such sites as Facebook, YouTube, Vimeo and CNN iReport, directly from iMovie's interface. When you share a movie from iMovie, you can enter a title and description for it, as well as change its size and privacy settings. IMovie uploads the video directly to your Facebook account, where it appears on your Timeline.
Click the "Project Library" button in iMovie, and then choose the video you want to share on Facebook.
Click "Share," and then choose "Facebook" from the drop-down menu.
Choose your Facebook account from the Account pop-up menu, and then type your Facebook password into the Password field. To add a new Facebook account, tap "Add," and then follow the instructions.
Select who can view your video from the "Viewable by" drop-down box, and then type a title and a description for your video into the corresponding boxes.
Choose the size of the video -- either "Mobile," "Medium," "Large" or "HD" -- and then click "Next."
Click "Publish" to start uploading the video to your Facebook profile.
Information in this article applies to iMovie '11. Procedures may vary slightly or significantly with other versions or products.
The default video size is "Medium," the equivalent of 480p. The "Large" and "HD" options produce higher quality videos, so it takes longer to upload them to Facebook.
By default, videos posted by iMovie are private, meaning only you can view them. To share them with your friends, choose "Only Friends" from the "Viewable by" box.
