14 (iMovie for iPad) - Sharing and Publishing Options
When you are finished editing and ready to publish your project, click the MY PROJECTS tab at the top to return to the home screen. Then click the publish icon at the bottom of the screen, which looks like a box with an arrow on it. Select the desired location for sharing. In this example, I selected YouTube.
This step is included in the "Video" chapter of the forthcoming EPUB eBook, "Playing with Media: simple ideas for powerful sharing."
