Saving unfinished iMovie projects

Sharing out a project creates a standalone movie. You could drag the moviet into a new iMovie project as one large clip and do some limited editing, like adding titles, doing overlays, adding some effects, splitting and deleting segments. Any edits that were embedded into the movie itself could not be changed.

However, you do not need to edit the shared out movie. After sharing out, the original project still remains and is not "finalized", so you can go back to it, make changes, and share it out again if you want. Also, you can keep any number of unfinished projects going at once and you can return to them later and continue to edit them. The unfinished projects are automatically saved in the Projects browser, that is like a library where your finished and unfinished projects are displayed as icons and are stored for future editing or sharing out.

iMovie 10 automatically saves your project as you are working. You can close a project and return to it later to do more editing. No need to save it as a file, but you can share out a file as many times as you want and always you are able to return to the original project to do further editing.

Great. Glad I could help.

When you want to go back to a project to make changes, maybe several revisits, you make a duplicate of the project and work with the duplicate. That way you always preserve your original project. To make a duplicate, open the Projects Browser screen (the one where your projects are displayed as icons) and move your cursor over the project's title. A little circle with dots in it will appear to the right of the title. Click on that to get a drop down menu that will give you a "Duplicate Project" option. You can make as many duplicates as you want. They take up insignificant space.
