Did You Know?—Saving While Building Your Movie
It’s a good idea to save your work periodically as you make changes. Because
iMovie HD saves your original footage even after cropping, you can still retrieve
cropped footage after you save.
To save your project:
m Choose File > Save Project.
At times you may want to go back to the last saved version of your project, canceling
any unsaved changes.
To revert to the last saved version of your project:
m Choose File > “Revert to Saved.”
You can also save a copy of your project and give it a different name. You can then
create a different version of the movie or use parts of the movie in a new project.
Saving multiple copies of a project can be extremely useful, but can also use large
amounts of disk space.
To save a copy of your project with a different name:
m Choose File > Save Project As.
Then enter a name, choose a location for the copy of the project, and then click Save.
