Did You Know?—Saving Your Finished Project
If you can’t burn a disc right away, or if you want to move or back up your finished
project to another computer, you can archive it or save it as a disc image.
Archiving your project creates a copy of your project, keeping all of its elements
together and linked within the project file. It can take a while to archive a large
project, but you can move the file to another computer or hard disk, and then open it
at any time for further editing or burning onto a DVD.
Saving a disc image of your project means creating a file that is formatted just like a
finished DVD, except it’s not actually burned onto a disc. All the media has been
encoded into the format used on a DVD, and you can play it on your computer by
double-clicking the disc image icon. The disc image can be moved to another
computer or hard disk, but cannot be edited further. You can use Disk Utility in Mac
OS X to burn the disc image to a DVD when you are ready.
