When using a computer in an academic lab, you must be aware of specific things when saving your project. The file will be too large to save on your home directory, but you will be able to save it to the local machine's hard drive. This way, if you work on the same machine later, the file will still be there. If you move to a different machine, you will be unable to access the file.
When a project is created in iMovie, it is automatically saved in a folder on the local hard drive.
