iMovie 5 and earlier: Importing Files Larger Than 2 GB
Products Affected
iMovie
iMovie (versions 1-5) can import files up to 2 GB in size.
Using the Import command in iMovie's File menu, you can import QuickTime or DV files that are up to 2 gigabytes (GB) in size. If you try to import larger files, iMovie may unexpectedly quit, or you may see a message that says the file is too big or an alert stating the "file could not be imported: (-40)".
With QuickTime Player Pro, you can split a large file into two or more smaller ones that iMovie can import. QuickTime Pro is available from the Apple Store.
See "QuickTime Pro: How to Edit Portions of a Movie" for steps on how to split a large file using QuickTime Pro.
