iMovie11 HD 1080p Export Error 108

May I ask you to resolve the error I get in the attachment when I try to export a project in iMovie11 to a HD 1080p MOV file.

The error reads: “Unable to prepare project for publishing. The project could not be prepared for publishing because an error occurred. (-108)”

I did not “finalise” my project. I initiated the export using the following menu options: “Share” then “Export Movie” then click the radio button for “HD 1080p”. The export starts and runs for approx 15min then gives the error in the attachment.

I am running the latest version of iMovie11: 9.0.4 (1634). My raw project is 116 MB and 66min in size. I am working on a 15.4inch MacBook Pro I bought in Jan 2009 with the following spec: Mac OS X version 10.6.8, Processor is 3.06 GHz Intel Core2 Duo, Memory is 8 GB 1067 MHz DDR3 with 250GB solid state drive and 120GB free.

I am able to export using “HD 720p” and I have exported another smaller project (6min) using “HD 1080p”.

I don't know the exact error, but if it STARTS the process but can't FINISH it this is usually indicative of you not having enough temp free space on your HD. The finished product won't need that much space, but while it's working the program will need a HUGE amount of free space.

The fact that you could accomplish short projects without incident tells me that 120GB free space is simply NOT ENOUGH to render a 66min 1080p project. I'd suggest connecting to an external drive and moving the project there. I can't guarantee that will fix the problem but I think that automatically moves the "rendering" process to the drive where the project is located.
