    A. Don't know - I don't do (ever)


    B. I use an external hard disk - to off load Event's and Project's from Start-Up Hard Disk

    • MUST be - Mac OS Extended formatted (mine are journaled) - UNIX/DOS/FAT32/Mac OS Exchange = will NOT work with VIDEO


    • Should be a FireWire or Thunderbolt one - as USB/USB2 performs badly to me and especially when filling up or if HD-material is used


    • ALL MOVE OF Event's AND Project's - MUST BE DONE inside the iMovie Application - DO NOT MOVE or Alter any folder named

    - iMovie Event's - or -

    - iMovie Project's

    ON DESKTOP/FINDER - as this will break connection to iMovie and can be anything from Hard to impossibly to mend.


    Yours Bengt W

    The Event files contain your physical video clips.


    The Project files contain a text file in hexadecimal that provides the recipe for creating your movie. For example, it will provide a path to an event clip, as will is which frames to use as in and out points. It will contain instructions in which titles and transitions to apply. It iwll provide the filename and path to any music clips you have used from iTunes and the path to any photos you use from iPhoto.  So if you delete your Events or your iPhoto or iTunes libraries, you will no longer be able to edit the project.


    The Project file also contains copies of any movies you have shared to Media Browser or Finalized. These are deleted if you start editing the project some more, because it assumes you will be replacing them with a changed file.

    Yes, if you never, ever want to have access to those event clips again, you can delete.


    I am not sure why Apple gives you two copies. It may have something to do with whether you have your iTunes Library set up to automatically import and manage file or not. In any event, you can delete one of them.

    I have moved project files around without problem. It's far easier than doing it within iMovie. You will have to restart iMovie for the new arrangement to take effect. I wouldn't move the event files around, though.  --AEF

    Be sure to keep them in the "iMovie Projects" folder tree!  --AEF

    Your project file is actually a package which contains several files and folders. IT contains the hexadecimal text file as I mentioned above.

    If also contains a Movies folder which includes your finalized movies. If you did not finalize, it contains any movies that you have SHARED to media browser or to iTunes, YouTube, etc.


    These movies will still be there if you delete your events. However, I prefer to keep a good copy outside the project package, because if I edit the project at all, these copies in the Project package are deleted. So it is best to have a copy stored in your own folder somewhere, or in iTunes, where it cannot be accidentally erased.


    So trashing your Events will not damage these movies in the Project Package, but it is easy to delete them, so I wouldn't rely on them as my only copy. But you can still use the finalized project to Share to iTunes, Share to YouTube, etc. You just can't edit it anymore. If you Share to YouTube from a finalized project, it does not re-render the project (would need the event clips for a render). It just makes a copy of the completed h.264 movie in the project package and puts it in iTunes.
