Cannot import iMovie 9 files into iMovie 10

I have this exact problem. Have you tried in addition to the above deleting the iMovie 10 download and downloading again?

Pascal, I see you do not have this question anymore. Please let me know what you did to solve this issue.

I am having this same issue and I have projects to complete with a deadline of this Friday. Any help or solution to this issue is much appreciated. I had all my events and projects on a server, which in iMovie 9 it allowed access to the server of your choice to work from, freeing up your hard drive space. iMovie 10 does not seem to allow that functionality.. which is really not something I am very pleased with. I tried copying the files from the server into the movies/ directory and the folders still say "imovie events" and "imovie projects". Yet when trying to import into imovie by clicking the import button at the top, they are greyed out, just as Pascal described, and cannot be selected. Please, someone tell me there is a way to convert the project files or some special button to click to allow additional functionality that will allow the import of these "archive" type files!

I have the same problem too. I'm wondering how could this possibly happen with this new version.

I have possibly found a solution. Go to your Movies folder and delete the update to iMovie 10 files in the event folder and project folder (if there is one there). Then delete the newly created Library1 file and the Theatre file. Trash them. Then re-start iMovie. If like mine it opened with no events or projects. Under file there is a drop down menu toat says something like update projects and events. I am in the middle of doing that and so far so good. This allows the iMovie manager to locate the previous iMovie 9 database and upgrade. Just importing to iMovie 10 will not do the same I do not believe. Also, it stated that it will leave the iMovie Events and Project Database intact and allow you to run both. Great for backup but bad for HD space.

Your solution works for me! Thanx

Great news. Mine still has issues but I have traced it to a corrupted project file. I watched to see when iMovie quit and then moved that project to another location it it seems to be working.

I tried this and nothing works. Everyfile i have wether its a project or a event will not load. it keeps saying all my files are not supported. Which doesnt make sense since they were all made by previous imovie.,

i follow your advices e now imovie works perfectly!!! And no much more hd space take over: i've the same gb than before updating my library! THANKS

Tried this solution to no avail. Like *jvjogler1 I have my Projects and Events on an external HD; the new iMovie doesn't seem to have this option. This is very frustrating.

By following your recommendation, I succeeded to import all my events; but beforehand I had to repatriate these to my internal HD (iMOvie 10 is unable to find something on th external HD).

Remaining question: how do I repatriate my Projects?

you have to move "iMovie Events" and "iMovie Projects" folder to the root (top level) of the hd to make it work. It's described in a kb article (http://support.apple.com/kb/HT6012)…

Mike\'77,

Thank you for helping provide a solution! I am going through the update right now and I think it is working!!!

Yay! 🙂

Still wish there was the ability to have these projects stored on a server like before or a back up drive. Apple, if you are watching.. please, please consider this in the next update or future update! These files (as I am sure you have to be able to comprehend) are huge and slow down computer processing. With so much memory consumed by event footage and final video clips, I want to keep my MacPro hard drive as free as possible so it runs with max efficiency and speed.

Mike \ '77 work around worked for me. Message came up that some files could not be updated, which I said OK. All remaining projects and events came across and now appear in iMovie 10

same problem here.

to resolve go to

in the folders of imovie 9 (eventes of imovie, imovie projects, etc)

there is a file with the name "UpdatedToiMovie10", delete that file and go to

Imovie -> file-> upadte projets and events.

P.S- It take some time you have to wait, DON´T STOP THE IMOVIE.
