    Folks as one of the first to discover and report this bug ... i'm telling you straight up ... complete your projects in 9.0.5 for many reasons ... then quit ... open iMovie 9.0.2 (after restoring using Time Machine) and render your product.  That's the BEST easiest solution.  Then alternative, which i can personally confirm works ... is to duplicate your project (mine was 20min) into pieces that iMovie 9.05 will render and then use QuickTime 7 (not QuickTime X) to reassemble. 


    Yes, frames might get hosed and syncing audio will suck too.  Like i said, do your job in 9.05 and render in 9.02.  unfortunately ... 9.0.5 may not record the rendering ... ok, it won't! ... and the project will not be "frozen" and collected.  Sorry.  All i can say is ... been there, done that ... > Track 2011 > State Championships =D

    I've solved a work around.


    It will require that you move some of your imovie projects from your iMovie Projects folder located in your users library files.  


    First Quit iMovie.  Go to your users folder, then open movies, then open iMovie Projects.  You will have to move the contents of your iMovie Projects folder to a desktop folder or Some other folder in your system. In my case I created a new folder on my desktop and called it imovie projects2.  Be sure to leave only the file you want exported in your original iMovie Project folder.    Re-launch iMovie and your problem is solved.   I've ran several tests and it seems that you can only have a max of 4 projects in your iMovie project folder at one time.  If you have 5 projects in that folder and you try to export it will not work.   It's rather annoying that you can only have 4 projects at a time, but that solves the problem.    Good luck.

    same problem ,I got my Macbook Pro yesterday from Apple store.

  • Raymond Kam Level 1 Level 1

    For me, I needed to unmounted the drives storing the imovie events as well.That finally solved the problem.

  • acssns Level 1 Level 1

    I've been dealing with this, like the rest of you, for too long.  However, I simply quit iMovie and restart it.  This works every time.  Does this not work when a movie gets longer than 5 mins? 

  • OutdoorGearLab Level 1 Level 1

    Thank you gonzalofrom562  Your solution worked! I had 300+ projects and every time I created a new project the error message came up more and more frequently. (Oh the hours I wasted restarting iMovie...) Then I moved 110 of those projects to a new folder on my external hard drive and problem solved. I am using MacBook Pro 2.3 GHz i7, 8 GB Ram with iMovie 9.0.4   

  • digimurr Level 1 Level 1

    I have had this issue since going to Lion, even bought a 27" Imac powerhouse and same issues.  It's EXTREMELY ANNOYING!  WHY DOESN'T APPLE SEE THESE POSTS?  WHY DOESN'T SOMEONE FROM APPLE RESPOND TO THIS GROUP!  RESART IMOVIE... WHAT GARBAGE!!!

  • Apple Geek 0819 Level 1 Level 1

    First, you do need to relaunch iMovie. Second, rather than opening the movie you want to export, you right-click on it and select export in the Project Gallery. This obviates the need for iMovie to load your project into memory, and allows it to commit all of the computer’s memory to the rendering task.

  • Chief_Fish Level 1 Level 1

    Gonzalo's solution works.


    I tried moving the projects (~10) to external device, but iMovie was still loading those and was taking 10 mins to load only to find out I still didn't have enough memory (insert explitive). Moved the project I wanted to the primary internal drive, unmounted external device, iMovie loaded much faster and only found the project I wanted to share. Was able to share without the memory problem.


    I'm not a poweruser by any means and I understand that iMovie isn't supposed to be a pro-level program, but I'm really surprised that Apple has allowed this very frustrating issue to continue without any apparent solution. Sometimes I really love my MAC and other times it drives me crazy!!!

    To all with this issue:


    Just finished an extensive APPLE SUPPORT session on this issue and here's the deal:


    If you have tons of PROJECTS in your iMovie Projects folder, you are running into the Memory Error message because iMovie is struggling to mange your current project AND the other projects in your folder.


    You can:


    1.) delete old projects

    2.) create a folder called iMovie_old_Projects to store your nonessential projects in


    This reduction in the number of projects will alow you to export or share your current project out, no problem.

  • chaamp1 Level 1 Level 1

    try to seperate iMovie9 files with iMovie11 by renaming the iMovie Projects folder with another name like "iMovie Projects OLD", you will be able to launch only movies created with iMovie11. this should work fine.
