    You may not have sufficient free space on your hard drive.

    I have 343gb free of 499gb?

    Ok, that eliminates that potential error!


    It can also mean corrupted/invalid data. Are you importing or exporting?

    Can there be any external hard disks - if so How is/are it/they formatted ? Must be Mac OS Extended (hfs) if used for Video.


    UNIX/DOS/FAT32/Mac OS Exchange - works for most but not for VIDEO.


    What this means in Your situation is above me.

    • free space on internal boot hard disk? How much ?


    Video codec

    • streamingDV, AIC etc. (not .avi, .mp4, .m4v, .wmv etc as they are containers not codecs)



    • in what format ? .jpg, .bmp, .tif, else ?



    • from where/what format ? iTunes, .avi, .mp3, .aiff, else ?


    The "com.apple.iMovie.plist" file


    Many users has not observed that there are TWO libraries.

    • Library - at root level

    • Library - in user/account folder - THIS IS THE ONE to look into


    from Luke Burns

    I fixed the problem.. but it was very, very strange. I had a very long section for credits and set the line spacing to 1.0.. for some reason this caused it. I removed it, and it worked fine. I put it back, and I couldn't preview or play the video.


    I don't know why that could cause that big of a problem, but it did..



    You need more free space on your hard drive.



    After phone support from apple I ended up creating a new project and adding all 117 clips back in individually till I found out what clips flagged and would not allow me to export. I had 3 I deleted and replaced and everything works now 1hr after tedious work....


    Where do Your material come from

    • Camera

    • External hard disk

    • USB-memory


    And all are connected so that iMovie can find it ?

    Thanks for all your replies guys.


    I read all of the different stuff that had been posted and what was online already and decided to start the project again. I was more carfeul about the content and where it was and also checked as I went that it wanted to render still, which it did and is now complete!

    How can you check which clips flag when restarting the project?
