iMovie and iMovie HD Troubleshooting

1. Disk Partition Format:
   iMovie project must be created/opened/modified on a Mac OS Extended or Mac OS Extended(Journaled ) partition. If not, please move the project to a right partition .
   
2. QuickTime add-ons:
   Incompatible QuickTime add-ons may cause iMovie crash, for example Divx, Flip4Mac, or 3ivx, either update them or delete / move these add-ons to other folder.
   These add-ons may reside on /Library/QuickTime folder which will affect all users, or on users' ~/Library/QuickTime folder which will affect this user only.
   
3. Third-party iMovie plug-ins:
   Please update them or delete/move them to other folder.
   They may reside on /Library/iMovie or users' ~/Library/iMovie folder.
   
4. Disk Space:
   It may ask for at least 2GB or more free spaces to edit a iMovie project. Depends on your project size, it may ask for more.
   
5. In-compitable software issues:
   The most easy way is create a new user, but it may not a option in some scenario.
   
6. Permission:
   This may be the issue. Don't know how to fix permission? Ask administrator.
   
7. Conflict Version:
   If you updated it to a newer version before but downgraded back, this might be the issue. The old version will not read the new version plist file correctly. So delete the plist file may be the choise.
   All related plist files:
   ~/Library/Preferences/com.apple.iMovie*.plist
   ~/Library/Preferences/com.apple.quicktime*.*.plist
   
8. Font Related:
   If you migrated your user profile from a old system, this might be the issue:
   Delete/move ~/Library/FontCollections folder.

iMovie和iMovie HD的問題解決

1. 磁盤分區格式:
   這個軟件要求它的文件應該保存在Mac OS Extended格式的分區中，如果不是，或者移動到一個符合要求的分區，或者找到一個無用分區格式化成該格式。注意，Mac OS Extended (Journaled)分區格式也是支持的。
   
2. QuickTime的附加軟件:
   QuickTime的附件附加軟件很有可能造成iMovie的運行問題，比如Divx, Flip4Mac, or 3ivx等。解決辦法，升級這些附加軟件，如果找不到／無法升級，可是移動或刪除他們, 一般來說，它們儲存在下面的目錄里面： /Library/QuickTime 或者是用戶的 ～/Library/QuickTime
   
   
3. 第三方的iMovie插件:
   或者升級或者刪除／移動這些插件，它們可以在 /Library/iMovie 或者是用戶的 ~/Library/iMovie 目錄里。
   
4. 磁盤空間:
   iMovie可能根據你所編輯的文件的大小，需要至少2GB的空余磁盤空間，如果空間不足很有可能造成渲染等操作失效。
   
5. 其它的用戶兼容問題:
   最簡單的方法就是新建一個用戶，但是有的時候這種方法并不實用，比如在多用戶的網絡環境中.
   
6. 權限問題:
   這個問題最簡單但是有的時候可能被忽略的。你不知道如何應付這種情況，找系統管理員或者有經驗的用戶。
   
7. 版本之間的沖突:
   這種情況發生在，你可能運行了一個較新的iMovie版本后，再運行一個舊版本的時候，由于舊版本不識別新版本的plist文件的設置或者某些設置失效，而導致各種運行情況發生，所以需要刪除響應的plist文件，最常見的有:
   ~/Library/Preferences/com.apple.iMovie*.plist
   ~/Library/Preferences/com.apple.quicktime*.*.plist
   
   
8. 字體相關的:
   當用戶使用用戶遷移工具遷移升級系統的時候，有可能造成這樣的問題. 刪除下面的文件夾:
   ~/Library/FontCollections
