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的问题解决

1. 磁盘分区格式:
   这个软件要求它的文件应该保存在Mac OS Extended格式的分区中，如果不是，或者移动到一个符合要求的分区，或者找到一个无用分区格式化成该格式。注意，Mac OS Extended (Journaled)分区格式也是支持的。
   
2. QuickTime的附加软件:
   QuickTime的附件附加软件很有可能造成iMovie的运行问题，比如Divx, Flip4Mac, or 3ivx等。解决办法，升级这些附加软件，如果找不到／无法升级，可是移动或删除他们, 一般来说，它们储存在下面的目录里面： /Library/QuickTime 或者是用户的 ～/Library/QuickTime
   
   
3. 第三方的iMovie插件:
   或者升级或者删除／移动这些插件，它们可以在 /Library/iMovie 或者是用户的 ~/Library/iMovie 目录里。
   
4. 磁盘空间:
   iMovie可能根据你所编辑的文件的大小，需要至少2GB的空余磁盘空间，如果空间不足很有可能造成渲染等操作失效。
   
5. 其它的用户兼容问题:
   最简单的方法就是新建一个用户，但是有的时候这种方法并不实用，比如在多用户的网络环境中.
   
6. 权限问题:
   这个问题最简单但是有的时候可能被忽略的。你不知道如何应付这种情况，找系统管理员或者有经验的用户。
   
7. 版本之间的冲突:
   这种情况发生在，你可能运行了一个较新的iMovie版本后，再运行一个旧版本的时候，由于旧版本不识别新版本的plist文件的设置或者某些设置失效，而导致各种运行情况发生，所以需要删除响应的plist文件，最常见的有:
   ~/Library/Preferences/com.apple.iMovie*.plist
   ~/Library/Preferences/com.apple.quicktime*.*.plist
   
   
8. 字体相关的:
   当用户使用用户迁移工具迁移升级系统的时候，有可能造成这样的问题. 删除下面的文件夹:
   ~/Library/FontCollections
