Hi
Do I know - NO - BUT I've a general approache
If iMovie used to behave in one way - then suddenly stops doing so e.g. after a Panic/Forced Halt (very common origin)
then most probably the iMovie pref. file got corrupted
this file contains settings as PAL or NTSC and other things that one want iMovie to keep till started next time. May be choice of font and size too.
Trach this iMovie pref file - and it will revert to factory settings - then set it at Your liking and it most probably will remain.
• Delete iMovie pref. file
iMovie pref. file resides.
Mac Hard Disk (start-up HD)/Users/"Your account"/Library/Preferences
and is named. (one or more of these)
com.apple.iMovie.plist
com.apple.iMovie3.plist
com.apple.iMovie7.plist
com.apple.iMovie8.plist
com.apple.iMovie9.plist
com.apple.iMovieApp.plist
and find
com.apple.iApps.plist
While iMovie is NOT RUNNING - move this/these file/s out on to desk-top.
Now restart iMovie.
If You run Mac OS X.7 or more - then the Library in the User-account folder is invisibly and need to be set to be viewable. IT IS NOT in the Library on Root level (when opening MacintoshHD - first window = root level)
( It can be done like this: Open Terminal, then enter: chflags nohidden ~/Library
Press return, then restart, and it will always be visible until the next major update, when you do the same thing again. )
or - do like this.
On the Finder window at the top left of the screen,
Hold down the Option key and clicked on Go.
This allowed You to see the Library folder and select it.
Then keep the Option button pressed down in order to see and select the Library folder.
Once found it, You are able to navigate to the iMovie preferences file and move it to the trash. iMovie then start’s up fine!
Yours Bengt W
