trouble outputting project

Attempting to share iMovie project to Vimeo yet it keeps crashing. Had worked on a previous attempt to upload, but made edit changes since and wondering if data is corrupt somewhere in the timeline. Same issue when opting to Save File (it’s a 45 minute long video). Any feedback would be great.

Mac mini, OS X 10.11

Hi, McCready2112,


If you have not done so already, update your iMovie version and operating system to current versions.


Sometimes deleting preferences cures export problems. Since it is so easy to do, try deleting preferences. Open iMovie while holding down theOption and Command keys and select to delete preferences in the box that appears. iMovie will open in a new library. Reopen your old library to get back to your projects. Now see if you can share out.


Another thing you can try is to copy your media into a newly created project and see if that cures the problem. To do

that, do an Edit/Select All, Edit/Copy, of the media in your project and then Edit/Paste it into the newly created project. See if you can share out from there.


It is possible, as you mentioned, that there is a corrupt frame or clip in the project that is causing the crashing. Expand the timeline with the slider located above and to the right of the timeline. Then scroll slowly through the project, looking for black frames, white flashes, and any other signs of corruption. Cut out any that you find and then try to share. Good to work with a duplicate of your project so that you can preserve your original.


All else failing, try redownloading iMovie. To update/redownload iMovie 10, drag your iMovie 10 app from the Applications folder into the trash, but do not empty the trash. Sign in to the app store and open your purchases folder by clicking on your name at the bottom of the app store side bar. (NOTE: For El Capitan and older, click on the Purchases tab at the top of the app store screen and then sign in. Click on Purchases again to reveal your purchases.)  You will see your purchases

displayed, including iMovie 10. Redownload/update iMovie from there. If not successful, drag your present iMovie app out of the trash and return it to the Applications folder.


There are other things that can cause crashing, such as low free space. So check that you have enough space for iMovie to function efficiently.
