imovie '11 keeps crashing

Same here.

Same here....I found another page with many suggestions to fix it, including a person who spent the day with applecare. He thought he had fixed it but then he said he updated again and it crashed. Hopefully will see a new update tomorrow!!!

We just updated to Lion in order to download iMovie 9.0.6, and must have done this the day Apple released it or just a few days later. iMovie would crash whenever importing video or photos, from the desktop or iPhoto. After reading a number of crash reports in the help forums and reading our own crash report, I deleted 2 files from Mac HD>Library>Application Support>3ivx and restarted. iMovie worked fine. I hope this helps--I spent the last few hours investigating this, trying to find and delete various preference lists, etc. We're running an older (2007) aluminum iMac with 2 gig of RAM.

you deleted 2 files... which ones?

They were the only 2 files in that folder, and of course they're now deleted so I can't remember exact names. One of them was a plist file, the other I think said "dylib" and both had 3 ivx in the file name. I tried to recover the crash report on the other computer, but I couldn't match it to the exact files I deleted. I restarted with the 2 files in the trash, and then deleted them permanently when iMovie worked properly after restart.

3ivx.plist

lib3ivxEnc.dylib

I simply moved these two files out of the app support folder and iMovie has opened fine (before it was crashing immediately after looking for all my movie files.)

Just spent an hour on the phone with tech support on this issue. This thread gave me everything I needed (and had not gotten!)

I spoke with support and went to the Genius bar at my Apple store. The Genius bar technician uninstalled and reinstalled iMovie. It worked for a day and is now back to crashing. I'll try finding and removing the files mentioned by StackTrack.

There is obviously something wrong with the iMovie update.

Thank you guys from middleburycommunity television and StackTrack, it worked ok for me , up and running. appreciate the help.

Just passing along info from another thread.

Anyone know what 3ivx is? I actually see an "Uninstall 3ivx" app in my launchpad screen.

Does anyone have any other ideas...we just upgraded out operating system and installed imovie 9.0.6 and it opened the friday night but now it just spinslike its trying to create thumbnails. I unistalled and reinstalled with no success and I do not have either of the files mentioned above.

i just went from a 2006 macbook to a macbook pro i bought on july 3. i transferred everything using time machine and imovie would not work at all. crashed all the time. i tried everything, erasing imovie preference file to repairing iphoto database, etc since the 3rd. finally, thanks to this thread, i uninstalled 3ivx or whatever it is, and flip video software. now it works great. i cant believe it was so simple and still took three days. thank u guys so much!!!

That worked for me. Thank you.

Having the same problem here. Saw the above thread. I just clicked on "uninstall 3ivx" and now iMovie works. Not sure what 3ivx was and hope I don't need it for something else.
