No matter what I do I cannot get iMovie to open an import window when I connect my Sony NEX-VG30.

It used to without problem but now it won't.

Anyone have any suggestions?

It's really frustrating having to load all my footage onto one of our other computers & then transfer it to my main machine...

iMac, OS X Mountain Lion, Late 2009 27inch 2.8GHz i7

    When iMovie doesn't work as intended this can be due to a lot of reasons


    • iMovie Pref files got corrupted - trash it/they and iMovie makes new and error free one's

    • problem in iMovie Cache folder - trash Cache.mov and Cache.plist

    • Creating a new User-Account and log into this
    - forces iMovie to create all pref. and cache files new and error free

    • Event or Project got corrupted - try to make a copy and repair

    • a Codec is used that doesn't work

    • version miss match of QuickTime Player / iMovie / iDVD

    • preferences are wrong - Repair Preferences

    • other hard disk problem - Repair Hard Disk (Disk Util tool - but start Mac from ext HD or DVD)

    • External hard disks - MUST BE - Mac OS Extended (hfs) formatted to work with Video

    ( UNIX/DOS/FAT32/Mac OS Exchange - works for most other things - but not for Video )

    • USB-flash-memories - usually do not work


    • Net-work connected hard disks - usually do not work (most often not fast enough and WRONGLY FORMATTES as DOS etc


    •  iPhoto Library got problems - let iPhoto select another one or repair it. Re-build this first then try to re-start iMovie.

    This You do by

    - close iPhoto

    - on start up of iPhoto - Keep {cmd and alt-keys down}

    - now select all five options presented

    - WAIT a long long time (>20 hours are not strange)

    • free space on Start-Up (Mac OS) hard disk to low (<1Gb) - I never go under 25Gb free space for SD-Video (4-5 times more for HD)

    • external devices interferes - turn off Mac - disconnect all of them and - Start up again and re-try

    • GarageBand fix - start GB - play a few notes - Close it again and now try iMovie

    • Screen must be set to million-colors

    • Third-party plug-ins doesn't work OK

    • Run "Cache Out X", clear out all caches and restarts the Mac

    • Let Your Mac be turned on during one night. At about midnight there is a set of maintenance programs that runs and tidying up. This might help

    • Turn off Your Mac - and disconnect Mains - for about 20-30 minutes - at least this resets the FireWire port.

    • In QuickTime - DivX, 3ivx codec, Flip4Mac, Perian etc - might be problematic - temporarily move them out and re-try

    (I deleted the file "3ivxVideoCodec.component" located in Mac HD/Library/Quicktime and this resolved my issue.)

    I solved the problem by removing the file: 3ivxVideoCodec.component. after that, up-dated iMovie runs ok.


    Last resort: Trash all of iMovie and re-install it

    Thanks Bengt. All great tips. I didn't feel like messing around so did a complete delete (using Clean My Mac) & reinstall & all is good now.
