    Can I ask what the specs of your media are?

    have the same problem, and when i upload videos to facebook or youtube, they are all out of sync. if i un-install imovie 11, and re-install the older version, although it will fix this problem, does it mean i will loose all my projects?

    May I ask if you are talking about live audio or not? I have a project to which I added music (no live sound) and it still works fine in 9.0.1. So I suspect this problem is only for live audio.

    Same here! I had a LONG project of nearly two hours! It also went out of synch! I ended up going back to Time Machine, reinstalled from last Oct 1, iMovie9. That made iMovie11 , the 'original' iMovie! So using iMovie 9 I could fix problem. Exported to Apple TV.... flawless on Samsung 50" plasma.
    Then used Toast 10 to burn both NTSC and Pal D Disks!
    Funny ..exported my movie from iMovie 11 ...moved there over night (?) to 11 ..then exported to desktop as DV file...some 22.4 GB ...dropped file on Toast as DVD Rom UDF ..made two copies, one NTSC ( played perfectly on iMac/MBP and Samsung via old ( 2004?) Toshiba DVD player. The Pal D, plays on computers in iDvd, but not on our TV for obvious reasons!

    So yes...long story, but iMovie11 does have glitch/bug!
    Had fix it in iMovie 9!

    NOW.... going back to iMovie 11, and earlier movie, I cannot in Project Library alter the music of an earlier Project. ...it opens up, plays, when one drags music as per instruction it goes green, gives a PLUS, even puts the 'green line out.... but will not PLAY!!! !

    Tried aIl the triicks....restarted.... etc etc...to no avail! Is most frustrating ...and there seems to be ino way around the problem! Annoying as I want to burn both NTSC and Pal D copies!

    Another victim of the sync problem but I believe the problem is not limited to the version 9.0.1 update. I have checked the version of Imovie installed on my Mac pro and it shows version 9.0. I intentionally avoided the upgrade due to the comments I've been reading.

    I have had two projects with audio sync problems pretty similar to most of those affected. My project is a little over an hour long and it has a sync problem beginning 38 minutes into the project (audio is ahead of the video by about a second). After several different attempts to share and export the project (all with the same sync problem) I decided to divide it into two 35 minute segments. The project now maintains audio sync in both segments (and there is a shceulded "intermission"). This will have to work for me until Apple provides a fix. Hopefully very soon.

    Addendum ~

    Seems there is NO WAY to add Music to a PROJECT which has been on the computer for a few days! Get the usual PLUS nonsense in 'gray' area ...the green line indicates audio there ...but NOTHING comes through! Very poor...expected a lot better!

    Thanks for posting this. I thought it was the different camera I used to import footage into iMovie 9.01. I'm detaching audio from the video clips and shifting the audio. This is very time consuming and frustrating. Its a software defect. I would suggest waiting until Apple release 9.02.

    I keeping reading for a reply from Apple proper as to if "they" are actually going to work on this Out Of Synch problem with iMovie 11. And don't even mention Final Cut Express. What a disaster. S.L.O.W. It took me 3 days to edit a half hour short. It took me 50 minutes on iMovie 8. The exact same project. This is improvement? So till further notice. Back to iMovie 8 till my G4 explodes.

    I agree, it's not, although what I have experienced of it was less severe (in 9.0). It just got worse with the 9.01 update. (See the separate thread on this.)

    And I am yet another annoyed imovie 11 user who thought that upgrading via the Mac App Store was a fantastic idea. Upgraded from imovie 09 to the current version 9.0.1 and discovered that the audio all my footage was badly out of sync. I have tried contacting Apple but with no success (predictably) and I wonder how long we are going to have to wait for an update.

    Surely Apple are aware of the problem?

    No one seems to want to answer your question which is quite pertinent.

    How is it pertinent? What is meant by media here? What the video recording was originally made on, e.g., tape or disk?

    The media is the digital media that has been ingested into your computer. iMovie works with a great variety of media, DV, AIC, MPEG-4, MPEG-2 in all sorts of different frame rates and frame resolutions. It would be pertinent to know if this is happening across all formats or to specific formats. That's one of the reasons I asked you about the drift factor. Your messages seem to indicate that the drift is quite small in 9.0, which can be explained as Steve Mullen did. The drift in 9.0.1 seems much more substantial so possibly a different cause, possibly not happening to all media, possibly not happening to all media equally.

    Thanks. I didn't realize those were called media. I have been calling them file formats or something like that. I had thought of CD-ROMs and 8 mm video tapes as media, namely the things on which content is stored, or through which it is made available.

    It would be pertinent to know if this is happening across all formats or to specific formats. That's one of the reasons I asked you about the drift factor. Your messages seem to indicate that the drift is quite small in 9.0, ...


    It's much smaller. It's still a problem, however. My guess is that it can be mitigated by dividing long events into smaller ones using MPEG Streamclip. But I haven't tried it out.

    ...which can be explained as Steve Mullen did. The drift in 9.0.1 seems much more substantial so possibly a different cause, possibly not happening to all media, possibly not happening to all media equally.


    I'm no expert, to say the least, but my guess would be that the sound synchronization problems of versions 9.0 and 9.01 (of iMovie '11) have a common, or related, source, and that it has something to do with the capacity for sound modification within clips that was new to iMovie '11.

    My initial medium has been DV. I presume it doesn't matter what medium it gets converted to, but just what it started as in digital form.
