Sound out of sync after iMovie '11 upgrade

I am SO angry. I have just bought a new iMac and a Macbook Pro within the last month (for business purposes) On both machines I am having major problems with the sound being out of sync with the movie. Even when I record with the built in isight the audio is still majorly out of sync. This is ridiculous considering it was supposed to have been fixed with the latest imovie update. I've used imovie for 4 years now and didnt have this problem on my last macbook. What the **** is going on? It's an absolute nightmare especially when I need to use this feature for business. Is anyone else still having this same problem?? I should add I've tried everything I can think of including detaching the audio from the clip...At a complete loss at what to do? 😟

I too am having this and can't seem to fix it. I just spent two hours recording a video only to find that by the end of it the sound and video were almost 2 seconds out of sync. This *****.

I'm having the same problem. New MacBook Pro with iMovie 9.0.4. I recorded a 48 minute lecture with my iSight built-in HD camera. Within 3 minutes of the start of the clip the audio is dragging behind by at least a half second. Then it gets worse from there.

I have iMovie 9.0.4 and my clips (imported long time ago from Sonu cam) suddenly have no sound. Gobblins may be?

Did you get your audio to sync up with your video? I see this was from a few months back.

This might not help much for those who need the greenscreen and movie speed control, but for videos that don't need those effects, you can create the movie and then import it into Garageband to fix the sound. It's easy to clip and tighten the sound there. This doesn't help me much, because I need those effects (which, inconveniently, are only available in the newer versions of iMovie). . .

Found this on a similar thread, it fixed the problem for me.

Hi All,

I've been dealing with this sync problem tonight as well and here's what I found that worked.

I noticed that the audio sync was fine when I viewed in Quicktime 7, but not in iMovie. I also noticed there was a small indicator on the clips in iMovie notating that the source clips were in 17 fps, not 30 fps. This is odd because I recorded the clips using the FaceTime HD camera right into iMovie and it never gave me the option for framerate on the recording. Viewing the source video in Finder I also realized that the codec for the source was Photo Jpeg... yuck. Who's choice was that.

Using MPEG Streamclip (free video converter) I converted the source video clip to a Quicktime .mov at 30 fps and using the Apple Intermediate Codec and all the audio sync issues were fixed. Didn't have to optimize, detach, or - most importantly - re-edit anything. Apple's editing systems love Apple Intermediate Codec (AIC), I don't know why they don't import in this codec by default.

So annoying! My audio is way out of sync... I am using the FaceTime camera and iMovie 11... *** Apple. Fix this.

This worked for me! I was having the same problem - audio starts out synced but gets off badly in the middle and is resynced at the end.

Re: iMovie '11 audio sync issues since 9.01 patch

If you play the movie in Quicktime or streamclip the audio is synced all the way through. Open the event file in mpeg streamclip (find this by right click on video in imovie, then reveal in finder), then go File - export in quicktime - enter frame rate 30 (fps) and then change the compression pull down menu to Apple Intermediate Codec. I then reimported this new file into imovie and the audio is great all the way through. Took about 5 minutes total.

I tried this but it has made no difference

Just a quick general comment about audio/video sync: This is a problem that was solved by the film industry more than eight decades ago. And now with all the fancy shmancy computers and software, suddenly it's a major issue. What the donkey kong is going on?

This is how I fixed my own progressive audio sync problem when I filmed a business meeting with my icam through imovie 11 on my imac 10.8.5:

I opened the video in Garage Band. I locked the audio to the video with a button on the upper left hand side. Then I exported that video to the desktop. That fixed my audio video sync problem!

I had tried the Quicktime fix used by some, but it didn't work for me. Garage Band did.

Actually this didn't work for me, sorry. Here's what did:

I gave up! Then I searched for alternatives to imovie and found iskysoft video editor at the apple store. It works just fine!

that's right, I have the same experience, round about 3 or 4 minutes in
