Photo Booth audio and video out of sync

I've had this same issue (audio & video out of sync in Photo Booth and iMovie) and just spoke with Apple Support. They confirmed it is a system-wide issue on all Macbooks running Mountain Lion and are writing a Software Update that will fix it. Should be available within few weeks.

I don't believe it! I have an Early 2011 MacBook Pro but I also have a late 2009 iMac same issue. I wouldn't hold my breath because it's been like this since Lion. When did Lion come out 10 months ago?

I noticed this problem after upgrading to Mountain Lion. I went into the Disk Utility and Repaired Disk Permissions on Hard Drive. The problem is now fixed.

Sadly I've tried repairing Disk Permissions and it makes no difference... First recording syncs and any thereafter don't! The only way to get them to sync is to exit out of photobooth after each video recording.... Surely there must be a better way... Please fix Apple!

I also have the same exact issue. I just bought my first Mac computer ever....the MacBook Air...one month ago. I was so excited about the having Apple's superior technology for video! Now I've been going through this crap. About to try all the solutions recommended above.

I also have another issue...with I try to upload a video directly to youtube using "Record from Webcam" it makes the audio sound choppy like a robot. Anyone else have this happen? Thanks.

Thanks! That fixed my problem!

thank you so much.

I have a 27" Imac that I purchased in November 2011. It had Lion installed and I recently upgraded to Mountain Lion. I only tested Photobooth once when I first had the machine and it worked. Haven't needed it since till now. I tried recording and had the same issues as everyone in this string. I resolved it simply by quiting Skype, Itunes and VLC player. It seems to have done the trick as I have done 3 short test videos and all ok. I had to force quit Skype but I think closing an app which shares the built in video camera and mic did it.

Yeah well, try doing one LONG video (5 minutes or longer) and the synch falls off. It's messed up Apple has never resolved this silly little program.

I just spoke with an Apple Care tech about the out of synch audio issue in Photo Booth (they had never heard of it at the Apple Store), and he came up with an easy fix:

1. Go up to the upper right corner of your screen and click on the Spotlight icon and type in "audio." The first result should be "Audio MIDI Setup." Choose that.

2. When the Audio Devices window opens, you should see two choices in the left column. Highlight "Built-in Microphone."

3. In the right window, choose the "Input" tab (the other is grayed out).

4. Under "Source: Internal Microphone" you should see two drop-down boxes next to the word "Format." In the left one, choose "44100.0Hz"; in the right, select "2ch-32 bit Float."

That fixed the problem for me. Good luck.

I tired using a floating point interger--not much difference.

I agree this is something Apple needs to address as the issue makes the video function in Photobooth useless.

Has everyone reported this to Apple via phone or website instead of going on and on about it here? That's the only way it'll be fixed. There are no true solutions here!

I actually prefer to use the built-in camera through iMovie. Not only are there no synch issues, but the camera does not reverse the image as it does in Photo Booth. That's so annoying.

The principal drawback of the iMovie approach is that it's more complicated and time-consuming.

I have all three of those

Thank you for the instructions, it solved the mismatch! Shared with a friend that had the same issue.
