Video and audio not in sync. Other answers here do not help.

My audio and video are not in sync in many streams but some are OK.
I do not have any extensions, add-ons and I am using the default theme. I have disabled hardware acceleration. I am now running in Safe Mode and the problem persists.
The video and audio sync for the first few minutes and then they work their way futhter and further apart, usually several seconds out of sync. I don't think this particular situation has been covered in the other posts.

You can check for problems with current Flash plugin versions and try these:
*disable a possible RealPlayer Browser Record Plugin extension for Firefox and update the RealPlayer if installed
*disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)
*disable hardware acceleration in the Flash plugin

Video and audio not in sync

Anybody else experiencing video & audio not in sync since upgrading to Lion? I have a MacBook Pro 15-inch, Early 2011 with
AMD Radeon HD 6490M 256 MB graphics. I mostly stream You Tube, Netflix, & news videos and occasionally watch movies I have in iTunes or on DVD, and since upgrading, I've seen out of sync video and audio in every one of these situations. Sometimes it starts out OK and then slowly deteriorates. Other times it just starts out that way and stays that way. Happens with all browsers as well as iTunes and DVD Player. Tried a few Google searches but haven't come across any postings reporting this with Lion, so I thought I would try here. Thanks for any confirmations and/or pointers to a solution if there is one.

Ahh...boom. I have it too. Forgot it was even there. I had it turned off back when running Snow Leopard since it was glitchy. Apparenty, I somehow reenabled it and wasn't even aware it was on since its volume was turned down. After disabling it, all video & audio appears to be in sync.
boom...the sound you'll hear as I nuke it from my system.
Thanks efrancis76 for figuring this out. Much appreciated!

Video and Audio not in sync after capture

Hi there,
This is probably a common problem, I have trawled the site but can't seem to find and explanation for it.
I'm capturing vide/audio into final cut pro from my SONY DVR. The video i have streaming into the sony DVR is from a small covert video device which records video/audio onto an SD card. SO I'm running that into the DVR and then DVR is outputting that as DV PAL firewire (uncontrollable device).
I'm capturing the 40 minutes of video as one clip, and when i drag it into the timeline the audio and video are WAY out of sync. Is there a simple reason for why this is happening?
It's almost as if not capturing it right.
I hope someone can help,
Thanks in advance.

It is interesting that you are having this problem. I recently purchased a brand new Mac Pro (a week ago) and I am using Premiere Pro and it is doing the exact same thing. I mean this video and audio is REALLy out of sync. I tried capturing an hour at a time, and 30 minutes at a time. Still, no luck. I was debating on getting Final Cut, but after reading this post I am rethinking not only Final Cut, but using Apple all together. Part of me thinks that it is not a Premiere or Final Cut problem but a Mac OS problem. But hey, what do I know. I only edit for a living.

Video and Audio not synced on .mov file in final cut, but perfect in QT!

I recently just captured a miniDV tape onto final cut. I captured it in 23.98fps. After I captured it and opened it up in final cut's sequence, the video and audio was not synced at all. it's way off and even when i try to move the audio around on the timeline and get one voice synced up, about a minute into the video it's off again.
i tried opening the video in quick time under the captured scratch folder, and when it plays in quick time, it's perfect. there is no sync problem at all. only when i open it in final cut is there a problem.
does anyone know how to fix this or what is going wrong?!
HELP ME

well i mean we recorded it in 24PA, which is what we've been doing for this project of ours. And when we go to capture in final cut we choose the Advanced Pull Down setting. So in the end, our video is in 23.98 fps.
I just thought I'd mention that just to give more details. idk if it's helpful or not

Video and audio not synchrone with apple tv after update mountian lion on macbook pro

i have a problem with my apple tv. after i bought and instaled mountain lion on my mac book pro i have trouble with apple tv and my laptop. when my laptop conects with apple tv most of the time my wifi doesnt work on my macbook but on my apple tv it stil does work. when it does work and i play a movie of my own by using itunes the first second the video and audio is synchrone but after that audio is at normal speed but the video gets behind. and i am getting sick of it. does sumbody reconize the problem and can help me with this problem?????

Same issue here- I can airplay my amazon prime library just fine from my iphone 5 but on my macbook- (mavericks, 15 inch 2013 retina with quad core i7, nvidia 650 M and SSD) it just sputters and lags.
I have noticed web video is considerably worse than local content, giving me pauses of up to 2 or 3 seconds in which video stops but audio continues in the amazon player. Youku video, however, seems relatively stable. Our subscription speed is 25 mbps, so that should be plenty to stream SD video from Amazon and doesn't account for why it would be nice and stable from the iphone, but not the mbp.
Playing light, locally hosted steam sidescrollers like Limbo is better but gives periodic drops in framerate on the Tv. when mirroring the framerate remains steady on the MBP screen.
Games airplayed from my iphone seem relatively stable, though with a noticably lower framerate on the TV than on the phone.
It seems these issues have abated considerably since yesterday's Apple TV update, but are still curious nonetheless and I'm not sure that the update yesterday was specifically meant to address those issues or if I'm just getting a time with less network interference now.
Comcast recently installed a new router/modem/phone combo, replacing our old separate modem and router setup. I'm going to test if putting the network on a different channel helps.

Video and Audio to "snap-to" other video and audio

My problem is simple, but annoying. I used to be able to drag video and audio and when it would come close to contact with other video and audio, it would automatically "snap" to the end of the video and audio.
Now, the video and audio does not "snap" and this causes me to loose time editing. How do I fix this?

Video and audio not linking

Hello all:
I'm using FC 4.5 and for some reason the video and audio has decided to no longer link together... even though they are captured as merged files. The Stereo Pair and Link command under the Modify tab seem to have no effect (even though the clips indicate that they are - a line runs through them). Only recently started to occur. Real pain the in the buttocks. Any ideas out there?
Thanks
Adrian S

If diligent work with the link and stereo pair t'aint

Quick Time 7.67 video and audio not playing in CourseCompass MyMathLab

When I first used MyMathLab through Course Compass, the video and audio played with the digital picture broken up. Since then it stopped running the video and audio. I have tried uninstalling and reinstalling Quick Time more than once without any change. Now when it is trying to load,I just get white screen with Q logo and an arrow running across the bottom of its window.

I forgot to mention I use Firefox. I just updated to Firefox 3.6.9 today. The quick Time problem already existed before I update Firefox.Is there a problem with Quick Time being compatible with Firefox?

Video and audio not linked after upgrade to cc

I recently upgraded from 5.5 to CC. Every project that I know open, the video and audio are no longer linked. I right click and enabled is checked. It's a huge pain when editing!!
Another starnge thing, after I reopen a project I'll notice that the audio tracks duplicated themselves??

You're welcome.

Video and audio not in sync (ALSA underrun occurred)

Hi, after a recent system upgrade (upgrade log here http://pastebin.com/1gRwexFr), video and sound are not in sync anymore. The problem occurs in mplayer instantly, and in XBMC after a while (the audio is slowly getting out of sync). The error message I get continuously in XBMC is "ALSA lib pcm.c:7339:(snd_pcm_recover) underrun occurred". The error I get in mplayer is "[ac3 @ 0xf46b40]frame sync error" I did another system upgrade and the problem persists. I'm using Terratec Aureon 7.1 external sound card and linux 3.3.3-1-ARCH. I'm not using pulseaudio, just alsa.
EDIT: I downgraded (sudo pacman -U linux-3.2.13-1-x86_64.pkg.tar.xz linux-headers-3.2.13-1-x86_64.pkg.tar.xz linux-api-headers-3.1.6-1-x86_64.pkg.tar.xz dbus-1.4.16-1-x86_64.pkg.tar.xz dbus-core-1.4.16-1-x86_64.pkg.tar.xz glibc-2.15-7-x86_64.pkg.tar.xz) and the problem seems to be gone. I'm suspecting the kernel upgrade broke it..

See what buffer size you end up with. Start mplayer, and run:

Video and Audio Not Sync

When I import the video from my camcorder(JVC GR-HD1U) via firewire the video and the audio do not match. does anyone know how to fix this.

welcome Delta X to the  board...
long imports (>15 - 20min) of NTSC content get out of sync, due to some specs trouble (NTSC has 29.95 fps, but audio is an even 48KHz... that "shifts" the audio... known NTSC problem...)
there's a fix on the web, never tried my own, me PAL country:
Movie out of sync fix
I've read reports, to import just smaller segments of your tape (see iM's prefs) could solve the problem too... give that a try...

Video and Audio not lyncing

Help! I shot a video on miniDV. When I bring it into final cut express 4.0 the first 25 minutes of the 50 minutes is synced perfectly audio and video, and then all of a sudden for no reason the audio and video are not syncing properly. It is not because it's not linked, because just when I preview it in the viewer it does the same thing. HELP HELP HELP! Thanks!

Open the clip in QuickTime and see if it does the same thing there. If so, then there was some kind of glitch at that point in the capture. This happens sometimes and you might consider recapturing the video.
Does the sound go out of sync & stay out of sync by the same apparent amount, or does it drift further out of sync as time goes on?
If the sound doesn't drift (meaning, it just goes out of sync by a fixed amount, say 1 sec) ... and the point where it goes unsync'd is not critical ... you might consider razor cutting your clip at that point in the timeline, unlinking the audio from the video in the portion of your clip that is out of sync, turn on audio waveforms, and then slide the audio clip back into sync with the video. It will take some noodling and you will probably have to zoom in on your timeline, but it can be done. Best to find some place in the clip where there is a sharp sound associated with a motion (a door slamming, for example) - that will make it easier to resync the audio with the video.

Sound for recording video and audio not working

I have tried everything to get the sound to work. I have reinstalled the audio driver. When I go to soundrecording.exe to see if I can record sound it gives me a message "An audio recording device cannot be found." Please help this is driving me crazy.

well, since people can hear you on a call, it's not a hardware problem with the microphone.
It appears to be something wrong with your recording apps -- the camera (in the case of video) and whatsapp.
First attempt would be to:
a) install another camera app with video capability and see if IT will record audio. and
b) uninstall and reinstall whatsapp to see if that fixes the problem.
If that doesn't work, to a backup, then try a hard reset and re-install the apps one by one, confirming that recording works after each install.

Video and audio not sync when i play all forms of video. from music videos, to tv shows. but they play perfect on my iPod. and tv shows display out of order on iPod, but in correct order on iTunes/computer. I even ran a virus check just to make sure.

audio and video do not syncronize. all forms of videos. music videos to tv shows. what do i need to do the syncronize them again
they are in sync on iPod, but not on computer.
another issue that might be from the same cause is, the order of episodes of the tv shows i have downloaded, they appear in order on computer, but on iPod they show out of order.
any tips on how to fix this would very much help.
thank you.

Welcome to Apple Discussions!
An old version of iTunes will cause this and mess up the videos on your iPod. Always make sure you always use an up-to-date version of iTunes.
Make sure all the software on your computer is up to date...
iTunes
iPod Updater
Updating iPod's Software
You will then need to restore the iPod and then let iTunes update your iPod and put your music, videos, etc. back onto your iPod...
Restore the iPod

Video and audio not in sync v 7 itunes

since downloading this version when attempting to play previews of tv/movies on itunes the video is slow to play back sort like frame by frame (as well if i buy a tv show). of course the audio is all out of sync as well. the sound is perfect and the picture clear. this never happened in the previous version of itunes... any ideas?

Video is better for me since disabling the Direct3d acceleration as described in the FAQ, but it's still not up to where I'd like it. If I right click on a podcast and select "Show in Windows explorer", and then open the video in another player that supports MP4, like media player classic, or VLC, it plays much better, and it has the screen refresh synchronization that's inexplicably missing from the Windows version of QuickTime.
