Video plays out of sync when viewing in Quicktime

I have rendered out a H264 file using the vimeo hd 1080p 23.97 preset. The file plays wonderfully in windows media player and out of sync in Quicktime player. Also when I upload to Vimeo there is one section that is out of sync, and that is what made me play it on my computer using quicktime and the windows media player. Then I noticed it plays great in wmp and not so great using Quicktime. What can a person do to remedy the sitiuation?
Thanks,
John Lorince

Hi Jim,
Thanks for replying. I uploaded the same video to Youtube with no sync problems. I deleted the video from vimeo. This is the first I have seen this with.
Thanks,

Video plays out of sync with Flash version 11.6.602.180 in Firefox

I've been receiving multiple reports that some videos plays out of sync with Vimeo's Flash player in Firefox, but not in other browsers (with the same version of Flash installed). Disabling/enabling hardware accelerated decoding does not seem to make a difference. Any ideas as to what might be causing this issue?

This could be multiple issues, but the first thing that comes to mind is the protected mode feature in Flash Player for Firefox. We've made significant improvements in our 11.7 beta and I'd recommend giving this a try:
3/19/2013 - Flash Player 11.7.700.146 Beta
If that doesn't help, or you can't update to the beta version, try the steps outlined in this post:
How do I troubleshoot Flash Player's protected mode for Firefox?
In particular, I'd recommend temporarily disabling protected mode (for troubleshooting purposes only) to see if that addresses the issue.
Thanks,

PLEASE HELP!!! Some videos are out-of-sync when played on iPod

I bought a brand new black 30GB video iPod yesturday, I was excited as ever, but now I would convert a bunch of videos, they would play perfect on the computer, but when I put them on the iPod some of them would be out-of-sync. What is going on here? Is my iPod broken? I tried taking it back to firmware 1.0 and it's the same thing. Somebody please help me!

You most likely need a new converter. try videora http://www.videora.com/en-us/Converter/guides.html

Why is the audio on my video getting out of sync when it is imported into itunes?

Hello,
I have videos in the MP4 Format, and have imported them into itunes. However, during playback in itunes, the audio gets more and more out of sync as the video plays. By the end of the film the audio can be 5-6 seconds out!
What's strange is that the source file, played with quicktime or Windows media player, is fine and works perfectly.
Why is the audio stretched once it is imported?
Thanks,
James

I have the same problem.
Motherboard: Gigabyte GA-MA785GPMT-UD2H
Chipset:
North Bridge: AMD 785G
South Bridge: AMD SB710
Video: Integrated ATI Radeon HD 4200
HDMI Audio through the HDMI port out to the TV.
Tried on Windows 7 Pro 32bit and Windows 8.1 Pro 64bit.
Tried with the integrated ALC889A audio device enabled and disabled (It seems that the video card drives the HDMI audio device though, because it still appears in Windows even if I disable the Audio device in BIOS).
Latest iTunes and drivers installed.
I have already tried all sugestions about matching Windows Audio settings to iTunes settings (bit depth, frequency rate).
Apple, any suggestions? I'm not having a great customer experience after buying a pair of HD movies in iTunes.

Audio Drifting Out Of Synce when Exporting to Quicktime

Using FCS2 and all material is HDV 1080i60 with audio 48k. Everything in my sequence plays and renders fine and is in sync. When I export to quicktime movie using current settings the sound goes slowly out of sync so that by the end of the project the sync is horrible and the actual project is short 11 or so frames??
Any suggestions?? I have always done this in the past with no problems but since switching to FCS2 I have had nothing but problems when this comes up.

I had a similar problem when I exported a 20 minute video to an .flv Playback looked and sounded fine but the .flv file direct out of Final Cut was out of sync with audio. I finally used the Render Manager under tools to remove all renders for that sequence and then just re-rendered in one shot. That export was clean. I had tried to break renders and re-render them but it didn't work, but the Render Manager seemed to fix what ever caused it. I haven't noticed again since on any other projects. Good Luck.

Audio out of sync when playing HD content

Hey
I've got an issue with the audio gets out of sync when playing some HD content. I've tried to make sure the video is stored on the Apple TV so it can't be the network connection.
I've also tried a full reset of the unit, but still no luck.
But it's all video clips that has this problem. Even though they encoded the same and so on, some videos audio get out of synced and some don't.
Also have a problem with m4v files locking the ATV (and iTunes for that matter), but renaming it to a mp4 file seems to solve it. But if someone has a fix for that as well I'd much appreciate it.
Many thanks in advance,
Jeaz
EDIT: I have tried to use component cables instead of HDMI, but the problem remains. Of course also tested the video on my Mac and no problems. A quick pause and resume usually solves it, but only for a minute or so.

What sort of specification is the video content? Is spec too high for AppleTV.
It may be that it's some kind of bug in AppleTV's playback, that the Mac does not exhibit, or an issue with encoding that causes a problem only on AppleTV.
If you are encoding video and using same as source for the frame rate, it may be better in some cases trying explicitly to specify the frame rate required in case automatic frame rate conversion is introducing some kind of timing issue. Test a short clip to see.

Video + audio recorded in Quicktime X is out of sync when used in iMovie

I have recorded video in Quicktime X. When I try to edit it in iMovie, the audio and video are out of sync. They are in sync if I play the video in Quicktime. I am using the latest version of iMovie '11. Anyone know how I can fix this?

You should not HAVE TO but did you try extracting out the audio? This has been a issue for a long time. I am not sure why you never see this problem in Final Cut but it rears its ugly head in iMovie all the time. What do the call it now? Oh yes... detach. Select the clip then Clip -> Detach audio and line it back up.

Audio/Video out of sync when exporting to MPEG4

I am working on a project that is being edited on FCP 5.1.4
Anyhow, there is problem when exporting to MPEG4- the audio/video is out of sync.
Sequence settings show 29.97 editing base with 48 mhz sound, which is the same as the MPEG 4 settings, but they are not in sync. Anyone encounter this problem? I've never had this problem before previously.
Thanks

Hi Harm,
last time you suggested the same but I wouldn't know how to take the BM card out of the equation. I only have on station. If I export to Beta SP there is no problem.

My videos play with video/audio out of sync in itunes, what gives?

All of my itunes video library, including those purchased from the itunes store, play with the video/audio out of sync. However, if I use Quicktime, they play fine. I just noticed this recently with the latest update to itunes.

I found the solution using google search. Basically you have to downgrade your itunes software to version 10.7 and rebuild your library. Just type in iTunes audio/video out of sync on google search and you will find the solution I am talking about. I didn't think it would actually work because supposedly apple knows what it's doing but not in this case. Why they would put out a new version of itunes that makes none of your videos play right, even ones you purchased from itunes is beyond me but I'm sticking with version 10.7 for as long as I can.

Audio Video *still* out of Sync in iMovie '11 (9.0.3)

There are several similar threads about this issue, with the final solution being to upgrade to a later software version. I am using the current latest update of iMovie '11 and am having terrible issues with audio syncing.
All of the affected clips are direct-to-iMovie captures via iSight camera and either an external UBS mic (Snowball) or internal mic. The problem happens either way.
Clips range in length from 45 seconds to 15 minutes. Out of say, 20 clips, 15 will be affected, some will be perfectly fine. There is no consistency as to when the syncing drifts apart, but it gets worse over time. Many of the clips drift out around the beginning (between 10 sec and 2 min in) and back in sync 30 seconds or so before the end. When the clips resync it doesn't seem gradual... nothing seems to change, but all of a sudden they're perfectly matched again.
It seems to be consistent that the audio is ahead of the video, but the audio itself doesn't sound any faster (going by the pitch) and the video doesn't look slow.
This is definitely a problem in iMovie itself, NOT in the import. Every single clip is perfectly synced when I view the raw .mov file in Quicktime. Clips export to web perfect out of Quicktime, but are out of sync when exported to iMovie.
On that note, I had one clip that was initially out of sync all the way through change to being back in sync toward the end after restarting the app. (No other clips changed.) I also had one clip speed up to chipmunk speed after a minute and a half and pop back to normal after 2 minutes. I left iMovie open, didn't close or sleep the machine, just switched to Quicktime to edit there... when I switched back to iMovie that clip played back normally (but no other ones changed.)
- I've tried exporting the Quicktime into a brand new .mov file and reimporting into iMovie as new footage; still no dice.
I've tried detaching audio, this doesn't work. Syncing each clip by hand via cuts is nearly impossible, as there are hundreds of clips, most of them 2 minutes long, and the drifting is so bad that piecing one 45 second clip back together resulted in dozens of audo cuts and nudges, and it still looked bad. (This is an oral history project, so every video is a close-up shot of someone speaking.) I have been working around the bad clips by trimming in Quicktime, but a many of them need internal trimming and audio manipulation that Quicktime can't do... and it shouldn't need to do it, because I have iMovie. This is driving me insane! Is anyone else experiencing this? Any thoughts/ideas?

I too am facing the same issues and trying to look for good alternatives. Ugh.

Video & Audio out of sync after update

Ever since I updated my MacBook Pro to OS X Yosemite v10.10 last week, all videos are out of sync with the audio. It wasn't just on Safari while playing YouTube videos or DailyMotion videos, but also when playing videos files on my computer. For short videos, the audio is just a second ahead or behind the video, but for long films it can be minutes apart.
Does anyone else have this problem? Can anyone tell me what caused this and how can it be solved? Thanks so much!!!

I have the same issue and it started 3 days ago. This happens with anything I'm watching, netflix, huluplus, youtube, crackle, anything that has audio and video. The biggest issue is that it's also affecting iMovie and Final Cut pro X. This is a MAJOR issue given that I make a living editing video. I hope somebody can find a solution for this issue.

Audio and video is out of sync!

when I record audio and video together with my isight built in camera on my macbook pro with either quicktime pro, photobooth or imovie, when I play the clip back the audio and video is out of sync! like watching a kung foo movie. I've tried everything, I've taken my book into see a "Genius" at thew mac store and he said to me that the isight is made really for video conferencing and is really not supposed to be fully in sync? Uhh thats weird, so mac makes a product and puts it on all their laptops and it only sort of works?? I've been on the phone with apple care, did a bunch of things like disk utility repairs on permisions, then used the startup disk to do another permisions repair. I've uninstalled quicktime pro and re-installed it a couple of times? If anyone could give me some advice that would be great! I'm a little frustrated as you can probably see! thanks
cheers

Welcome to Apple Discussions, m
See if any of the suggestions offered here reduce your sync quality problem enough:
http://discussions.apple.com/thread.jspa?messageID=7089133&#7089133
If, after making certain that your Mac is running well, has plenty of free space on the correct drive, etc., your sync is still not close enough, you can manually re-sync any parts that are unacceptable to you using either QT Pro or iMovie.
If you check carefully, you will see that not even pro video is always perfectly synced. It is a lot of work to get things "nearly perfect," but, with a bit of practice, it doesn't take long to get things "close enough" for me.
I use the same simple process with either QT Pro or iMovie, so you can use whichever you find easiest. Whichever you use, keep the original AV clip safe and *_work on a copy_* in case something goes wrong.
If you do not already know how, here is my process, but you can adjust for your workflow:
(1) Copy of the audio track.
(2) Add the audio track copy to the AV file.
(3) Silence the original audio and work on audio copy.
(4) Insert small blank audio clips (or split and slide if using iMovie) if needed to make the audio later.
(5) Cut small bits out of quiet parts (or split and shorten in iMovie) if needed to make audio sooner.
(6) Repeat until satisfied and delete any tracks no longer needed.
(7) Save the adjusted AV file.
(8) Enjoy!

Updated FCP 5.1 to 5.1.2 - Audio and video now out of sync

I just noticed in my software update that FCP needed to be updated. So I updated the program.
Now when I open exisiting projects the audio and video are out of sync even though they appear perfectly in sync in the timeline. Has anyone else had this problem? The problem also persists when cutting clips in the timeline. I will use the razor tool to make the cut and I cut the clip on a ceratain frame in the timeline and then in the viewer the clip was really cuts a second or two later. Does anyone know what is going on?
Very furstrating to say the least. Any help is much appreciated.
Thanks,
Clay

I am still wondering why you're recommending that I use an external drive for this project.
Because the internal has more than enough to do running Mac OS X and the applications. It is constantly writing files. While DV video is at the lower end of the scale, it is still asking a lot of the drive's read and write head.
I always used external drives, but we had many problems with delays and processing problems.
At the very least, you should be using FireWire external drives. USB is no good for video as it delivers data in packets, not the sustained stream that video needs. The drives must also be formatted as Mac OS Extended. Windows FAT 16 of FAT 32 formatted drives have file size limits of 2 and 4 GB respectively. Anything larger is segemented and can cause problems on a Mac.

Photo Booth Audio and Video are out of sync?

Hi. So there is this glitch that when I take videos on Photo Booth the audio and video are out of sync. This started after I upgraded to Mountain Lion, and since I use Photo Booth a lot, I really do care. Is there anyway that I can fix this until Apple fixes this bug? Thanks.
Extra Info: The first video I took was not out of sync, but after that they got more and more out of sync.

I've read all the forums. It's a big problem for most Photobooth users, Apple acknowledges it, but does not yet have a fix.
The best solution I have come up with is to dump Photobooth (I know - it was a great program, wasn't it? But so was Hypercard) and use Quicktime to make videos. You'll have to spend a little more work savings or exporting, but at least Quicktime is free.
Just open Quicktime Player and under the File menu you'll see "Record New Movie."
The downward slide continues...
