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

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!

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...

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,

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.

Audio and Video are Out of Sync

Hello,
This seems to be a reoccurring problem for me and I'd love some help getting it resolved once and for all. After capturing footage, the audio and video are out of sync in the clip AND when I drag it to the timeline. When I go through each part, it looks like the video hesitates often, which seems to be causing the misalignment of audio. But, once it is moved into alignment, it goes out of sync again throughout the remainder of the one hour video.
I'm capturing through a Canon Optura 50 Mini DV and editing with FCP 6.0.1. I have checked that the audio mode is set to 16 bit on the camera, and the capture settings have the audio rate for 48 KHz.
This same problem occurred when I was capturing another event last week.
PLEASE advise. It won't get aligned even if I take the hours and hours to move the audio left and right frame by frame.

Audio and Video are out of sync after time remaping.

After I did the time remap,audio and video are completely out of sync.
I don't know what I did wrong.Please HELP.
I did a short video(43seg) to explain myself better
http://www.youtube.com/watch?v=X0PQEoZvGbk

ha. having the video is killer. there are a couple ways to do this. i'd recommend using the blade tool (tap b twice to get the one that cuts all tracks), make a cut through the audio and the video at the points where you want it sped up, then right click the clip itself (which should be linked with audio and video) and then just set it to whatever speed you want. it'll have the same effect. you might have to adjust boundaries or you can select ripple.
alternatively, it looks like you just needed to do the same thing to the audio that you did to the video in that clip you uploaded. you can always relink things by selecting the audio and video and hitting cmnd+L.
hope that helps.

Premiere Pro CC: audio and video is out of sync after export

Hi folks! I downloaded trial version of Adobe Premiere Pro CC. Captured gameplay with bandicam in Motion Jpeg Format (as advised) 30 fps and made a 40 minutes lenght clip. But there is an issue: in my project audio is synchronized with video, but when i export - it's lost (and i think to further we watch video, the bigger is the synch gape between audio and video, in increases gradually). I tried various formats, tried to use option "delete rendered files" prior to export, tried "match source" option, tried to choose various drives for exporting - nothing helps.
Help, how to solve this problem?

Handbrake is a free-download program that takes variable-frame-rate footage and converts it to constant frame-rate. VFR to CFR, if you will.
Going back to your reply to my first post, you noted there had been some kind of "hardlimit" to 30fps that you hadn't chosen. I'm guessing that would have made this track CFR, and what you've got instead is VFR. So you might try recording another bit after selecting that setting to hardlimit the frame-rate, and see if it works better through PrPro to export.
Next ... so, you've got a 30fps probably VFR video track, and it appears a WAV file is your audio ... was that produced by the Bandicam program while it was recording your program? Or is it from another source and you pasted it into your sequence?

Audio and video are out of sync when exported.

I've been trying to export a clip from a sequence in fcp. I've marked in and out points, and use the export using quicktime option. And each time, the audio is out of sync with the video.

Yea it still won't let me post images, so here are the settings:
Sequence Settings: Frame size: 1920x1080 HDTV 1080i 16:9
Pixel aspect ratio: square
field dominance: upper.
Editing timebase: 30.
Quicktime settings:
compressor: H.264.
Quality: 100%
Audio Settings:
Rate: 48kHz
Depth: 16-bit
Config: Channel Grouped
Item Properties: comicsonspot.MP$
Type: Clip
Creator: Quicktime Player
Size: 1.7 GB
Tracks: 1V, 2A
Vid Rate: 60 fps
Frame size: 1280x720
Compressor: H.263
Ok, there's a bunch more settings, let me know if you need any other info. Thanks again!

Audio and video are out of sync in I Movie.

Thanks for the last tip, miT. Everything worked out great transferring the TS files through to IMovie. The only hassle now is that the audio precedes the video by about 5 seconds. Is there a way of fixing this, or should i be transferring smaller bits (i had a chunk of about 2 hours, of which only the last 5 minutes is where the audio matters. The stuff before that was all old 8mm stuff from the forties & fifties). I'll try to monkey around with it some more.

With your big 2 hour clip in MPEG Streamclip, move the cursor to the start of the 5 minutes that "matters" and press i. Then move the cursor to the end of this 5 minute section, and press o.
Then File/Export Using QuickTIme in Apple Intermediate Codec. See if that helps.

Upon export, audio and video are out of sync.

While editing, my cuts are lined up with beats in the music, but after export they shift approximately 5 frames, making my cuts appear later.
The Sequence settings match the clip settings at 23.976 fps, and i've tried just about everything I can think of to fix the issue.
I've reverted back to previous Autosaves of the project, tried numerous export settings, separate and new projects, different machines, but nothing seems to work.
At this point I'll take any and all suggestions.

Please UN-check the "Frame Blending" box, that is only used when changing frame rates. The source and export are both 23.976, so that can only cause issues (blurring between frames with motion). Also uncheck "Max Render Quality", that is used for SCALING, such as 1080 to 720, or HD to SD. Your source and destination are both 1080p.
Rule of thumb - do NOT check boxes unless you really know what they do and the results they provide - the DEFAULT settings are there for a reason ;-)
Also, I never use "Match Source" - rather, figure out where the video is going (Blu-ray, web, device, etc.) and find an appropriate PRESET - there are tons of them under "H.264".
I'm assuming the video source is also 23.976? If source doesn't match sequence settings, that can be an issue with sync.
Try exporting entire sequence rather than In to Out. Try EXPORT rather than Queue.
Last thing, what is the source of the video footage? Some phones use "Variable Bitrate" recording and Premiere is not equipped to deal with that very well.
Thanks

When streaming Vid with flash player, audio and video are not in sync

With Flash 11.6, audio and video are not in sync. Video is slower. Using Firefox 20.0.1

Recent crashes of certain multimedia contents (this includes Youtube videos, certain flash games and other applications) in conjunction with Firefox are most probably caused by a recent Flash 11.3 update and/or a malfunctioning Real Player browser plugin.
In order to remedy the problem, please perform the steps mentioned in these Knowledge Base articles:

K900 audio and video are not in sync.

Hi All,
New entry in this forum. I have this K900 phone and i think its an amazing piece or art. But not without its problems though. A perennial issue is when I am playing a video file, initially it plays smoothly but eventually the audio and video are not in sync. Dragging the slider left and right or pausing and playing agian only worstens the issue.
Have any body ever faced such issues? If yes kinldy share a solution if any.

Why do my audio and video get out of synch?

No matter what sort of video I'm trying to play: Youtube, a movie on DVD, a movie on an external hard drive, etc, after a short time the audio and video get out of synch with each other. This is often, though not always, signaled by a short audio phrase being repeated (eg: "I don't know, Scully, how about you? about you?"). I can solve the problem by quitting the app and starting it back up but it will eventually screw up again.
I'm using a MacBook running OS 10.6.8 with a 2.26 GHz Intel Core 2 Duo processor and 4 GB 1067 MHz DDR3 memory.

The first thing that we need to know are the properties of what you are putting on the Timeline. What works in another software does not necessarily work in Premiere Elements. Each program has its own supported formats.
a. What is the file extension for this file? .MOV or .MP4?
b. Does the iPad describe it as 1080p or 720p?
c. If you open Premiere Elements 12 and go to Edit Menu/Project Settings/General, what do you see for Editing Mode, Timebase, Frame Size, and Pixel Aspect Ratio, even if those field appear to be grayed out.
Two immediate troubleshooting avenues are going to be in the direction of...
a. Project settings not set up to match the properties of the source from the iPad. Then we would start a new project and set the project setting manually before importing your video. Details for manually setting the project preset are in the following.
ATR Premiere Elements Troubleshooting: PE11: Accuracy of Automatic Project Preset (New Project Dialog) Setting
b. The iPad video being recorded with a variable frame rate instead of a constant one...the remedy then would probably be to take your video in a program like HandBrake to change the variable to a constant frame rate. And after that, import the corrected video into the Premiere Elements project which has the correct project preset (preferably set manual to assure the correct result).
Please see what you can put together in the way of video details, and we will sort this out.
Thanks.

Strange export result in FCP 7- audio and video output not in sync anymore

I have a problem exporting edited videomaterial. After export audio and video they are not in sync anymore. There's a difference of 8 sec when exporting audio and video separatly. Movie is total 61 min long.
Video and sequence settings are HDV1080i50, 25fps, 48khz, 16 bit, mono.
What could that be ?

Well now that I look at all the clips in FCP more closely I see some clips from the same tape are in sync and others are out of sync. And one section of tape which I captured twice was in sync on one clip and out of sync on the other. So it can't be the tapes.
Maybe the sync problem is caused by not coordinating the tape playing and FCP capturing properly every time! So I will try re-capturing the problem sections of tape.

Audio and Video not playing in sync

After importing my mp4 video into Premiere Pro, the audio plays perfectly, but the video is out of sync and plays as if though it's in slow motion.
I've been using this software for about 4 months and have encountered this problem within the last few weeks.

Thanks for your prompt response, John.
Here are the details:
Video was recorded on Canon Vixia HF R400 HD 53x Camcorder using the automatic setting (no customized settings whatsoever).
I inserted SD card into computer (PC, using Windows 8 operating system), right click to import media file to Premiere Pro CC.
When I attempted to play the video in the Source window, I notice that audio played perfectly, but video was playing EXTREMELY slow. In fact, at times the video was at a standstill and wasn't moving at all.
Here are the result from the MediaArea.Net analysis.
