Any video application I use with my iSight is out of sync with the audio.

It doesn't matter which application; Skype, Facetime, Google Talk, or trying to record a live video is all out of sync. The video appears to be lagging behind as I can still see my mouth moving after I'm talking. What's the problem? Sometimes I think I'm stuck in some type of bad kung fu movie timewarp... Someone help me get back to normal!
Thank you!

Hi,
I would start with older threads on the issue

I started from the More Like This box. I choose what I thought would be a likely one then repeated the choice again at that thread as it had some that were marked with the green Solved tick.

IMovie: I uploaded HDV video from a Canon HV20 and then to YouTube. The video and the audio are out of sync. The audio seems to precede the video by a tiny bit which is disconcerting. Any recommendations about how to correct this? Thank you.

I downloaded video via iMovie from my Canon HV20. The video was in HDV. I then published it to YouTube and Vimeo and in both cases, the audio is out of sync: the video precedes the audio by a fraction of a second. The original is fine as viewed in the camera.
Any suggestions as to why and how to correct it?
Thank you,
David

When I watch tv shows in Front Row that I've bought off iTunes the audio gradually falls out of sync with the video. It does not happen with other files that I have converted into mp4s. Any ideas for fixing this? It's a huge bummer...

I too have the same problem. The audio drop out of sync in about 5 sec in not uncommon for the audio to be 30+ sec behind video. Apple needs to fix this!!!!!!!!!!!!!!!! its a joke, my iphone is all messed up after the last update as well. at one time not to long ago apple products and software were top rated, not so much any more, more and more problems are showing up and apple is unwilling or unalbe to fix the many issues. Apple needs to fix the audio sync problem, it not the computer hardware or other software it ITUNES!!!!, there is no workaround other then hitting pause and hitting pause and hitting pause to temp fix the problem.

I want to play video on my computer to make some analysis to frames,the problem that I face ,I can't change video frame rate using labview,but I can change frame rate to the video out of labview using some program

HI All
I want to play video on my computer to make some analysis to it's frames,the problem that I face ,I can't change video frame rate using labview,but I can change frame rate to the video out of labview using some program .
I used IMAQ AVI Read Frame VI
for example I have avi video It's frame rate is 25 fbs ,my image processing code is very fast that can process more 25 fbs,so I want to accelerate video acquisition

Hi abdelhady,
I looked into this further, and reading an AVI file into LabVIEW faster than its frames per second won't be possible. LabVIEW could read in frames faster than 25fps, but because it will be pulling the available frame at that point in time this would just give you duplicate frames. If you want to be able to read in frames at faster than 25fps, you would need to speed up your AVI file before reading into LabVIEW.
There's a good shipping example to show how to read in from an AVI file, "Read AVI File.vi". You'll notice that they add timing to make sure that the while loop runs at the right speed to match up with the frames per second of the file being read. This is to make sure you're not reading duplicate frames.
Thank you,

Video - dialog goes out of sync with video

When I play Movies or T.V. shows on my iTouch the dialog (or audio) gets out of sync with the video. It starts happening after about 5 minutes of play. I close out of the video, re-open it and it's back in sync again for about another 5 minutes.
I had a second generation iTouch and have just purchased a 3rd gen iTouch and it does it on both. It happens on every movie or t.v. show I watch.
Any suggestions?

I really appreciate your help. I tried it with the link you provided and it appears it's the wrong format type. The one I'm trying to convert is a .wmv file. I think that link was mainly for mpegs.
I did successfully convert a 3rd movie .wmv file using videora, so I have to think the problem lies with this one movie clip. What could it be? It plays fine on my computer! The video itself is fine after the conversion too, it's just moving too fast as if in fast forward mode. Then when the video ends (before the music, cuz it's not in sync), the video keeps backing up and continuing from later and later previous spots until the song ends.
If you're out of ideas, I guess I'll try to see if I can find the video somewhere else and download it again (I got this video free from a website). It's super cool.. An F-18 pilot video tapes himself performing aerial maneuvers to the song "magic carpet ride". Darn, I REALLY want that on my ipod!!

Audio out of sync with presentation (not using full motion)

When I preview or publish a project using Captivate 5, the audio is out of sync with the presentation. I am not using any full motion recording, which I know has caused audio/video sync issues in previous versions of Captivate. The audio is slide specific, with a separate audio file for each slide. (In other words, I'm not trying to break a large audio file over many slides.) When each slide is viewed individually -- in the workstation, in the preview window, or in the published version -- the audio is synced just fine. The problem arises only when I try to watch the entire presentation (approx. 10 minutes in length). The audio gradually lags behind the visual. By about half way through the project, the visual presentation is noticably ahead of the audio. By the end, the audio is nearly 4 seconds behind the video. I cannot detect a noticeable change in pitch or speed of the audio, so if the audio is being altered in any way, the alteration is slight.
However, if I use the playback controls to advance to a single slide, the audio is fine for that slide and those immediately after, although it does gradually get off again as the project progresses. (So, for example, if I start the playback in the middle of the project, the audio will only be off by about 2 seconds by the end, rather than 4.)
I have tried various publishing options (although I don't think publishing is the problem, since this happens when I preview the project as well). I have used 2 different computers and also tried viewing the published version locally and streaming. None of these alterations seem to make a difference. By the end of the presentation, regardless of how the project is published or viewed, the audio is several seconds behind the video.
My specs:
Captivate 5
Microsoft XP OS
2 GB RAM
Publishing to .swf
Suggestions?

Hi Mukul,
Thank you very much for your careful responses. Here are the answers to the questions.
First of all, the "slow video" behavior does appear only after adding the slides mentioned in previous post.
1.    I created a “software simulation” project. It IS a capture+audio recording.
2.    Since I recorded the audio while doing screen capture, almost every slide has audio, which is not convenient to edit at all. Is there any other better way that I missed so that we can keep the audio and video at the same step while editing them? As I know so far, either insert silence or delete a little audio to one slide, the audio becomes short, but the slide duration time is still the same as before unless we change that manually which normally is not precise enough to match the audio.
3.    I tried to add the blank slides at where there is a pause of speaking and where they are close to the problem slides. Otherwise, the speaking would sound weird.
4.    Published SWF file size is 20.6 MB.
5.    I do have two externalized video files for title and end.
6.    Unfortunately, it is still slow even if it played on a different system.
And another problem comes up these days. After publication, the screen resolution is not good (like some grey ink left on screen) wherever click or type something. It did not happen before even if worked on the same computer.
I am very sorry that there are so many problems. I have been working on this for long time. The project totally drove me nuts. Hopefully you have more ideas about that.
I really appreciate your help.
Sincerely,
Linda

Audio several seconds out of sync with live video stream.

I did a live stream last week using 282,482,832,1500Kbps streams. What would cause the audio to get out of sync with the live video stream? I'm trying to determine if it was bandwidth related, cpu/memory issue on the FMIS 4.5 server, or an issue with encoding PC exceeding it's limits?
Thanks,
Dave

Which device are you using? Are audio and video coming from the same device or different devices?
Is it a USB device? Try changing the device and see if there is any difference. Changing bitrates will not affect audio-video sync.

Video out of sync with sound

Just got the latest update from Itunes 11.1.2.32 and now, when ever I play a movie in Itunes from the Itunes Store the sound is completely out of sync with the picture. All other movies players (DivX DVDs and Windows Media player) all play fine. Itunes played fine before the update as well. Any ideas?

Most of my video problems have come from using a computer too slow to play the file correctly. I cannot play iTunes video on my desktop have to use laptop.

My photos will not sync to my Apple TV (1st generation), ipad, iphone, or itouch. They used to be there but upon recent syncs with all devices they have all gone. I am totally baffled as I have not changed settings?

I had the same thing happen to me. It's a bug in iPhoto 9.4.2.
The first time you run iPhoto after upgrading to iPhoto 9.4.2, it "updates the iPhoto library". This sometimes tickles a bug where iTunes can see all your iPhoto albums, but iTunes thinks they are empty. Since iTunes thinks all your albums are empty, it dutifully deletes any photos from your synced iOS devices.
It's easy to tell if this is the problem you are seeing. Open iTunes and go to the photos sync panel for one of your iOS devices. If you have multiple albums checked, but iTunes shows a total of 0 photos, then you have the problem.
I spent an hour with an Apple Genius. he couldn't find any mention of this problem in their internal support system. His recomendation was to reinstall the operating the system. I suspect that this won't solve it.
The only solution I have found is to restore iPhoto 9.4.1 and the corresponding iPhoto library from your backups.
I would refrain from upgrading to iPhoto 9.4.2 until Apple has a fix for this issue.

Change of Video Frame One Sample Out of Sync with Correct Point on Timeline

Change of Video Frame One Sample Out of Sync with Correct Point on Timeline.
It has been found on the author's PC that, in Audition 3 in Multitrack View, a video file displayed in the video window will change its frame one sample later than it should do with respect to the correct point on the timeline. This has led to extra work having to be done by the author, as detailed later.
To demonstrate this issue:
Create a new multitrack session. Enable the Time and Video windows. Enable only 'Snap to Frames'.
Using an external program, render a two-frame video clip at 25fps. Let the first frame contain the letter 'A', and the second frame contain the letter 'B'. Making sure that the Display Time Format is set appropriately, in this case at 'SMPTE 25 fps (EBU)', lock this clip on the multitrack timeline, ensuring that the clip starts at time 00:00:00:00.
Create a mono audio clip of silence at 48kHz 32-bit that is two frames long. Lock it on an audio track, ensuring that the clip starts at time 00:00:00:00.
Place the cursor at time 00:00:00:01 and create a cue marker at this point by pressing F8.
Zoom into the timeline so that approximately twenty samples are visible, with the cursor lying on the cue marker in the middle of the screen. The Time window should display 00:00:00:01. The Video window should display the letter 'A'.
Move the cursor back in time (leftwards) by one sample. The Time window should change its display to 00:00:00:00, whilst the Video window should still show the letter 'A'.
Move the cursor forwards in time (rightwards) by one sample, so that it overlays the cue marker again. The Time window should change its display back to 00:00:00:01, whilst the Video window remains showing the letter 'A'.
Move the cursor forwards in time (rightwards) by one more sample. The Time window's display should remain at 00:00:00:01, but the Video window should now display the letter 'B'.
As can be seen from the above steps, the video's change of frame content occurs incorrectly one sample later than it should; the change of video frame content should occur simultaneously with the change of the frame number displayed in the Time window, which is at the point that the cue marker has been placed.
The practical effect of this issue is that it has caused the author a huge amount of extra work on an 89-minute long soundtrack-for-video timeline. There were over 1100 changes of shot which the author wished to mark by placing cue markers at the beginning of every shot. This should have been a quite simple process of enabling 'Snap to Frames', stepping through the video, and laying cue markers down by pressing F8 when the shot was seen to change.
Because currently the Video window (referencing the cursor laying over a cue marker
i that has been placed on the timeline using the 'Snap to Frames' option
) will actually display the end moments of the previous frame rather than the beginning moments of the current frame, laying down a cue marker when the shot is seen to change will actually place that marker at the beginning moments of the second frame of the new shot, not at the beginning moments of the first frame of the new shot, i.e. the cue marker placed will be one frame later in time than it should be. If it is wished for the cue marker to, as best it can, represent the beginning moments of the first frame of the new shot, it has to be manually repositioned so that it is at least a sample later in time than the time at which the shot has actually changed, in order for the Video window to correctly display the content.
The author had to manually reposition all 1100+ cue markers.
Ideally, the Video window should display a change of video frame in synchronization with the change of the frame display in the Time window, which occurs at the position of the 'Snap to Frames' point.
