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!!

Issues with finder going out of sync with file images in cover flow.

Hi All,
I'm having issues with files going out of sync with images in cover flow since updating to Mavericks. Typically, if I had for example 10 pictures listed as 1 to 10, if i deleted images 6&7 the images remain in coverflow but the file listings are removed, then if i click on image 7 the file listing of image 8 is highlighted, then to make matters worse, if i click on the file listing for image 9 in shows image 8 in cover flow. To stop this I have to shut down finder and restart it, then the whole thing repeats itself if i delete more images. Its a nightmare when your working with 50 plus images at a time!!! Help!!
Thanks all.

com.apple.systemuiserver.plist and com.apple.finder.plist
Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J. When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder. Select Preferences/. Move the .plists to your desktop.
Re-launch Finder by loggin out/in and test. If it works okay, delete the plist from the desktop.
If the same, return the .plist to where you got it from, overwriting the newer ones.
Thanks to leonie for some information contained in this.
You might need to redo the View settings after an update.
If you look at the 'More Like This' box (top right) it seems the Cover Flow view is having problems.
Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.

Audio out of sync with video in timeline SOLVED

The audio and video are in sync when playing .MP4 video (but may apply to other video files) in the Premiere Pro viewer and Windows Media Player and VLC however, as soon as you drag the clip into the timeline it goes out of sync. Since it took so much time for me to figure out how to get around this problem I wanted to share this, ESPECIALLY For all the people who are semi Adobe Premiere noobs (with no disrespect, I fall into this category) at this and google isn't helping to figure out why this is happening I'll give you the easy fix. For all the people in this forum who are going to ask the detailed information, codecs, etc. I'll give that as well.
FOR THE NOOBS:
All the information I've read online all seems to point that the timeline sometimes doesn't like certain audio contained in the video. It conforms incorrectly, etc. Personally, it doesn't make any sense to me. Forget all that.. you just want to get on with your project.. to heck with the details, you're tired of googling. Here's the solution I found. Extracting the audio from the problematic video file outside of Adobe Premiere. I use avconv, because it's free, open source, and you won't lose audio quality. Then linking that audio with the video in Adobe Premiere.
First if you are using a windows 32 bit computer download avconv here: http://win32.libav.org/win32/
If you are using a windows 64 bit computer download avconv here: http://win32.libav.org/win64/
go to the bottom of the page and click on the newest date version. DISCLAIMER: This is open source software. It's free. I didn't make it so I'm not trying to sell you anything.
It's a zip file so you will need to use winzip or 7zip to uncompress it. You can't just click on the installer. You can uncompress and save the program wherever you want on your computer. Say you didn't pay attention and you automatically saved it in the default spot in your downloads folder. The place you'd find the program might look like this if you're on a 64 bit computer:
C:\Users\youruseraccountname\Downloads\libav-9.7-win64 If you're on a 32 bit computer it will probably look like this C:\Users\youruseraccountname\Downloads\libav-9.7-win32
Just make sure you know where it is located and copy it down in notepad. If you can't find it, do a search on your C: drive for avconv .For this forum thread we will assume you have saved avconv in the downloads folder and you're on a 64 bit computer.
Click on the Windows key on your keyboard. Type in Run and then press enter. Type in CMD and press enter. This will open up windows command line. Don't worry, it's not as scary as you think.
Now hold down the Windows key and press E. This will open up a windows explorer window for you to find the video file you are having issues with in Adobe Premiere. Once you have found the file, copy the location of the file. So.. if your file was here: c:\Users\youruseraccount\videos\yourvideo.mp4 you would see that at the top of the windows explorer in what's called the address bar. Copy that. Paste it into your notepad.
Now switch back to the windows command line window. Now I'm going to have you type a command into the windows command line but before you do I want you to understand how to type it in.
#1. Do you know the exact path (location on your computer) where you installed avconv?
#2. Did you copy the exact path (location on your computer) where you have your video file?
If so.. type in the command below but change it with the information you have above
C:\Users\youruseraccountname\Downloads\libav-9.7-win64\usr\bin\avconv.exe -i "c:\Users\youruseraccount\videos\yourvideo.mp4" -vn -qscale 1 "c:\Users\youruseraccount\videos\yourvideo.wav"
So let's break it down so you understand and help troubleshoot any issues you may have.
C:\Users\youruseraccountname\Downloads\libav-9.7-win64 this is the example location we said we installed avconv. The actual avconv.exe program is located inside that folder so the full path would be this: C:\Users\youruseraccountname\Downloads\libav-9.7-win64\usr\bin\avconv.exe
-i just tells avconv what the input file is.
"c:\Users\youruseraccount\videos\yourvideo.mp4" is the path (location on your computer) where your video file is.
-vn just tells avconv you only want to extract audio from the video
-qscale 1 just tells avconv you want the best quality
"c:\Users\youruseraccount\videos\yourvideo.wav" just tells avconv the path (location on your computer) and the name you want to give the audio file you're taking from the video. This will save the audio wav file to the path (location on your computer) where the problematic video file is saved.
Once you have the audio wav file import it into Adobe Premiere. In the timeline, unlink the audio from the mp4 (or whatever video file you have). Highlight the now unlinked mp4 audio and delete the audio. Then bring your audio wav file you created using avconv and bring it onto the timeline at the start of the video. Now link it. Hopefully that did the trick.
If you have any questions regarding the command line or installing avconv please feel free to comment and ask. I'm pretty good at windows command line and can probably help identify what the issue is.
FOR THE INFORMED PREMIERE PRO USERS:
Here are the details of the problematic video file that I had this issue with. This is from avconv:

I don't know the type make/model video camera that was used or if it was converted before being given to me. This is just what i had to work with and the solution I found to fix it.

if you are using a windows 32 bit computer
Then you won't be using anything above Premiere Pro CS4, and this thread would be in the wrong section.
By the way, the process is significantly easier using something like Xvid4PSP, which can strip out the audio using a fairly easy to understand GUI, as wel as convert those oddball videos into something PP can handle.

During editing on MacBook Pro 2.2GHz i7, audio goes out of sinc with video

I have been having a lot of trouble with audio going out of sinc after I have edited a 30 minute program. When I make a second cut, I find that the audio has jumped under the first cut about half an inch back, and this happens with every progressive cut. Then after "sharing" to dvd the audio is out of sinc with video throughout. I then have moved each one of these overlaps back into position and still have a problem with audio out of sinc.
HELP.

I was using a different laptop for post since the macbook was busy "sharing" to dvd, which, since I closely examined each cut at highest magnification to fix them ended up making video watchable. Not every cut came out of sinc, but several do.
It is both sides of the cut which come out of sinc, the right side laps over the left and then I noticed when I corrected them with greater magnification that the left side was moved left to cause a gap. I guess I just have to closely examine each cut when done with the whole video since also these overlaps are caused when I zoom out to view the whole length of the timeline, most of the cuts will overlap at that moment. Really strange. I had trouble fixing these but less trouble whe I turned off the snap in option.

My iTunes is playing the films with sound out of sync with video

I bought some films off of the iTunes store and whenever they're playing, the sound is out of sync with the video. Why is this?
Please help.
Sam.

Maybe this will help. My first movie I made in IMovie approached thirty minutes long. I read in a book that any movie made in IMovie that approaches that length or longer will start to lose sound sync. The trick is to extract the audio from the video. Sure enough it worked for me.

Audio locked at playhead, but goes out of sync if video is cropped

Hi,
Using iMovie HD 6, I have the audio locked at playhead, but if I crop part of the video (beginning or ending), the audio goes out of sync.
Here's what I've done:
1) Extracted audio from video
2) Silenced this audio
3) Imported audio from audio recorder (Edirol R-09HR)
4) Synced the imported audio
*5) Attempted to crop part of the video footage in the timeline... goes out of sync
How do I keep the audio in sync when cropping video?
Thanks!

Hi JohnDoe2009 - firstly, extracting the audio is not necessary in your case. Simply mute the video's audio, by reducing its level to zero - that is what actually happens when you extract the audio, after all.
It is my experience also, that locking audio clips to particular video clips is not fail-safe if further cropping is done afterwards, especially if that cropping is fairly substantial. Where possible, do the syncing after all crop-editing has been completed.
As a last check I always review the syncing before finalising the movie.

Audio slowly drifts out of sync with video

I have a long continuous video clip (.MP4) that has an audio sample rate of 48 kHz. Separately, I have an audio clip (.mp3) for that take that was recorded at 44.1 kHz.
I created a sequence in Premiere with the .MP4 making sure the sequence's audio sample rate was set to 48. I brought the .mp3 into Audition where I used Edit > Convert Sample Type to change it to 48 kHz.
Back in Premiere, I dragged the converted .mp3 into the sequence and the audio still drifted out of sync toward the end of the clip.
Am I missing a step? How can I make sure the audio and video are in sync throughout rather than just in the beginning?

Two independent record devices will not stay perfectly synchronous over a long period of time unless locked via timecode or a sync cable.
A solution is to scroll to the end of the clips and adjust the speed of the mp3 file (making it run slightly faster or slower) until the end of the camera audio and mp3 audio coincide.

Live multitrack recordings drift out-of-sync with video

This is the second time in two years that I've encountered this intermittent problem, and I can't figure out what causes it or how to solve it. I made a video recording of a musical group and simultaneously made an 8 channel multitrack recording of the same performance using Audition and a MOTU 8pre. When I try to combine the mixdown from Audition with the video file in Premiere, the audio from the two sources starts to drift out of sync after about two minutes. This doesn't seem like it should be possible, as both are digital sources. Has anyone else ever encountered this? What is the cause? Is there a solution?
What makes this more mysterious is that I've also used the same technique on previous occasions without experiencing this problem.

"You say that there is a fix for the division problem. If you don't mind, could you tell me what that might be? "
The reason 48k was chosen as THE sample rate for broadcast video is that there is a straight easy (integer) relationship between frame & sample rates for all used frame rates bar 29.9700299700.......... [yup it's an infinite unresolvable number] where though not simple it was still a lot easier to resolve if not perfectly but to a tolerable/usable level the arithmetic problems. Good news is this happens automatically in the editing software so long as enter the true known info IE 48k for audio 29.97 drop frame for Video. Conversely it won't {probably} if you choose 44.1.
Getting 29.97 in sync is complex however and may involve using .1% "pull-up's & down's Basically the Color frame rate in the States is .1% less than the B&W rate of 30fps. If video is actually at 29.97 but counted as though 30fps there will be a little over 2 sec error per hr.
tell me what was the diffeence in length you got per hr min or whatever?
One solution of many is to use an actual sample rate of .1% greater than 48k IE 48048k & it gets even more complex if using timecode
Word clock
It's a 5volt square wave, carried on a BNC cable, used solely for audio syncing. No video equipment understands word clock.
Pro video equipment can use video sync aka Black & Burst - a feed of which also using a BNC cable can link / tie the clocks of a number of cameras and also some audio equipment so they are absolutely in sync (unfortunately for you not the Motu 8pre which as far as I can see has no external sync possibilities)
Your "workround"
yes of course regardless of what is causing the problem, a time stretch / compression of the appropriate amount can make the pic & sound the same length and so joy.

Sound out of sync with video

When i watch the video on my ipod the sound doesn’t match up with the mouths of the characters, I used quicktime pro and adjusted it to sync well with the video, in quicktime the sound and video match up perfectly but as soon as I put it on the ipod then its out of sync.

Anybody have any suggestions? Or is there a different way to adjust the sound with video?

Teouble with audio becoming out of synce with video.

Hello, I'm using final cut to edit my videos but for some reason, FCP has been giving me some issues. In my work flow I often layout two long video track in the timeline, then I will chop up the top track to create transitions from the top to the bottom and vise versa. as soon I press play, it the video will start off in a slower speed almost as if the computer is overloaded, then it catches up to normal speed in about a second. This has really been driving my crazy. It also effects the way video syncronizes with audio. I can lay both video tracks on top of one another perfectly in sync with the audio, but as sometime once it get's to new scene or the video switches to another track the audio is no longer in sync with the video. sometimes I can stop the footage, then press space bar to copntine and the audio and video will be in sync. This is really weird and I was wondering if anyone has any answers for me. I'm pretty sure it's not an overload on the system because the projects are rather small, and I'm using a quad core 2.5, with 5 gig of ram. and this is my graphic card info

Thanks so much for you time.

Yes. Those that are designed to work with A/V files will work better.
Drives from G-tech and Granite Digital are worth a very close look.
However, if you have an empty drive bay in your G5, a second internal SATA drive is the better choice.
good luck.

Video is going out of sync

So I don't recall any upgrade before this issue began. Upon opening an old fcp project file a few of the tapes appear to have gone slightly out of sync. This is not a gradual sync issue that frequently results from audio rate mismatching. It's like the whole tape is five to ten seconds off from the source audio captured at the same time. The strange thing is that when I render out the video it appears in sync. Also when I use the slip tool the reference frames in the viewer window shows the correct frames as far as I can tell.
What's even more strange is that footage I just captured for a new project seems to be doing the same thing and it only happens on some tapes. Other tapes work fine. Another way around this issue that I've found is to nest the sequence. When nested the correct video plays. It's really weird.
It's been a nightmare to edit. I constantly have to flip back and forth between sequences and the exact edit is always a guess and check process requiring rendering frequently just to see if the cut is correct.
I am and have always been editing 24p advanced footage. None of my settings have changed. This issue popped up out of nowhere.

If you are running FCP 4.5 and OSX 10.4.9, >>THIS THREAD<<</a> may be of interest.

Clip audio is out of sync with video

After analyzing the clip the code tells the tale. The audio is "shorter by 1 1/2 seconds yet the time line doesn't reflect it. I want to fix the problem but the tool I found requires the clip (red rectangular box with the +/- info.) to option/click on to be given the re-sync tool action. Other solutions require complicated solutions. My question is "What happened to cause this sync problem and how can I avoid it in the future. ie: no evidence of =/- red boxes to show that there is a problem even thought it clear when you look at the video clip ?

We are missing fundamental information:
What codec does your source footage use?
What is the audio sampling rate on the source footage?
What are the Sequence settings in FCP and does what you see there differ in any way to the properties of the source footage?
Version of Mac OS X, FCP and QuickTime?
Also; if you have a 2 x 3 GHz Dual-Core Intel Xeon Mac OS X 10.6.6, it's a Mac Pro, not a G5.

My MPEG video/audio goes out of sync

Hi
I am importing some MPEG- 2 video clips into Premiere Pro. They are totally in sync before I import them but once in Prmeiere the video and audio are no longer in sync. The format is MPEG-2 video, 1920 x 1080,25fps, 48000hz.
Can anyone suggest anything?
Thanks
Miranda

Hi there
Thanks very much, I donwloaded the MediaInfo software.
So the clips came from a Sony NXCam using a Black Magic stem and VMix to record with.
The files are MPEG2 1920 x 1080 as you can see in the screenshot.
The file info in Premiere says they are pixel aspect ratio 1.0
As for codec information, where can I find this?
Regards

The solution:
Always use 16-bit/48kHz audio.

It's all down to Percy, that is perseverance, I do not like to give up.
Under Sequence in the Menu bar I clicked on Sequence Settings. There under Render there is a Render Control tab. I changed the codec from 'Same as Sequence Codec' to 'Apple ProRes 422 [HDV, XDCAM HD/EX/HD422 only]' and everything is back to normal, even the pixelating text (see an earlier post of mine). The rendering is quick as well. The world is my oyster.
