Sound and video out of sync????

Ok...... My purchased videos, film or music, during playback are out of sync. They start ok but the picture jumps and then plays out of sync and this becomes progressively worse. I have removed all apple software and reloaded and this has worked in the past but it will not cooperate now.
This is driving me mad. What's worse is if I use quick time then there is no problem at all but as soon as I launch a film in iTunes ......aaaarrrrgggghhhhh!
It may or may not be related but whilst playing music with full screen visualiser I get a random unexpected computer shut down for no apparent reason.
Please, somebody help before I launch the laptop window-wise.

My standard list of things to do first for these wierd sort of problems, but I also tend to run these before I go to burn an iDVD project just to be safe. Keep in mind this list represents the programs I tend to use. There are several alternate programs that do the same things with some combining the functions of some of the ones below. So everyone has their favorites, but here are mine...
Run MacJanitor (free download) to do all the Unix Cron Maintenance scripts.
Run Disk Utility (Applications -> Utilities) and repair disk permissions on your start up drive (typically your internal drive). Also verify any other drives mounted on the system, especially any external drives that you use for iMovie and iDVD projects.
Run Preferential Treatment (free download) to check for corrupt/damaged application and system preference files.
Run Cache Out X (free download) to clear all system and application caches.
Reboot your Mac (after running Cache Out X you are given the option to restart the machine).
If you still can not get it to run correctly, next thing to try is to throw out the iMovie preference file (don't forget to change back those preferences you want different from the defaults next time you run it). If it still doesn't work, then I would suggest you reinstall iMovie.

Audio And Video out of sync in Final Cut, but not in quicktime

I heave searched the forums to no end to find the solution to this issue, unfortunatley, I have not solved the problem.
I am using Final Cut 4.5 on a G4 running OSX 10.3.4. This system has worked perfectly for years with no problems. Neither the system, hardware, or software has ever been changed on this machine. Suddenly last week, despite perfect sync while previewing the capture, the Audio and Video were of sync in Final Cut, but when checked in quicktime, there were no problems. That is how I eventually figured out this was a final cut problem.
By out of sync, I don't mean it is by a specific number of frames that can be adjusted and then everything is fine, the sync seems to drift so that if you edit the audio to be in sync in one part of the video, it won't be at the end. Also, it is out of sync from the first frame played, not a gradual drift.
This is definitely not an issue of frame rates or final cut settings as will be evident by the steps I took below to find the source of this problem.
This is what I did to attempt to fix the problem:
- Check drives using disc utility and repair permissions
- Remove Final Cut Preferences using Apple guidelines
- Switch hard drives
- Delete Final Cut and reinstall newer version of final cut (since the capture files played fine on Final Cut 5.1 on another machine)
- reinstall entire OSX 10.3.9, wiping the hard drive and reinstalling Final Cut 5.1
- switch ram slots, and even replace ram with different sticks from another G4 machine
None of these solutions worked. Is there some hardware problem with my G4 that is suddenly causing Final Cut to play audio and video out of sync?
Hope you can help, otherwise this otherwise great G4 is going in the dumpster!
Thanks

For what it's worth, I'm having what looks to be the same problem. Driving me insane. Here's what's going on-
Editing in FCP 6.0.2
QT was just updated to 7.3.1 the other day (hmm)
On an MacBookPro machine, OS 10.5.1
Software updater says everything's up to date of course.
DV-NTSC 24p (23.98) Advanced Pulldown Removal (footage was shot at 24PA on a DVX100b)
In Quicktime, the file previews fine, everything's in sync, everyone's happy. In FCP, the video and audio are wildly out of sync. I did a test inside of quicktime and sliced out a small portion of the media clip and did a "save as" and this small slice played in sync in FCP. However, this did not work for the entire clip. Clip is weighing in at 5.58GB for a 32 minute run.
I'm trying to multicam 2 tapes together and manually syncing these up is proving to be difficult at best. When anyone gets any ideas/leads/patches, let us know.
Grr,

Audio and video out of sync on short recordings

I've scanned the discussions and see that alot of posters are experiencing
the same problem I'm having which is recording quicktime movies
and getting audio and video out of sync.
In most of those posts the responses seem to be that the problem gets
bad if you're making a long recording. I'm experiencing that, but...
...I'm also having the same problem on really short recordings...less than a
minute. I've coming video and audio out of my cable box, into a SONY DSR-11 VCR, then firewire out of the deck into the computer, recording the movies with Quicktime 7.1.6.
I know it's coming out of the cable box and then out of the SONY deck via firewire in sync because when I log and capture through Final Cut Pro, audio and video are in sync in preview and playback. I don't want to use Final Cut Pro to capture the movies because I want to end up with MPEG4, and I'd have to go through an extra conversion process out of FCP.
Any thoughts on why even short recordings through Quicktime are out of sync?
Thanks.

I'm having similar problems transferring VHS video to Quicktime. Another problem I'm having is when I transfer a VHS video to iMovie and then export the video to H.264 format, I have similar sync problems, even though the iMovie seems perfectly in sync.
I'm going to try to transfer several alternative video formats (video from my cable DVR, Video from live TV, and video from a digital mini cassette to try and figure out whether the VHS format is the culprit. Will keep you posted.

VOICE AND VIDEO OUT OF SYNC

HEY, i made a huge imovie project.. and the sound and video is out of sync, the sound comes seconds before the video... HELPP!

I must say I am still astonished how much this is a problem in general. I saw Seinfeld on TV once with the lips still moving for about a second after the voice stopped. I'm talking about cable TV, here! And there are the videos on You Tube. A lot of them are out of sync too.
Synchronizing sound and picture was initially a difficult problem, but the movie industry pretty much solved this c. 1930. And now, EIGHT DECADES LATER, suddenly it's a big problem again.
Yes, for this and other reasons, the world will end in 2012. (^_^)

Compressor audio and video out of sync

I've edited DV video in FCPX (where audio and video are in sync), sent to Compressor, and added the Dolby and MPEG-2 settings to my submitted job. But when I add the output files to Toast, the audio and video are not in sync. Reviewing the video in Compressor, it appears they are out of sync there as well (though it's hard to tell due to the choppiness of the playback there).
Any idea why this is occurring?

Try filling each gap in the audio timeline AND / OR set your encoding to CBR (Constant Bit Rate), not VBR. In some cases the DECODING part tries to fill gaps by "pulling" the next part of the audio if the stream has been encoded with VBR. Good luck.

Audio and video out of sync on capture

I have been using the Canon HV20 and MacBook Pro for about a year now with no problems and for the first time today on capture the audio and video are out of sync. I have been using an external LaCie for capture and stoage but even using the internal HD, the same problem is occurring. I checked my preferences in FCE and used the disc utility to make sure my HD had no permission problems. I am not dropping any frames on capture. What do I do next to correct?

Hi - Thanks for you response.
It's a Canon XH A1 which is an HDV camera. As far as output is concerned when I play the camera it says HDV 24 and the sound is 16KB.

Sound and Video not in sync

Dear Forum,
apologies if I happen to ask something already treated elsewhere (I searched and didn't find)!
I'm having the following problem with my 3rd gen Nano: in movies longer than around 20-25 min sound and image progressively get out of sync. The sound runs ahead of the picture - after around 45 min the shift can be several seconds. The video is encoded with EyeTV (the "iPod best" setting) in H.264 at 640x480, 25fps, around 1.6 Mbps. This should - according to the nano specs - be fine.
Has anyone else come across this?
Does anyone know of a fix?
Thanks very much!!

same issue here.
no fix

DVCPRO HD timecode - audio and video out of sync

I'm hoping this will turn out to be a "d'oh!" moment, but...
I'm working on a project which is being shot on the HVX200, with audio captured separately. The video is transferred to me via a FireStore, and I import both the video and separate audio (which is recorded to four .wav files) using the 'Import' command. Both video and audio are captured using free run timecode.
When imported, the video and audio have wildly different timecodes. For example, the video clip whose timecode starts 08:47:39:02 has a matching audio clip starting at 13:39:36:09. What's more, several of the video clips have the same timecode, even though they're different clips!
I've been through my settings and can find nothing obvious that I've done wrong. It's possible that the DoP and sound recordist have incorrectly synched their timecodes, but unlikely. Can anyone please think of anything that I could be doing differently which would solve the synching problem, or do I have to go back to the other guys and tell them the problem's probably with them?

Sounds like something that has to be done on set, then.
The audio's not being captured by the HVX200, perhaps I didn't make that clear; it's going to a separate hard drive. However, the HVX200 IS recording some audio using the on-board mic for reference, which is the only way I have any chance of synching the audio and video.
While in conversation with the DoP I notice that the filename for each video clip does contain what appears to be a date and time. This makes it possible to match each video clip with the relevant audio clip. However, this still makes it hard for me to do a frame-perfect sync as the timecodes are still radically different.
Anyway, the DoP who owns the FireStore is going to go away and look at it, so I'll let you know what he comes up with.

Audio Tracks and Video Out of Sync!!

I am having a problem with not only the video and audio being out of sync, but the audio tracks, left and right, are out of sync with each other. I know it isn't the camera or tape because I watch the footage while it's capturing and it is fine, plus it happens all the time, with different tapes and different cameras. What would cause this and how do I fix it? Also, how do I set my preferences to automatically start the camera when I click capture? I have it set on my iMac but I can't find it on my G5.

Itunes does not play video properly - sound or video out of sync

About 6 months ago, all of a sudden my itunes for windows starts to play my movies or tv shows improperly. Video is frozen while the sound plays. Or the exact reverse happens. Apple showed me to uninstall fully and reinstall Itunes, which worked once. Couple of months later the same happens again. I tried again a proper uninstall and reinstall but to no avail.
I have been using Itunes for windows for the last 4 years and nothing ever went wrong like this. Now the only way to see my video is to sync to my iphone.
Anyone have this problem? I've read about the codex issues that can cause problems. I tried some of the fixes and nothing works.
Even says that the firewall or virus programs can interfere - I'm surprised if that would be a cause.
I have a recent laptop with windows 7 premium, 64bit. When I bought it about 1.5 years ago I had no problem with Itunes.
Thanks,
JR

You synced the sd version to the ipods?
You can report the issue to itunes. They should resolve within a day.

Beyond that, I am not sure what the issue would be.

Audio and video out of sync

I have captured tapes from my DVD camera and am in the process of editing clips and have noticed that the video and the audio are slightly out of sync.
How can I correct this?

I don't think it was a "DVD" camera!
Often sync problems are caused by recording the audio at a different setting than the Easy Setup capture preset.
The normal DV-PAL or NTSC Easy Setup is for 16bit audio.
If you recorded at 12 bit you need the "DV-PAL (or NTSC) 32KHz" Easy Setup.

Audio and Video out of Sync in Encore 2.0

Here's my issue:
I opened a project in Encore 2.0 that was an Encore 1.5 project. I have one timeline with a 2 hour movie and the AC3 audio file that goes with it. Encore 1.5 played the audio and video in sync from the timeline and burned discs with the audio in sync. The video is an MPEG2 file encoded at a 3.1 constant bit rate.
In Encore 2.0, when I play the timeline, the audio becomes progressively out of sync as it plays. Within the first few minutes it's maybe a frame or 2 off. By the end of the film it is about 18 seconds off (audio is playing ahead of the video).
Is this a result of Encore 2.0 conforming the audio file? If so, how am I (or anyone) supposed to attain sync between video and audio in Encore 2.0?
I have Encore 1.5 and 2.0 both installed on the same machine. As a test, I opened the project in 1.5 and played it, everything was fine. I closed Encore 1.5 and opened the project in Encore 2.0, and the audio is out of sync.
Any comments, ideas or suggestions?
Mike

Joe,
I tried creating a project with the original WAV file and it's corresponding video and found that the audio and video were still out of sync. I did a little more testing and discovered that the audio is actually being played correctly, it's the video that is not being played correctly. Here's what I did:
I opened the WAV file version of the audio file in Premiere Pro and noted where a hammer hit in the video occurs (01;40;30;28). I then opened Encore 2.0 and imported the video and AC3 version of the WAV file, placed them in a timeline and the audio's hammer hit is right where it's supposed to be (01;40;30;28), but the video's hammer hit occurs at 01;40;43;18.
Next I went into Encore 1.5 and brought in the AC3 audio and video files and placed them on a timeline. I went to 01;40;30;28 in the timeline and the audio and video were both at the frame they should be at that timecode.
Seeing how the video appears to be playing incorrectly, here's some info on my video files:
I have 4 versions of the same film in varying encode rates with the same start and end timecodes. All four files were encoded on a Sonic DVD Creator authoring station using hardware to encode. The files are encoded at the following rates: 2.9 constant bit rate, 3.1 constant bit rate, 3.4 variable bit rate and 4.0 variable bit rate. They are each NTSC with drop frame timecode. All four files play correctly in Encore 1.5 but incorrectly in Encore 2.0.
This almost seems like a drop frame/non-drop frame issue. Do you have any ideas?
Mike

In all your information, I did not see what computer operating system your Premiere Elements 12 is running on? Have you updated 12 to the 12.1 Update, using an opened project's Help Menu/Update? If not, please do so.
Your issue may relate to the details of your "VOB file" and how it was ripped/copied from the DVD-VIDEO and DVD disc to get it into a Premiere Elements project.
a. project preset set for NTSC DV Standard or NTSC DV Widescreen (whichever corresponded to your recording details)...or PAL equivalent.
b. DVD disc in burner tray
c. Add Media/DVD camera or computer drive/Video Importer/.....
It does not happened often, but if audio is out of sync and you are not using the above route, then consider the Command Prompt way described in the
following
ATR Premiere Elements Troubleshooting: PE: DVD-VIDEO/Seamless VOB Ripping
A just in case note, contrary to some, it is not necessary to convert VOB (VTS_01_1.VOB video file and any files in that series) to any other format in Premiere Elements.
Please review and consider and then we can decide what next.
Thank you.

Audio and Video out of Sync after Pro Res export

I´m getting an audio/video sync issue when I´m exporting to Pro Res.
I started off in a HDV1080i50 sequence. Audio sampling rate is 48khz. (16 bit depth)
The sequence is less than 20 minutes long. It plays correctly on the timeline.
When I export the sequence for DVD and view it on a set top it plays absolutely fine.
When I export the video to ProRes (422 HQ - I used Export using Quicktime Conversion) and the audio to AIFF, they quickly go out of sync. This was brought to my attention first by the guys who were making the DigiBeta master, and when I view the exported material in a Pro Res sequence I can see it for myself.
The audio and video clips are of the exact same duration.
Possible issues...
Some of the narration was recorded at 44.1 khz. I didn´t resample it (I´m still a learning novice..).. but if that is the issue should it not have affected the DVD as well? All the other audio in the project is 48khz.
Most of the material is HDV1080i50..but one clip used was originally an NTSC clip and therefore a different frame rate. However I converted it to a 25fps clip and this is reflected in the vid rate column in the browser where it says 25fps.
Final point, the exported AIFF files..when I import them back into the HDV1080i50 sequence and play back, it is perfectly in sync.
Any help would be greatly appreciated.

First, yes resample the narration to 48k 16 bit. You will probably be able to reconnect to the resampled files. Usually works for me. That's a simple fix and will probably solve the problem. If it doesn't, you can try to change the codec (compressor) in the sequence settings to prores 422HQ, fully render and see if that solves the problem.
Wait, just reread your original post. Export from fcp using file: export: quicktime movie NOT quicktime conversion with current settings. If that works without synch issues, use compressor to convert to prores.

Audio and video out of sync after import

I'm trying to bring some H.264 video into a Premiere project. But when I place it in a sequence (a sequence that is created based upon this very clip), the audio and video are about a second out of sync. (It's also odd: no amount of adjustment will bring them in sync. Seemingly the video is running at some variable rate that makes synchronization impossible...?)
As a test, I tried bringing my video into iMovie, and it works just fine there. But I don't want to use iMovie: I want to use Premiere.
Any ideas?
