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.

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.

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 after exporting sequence

I'm a FCP user since years, but not so common with HD footage. Therefore I have an issue with my finished edited movie after exporting: Video and Audio are out of sync.
My sequence settings are: HDV1080i50, 25fps, 48kHz, 16bit, Stereo. I used File-> Export-> Quicktime Movie -> Current Settings
Sequence has a duration of 61 minutes and 38 sec. I tried to find out where's the problem and exported audio and video seperated. This results in:
Video is 61 minutes and 27 sec long
Audio is 61 minutes and 38 sec long
That means exported video is shorter than original sequence.
What could that be ?

I had the same problem with a Panasonic camera, even filming at 30 fps. I was able to fix it; see [this thread|http://discussions.apple.com/thread.jspa?threadID=1783029&tstart=0]. It's a frustating problem, to be sure. You might have to use Easy Setup a couple times before you get things to work properly. Not sure why that's the case.
Good luck!

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?

Audio and video out of sync when using quicktime conversion

hello,
i am editing a hdv project and want to export to quicktime. the client needs it in a specific size (700x394). they do not want the video in the file compressed, just the size of image. they are compressing the video through flash for the web. anyways, i used to just use quicktime conversion, custom size and use 700x394, but now when i do that the audio and video are sparadically out of sync in the product. the wierd thing is that the project plays fine in the timeline, but when i export the problem occours. i then, exported to a full res fcp movie and it is fine. then tired reexporting through qt pro to 700x394. when i did this their were no sync issues but the quality of the file was not so good, it look more pixely, certainly not as good as when i did it using quicktime conversion.
how can i export through fcp to get the 700x394 file? someone said 'use current settings' instead of using quicktime conversion? how do i do this? what do i need to do and what are my settings?
any help is appreciated. thanks a ton in advance.
cheers,
clay

What format are you converting the HDV to?
If it's animation, it is quite possible your computer can't pull the data rate. In this case it would be a processor / hard drive issue not an out of sync issue.

Audio and Video out of sync in PPCS6.0.3

I imported a video clip into Adobe Premiere Pro CS 6.0.3.   I noticed that the video and audio are out of sync.   I played the video file through Windows Media Player and the audio/video are in sync.
However at 8min42sec, I noticed that the video becomes garbled but the audio track is fine.   The entire video clip is about 10min24sec.
I would like to trim the video file at the 8min42sec.   However everytime, I import it into Adobe Premiere, the audio and video are out of sync.   I wonder if Premiere is trying to stretch the video track to compensate.    Is there a way to import the video clip without having Adobe Premiere manipulating it.   Any suggestions are appreciated.

Audio and Video out of sync during editing. PLEASE HELP

I am using a MacBook Pro. Specs are:
- OS X version 10.9.2
- 2.5GHz Intel Core i5 Processor
- 4GB 1600MHz DDR3 RAM
When I import a video into AfterEffects CC, the audio and video are out of sync. The audio and video files are the right size, length etc. but are way out of sync. By the end of a 2 minute video, it can be out by up to 5-6 seconds. This applies to videos imported from any device. iPhone, USB and even videos I've recorded directly from my computer. Most files I try and import are MP4 files, but I've found the same issues with all other video files. I've even tried importing them separetely as an audio file and then as a video file. Nothing seems to work. I am also experienceing the same issue with Premiere CC.
Please help. I am needing these programs to work for assessment items.
- Andrew

Without knowing the specs of your videos it is hard to say. I'm also running a Mac and am having no such issues.
My first thought is that you have something from a 3rd party installed that is causing conflicts. If all else fails try transcoding your mp4 files to a frame based codec using the Adobe Media Encoder. Pick one of the Apple production codecs or Jpeg compressed QuickTime.
Are you running a ram preview? Did you render your Premiere timeline? Are you new to AE?

Audio and Video Out of Sync -AV sync problem

Edited a bunch of clips together from Canon T1i 720p, iPhone 3GS, Canon SX110, and Sony DSC-W70. About an hour long. Everything looks great when played within iMovie '11, but when exported, the audio and video get out of sync. It gets progressively worse the farther along you are in the sequence. AV is as much as 6 seconds off by the end!! Audio is ahead of the video. I've tried exporting in several different ways including: Export to iDVD, Export to Media Browser 720p, with the same results.
Anyone else having this problem? I know I've done this with success in the past with iMovie '09.

Im having the same issue I have a project that is 9 minutes long tried all before even looking at the forum but It will not sync. Some one even told me to repair the permissions so nothing worked. I went to the Mac store no body knew what I was talking about so they asked me to call Apple so I did and was hung up on 3 times not only that but I was advised since I just bought the product I did have 3 months of tech support.
I mean I'm having an issue and they tell me I have 90 days of free service? This has got to be a joke. I than asked well can I just take it back and instal my 09 back? I was advised nope you wont be able to do so and you cant get your money back.
After this whole mishap I did learned that the less snips and clips and editing is on the project the sync and video will be ok but if you have lots clips such as most of us than we will continue on having this issue.
We need a fix ASAP

Audio and video out of sync on converted AVI file

I am trying to convert a DVD to an AVI for playback on a device. When I import the DVD and publish it as an .AVI the output audio and video are out of sync. After about an hour of playback the audio lags the video by a full second. How can I correct this problem?

Walter0325
If you have Premiere Elements 12 on Windows 8 and you want to rip VOBs from the DVD-VIDEO to export subsequently to DV AVI, here are the details....
1. Do you have DVD-VIDEO standard or widescreen? Set the Premiere Elements 12 project preset manually.
File Menu/New/Project. Set the project preset to NTSC or PAL DV Standard or NTSC or PAL DV Widescreen depending on what you have.
Before you exit the new project dialog, make sure that you have a check mark next to Force Selected Project Setting on this Project.
2. In the Premiere Elements workspace, use Add Media/DVD camera or computer drive/Video Importer to get the VOBs (only the ones in the series VTS_01_1.VOB. Set to a folder in the Save In: location. Check mark next to Insert in Timeline. Hit Get Media.
3. If you have an orange line OVER the Timeline content, press the Enter key to get the best possible preview of what you have on that Timeline.
If after all that, the audio is out of sync, then use the Command Prompt method to get the individual VOBs into a single file with all the VOBs seamlessly merged. This worked nicely for a recent user here. See details in my blog post how to for the Command Prompt way.
http://www.atr935.blogspot.com/2013/09/pe-dvd-videoseamless-vob-ripping.html
Please do not hesitate to ask if you need clarification on anything that I have written.
Depending on your results, more information may be requested about the specific properties of what you have on that DVD disc.
Thank you.
