DVD audio slightly out of sync

Whenever I watch a movie on the DVD player on my macbook, the audio seems slightly out of sync. This happens with any movie I play so I know it isn't the DVD that is the issue. It is like the audio of a characters voice plays a fraction of a second after it should. Has anyone else experienced this or am I just crazy? Is there a quick fix for this problem?

First of all, when you export, you should see the dialog box that has information about the source video as well as the export. If you are shooting 25fps then you are not in the USA. If you are in the USA, look harder at your export settings.
But that isn't the problem you are facing.
Are you using the Vimeo app to play the videos on the iPad or are you just playing it in a browser? Use the app if you aren't now doing so.
I doubt that you are using anything other than AAC for your audio from what you have said about using the presets, but I have to ask. You are using AAC, right? That is what Vimeo prefers.
Have you tried turning the HD off in Vimeo to see if that clears up the problem? That will probably be fine on a smartphone. An iPad might see the difference though.
You are not going to be happy reading this Vimeo.com thread, but here it is anyway.
I don't even know what to make of this one.
In any case, you will read for yourself that you may want to change browsers on the mobile device.

  • When exporting separate audio and video streams, the audio drifts out of sync

    So this is my first slightly larger project in Final Cut Pro X.
    When I export my finished project (around 12 minutes long) straight to quicktime, it plays back perfectly.
    When I export using compressor, the resulting audio and video streams are two different lengths. The audio comes out a full second longer. If you try to lay them down in a program like Adobe Encore, the audio starts out perfectly in sync. Two minutes in you notice the video is slightly out of sync with the audio. By the end of the video it's comically bad, over a second out of sync.
    What's even more vexing is if I try to take the quicktime file that IS in sync upon playback, and try to convert it burn that to a dvd or blu-ray using toast, the problem re-emerges.
    I triec searching around, but most of the suggestions that came up were vauge, like, "Upgrade to a real program like Final Cut." (This was in reply to people who were using free software programs.)
    I did see one idea surface where 44 and 48 kHz sampling rates don't play well together. So I combed through my project and found all the 44.1 songs that were used, and swapped them out with upsampled versions. Nothing changed. It didn't sound like it would fix it, as people usually said it was a specific amount of frames off, not something drifting out of sync.
    So the question is, does anyone have any suggestions on what could be causing this? Thanks! :-)

    Project settings can be accessed and changed by selecting the project and pressing command-J. Then, in the inspector, click on the little gear in the lower-right hand corner to access the settings.
    Why are you trying to output video/audio separately? If the content plays in-sync when exporting a quicktime movie (using current project settings), you could try separating the video/audio using MPEG Streamclip as a second step instead of using compressor. For audio, don't change the sample rate from the project settings, and use uncompressed audio (AIFF) as the output format.

  • Exporting keynote to iDVD audio is out of sync with presentation

    I am working in Keynotes '09 I have a presentation that is time perfectly when I run the slide show. I have a totally different problem when sending it to iDVD or to Quicktime the recorded audio is out of timing with the presentation. I tried everything but nothing seems to be working, Tech Support can't seem to help me out. The problem is not within Keynotes as far as I can tell. It plays fine in Keynotes. It is happening in the export via QuickTime or to iDVD. Does anybody have a clue as to how I can resolve this issue. Audio is checked when syncing there is sound in iDVD it is completely out of sync with the bullets point and overlapping spoken text from sentence to the next. I used an AAc Encoder on the spoken text synced into itune placed spoken text in to keynotes. should I have used MP3 encoding? that is the only thing I have not tried.

    Hi Steve,
    I'm having a similar, if not exactly the same problem. I often download files from my Beyonwiz PVR, convert them to mpeg and DV files using MPEG Streamclip (with Quicktime MPEG playback component), then burn a disc with iDVD. Since upgrading to Lion, I notice that the audio in these files, and the burnt DVD in particular, can be slightly out-of-sync with the video. Although the effect is slight, it's completely unacceptable in my book - its like trying to watch something that been badly dubbed. I find it to be a very jarring effect to watch voices and intonation out of sync with the picture.
    I'm not sure where the problem lies - is it Quicktime, MPEG Streamclip, and/or iDVD ?

  • AirTunes to Apple TV is slightly out of sync with other AirTunes devices

    I've noticed that AirTunes playback through Apple TV is slightly out of sync with the audio output from my Macbook and the AirTunes via my two Airport Express Base Stations. The audio from Apple TV is about a second delayed, causing a mismatch between AirTunes playback on the TV and my Macbook and other AirTunes devices. Thus, my Macbook and AEBSs are in harmony, but Apple TV's AirTunes is about a half-a-beat delayed.
    Has anyone else noticed this problem or know of a way to remedy it?

    This is quite intriguing. I would expect that an amplifier would be able to decode the digital signal with no noticeable delay, otherwise DVDs etc would play with audio out of sync when using the digital output of the player. In fact, rather the opposite is true with new larger screens where it is the video that's slow and the audio needs to be delayed.
    So this would point to the Apple TV's digital output being delayed vs. it's analogue output and I'm not too sure I understand why. It receives digital information over the network and then takes longer converting that to SPDIF (its digital output format) than it does converting it to analogue. Odd.
    Perhaps an expert can advise us on this.
    This would however explain why the Airport Express can exhibit the same problem and why some people don't experience any delay - they are probably using the analogue output of their Apple device.
    What we need in iTunes when selecting devices to play from is an additional control for each with a +- setting that can adjust the delay of each output device so they can all be brought in sync. Since the delay appears to remain consistent that ought to solve the problem for everyone once and for all.
    I'll try some tests of my own and see if my problem is indeed this digital delay.

  • Audio goes out of sync when i open project on diff macs

    i have an iMovie project created on an iMac saved to an external.
    I go to open the project up on my macbook and the audio is out of sync.
    I go back to my iMac with the same project and it works just fine.
    I'm a bit confused because both macs use Mac OS X 10.6.4 and iMovie 8.0.6
    what other differences might there be?
    any input is appreciated as I'd love to work on projects while out in the field!

    Try exporting the iMovie project as a single full quality dv format quicktime file.
    I use iMovie6 HD and this is my usual procedure that works well.
    Make the movie in iMovie, will involve many separate clips. When finished, export (share) as a single full quality dv format quick time file. When I have an hours worth of smaller projects, I create a new iMovie project and import all of the quicktime .dv files for each separate short project. I add chapter markers in this project, then share with iDVD. I then burn an hours worth of stuff at best quality and distribute to family and friends.
    iDVD seems to work better with iMovie source that has fewer clips.
    BTW: Are you having problems with standard def or hi def iMovie source. Another part of my procedure is that I take the raw tapes and download the entire thing into one iMovie project. I don't edit or change the footage at all, just want to archive to DVD for posterity. In this case, I want to share the iMovie project with iDVD directly. This has worked OK for standard def projects, but my first hi def project (1080i) that I tried, the sound was out of sync. To fix this, I had to create a regular DV widescreen iMovie project, and drag all the clips into it from the HD project. It took over an hour for my humble mac mini to convert the files, but I was then able to share with iDVD and the finished DVD worked ok.
    Hope this helps.

  • Why does my audio slip out of sync when exporting?

    I am exporting an HD edited video. I shot 1280x720 & editing in FCP 6.0.5. I am using APPLE PRO RES 422 1280x720 30fps 48kz . Should it be (HQ)?? - I do not select re-compress all frames or make self-contained. I just want a QT reference file to view and then burn a DVD. My clip is 43 minutes long. HOWEVER, the audio drifts out of sync BIG TIME. Why is that??
    Here are my sequence settings:
    1280x720 Aspect Ratio HDTV 720p (16:9)
    Square Pixels
    H.264
    Audio at 48kHz

    That's what I thought, however, when I play back the .mov file after exporting using "current settings", that's when I experience OUT OF SYNC audio. Do I ignore that and drag and drop that file into iDVD and let iDVD crunch it??? Is it just the playback of that .mov file that is out of sync?

  • Final Export of a Project Slightly Out Of Sync

    Hi there,
    I'm trying to find an answer to what seems to be a common issue when exporting projects out of Final Cut Pro X, however I haven't yet found any answers that work or that tell me things I don't already know (don't mean to sound know-it-all though).
    The issue is that after I have exported my project, the audio and video are out of sync. It doesn't drift as the video goes on; it's out of sync by the same amount from start to end. Of course, when editing and viewing the project in Final Cut, the sync is fine.
    The project was created from scratch with the Apple ProRes 422 setting, the two original camera angles were both 25p, the audio I'm using is 48K/24bit which the project is setup as also. The audio was originally recorded at 48k/24bit and mixed seperately in Pro Tools and was exported as a wave file (48K/24bit) and brought back into Final Cut.
    I can't think of what else to describe. All the project settings and the original footage and audio setting are exactly matched. There's no frame rate changes, no audio resolution changes, no MP3 in the mix, no apparent issue when viewing/editiing in the project, and I even tried optimising the video and exporting just to see if that made any difference.
    I usually listen to the audio via an RME souncard which is setup to be low latency. However, whether I view the project and then export via the external audio interface, or view the project and export via the laptop speakers (with not extrernal audio interface connected) it's the same result: slightly out of sync video!
    If anyone has any ideas I would be most grateful.
    Cheers,
    Chris

    Hey Russ,
    Thanks for your time. When I say a 'common issue' I found that when I searched it both on Google as well as this support forum I found multiple threads and questions pertaining to this issue of sync and/or drift.
    I tested this single angle idea by using the footage in a nother project and exporting part of that (without changing angles) and it seemed to be OK. However I have other projects which are only single angle but they export slightly out of sync as well. I haven't found a common denominator yet.
    When I say out of sync, it's not dramatic, however it's always the same - the audio is just a few frames behind the video. This has happened with most of my projects using different footage and different audio, etc. No matter what setting audio and video are recorded at, and regardless of whether I dramaticallty colourise or add effects to the video or not, it's always the same result; slightly behind audio when exported.
    With regard to presets, do you meet export settings? If so, I'm mostly exporting using H.264 and as a Quicktime Move (AAC) output. I've tried various resolution changes and tinkering but nothing has changed.
    If you're referring to project setup presets, I can't really change too many things because obviously the audio resolution and video frame rates are predetermined so I can't try 25p footage in a 30p project, etc.
    Thanks again,
    Chris

  • When I use media manager to upres clip audio goes out of sync

    I captured a clip and put it in DVNTSC 48kHz timeline at OfflineRT NTSC (Photo JPEG) then used the media manager to create a new sequence at full DV NTSC 48kHz res. I choose "Create offline", "set sequences to DV NTSC 48 kHz", and check all the boxes. I save a new project, open the new timeline and recapture the clip. The video looks great--it recaptures in full DVNTSC 48kHz res. But the audio is out of sync (by about 28 frames it looks like). What am I doing wrong? (This is the first time I'm trying this offline-then-online-process.) thanks.

  • Exporting to HD - audio is out of sync

    Hi
    (I'm using Elements 4 and Vista.)
    I've completed my video and all looks great on preview and in timeline - however, when I export to the HD (whether it's windows media or mpeg etc) the audio is out of sync? It seems to be in slightly different places too...
    (I have rendered etc).
    Any ideas?
    Many thanks
    Z

    It's most likely related to your source video. This is especially common with video captured by a program other than Premiere Elements.
    What type of video files are you using as your source -- what kind of camcorder did they come from and how did you get them into your computer?

  • When I trim a Video in QTpro, the video and audio become out of sync

    I use mpstreamclip to export video to mov or mp4 files. When I load up on QT pro and then do some trimming, the resultant clips often have audio and video that are slightly out of sync.
    Can anyone provide some guidance on what to do?
    Thanks so much.
    Skip

    I think it is going to be a problem with the fps setting on export. If you entered 30 fps as the setting for export and you found the result had the audio getting further and further ahead of the video the longer you watched it may be that you needed to enter a frame rate of 29.97 fps to keep things in sync. I am doing similar tests on some conversions because I have had sync problems as well. I will repost when I check my current export at 29.97 fps.

  • Music slightly out of sync when exporting in Premiere CS6, format problem?

    Hi guys, i have a quick question.
    I edited together a promo for a local band and everything is perfect in the sequence as far as being on point with the music at certain beats and such. However when I export it the music is slightly out of sync, which is bad when you edited everything specificly to the song. I am not using ANY audio from the footage but instead layed a music track over everything. I'm not sure what else to do, could it be a format problem? I am using h.264 (see below), but would AVI or anything else work better? any help is appreciated thank you!
    I am exporting directly from inside Premiere CS6 using a custom H.264 preset. 24fps, VBR 2 pass encoding. Target 7MB, Max 11MB. (with render at maxium bit depth, and render at highest quaility selected.)
    I put the audio settings to high, 320kbs AAC format.
    I use a custom built PC with an i7-3770K, 32 GB RAM, and I exported to a 120GB SSD.
    Any other info you need just ask.any types for uploading to vimeo so it doesn't get out of sync there? thank you in advance!
    Also, any types for uploading to vimeo so it doesn't get out of sync there? thank you in advance!

    Hi,
    I dont think that you will really get a problem while exporting in any of the given formats. But i would really like to check if the audio layer is exactly same as of the video. for eg - if my audio is 00:05:30 and my video is 00:05:20 , we might face issue with the sync.
    We can try to put more black video to make it a match with the audio and then try to export.
    Where do you have the media files , on a internal drive like c: or desktop? In case not , try to move the media files to desktop and then try to export.
    Also instead of exporting the files to your 120GB SSD , try to export it on the desktop.
    Hope it helps.
    Thanks

  • Rate Stretch audio goes out of sync when exported.

    Audio, which is rate stretched using the rate stretch tool to 100.01%, plays fine in Premiere Pro CS6. However, when exported to Encore or to MPEG-2 file, the audio is no longer stretched and becomes out of sync by the end of the video. When I play the preview in Encore, the audio is out of sync. Switch back to Premiere, it is OK. Export a MPEG-2 file and author a DVD, the audio is out of sync. Go back to Premiere, it is OK. I record the audio using a TASCAM portable recorder. I have recorded and synched audio many times and this is the first time that it does not work, on two separate Premiere projects. Any ideas on how to fix this. Even better, is there a way to record audio so that it matches the video (from a Panasonic HD AVCHD camcorder) without requiring rate stretch adjustment?

    Try changing the speed with right click, Speed/Duration instead of using the Rate Stretch tool.

  • Video and audio goes out of sync when imported into Premiere

    I have some videos ripped from some DVD that an acquaintance made, with an open source program called HandBrake, with the default "high profile" settings. When I play it both in VLC and in Quicktime, it plays just fine, but when I import it either in Premiere or in After effects, the video and audio goes out of sync (the video ran faster than the audio and when the video stops, the missing audio is trimmed).
    Video info according to Premiere (in Spanish but you may get the meaning).

    "HandBrake, these days, is almost entirely about H.264 video, aka MPEG-4 Part 10.  HandBrake is migrating to quality-based encoding."
    Hmmm.  I use HC Encoder to make my DVDs because it's the only free encoder I've found with the much more professional Constant Q encoding option.  But HC Encoder doesn't do HD sources for Blu-ray, so I've been wondering if I'd be stuck with the lame-*** consumer CBR and VBR options most encoders provide (including Adobe - hint, hint) when I eventually start working in HD.  This is a very interesting program, Handbrake.  I will have to check it out.

  • Audio Drifts Out of Sync After Demux

    Hi,
    I demuxed an hour-long program from DVD to .m2v and .ac3 using MPEG Streamclip. The audio drifts out of sync very gradually, and by the end is way off.
    I don't want to re-compress the audio, as it is already AC3. According to Quicktime, the video is 29.97 fps, and the audio is 16-bit 48 khz.
    When I used to Export to DV option, everything stayed in sync. I can't go this route, however, since I can't afford to re-compress anything (I'm making a new DVD from this old one). Just an FYI that this worked.
    Ever run into this problem before?

    I am using version 1.9. In the preferences pane, I don't have anything checked.
    To reiterate, all I'm trying to is demux the DVD as-is and bring those assets into DVD Studio Pro for an updated project. Not using FCP anywhere in this workflow.
    Looks like I left out an important piece of info, though...When I demux the audio stream to AC3 (its original format), and try to import it into DVD Studio Pro, I get the error message: "Variable bit rate audio assets cannot be imported." I am not sure how the client originally encoded their audio, but the fact that it stays in sync on the DVD led me to believe they didn't do anything wrong. Could this VBR be throwing the audio off during the demux? The only instances where I've noticed it's out of sync are when I export to an uncompressed format like AIFF or WAV, and can actually view it.

  • Audio plays out of sync initially on burned disc

    Now that the project is built, I'm having a strange issue with audio sync on my test DVDs. In some set-top DVD players, the audio starts ahead of the video in each segment; but then the video catches up to the audio after about 10 seconds or so and stays in sync for the duration of that video clip. This issue does not occur in computer DVD players. Given that these DVDs are comprised of math lessons with lots of starting and stopping, the sync issue is a persistent annoyance. The audio is out of sync at the beginning of each lesson since the user has to manually start each lesson from a menu. Why would this be happening and does anyone have an idea of how to make it go away?
    The video was compressed in Apple Compressor 2 at 3 Mbps with audio at 192 Kbps Dolby. Each lesson is a discreet MPEG2 and AC3 file and graphic slates intervene between each video clip or lesson (not my idea). The graphics (slates) are rendered in DVDSP. The video lags behind the audio each time one of these slates is passed even when the user selects to view a series of lessons without interruption.
    Hope any of you can help.
    Richard

    I am having the same issue. Just burned an hour long documentary and it seems to be out of sync. Not on all players, just a few. Also it appears that if the track is started over, to the beginning it seems to be in perfect sync.
    I am doing some research on this today. If I find anything I will let you know.
    I did find one thing already at
