Audio Sync problem after exporting

App : Imovie
Device : Ipad 2
iOS : 4.3.3
Rushes : MP4 from a FLIP camera
Audio track : m4a
The project is around 9 minutes. Sync ok in Imovie. After exporting, the sync is ok in the beginning but loosing it more and more as the movie goes.......i tried all the options on exporting, nothing changes. This is getting me mad......Any solutions ?

I am assuming this is because the way the flip camera embeds the audio.
The problem with editing non-iframe video is that it does not have all seperate frames.
And so the audio is sync in blocks to video.
I assume that the reason iMovie iOS is stated as only supporting video shot on an iOS device is that this video has a "standard" way to sync audio.
There are many different ways to encode mp4s.
Editing a non-Apple iOS standard video may give you these problems.
So the only real solution I can give is to convert all your video to the same standard as the iPad shoots.
You should tell Apple here, and ask for a fix:
http://www.apple.com/feedback/imovie_iOS.html
And also email other editing app creators and ask them to port to the iPad.
Then you will have more options to edit then just iMovie iOS.

  • Audio sync problems after export

    I've been having this problem occasionally ever since starting to use Premiere Pro CS6, and it's now also happening again in the latest version of CC (just updated to 7.2.2 on W7, 64bit):
    A perfectly synced sequence that plays fine in its rendered preview loses sync with its audio (or the audio with the video) after exporting to mp4. (preset H.264 format). I have tried trouble shooting by deleting all render files, restarted application and computer, played with different media players... to no avail.
    Admittedly the raw footage happens to be a wmv file. Which I know is not ideal. But what bugs me is that everything is perfectly in sync up to the point of creating the export file. That makes no sense. I'm about to counteract this shift now by separating the audio from the video and making up the frame difference manually, but it feels wrong to do that and is a silly hack to something the software shouldn't mess up in the first place.
    Any ideas?

    Holy cow, that was easy. You were right, that worked. Doooh.
    Thanks.

  • Major "BUG" in Imovie 9 - Audio Sync Problem on Export  !

    Well I'm a hard-core Apple user from day one, but unfortunately today I'm not to proud about the latest version of Imovie 9.
    It seems there has been a "MAJOR audio sync problem on export" in Imovie 9, since July 2009. Apple knows about this bug for a long time now, but didn't release any bugfix yet!
    Here's what it's all about:
    It seems if you use the (custom /manual) speed-adjustments and not the preset slider speeds, you will experience (after exporting your movie) annoying bursts of audio from clips that had been set to mude. The strange thing is that you will only experience this audio-bug after exporting, you will NOT experience it in the project playback mode!
    Here's what you can do:
    Find ALL the clips in your Project that are Speed Adjusted.
    Instead of using a "Custom Speed" percentage, use any of the "Preset Speeds"
    Preset Speeds on the Slider = 12.5%, 25%, 50%, 100%, 200%, 400%, 800%
    Then, export your project as usual.
    No more sync issues.
    Really hope That Apple will come up with a real BUGFIX soon.
    It's a shame that a major bug in a otherwise GREAT PRODUCT, hasen't been fixed yet!
    What's wrong with Apple?...this is not one of their finest hours.
    Still A BIG fan from Imovie HD,...I'll chance to Imovie 9 when the bugs are finaly fixed!

    This is TERRIBLE! I have spent so much time working on this project, and I really don't want to adjust the speed settings to the preset levels, BECAUSE I need to motion of the video to match certain musical points. I can't re-film my video, and I needed this project done TODAY. I made a music video with some kids at summer camp, and today is the last day- the day we were supposed to all watch it together, and now, I've got NOTHING!!!! (Because I can't export it without all those glitches!)
    I am MAJORLY DISAPPOINTED on this one. I've made movies in windows movie maker before, and purposely used imovie, because you know, everything on macs is supposed to be better. Well, I guess I was wrong.

  • Audio sync problem after scrubbing

    I'm trying to piece together some clips from a TV series called Legend of the Seeker. I'm using Premiere CS4 4.0.1, Vista Ultimate 64-bit.
    Placing the hour-long video in the Source Editor allows me to play the video fine from beginning to end, but if I start scrubbing through the file, the audio unsyncs itself immediately.
    Here's a screenshot of the video in GSpot:
    http://img14.imageshack.us/my.php?image=premieresync.jpg
    Setting IN and OUT points and then dragging a very small clip into the timeline has the same result.
    Any ideas would be very appreciated.

    You are actually pretty lucky to just have Audio sync problems, though I do not know why scrubbing would make any difference. With both Xvid and DivX one more often gets no Audio, or no Video.
    Agree 100% on the 3rd party conversion, prior to Import into PrPro.

  • Audio Sync Problem after transitions/filters applied to timeline in FCP

    I have Final Cut Pro 5.1.2 on a MAC Pro. I installed 2 Maxtor SATA II 200gig drives and created a striped RAID. I want to be clear about audio sync issues. I have my easy setup/properties....all those settings set to DV NTSC and I am monitoring out from my DV Deck via firewire, not the audio from the computer.
    After capturing the clip(s) I assemble them onto the timeline, add a few transitions or filters. The audio shifts off a lot. More everytime I add or do more with the clip. After rendering more, the audio shifts more. All scratch disks, rendered clips points to the Video Drive (striped RAID) I've setup. I'm not new to video editing but new to a MAC. Yes, I am a PC guy. I work with Premiere Pro 1.5. I am pleased so far making the switch, just need to fix this audio issue.
    All properties of the audio clip are correct, DV NTSC properties - 48K etc. This particular capture I made with 2 channel mono clips instead of a single DV stereo stream, simply because I have a split audio on the production tape and would like to take advantage of working with two seperate mono audio files. When I trim, I make sure the audio stays with the video but it appears that when I do trim, add a transition or filter, that's when the audio goes out of sync. No indication with a ("- #")on the icon. The clips which I captured are less than a minute long. Used for testing in these new learning stages.
    Questions:
    1. I created a striped RAID with the 2 Maxtor drives, I used MAC OS Extended (Journaled) with 256k Raid Block size. Is this correct?
    2. Would the audio captured in 2 channel mono affect the sync? (assuming you don't shift it manually on the timeline)
    3. What other MAC settings should I do to the system that will result in better preformances?
    4. What settings should I set in FCP for better performance results?
    MAC Pro   Mac OS X (10.4.8)   FCP Studio
    MAC Pro   Mac OS X (10.4.8)   FCP Studio
    MAC Pro   Mac OS X (10.4.8)   FCP Studio

    hi vcp
    welcome to the forum, glad you made the switch ... you won't be sorry (although you might be wondering at the moment!)
    1. nothing wring with that
    2. no
    3. just don't install 3rd party crap you don't need ... and don't install any anti-vrus software
    4. no special settings required
    what camera did you capture from? did you capture with FCP?
    cheers

  • IDVD audio sync problems after Lion upgrade

    Hi all,
    I posted this in the Lion discussion, but thought I might have a go here as well. I'm having problems with iDVD and audio sync as follows...
    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, I find it very unacceptable - 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 ? I never had this problem at all with Snow Leopard.
    Fox

    I've discovered that the problem appears to be the conversion of the mpeg file to the DV file. The video/audio goes slightly out of sync using MPEG Streamclip under Mac OS Lion. I never had any problem with Snow Leopard. I'll have to try different conversion methods and see what happens...

  • Premiere Elements 8: Audio sync problem when exporting to Quicktime H.264

    Program plays back fine on the timeline also when saved as a mpeg file. QT file audio sync is off. Using QT player to play back. Any thoughts?

  • Weird audio out of sync problem after export

    This is the second time I've run into this problem. My video and audio are in sync in my timeline, but upon export to QT, one of the clips (but ONLY one of the clips) is out of sync. I tried exporting two different times: same result.
    Doesn't make sense to me. All the clips were imported from the same DV tape from my Canon HV30.
    Can anyone give me some advice here?? Thanks.

    How are you exporting? The first quicktime export option or quicktime conversion? What are your settings for the export?
    Did you capture with device control with abort capture on dropped frames and create new clip on timecode break enabled?

  • Audio sync problem after saving to QuickTime file

    Hi there, I'm relatively new to Adobe Premiere - I'm not quite knowledgeable enough about video editing to really use it to its full potential but needed something more flexible than Windows Movie Maker.  I haven't had any problems before editing smaller files, but am having tons of trouble with a 2.7 gig file.
    I'm trying to take a 2.7GB .MOV file recorded on a Kodak Zi6 and divide it into three roughly equal parts to use an email sharing service that has a maximum file size of 1GB (I know that there are sites that will allow 3GB files and I wish I could use them, or use an FTP server, but the person who needs the video needs it to be sent over his own company's file sharing system).  It was recorded on an 8GB SD card, that SD card was put into my computer, and I then transfered it over to Premiere Elements 8.
    I rendered the entire file first (it wouldn't even play until I did that) and after rendering, the audio and video were good and everything was synced up.  I then split the clip into three and saved each as a separate project.  Then I opened one up again and tried to save as a Quicktime file (that's what the person I'm sending it to requested).  All seemed to go well, and for the first minute or so of the 15 minute clip everything is great.  Then after that, the audio gets more and more out of sync as the video plays on.  I tried playing it on several different players, same thing.
    My computer (a Cyberpower PC) is running an Intel Core i7 CPU, 870 @ 2.93GHz 3.06 GHz; 8 GB of RAM; NVIDIA GeForce GTX 285; Windows 7 Home Premium.  I'm not sure where to get the rest of the information requested in the "How to best ask for help" post but if you can give me some guidance I'll find it.
    The presets are on the defaults because I wasn't aware of them until I came to this forum.  Happy to try the whole process again if someone can tell me what the presets should be changed to.
    I'm looking for a solution to this particular problem, but am also looking for some basic help about files.  The files that I used most often usually come from a Kodak Zi6 (.MOV) or a Flip Mino HD (MPEG4 I think; had to convert those to something else to use them in Premiere at all).  I have AVS Video Converter 6, so I can convert those files to pretty much anything.  I'm wondering what I should convert files to before trying to edit them in Premiere, and how best to save them.  I rarely use the files anywhere but online if that helps (this particular 2.7GB file being a big exception) at a maximum width of 550 pixels, so I don't think I need the quality to be all that great; it's more important to me to be able to work a bit quicker, without rendering that takes hours.
    I'd also love to take advantage someday of some of the more advanced features of Premiere, so I was wondering if anyone knows of any tutorials that will walk me through things in a linear way (as in, start from the beginning and teach me what I need to learn before moving on to something more complicated).
    Thanks so much for your help, and please speak slowly; I'm in over my head!

    Very well-done post, and welcome to the forum.
    First, many have issues with OOS (Out Of Sync) with QT files on Export/Share. This is not just with PrE, but PrPro also. Unfortunately, OOS is pretty easy to fix, when you encounter it on the Timeline, but almost impossible to fix when it creeps in during Export. As an aside, I fought some MPEG Audio from a client, that was perfect in the Timeline, but when Exported to MPEG-2 for DVD-Video, ALWAYS went OOS dynamically, and even adjusting for that on the Timeline (rather guessing how much OOS the other direction I needed,) just flat would not do it. Sync would be fine for awhile, and then suddenly start going out, before miraculously returning to sync with the next Clip. Never could get that one correct.
    In your MOV Export/Share, I am not certain which CODEC you chose. Was it H.264?
    Within the MOV "wrapper," did your recipient give you any options for the enclosed CODEC's, or is the wrapper and the file size the determining factors?
    Wish that I had more to offer directly, rather than questions.
    As for the tutorials, I strongly recommend Steve Grisetti's Learning Series, his Boot Camp and his many articles and general PrE tutorials on Muvipix. He also has several books, available there too.
    Good luck,
    Hunt

  • Audio dissolve problems after export

    Hello there.
    I have a problem with audio dissolves. If I export the mastermixed file, the is strange and the mixing isn't right. Where I put a audio dissolve in fading in or out the music sometimes is doubled.
    In Premiere, everything sounds fine. When I export in ProRes I get these audio problems. Before the update to 8.1 everything went well.
    Any ideas?
    Best regards,
    Florian.

    premiere CC 2014.1

    I got it. It's the AME export! If I export the file directly with Premiere I have no strange audio probs but if I export the soundfiles or the program file with Media Encoder 2014.1 the dissolves are really bad...

  • Audio sync problem when exporting between FCP6 and Soundtrack

    Hi, I'm a newbie to this so apologies for any glaring errors.
    I've recently upgraded to FC studio 2 and have exported the audio of an existing 20 minute custom format quicktime project (720x408, 30fps,) to soundtrack for sweetening.
    Trouble is, when returning the audio back to FCP, the audio is shorter by several seconds and therefor totally out of sync! I've also tried outputting the multitrack audio from within FCP and bringing it back in as a single file and this is also out by several seconds. The output settings are the same as the project.
    If I do nothing to the audio and simply send it to compressor; the M2v and it's aiff play in sync in Quicktime.
    Any ideas or work arounds?
    Thanks in advance for any advice.

  • TS1363 Audio Sync problem - Audio is late, after a scene people are talking and audio does not relates

    All the TV shows purchased and downloaded have AUDIO SYNC problem.  This does not happens with any other video I watch from other sites, i.e. ABC, NBC, Showtime, all which I watch with no audio problem.
    The audio is always late, people are talking and scenes change and the audio belongs to the past!  Please help me to solve this!

  • CS4 audio sync problems

    Hi all,
    sorry if this question is old hat - I've searched the forums and can't seem to get a clear answer (most refer to CS3 and before) so thought I'd ask anew.
    My preview in Premiere CS4 is fine, as is the preview in Encore CS4. The video was captured from four tapes (HD as mpeg and SD as Matrox AVI) in Premiere. The final DVD (10 minutes) consists of 21 clips. All but one are OK - this one has the voices well out of sync with the video, even though other clips taken from the same tape are fine.
    I also had a major problem recently with an MP4 from youtube, which I guess is the same issue - everything else was fine, but this one clip was well out.
    I'm guessing by now this is an old problem. What's the solution, please?
    Thanks
    Paul.

    Newbie to Adobe here ...
    Okay,  so after spending over 14 hours trying to fix the audio sync problem I fixed mine. After editing my project I selected Sequence > Sequence Settings > Playback Settings > under Realtime Playback make sure the "Desktop Video Display During Playback" box is selected. Next, in "External Device" change the setting from "None" to your next option. Mine reads DV: 29.97 720 X 480i. Next, Under "Export" section in that same window select the in "External Device" select the DV option again. Also, you might want to "Disable video output when in background" ...select that box at the bottom of the screen.
    Now, try recording the video to the tape ....my audio now sync's as normal. I hope it works for you.\
    One more thing ... you can keep the "Desktop Audio" button selected.

  • Audio sync prob after capturing for 10 minutes or so

    I have an audio sync problem when I import into Final Cut Express. Everything is fine but lets say around 15 minutes or so there is a slight sync problem.
    What I have been doing is I import into IMovie because I have it setup to cut the clips after 10 minutes. This is great because I can let it run..and it automatically splits the clips up without any dropped frames at all. The problem is I then have to drag those clips..one by one into my external harddrive. That takes time and then I have to render the audio in Final Cut Express.
    I do like though that the clips are a little over 2gigs..which is good for transfering between drives and backing it up onto a DVD.
    Is there a way you can do what I do in iMovie...it automatically starts a new clip after ten minutes or whatever...this way I don't have to transfer and render.

    FCE does not break up clips on capture. You can capture in 10 minute chunks if you want.
    The audio sync problem can be caused by a number of things most common of which is using the wrong settings for your capture, where your settings audio sample rate doesn't match your media.

  • Audio Sync Problems With Share YouTube -- OSX not iOS

    I've replicated this several times. It's maddening and bizarre. *Share YouTube*
    Exporting a FCPX video using the "SHARE" menu and choosing YouTube causes the resulting upload to be out of sync when viewed in Safari or other browsers on iOS
    Viewing the same video on the iPad with the built in YouTube app, the video plays in sync
    Viewing the same video on AppleTV 2 (with the 5.1 update), the video plays in sync.
    If I export using Export Media menu item under the SHARE menu, and then from QuickTime Player choose Export For Web (under the File menu) and manually upload, the video is in sync.
    Note, that using
    Feel free to try on this short simple and silly video http://www.youtube.com/watch?v=cGTQNMJdPRQ&list=UUiDxioBFJCPC-8OUFifsx8A&index=2 &feature=plcp
    Anyone else experience this. Is this a bug or a feature? Rather not go through three steps to upload a simple YouTube video.

    We've got the same problem and yep, it's infuriating that are so few posts about it.
    It doesn't happen with every video, but the vast majority of files that we've tried to either export directly to YouTube from QTX or export locally and then manually upload to YouTube end up with shockingly bad audio sync (and also some colour issues, but that's another story).
    As a small video production company we were chuffed to bits with the improved export speed in QTX and quick to make use of it. But when we realised there was a problem, we had to revert back to using QT7's painfully slow export.
    We've run experiments on a brand new iMac and MacBook Pro running the most up-to-date version of OS X and still no joy. Always the same audio sync problems with the same video files.
    In the meantime however,  we've found that the settings advised on this YouTube help page have given us the best (albeit slow) results at both 25fps and 30fps when exporting from QT7:
