Slow loss of audio sync during playback

When watching video podcasts. I nptice that the audio slowing falls out of sync with the video. I am running quicktime that comes with iTunes 10.1. Any ideas?
Regards
Phil

I nave updated Quicktime which did not work and then iTunes with Quicktime and I still get the out of sync problem.
One other issue is that when a video or video podcast ends iTunes freezez and appears in task manager as "No Responding".

  • Exported Final Cut XML from Imovie09 causes loss of Audio Sync

    I have recently upgraded to ILife09 and tried a process that always worked in ILife08 but now get Audio Sync problems.
    I have created an Imovie project that is 2hours and 50 mins long and wanted to export it to Final Cut Express as XML. This used to work 100% with Imovie08. However, with this latest version of Imovie, when exported to Final Cut Express, the first 45 mins of the XML movie is well out of sync (Audio / Visual).
    Has anyone experienced this?

    Hi Roberic,
    there is a bug in iMovie '09 that causes loss of audio sync when you use custom slow/fast motion. This has been experienced by many users. See for example this thread:
    http://discussions.apple.com/thread.jspa?messageID=9152271
    I don't know if this applies to exports to .xml but it could well be that your problem lies here. There are some workarounds, being the easiest one to only use what the slow motion slider snaps to instead of entering custom speed percentages.

  • Loss of audio sync when importing Samsung Galaxy 2 (GT-I1900) video to Premier Elements 10

    I am loosing audio sync when I import video from a Samsung Galaxy 2 GT-I1900 phone even when using settings chosen by Premier Elements 10. 
    The file plays OK in Windows 7 media player.
    I have tried using both direct import from the phone and transferring the file separately without solving the problem.
    The Premier Elements is version 10.0(20110902.Mol11.B123.280463)
    Unlinking the audio and video makes no difference.
    VideoReDo reports the file as :

    Letting VideoReDo simply rewrite the file resulted in loss of all but the first few seconds of audio. 
    Elements seems to have imported the file as NTSC-AVCHD-AVCHD LITE 720p 30fps
    The computer is running Windows 7 Professional  64 bit version  Service Pack 1 kernel 6.1.7601.17944 (reported by SIW)
    The computer motherboard is a Gigabyte Z68x-UD3H-B3 with an Intel Core i5-2500 CPU at 3.30GHz. Memory is 4GB.
    I note that others have had similar problems with non video recorder recordings.
    Can you suggest any file conversion of the original that will work – I have tried several with no improvement in the final result.
    And can anyone shed light on what is the basic cause of these problems?

    According to the Adobe installation information the trial version of Premiere Elements 11 is fully functional and the watermark is only present until a licence code is purchased.
    I have edited AVI footage from a camcorder using the program with no problems (and no loss of audio sync) and the watermark is also present with this.
    The odd placement of audio and video was caused by my not dragging the clip carefully enough.
    What is odd is that the clip plays completely normally using WIndows Media Player and VLC Media player so I would expect Premiere Elements to be able to handle it without problems.
    I think that there is some sort of bug in Premiere Elements' handling of mpe4 files (both in versions 10 and 11) rather than there being anything wrong with my computer.
    Is there some way of communicating this directly to the Adobe programers ?
    I enclose screenshots of the project settings:

  • Audio falling out of sync during playback of videos

    I now have Windows 8 on a brand new laptop, and new TV dls fall out of sync between audio and video within minutes.  Skipping to the beginning and dragging back to my last place in the timeline corrects this for a minute or so, and then falls out of sync again. 
    Also, other new purchases skip/pause every few minutes.  I tested previous dls (that are still in the cloud) and had no playback problems.  I don't want to delete everything and redownload until I know for sure that is the solution.

  • Loss of audio sync

    I use FC Pro 5.0.4 with the video card Digital Voodoo D1 64 RT (driver 7.5) and with the sound card AES-32 of RME, because in the past I've had problems with the audio section of Voodoo (many pops and clicks). Both are connected to a Leitch SPG-1601, one to BB out and the other to word clock out. The capture is OK but when I edit to tape I have a random loss of sync of 2 or 3 frames, the audio comes first than video. When I edit to tape FC PRO show me this warning:
    The selected audio and video devices may not match:
    - Digital Voodoo.....
    - Hammerfall DSP AES-32
    Please verify that the audio and video outputs are externally routed to the intended device(s). Do you want to proceed?
    The settings on the RME for me are correct and also on the Voodoo.
    I don't know what to do. Please help me.
    Power Mac G5   Mac OS X (10.4.5)   2 x 2 Ghz, 3 GB RAM, Quicktime 7.0.4

    It appears it occurs when you use an external monitor. If you turn the monitor off it syncs up.

  • Audio sync during print to tape

    I have been trying to print a sequence to tape. The audio drifts gradually during the 37 min clip. It plays fine in FC but not once on tape. Audio settings are all 48k, time code is all drop frame. I exported the file to a self-contained Quicktime and reimported that to a sequence and then printed but it still drifted by then end. The footage is DVcam 60i, nothing too taxing. Im printing to DVcam. Im using a Dual Intel MacPro with Final Cut 6 and OSX 5.3. Im out of ideas, does this problem sound familiar to anyone?

    I did finally get it to work. Here is what I did. Instead of making the sequence a self-contained Final Cut movie, which I thought would have worked (but didn't) I exported to Quicktime Conversion, choose the same compression (DV), then put the Quicktime file into a new project and Printed to Video. The audio stayed in sync for the whole 37 minutes. It is not a solution but a work around. I would still like to hear if anyone has a theory about this, or even a similar experience.

  • Audio Stutter during playback, ONLY in Soundtrack Pro

    Just today when I opened an aiff file exported from a Final Cut project, I noticed that playing back this file in Soundtrack produced a stutter for almost every second, like a metronome. Scrubbing the playhead along the audio waveform would give me about a 1/2 second of audio but then go silent until I let go of the mouse button and grabbed the arrow again to scrub.
    The more effects I put into the project, the worse the stutter becomes, but still in the same time (like I said before, like a metronome). It just becomes more pronounced. If I export from soundtrack, the audio is fine. Playing the AIFF file before and after in quicktime, the audio sounds fine.
    I've since tried different file types, from MOV to MP3 and each file has the same outcome, so it's definitely something wrong with Soundtrack.
    I've tried trashing the preferences, but that didn't help either. I've never run into this problem before and couldn't find any related issues in a google search. If anyone has ever experienced this before, please help. I've used this computer for over a year with no problems and it was used for a couple years before I started using it, also with no problems.

    Woo Hoo!!!
    Thanks, Tim for the post. I have a G5 Quad 2.5 GHz and I got the same STP stuttering when I upgraded to Leopard. Playback was stuttery. If I exported to AIFF, the output file played back smooth, which was fine until I tried to export a non-aiff file. AAC and MP3 files ALL have the same stuttery audio as the STP source - I discovered this yesterday creating my first podcast.
    So, now if becomes an issues. Searching for "Stutter" found your post. Reading the kenstone article cleared things up. Since I import audio from MiniDisc via optical, I already had a cable attached to the input. So, I attached the other end to the output and... like magic, perfect playback.
    Heavy sigh of relief!!
    Thank you immensely!!

  • Loss of Audio and Video Playback

    Hello.
    I am currently using Adobe CS6 Production Premium on Windows 7 Ultimate. I have updated alll of my sound card drivers.
    While in Premiere Pro, if I unplug my headphones, so that I can hear through my speakers, the video and audio playback hangs. In order for both playbacks to work again, I must restart the program. The program itself does not freeze, as I am able to drag clips as well as save the project.
    Any help would be appreciated.
    Thank You.

  • Toggle Two Audio Tracks During Playback?

    Is it possible to post a QuickTime movie to the Web with alternate soundtracks-- so the viewer chooses to view the video with either soundtrack #1 or soundtrack #-- but still sees the same (and only) video? I'm trying to save server space b/c this project will involve a number of videos and each will be posted in high and low bandwidth versions.
    Read only if you're curious as to why I want to do this -- the reason for this is to provide #1 the standard audio track for the movie and #2 the alternate track that contains both the standard audio track and audio description. Audio description provides oral descriptions of the visual information during gaps in the dialogue/narration of the main program. Folks who are sighed would choose #1 and folks who are blind or have low vision would choose #2.
    Thanks for sharing your wisdom.

    There are some more complicated ways to solve the problem, but a very easy way would be to make two reference movies, and have both audio tracks as external movies. Your reference movie 1 would have the video only movie and sound 1 only movie inside it. The reference movie 2 would have the same external video only movie, and the second audio only movie.
    I was worried that there might be something strange about the progressive download, like would all of the first track have to download before the second one started to download, so I tested it:
    http://staff.funnygarbage.com/colin/3tracks/g1.mov
    http://staff.funnygarbage.com/colin/3tracks/g2.mov
    http://staff.funnygarbage.com/colin/3tracks/g3.mov
    http://staff.funnygarbage.com/colin/3tracks/one.mov
    http://staff.funnygarbage.com/colin/3tracks/two.mov
    http://staff.funnygarbage.com/colin/3tracks/three.mov
    Don't try the first three links at first, just the second three links. You should find that any of the three starts to play as soon as it can, while still downloading. The first three links are the actual external files, and the second three links are tiny reference movies.
    The one thing your users would give up would be the ability to change tracks in mid play (that can be done in other ways though), but for your application hopefully someone won't decide half way through that in fact they are poor sighted, and should have used the other link.
    One other possible advantage of the reference movie approach is that the track that is currently not being heard does not have to be streamed, which would eat into the bandwidth.

  • Video doesn't play while audio does during playback

    I use FCE 1.0.1 and since I upgraded to Leopard I have had a little problem. When I put the video setting in Fire-Wire, it plays fine with audio playing through my camcorder. But when I put the video setting in Real Time to play the audio through my speakers, the video doesn't play while the audio is playing fine. After 5 or 6 seconds, the audio stops playing too.
    My G5 is a single 1.8 GHz processor and I am running 10.5.1
    Anything?

    I appreciate your insight with this. If I could ask one more set of questions; Would you recommend the "upgrade" linked below or the Full version? And what will be the practical differences for me the user?
    I have started a new project in version 1.0.1 (capturing and a few edits, etc) since upgrading to Leopard. Will all of my work be there with either upgrade or full version after install?
    Thanks so much.

  • Audio Dropout During Playback

    As I'm playing clips, whether on the timeline, or in the preview window, the audio will cut out for intervals of about 2 seconds then come back, then off again.
    This has happened to me on two different systems with two different projects. One you could say is slightly under powered (2.8 Ghz P4 with 2 GB of RAM, GForce 6600GT) but the other is a workhorse machine (Two Dual Core Xeon 3.0 Ghz processors. 4 GB RAM, GForce 8800). Both machines are running XP. The lesser system is my personal machine running Premiere Pro 2.0, while the workhorse is my work computer running CS3. Both are having the same issues.
    Some details about the event:
    1. This only happens when I'm working with HDV footage.
    2. This only happens when playing files that do not have to be rendered. Like playing clips back in the Source window, or on the timeline where there are no effects applied (there is no red bar above it.)
    To remedy this for some projects I have put a blank title on the top track of the entire project. I think that this forces it to play it back in a way that it's not raw and has to do some small amount of processing on it. It still plays back fairly smoothly, but not like when it's raw and working correctly.
    3. If I just put focus on another application for a second then come back it will play fine for about a minute before it starts cutting out again.
    Any ideas or suggestions as this is incredibly annoying. The only thing that I thought it might have something to do with is that they both have Cineform isntalled (which is what I export to when I'm done.) but I doubt that would cause this error.

    Disk setup is different for each computer. For my work computer working off a SATA drive with only the video content (program and OS is on a separate SATA drive).
    On my home computer, sometimes working off a second IDE drive, but sometimes working off a USB2 external HD.
    When I first encountered the problem, it was on my home computer working with a USB 2.0 HD (also my first using HDV in PPro), so I thought disk transfer speed may have been the problem. But not long after, I encountered the same problem at work while working off of regular hard drives (well defragmented ones at that.)

  • HT1689 Downloaded song loses audio halfway during playback.  Can anyone help?

    I have a MacBook Pro OSX 10.6.8.  I've just downloaded 2 songs from Itunes.   They seem to download okay.  When I try to play them, they're all okay until about a third of the way through and the audio stops.  the bar continues to move along, but no sound comes through.  I've tried deleting them from PURCHASED and re-downloading them.  Same thing happens.  Can anyone help?

    If they've re-downloaded in the same state then try the 'report a problem' link from your purchase history : log into your account on your computer's iTunes via Store > View My Account and you should then see a Purchase History section with a 'see all' link to the right of it ; click on that and you should see a list of your purchases ; find those songs and use the 'Report a Problem' link.

  • Audio pauses during playback

    Although I can't replicate the problem on my machine my
    client says that a few of the audio clips pause for a few seconds
    then continue.
    It's a glorified Powerpoint presentation with audio talking
    about each slide. Graphics are exported JPEGs from Powerpoint and
    the audio are basic mono 64kbps MP3s that have been imported into
    Director and not externally linked.
    I have a feeling the pauses are because of her computer's
    access to the CD-ROM drive as it looks for the next graphic and
    audio to load. I'm still waiting to hear from her on whether or not
    this problem is replicated on another machine. I have no problem
    with it on mine. Any other thoughts?
    Thanks.

Not usually a conspiracy theorist but geez, take a look at the threads!
    So if you are using ZenCast to download them, and transfer them, then they are going across as Motion-JPGs. Have you tried just copying over the MP3s to the device, not the Motion-JPGS. I have had some issues with the Motion-JPGs ZenCast creates. I think it has a hard time with VBR sometimes or something. But I find the MP3s play just fine.
    So, do the MP3 files play OK?

  • Loss of audio panning effects with timeline audio of Sync type "Stream"

    I have a Flash animation which is loaded into a parent master Flash file. In the animation, there is voice audio embedded in the timeline which is synced with a character animation. The Sync type of the audio is set to Stream, which is essential for the mouth movements to match the audio. When I try to pan the voice audio so that it comes only out of the right speaker, it sounds fine during preview playback, but after publishing, all of the panning effects are lost. If I change the Sync type to "Event" or "Start", the panning effects work fine, but the audio is terribly out of sync with the animation.
    The source audio is a mono audio file. Not sure if that has anything to do with it. I've tried changing the publish settings for both the parent and the child animation Flash files to be Speech, Mp3 mono, Mp3 Stereo and just about every other option, with no desirable results. I have also tried publishing and running the animation without loading it through the parent file, also no results.
    Is there some kind of rule in Flash about Stream versus Event audio and panning? Do I need to use a stereo audio source file? I don't currently have access to the original audio files, but I can get them. Are all Stream type sounds automatically converted to mono at runtime or something??
