Audio Goes Out Of Sync On Export

Hello,
Im exporting an Hd 1440x1080, 29.97, HD 1080i60 sequence to a self contained QT movie. Its about 70 minutes long. By the time we get to the toasts in the reception, the video is at least a second ahead of the audio. This always happens with my HD exports, or even if I send directly to compressor to create a BluRay. Any work arounds
Thanks
MG

1080i60 is 29.97, so no problem there.
Please list the 'item properties' of the clips (audio and video) and the 'sequence settings' you're using.
Also, dbl-check the audio rate...is it exactly 48kHz or something like 47.998 or 48.002. If it's not exactly aiff/48kHz/16bit, you could see sync issues.
But let us know exactly what you're working with.

  • HELP!  Audio goes out of sync after export!

    OK, folks. I need your help. I have a looming deadline of THIS FRIDAY to hand this in.
    I have a finished multicam edit of a show that runs 1 hr 20 min. It plays back perfectly in the timeline, all video and audio perfectly in sync. Looks and sounds exactly like what I need.
    When I export the video as an H.264 file, the audio gets out of sync with the video by 13 frames! But that's not all... It doesn't happen to the entire audio track. There's about 50 minutes in the middle of the video where the audio goes out of sync. The audio at the beginning and ending of the video is lined up perfectly in sync. It's just the middle section that gets screwy.
    What do I do?!
    This has never happened before, and I've worked a lot with multicam in Premiere Pro CC before this. Never been an issue. I tried uninstalling and reinstalling Premiere, and also deleting all media cache files, but still no dice.  I also tried copying the clips into a new sequence in the same project, copying the clips into a new sequence in a NEW project, nesting the sequence... nothing works.
    My setup:
    MacBook Pro Retina (Rev. A)
    Premiere Pro CC (latest version)
    Panasonic GH3 footage in 1080p 24p AVCHD timeline
    3 cameras & 1 audio WAV file in Multicam
    Any help would be greatly appreciated!

    OK, I figured out how to fix it:
    In Premiere Pro CC, click on SEQUENCE > DELETE RENDER FILES.
    Try exporting the movie again.
    It worked! I exported the same sequence, and it took a long while to re-render the audio files, but when it was finished exporting the audio and video were in perfect sync. I'm not sure what caused it, but this fixed it, so hopefully anyone else having this issue can save a lot of time by reading this.
    Cheers!

  • 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.

  • When audio goes out of sync..

    In FCP7, when audio goes out of sync with the video track it came from (even when they are unlinked), a red warning box is displayed on the audio track and tells you how far out of sync it is, which easily enables you to resync.
    Well, in FCX my audio went out of synce, but i didn't know it until i played back a segment i was working on, where i spliced two audio tracks and video tracks together. Right now i'm trying to fix the one audio track so that is synced up with its parent video track, but so far i'm just guessing that it's a good sync rather than knowing FOR SURE whether or not it's truly synced back up.
    Is there any kind of work around, which enables you to resync in a manner similar to  before FCPX?
    Thanks

    I am not sure if your problem has been solved already but here is the way to do that:
    select in the clip in the timeline the part were the audio should be return in sync. use the blade-tool to make that part a seperate clip.
    Higlight this clip in the timeline and use shift-F to highlight this clip in the browser. There it wil show up partially of course.
    Use only the audio and put that part under the selected clip in the timeline where you need the original audio. remove the original out-of-sync audio.

  • Audio sync problems with greenscreen  I have replaced the camera audio with my zoom recorder audio and it is in sync. When I apply greenscreen the audio goes out of sync. What am i doing wrong?? So frustrating..Thanks, Peter

    I have replaced the DSLR audio with audio from my Marantz recorder and it is in sync with the dialogue. I apply green screen and the audio goes out of sync. Cannot seem to make it work. what am I doing wrong? Thanks, Peter

    Thanks for the reply. I don't have time for this. is it time to switch to a different editor?

  • AppleTV export: Audio goes out of sync on long videos

    I am using Quicktime Player Pro to compress several long (30-90min) videos to watch on my other Apple products. The AV sync is perfect in my original movies (they are NTSC 29.97 DVCPRO50 with uncompressed AIFF 48KHz audio) However, when I export using any of the h264 presets (AppleTV, iPod, or iPhone) the audio becomes out of sync near the end of the video.
    This seems like a bug. Is there some way to correct this?

    Trim into smaller clips well under 30 minutes. Encode each separately then join them after. You can encode the clips a lot faster in MPEG Streamclip (free) and in a batch list as well.

  • 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?

  • 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.

  • My audio goes out of sync after import

    I have a bunch of masters of 1h documentaries that I've done using Adobe Premiere CS6. I've exported the masters using exactly the same specs:
    Apple Pro Res 422 (HQ), 23.98fps, 1920x1080p, 48kHz, 16b, PCM audio.
    I have to do some changes on the masters of these shows. They all play fine on several players like VLC, Quicktime, Mpeg Streamclip, etc. However after I import the masters into Premiere Pro CC, 3 out of 10 shows get the audio gradually out of sync, even on the source monitor before I put them on a timeline. The behaviour continues even after I place them on a timeline.
    The project settings are the same as the masters and so are the sequence settings. I've tried to recreate the project, delete and re-import, duplicate the file and import that, and no matter what I do the same 3 masters go out of sync after the import.
    I've tried to find a solution in many forums and despite noticing that several people have the same issue, no one has a valid solution for my problem.
    I cannot go back to CS6 since my company updated their systems to CS7 so I can't even cross check.
    Any suggestion will be most welcome.
    Thanks in advance peeps.

    Couple of suggestions.
    First, rather than opening the Master export, go back to the original project.  That should open fine in CC.
    Second, with a CC subscription, you do have access to the full CS6 suite.

  • Slideshow audio gets out of sync when exported to iDvd

    I made a large slideshow for a 40th anniversary party. It has 244 images & 7 songs. It is 29 min 54 seconds long. When I view the slideshow in iPhoto it works fine & the last image ends right at the end of the last song.
    When I exported it to iDvd, the audio gets out of sync with the video. By the end of the first song, the video is about 2 seconds ahead. By the end of the last image, the last song is cut of by about 30 to 45 seconds. I tried exporting the slideshow directly to iDvd. I also exported it as a large movie & it did the same thing.
    I'm using a 17" 1.67ghz powerbook with 1.5 gigs of ram.
    I'm using OS 10.4.2.
    I'm using iPhoto 5.0.4
    I'm using iDvd 5.0.1
    The images are scanned tiffs. I also have jpegs that I shot with my canon eos digital rebel xt.
    Anybody have any ideas or work-arounds?

    I suggest you either use iDVD to create two slideshows or use iMovie to get all 277 images and the 8 audio tracks into one slideshow. If you use iMovie after you get the slideshow/movie put together and completed quit iMovie. Then go into the iMovie project package (Control-click and select Show Package Contents). The find your movie in the Shared Movies folder and drag it into an open iDVD menu. This allows iDVD to to the rendering of the stills and give you a sharper image. That movie file you're dragging is a reference movie so leave it where it is and just drag it into iDVD's window.
    If you can live with two separate slideshow (consider it a potty break between the two) and you don't have or need the Ken Burns effect, you can get excellent results by building the slideshows with iDVD from imported stills. The sync to audio in this method works as advertised. I like to add a blank slide at the end of the slideshow so the music fades out during a blank, black slide.

  • AME - Converting to MP4 and different FPS - audio goes out of sync

    As described in the title.
    I'm reencoding a 1920x1080 29,97 fps video into a 1280x720 60 fps video. Audio is AAC 44100 stereo.
    Basicly a task that many of those free converters on Windows do smoothly. I use Mac...
    I'm surprised that it goes out of sync, like 3-4 secs EARLY sound on a span of 2 mins video.
    Settings here:
    AME CS6 Fully updated
    source: 1920x1080 29,97fps MP4 with AAC 44100hz audio
    Target:
    Codec: H264
    Saves as : MP4
    1280 x 720
    60 fps Progressive - NTSC
    CBR VBR1 VBR2 doesn't matter
    Max rendering quality
    Codec Audio AAC 44100hz (as source)
    Any ideas ?

    Because we stream at 60 fps and we have to convert all the materials we receive from our partners from the usual 29,97 to 60.
    Thanks for your MVPaluable help.

  • Audio goes out of sync when I export to iDvd.

    Anybody have any idea what this could be, and how to fix it?
    Everything's fine on iMovie, the audio syncs up fine to the video, but in iDvd, the audio seems to have randomly shifted all across the video.
    It's not all the audio, some of it is still in place (but with other sound layered over it).
