Audio gets out of sync after export and burn to iDVD - works in iMovie

I've burned my DVD show twice on iMovie and iDVD and the audio music tracks slowly get displaced over the course of the show (15 min) after exporting and burning to iDVD. It gets pushed back so that it starts later each new track...I've locked the audio to the playhead for each new audio track - however, there are some empty gaps between the tracks, does this have anything to do with the displacement? Or should it not matter since the tracks are locked?
I had it all synced up in the playback on iMovie and had it aligned with visuals, however, after burning, it gets displaced and everything gets off...
Any help would be appreciated, thank you
Chris

The solution:
Always use 16-bit/48kHz audio.

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.

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!

Audio/video out of sync after export

My son Charley and I are working on a simple project, where we have imported an MP4 file into Premiere Pro, then edited it, with no problems, but when he exports the file (either to an MP4 or FLV), there is a small but noticeable audio-video sync problem on the exported file. There does not seem to be a sync or other problem with the source file, nor with the edited file as viewed within PP. But on the exported file, the audio seems to run slightly ahead of the video.
When we upload one of these exported files to Youtube or Vimeo, the sync problem seems to become more noticeable than in viewing the exported flv or mp4.
We cannot find a solution in searching the Forums. Charley consulted with another more experienced videographer, and they tried for hours to no avail.
Charley is using Premiere Pro CS5.5 on a Mac (MBP Mid-2009 2.53 Ghz Intel Core 2 Duo, using OSX 10.6.8).
We see lots of discussion about frame rate. Charley put the settings to 'match source' but maybe there is something else we're supposed to do.
He can post screen shots of all the settings, if that will help. Adobe provides no phone support for PP and just sends us back to this Forum.
Any help much appreciated.
Michael Lanning

Kevin: OK, that's helpful. Charley is at work until 3:15 Eastern; in the meanwhile, I'm trying below to reply to your inputs; sorry if some of my questions are illogical, just reflecting my confusion.
You say to match source settings, including audio sample rate, and (I think) that we should do that by creating a new sequence at which time we select the clip and drag it to New Item button. Perhaps doing that would make some of the following questions irrelevant, I'm not sure, but here they are:
We did not check the box "Match Sequence Settings" (just under 'Export Settings'); should we have done so?
On Presets, and using FLV vs H.264:
Do we need to leave the 'Match Sequence Settings' box Unchecked if we want to use a YT or Vimeo Preset?
FLV does not seem to have a pre-set for YT or Vimeo, but does have one for 'Web.' H.264 does have YT and Vimeo pre-sets. As I've mentioned, we have been trying to make this work with FLV, as Charley found that H.264 was giving us (worse) sync problems. Maybe we should go back to H.264.
You say that "if these things don't work, "...try an similar H.264 preset to upload to" YT. Do you mean to suggest that we try exporting in H.264 instead of FLV? (If that's not what you mean, and if we still work with FLV, then I don't know what "an similar H.264 preset" would be; do you mean like the 'Web' preset?
Whether FLV or H.264, I'm unclear how ensure audio sample rate matches source.
Codecs listed on source file are H.264, AAC; does that imply that under 'Basic Audio Settings' on Audio settings tab, we should use an AAC codec rather than the MP3 now indicated?
Should we be determining the bitrate settings of the source (ie, right click the file within PP to find the properties, including bitrate?) and then using that bitrate?
Or do we resolve all this about audio sample rate simply by creating a new sequence as discussed above?
I hope these questions make sense. Thanks again for your help.

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.

Mac OS X partition ("Macintosh HD") gets out of sync after hibernation

Hello,
I have a first-generation Unibody 15" MacBook Pro. I run Mac OS X Lion and Windows XP Profession 32-bit through Boot Camp on it.
I notice that the Mac OS X partition gets out of sync after I hibernate in Windows XP, reboot into Mac OS X Lion, restart and resume Windows XP. Certain folders would remain visible in Windows Explorer but become inaccessible, while some folders that I just created in Mac OS X would not even show up.
Is there a way to tell Windows XP to "remount" the HFS+ partition?
Steps to reproduce:
Boot into Windows XP;
Hibernate Windows XP;
Boot into Mac OS X;
Pick a folder and change something in it;
Create a new folder;
Reboot and resume Windows XP;
Open "Windows Explorer";
Try to access the folders you just meddled with.

Don't hibernate, shut XP down when you reboot and the issue goes away, you really should consider using a more modern operating system.

Tape archive DV tape: the audio gets out of sync.

I have some trouble with FCPX working with my DV tapes and camera (via FW).
When importing a .dv file previously imported with iMovie FCPX crashes. When I convert the file to prores with mpegstreamclip it will import but with incorrect date info.
Now I have made a Tape Archive from within FCPX and I can import from there, but the audio gets out of sync at the end of the tape.
Any suggestions?
Peter

I have finally figured out how to export an iphoto album so that I can maintain the proper order of the photos after burning the file. How do I keep each individual photo title and description after exporting and burning?

I have finally figured out how to export an iphoto album so that I can maintain the proper order of the photos after burning the file. How do I keep each individual photo title and description after exporting and burning? Presently after exporting and burning each photo is identified by the file name rather than each individual title description.

File name and Title are not the same thing.
Filename is attached to the Jpeg file in the Finder.
Title is attached to the photo within the Jpeg file - as is the description. These are written to the Exif and IPTC metadata on export.
So: File -> Export. Kind: Jpeg or Tiff and Check the box at 'Title and Keywords'. This will write the Title, keywords and descriptions (though not explicitly stated) to the metadata. This can then be viewed in any app that understand this material.
You can choose, if you wish, to also use the Title as a Filename - that's an option at File Name

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 out of sync after exporting into Quicktime using current settings.

Quicktime file has audio out of sync when I export to quicktime movie using current settings.
Ok for about the first few minutes then, out of sync after about 10 minutes.
I shot the footage on tape with my Sony HVR-Z7u.
My Sequence setting is the same as the format of the footage as shown below.
Pixel Aspect Ratio: HD 1440x1080
Editing Time base: 23.98
Quicktime video settings: Compressor: HDV 1080p24
Audio Settings: Rate 48 KHz
Depth: 16bit
Clip format:
Pixel Aspect Ratio: HD 1440x1080
Vid Rate: 23.98
Compressor: HDV 1080p24
Audio Rate 48 KHz
Audio Format: 16bit

I recently moved and both of my editing machines were unplugged for a couple of days until I could get them set up. After turning them back on, the problem had disappeared. Perhaps leaving the system unplugged had allowed some of the internal components to reset? That's the only thing I can think of. At any rate, the issue is gone.

DVD & Blu-Ray audio out of sync after export

When I use FCP X's built in DVD or Blu-ray export option, about halfway through the video, the audio becomes out of sync and becomes ahead of the video.
How can I fix this?

Freddy,
You will see that I am experiencing the same issue with my DVDs and BDs per my question 3 hours prior to yours. It never was an issue until very recently. I may have a solution. Realizing that my audio was acting as if I had "Drop Frame" audio attached to "Non-Drop Frame" video, I went back to my source material to verify my acquisition settings. All elements of the production were recorded appropriately as "Drop Frame." Playback on the "Timeline" (Passé now) was perfect. No audio sync issues there. So I felt it must be some rendering setting within Compressor and the render engine. When you go to Compessor (Send to Compressor), you will gain access to the audio render settings for both DVD & BD. Typically, the "Retiming" under the "General" tab of the Audio Inspector is set to "100% of source." I Went ahead and checked off the radio button below that to render the audio at the exact duration of my program (nearly 3 hrs long). I did this for the DVD version of the program and placed it into DVD Studio Pro to replace the bad sync audio. Well wudda ya know....it worked. I haven't burned the DVD yet, but that is next. I suspect that if this works for the DVD, it may work for the BD render as well. Wish me luck. I hope this helps.
On a side note: If all else fails, render a MASSIVE master file and use that in Toast to make a BD. Not the best option, but it will get you out the door.

Audio out of sync after Log and Transferring

So, I'm working on a project for school and I shot everything on a Panasonic HVX200 at 720p/24fps. I have everything saved onto a LaCie external and is connected via USB 2.0. When I go into Log and Transfer, all the clips look great and playback without a problem. But, after I "Add Clip To Queue" and try to play it back on the timeline or canvas, the audio is out of sync (it's almost twice as fast) and the video almost looks inferior.
Any advice would be great. I really want to start working on this project, since it's due Thursday afternoon.
Thanks and regards,
Christian

In the P2 Import window...in the P2 Browser, there is a little sprocket drop down menu. Click on that and choose PREFERENCES. Uncheck REMOVE PULLDOWN and then try importing again.

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.

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?
