Audio/midi out of sync when project moved from different computers

i work on logic with both my imac and macbook. when i move project x from one to the other machine (in either direction) the audio and midi get out of sync. as i do not do things to the grid, i can't specify how far things are going out of wack. recording delay settings are the same, as are those for buffer size, etc. I am using a Duet interface with both machines.
any help is greatly appreciated!

Hi,
Have had the same problem but with Powerpoint. All I could imagine is that this problem has something to do with the difference of the internal speed of the Imac and MacBook Pro. Solution: nothing but always working on the same machine (for me).

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.

Audio is out of sync when placed in the timeline!!!

When I play a clip in the viewer, everything is fine, but when the clip is placed into the timeline and played in the canvas, the audio is out of sync by about half a second. I noticed that even when I view the sound waves, what I hear does not match up with where the playhead is. This is extremely frustrating and I have currently resulted to physically moving the audio to match it up, something that I do not want to do for the duration of my film.
I read in another post that the video and the audio could not be at the same level. How can you tell if the video and audio are at the same level??
I have FCE 3.5 if that makes any difference. Any help would be much appreciated!

How was this clip imported? If it was captured/ingested, did you make sure that the sample rate of the capture settings matched the sample rate of your audio? Normally FCE will give you a warning if they don't match, but it can't hurt to make sure.

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.

Audio goes out of sync when Blu-ray folder is exported from Encore CS6

I compile a project in Encore using H.264 and .wav files. The audio plays fine directly from the timeline. It also plays fine when I preview it from Encore. When I finally export it as a set of Blu-ray folders, the audio exports out of sync with the video. It is approximately 6-7 seconds ahead of the video. What am I doing incorrectly? When I mux the files into an .MKV, the video is in sync with the audio so I know the files themselves do not have different start times.
I am running with an HP Z820 with Windows 7, 64-bit OS and 16GB RAM.

For anyone who's interested, I found a solution to this problem. Once imported into Encore, the leader in on the video and audio files cannot be trimmed at all. (I had been trimming the beginning of the video and matching audio file to eliminate the 8 seconds of dead space at the start of the clips.) Although the trim took effect immediately in the Encore timeline and I could also watch it in preview in sync, exporting was another story. The audio track seems to retain the trim when exporting but the video track does not, hence the 6-7 second delay between audio and video.
I reimported the files to my project and left in the 8 seconds of dead space at the start and voila! The video and audio match up when exported.
Ideally the trim tool would just work as its supposed to through export and all, but at least I found a solution I can work with.
(As a note, the trim works just fine in export on Encore CS5. I only had this problem with Encore CS6.)

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.

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?

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/Video out of sync when exporting to MPEG4

I am working on a project that is being edited on FCP 5.1.4
Anyhow, there is problem when exporting to MPEG4- the audio/video is out of sync.
Sequence settings show 29.97 editing base with 48 mhz sound, which is the same as the MPEG 4 settings, but they are not in sync. Anyone encounter this problem? I've never had this problem before previously.
Thanks
Caitlyn

Hi Harm,
last time you suggested the same but I wouldn't know how to take the BM card out of the equation. I only have on station. If I export to Beta SP there is no problem.

Audio Drifting Out Of Synce when Exporting to Quicktime

Using FCS2 and all material is HDV 1080i60 with audio 48k. Everything in my sequence plays and renders fine and is in sync. When I export to quicktime movie using current settings the sound goes slowly out of sync so that by the end of the project the sync is horrible and the actual project is short 11 or so frames??
Any suggestions?? I have always done this in the past with no problems but since switching to FCS2 I have had nothing but problems when this comes up.

I had a similar problem when I exported a 20 minute video to an .flv Playback looked and sounded fine but the .flv file direct out of Final Cut was out of sync with audio. I finally used the Render Manager under tools to remove all renders for that sequence and then just re-rendered in one shot. That export was clean. I had tried to break renders and re-render them but it didn't work, but the Render Manager seemed to fix what ever caused it. I haven't noticed again since on any other projects. Good Luck.

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).

Audio/video out of sync on project, raw okay

Okay, I have a project where the Audio and video get out of sync in cs5, but the original file is just fine.
So, my file is an mpeg 1440/1080 4 hour 40 minute, 53Meg file. When I preview it in a viewer like media player, it plays perfect, no video/audio
sync issues.
But, with this file in a Pro CS5 project, the video/audio lose sync. I have found this has messed up a lot of my final products which I had not seen.
So, any ideas?

Have you installed the recent updates?
There was a bug fix in a recent update for audio/video synchronization issues. The bug was in the indexing and conforming phase, so you would need to clear the media cache and re-index the assets for the fix to take effect.

Audio timing out of sync when previewing or published.

Hi all,
The issue I am having is when watching a preview or published cp4 project, the audio timings are out from the start.
This issue is not only on projects i have created but if i watch someone elses project the timing is still out
However if i use a collegues terminal the projects will play fine and in perfect audio sync.
I guess there is a issue with my terminal/captivate.
Any help or advise would be great as it is making life hard having to watch all previews on another terminal.
cheers
Lee

How was this clip imported? If it was captured/ingested, did you make sure that the sample rate of the capture settings matched the sample rate of your audio? Normally FCE will give you a warning if they don't match, but it can't hurt to make sure.

Audio is out of sync when importing mp4 into premiere pro CC, how to fix?

Earlier versions had this problem, but while I was working with CS6 it was never an issue. Now it is an issue again. It is not simply the issue of audio lagging, or I could fix that by unlinking and adjusting. The audio is fine in some areas, lagging in others. Sometimes it is the video that is lagging and not the audio. The clips are perfectly fine outside of Pr.
Dimension: 1920 x 1080
Codec: H.264, AAC

Please help me figure out what is going on? I would hate to have to begin reencoding all of the files of this camera, just because of such a glitch.
Thanks

Audio out of sync when playing HD content

Hey
I've got an issue with the audio gets out of sync when playing some HD content. I've tried to make sure the video is stored on the Apple TV so it can't be the network connection.
I've also tried a full reset of the unit, but still no luck.
But it's all video clips that has this problem. Even though they encoded the same and so on, some videos audio get out of synced and some don't.
Also have a problem with m4v files locking the ATV (and iTunes for that matter), but renaming it to a mp4 file seems to solve it. But if someone has a fix for that as well I'd much appreciate it.
Many thanks in advance,
Jeaz
EDIT: I have tried to use component cables instead of HDMI, but the problem remains. Of course also tested the video on my Mac and no problems. A quick pause and resume usually solves it, but only for a minute or so.

What sort of specification is the video content? Is spec too high for AppleTV.
It may be that it's some kind of bug in AppleTV's playback, that the Mac does not exhibit, or an issue with encoding that causes a problem only on AppleTV.
If you are encoding video and using same as source for the frame rate, it may be better in some cases trying explicitly to specify the frame rate required in case automatic frame rate conversion is introducing some kind of timing issue. Test a short clip to see.
