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?

Why does the audio go out of sync on my Apple TV?

Over the past couple of weeks I have noticed that the audio goes out of sync with any streaming video on my Apple TV (3rd gen) after about 20 minutes of usage. I have never had this experience in the past and am not sure why it is happening, but one theory is that it has something to do with AirPlay. I'm pretty sure that this problem only happens after I use AirPlay to connect my Mac to the Apple TV. I'm not sure if this is the exact source of the issue and was wondering if anyone else has experienced this, and if so, what solutions may be available. Thanks.

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.

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.

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 slips out of sync

Importing straight from my .mts or running through media encoder first (to .mxf), either way, the audio always slips out of sync. I'm testing Premiere CC currently to see if it will meet my needs, but I have little confidence it will with an issue like this. If other programs I'm testing (Vegas, Lightworks, and Edius) correctly detect my video/audio settings, why should Adobe be the exception?
The file is .mts from a Panasonic GH1, shot at 1080p 24 (23.976). This is correctly detected according to the sequence editor properties panel (although not as AVHDC). Changing to AVCHD does nothing to alleviate the problem, however.

First off, yes, I've tried importing the way described in the link(s). I've played with this endlessly it seems. I do have a workaround and can get my audio to sync, but it's very manual and time consuming if done on a large scale. I must unlink the audio (actually I'm usually working with a separately recorded audio file), and finagle the time/length/play speed.
What version of Premiere Pro? Include the minor version number (e.g., Premiere Pro CS5.5 with the 5.5.2 update).
Latest CC version 7.2.2 (at least it's the latest according to the CC downloader)
Have you installed the recent updates? (If not, you should. They fix a lot of problems.)
See above
What operating system? This should include specific minor version numbers, like "Mac OSX v10.6.8"---not just "Mac".
Win 8.1 64bit
What kind(s) of source footage? When telling about your source footage, tell us about the codecs, not just the container types. For example, "H.264 in a .mov container", not just "QuickTime".
AVCHD .mts file from a Panasonic GH1 (both from a single file, minus the whole folder structure, and from one copied the "approved" AVCHD way from within the original unchanged folder structure)
If you are getting error message(s), what is the full text of the error message(s)?
None
What were you doing when the problem occurred?
Nothing special
Has this ever worked before?
Not from what I can tell (again, I'm trialing the software here)
What other software are you running?
Web browser sometimes, but same issue when nothing else is running
Do you have any third-party effects or codecs installed?
Well, yes, on my machine of course, but nothing I've put into Premiere
Tell us about your computer hardware. Be especially certain to tell us about third-party I/O hardware (e.g., AJA, Matrox, Blackmagic, MOTU).
Core 2 Duo (I know, I know . . .), 8gb memory, NVidia GeForce GT 520 graphics card
Are you using Mercury Playback Engine GPU Acceleration?
Yes
Does the problem only happen with your final output, with previews, or both?
Everything, even before actually importing and simply viewing in the source monitor
Thanks for any attempts to help.

Nightmare with repaired AUDIO slipping out of sync ???

I have a concert shot on Sony camcorders 48Khz, and audio recorded to LOGIC PRO 44.1 Khz
My workflow is roughly this:
1. Log and Transfer footage into FCP.
2. Arrange the clips into a rough edit on the timeline.
3. Export the camera audio from FCP, as it is on the timeline. ( to 44.1 AIFF file)
4. Sync up the good audio in LOGIC PRO to the camera audio track.
5. Bounce the good audio in LOGIC PRO ( to Both 44.1 and 48 AIFF files).
6. Reimport the good audio track into Final Cut Pro, to replace the camera audio.
Logic is working in 44.1 as that what the multi-tracks were recorded in...
I tried importing the 44.1 and the 48 and both do the same
Theoretically, this should sync everything, lThe problem is the "good" audio from the Logic slowly slips out of sync with the camera audio.
BUT !!!!!....The WAVE FORMS SHOW THEN IN SYNC ????????
It just plays back a little faster....??? and goes out of sync
Another clue is that when I export the audio from the rough edit in the timeline (step 3), I can reimport the file that FCP produces and, when I put it on the timeline, it exhibits the same behavior: The exported audio track from FCP slowly slips out of sync with the EXACT SAME audio track on that's already on the timeline. How could it be slipping out of sync with itself after an export?
What a pain ??????

the Wave form is looking correct and all in sync
So, (to confirm) the audio waveform is syncing with the video?...very strange situation with the playback/sync.
Have you tried running Disk Utility/Repair Disk and/or trashing prefs? (I realize trashing preferences is a bit of a pain, but it does resolve many issues).
How full are the harddrives? What drive(s) is your media on and how are the drives connected?

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.

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.

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.

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!

Why is my audio going out of sync?

Hi
I have a .mp4 clip I want to import into FCE. I use convert using quicktime, select dv-pal & 25 FPS.
The video file looks great, however it hasn't touched the audio and sound and picture are now out of sync.
What am i doing wrong?
Thanks

Check that the audio and Seqeunce settings for audio are the same.
FCE only uses 32 or 48 kHz audio depending on the Easy Setup chosen which governs the FCE Sequence.
BTW: Any audio coming to FCE should be aiff. 48 kHz is best.

Why is my audio is out of sync with my video on hd capture from sony camera

My System

Asus P5Q-E Motherboard
4 GIGS DDR Patriot Ram
Pentium quad 2.8
Ati Video Card
Onboard Audio
CS3 Premiere And Encore
I have a Sony HVR Z series HD camera from sony. I will capture a tape and it will be out of sync. I will then recapture and it may be in sync or not, this is really frustrating especially for music videos and weddings, actually a nightmare. I'm not quite sure as to the reason as it happens in Adobe Premiere cs3 and cs4. I have updated everything. Do you thing I need a 10000 RPM os system drive. Any help would be appreciated.
Joan

I have 2 Sony HDR FX1 and 1 Sony HVR Z1U and it works great in both CS3 & CS4 so something is wrong with your setup or camera.
I only have a 7200 SATA drive for capture.
I dont know if a bad cable would cause this.
Harm has a couple other ways to capture that he says it keeps the audio in sync better but I have yet tried it but im sure from what I have read here that it works good.
Here is a link to his Tools Article.
http://forums.adobe.com/thread/504907
Here are those 2 capture ways:
Capture
Scenalyzer: http://www.scenalyzer.com/main.html for capturing SD material
HDVSplit: http://strony.aster.pl/paviko/hdvsplit.htm for capturing HDV material
Hope this helps: Glenn
EDIT:
I have an 5 year old system.
On Bills PPBM4 test you can see that I scored second to LAST on speed so even my system can capture fine.
http://ppbm4.com/Benchmark.html
Take the test and see how your system is running. It doesnt take to long.
