Embedded Video Audio Sync Problem

I have been exporting Flash Video from Adobe Premiere
Elements 3.0. I import the .FLV into Flash 8 as embedded video. The
published .SWF works fine, audio and video start in sync and stay
in sync, but about 3/4 through the video, audio stops.
This occurs no matter how short or long the exported clip.
I did my best searching through these forums, looking for an
answer to this issue, but have had no success.

Do you need to embed the FLV file in the SWF file? I would
recommend playing the FLV as an external file. If you need to use
embedded video, make sure the frame rates are identical (SWF and
FLV). I can't remember if Premiere Elements enables you to output
with Raw audio for FLV files, but Flash 8 (or CS3) will recompress
an embedded video's audio track on publish/export--so, try to use
Raw if you can to avoid recompression. This might have something to
do with your problem too, the recompression of the MP3 audio track
in your original FLV when re-exporting as embedded video in the
SWF. (Your audio stream setttings in the Publish Settings control
the quality/recompression of your FLV output when embedded in the
SWF.)
HTH.

Video audio sync problems resolved

I've solved my audio syncing with video problems. Maybe it will help you find your solution.
I recently installed Leap Motion but it said I needed to update my video driver. I thought my driver was up to date so for both my computers that had different video cards I updated and the syncing issues were gone.
So as far as helping you get the right update I won't be of much help. But at least this will give everyone a direction to look in and find their own solution.
I hope this helps and good luck!

Hi there
In addition to what Leslie offered (which is good advice) I've seen others report success by staging the audio to begin slightly after the slide starts. Perhaps .3 .4 or .5 seconds into each slide.
Cheers... Rick

Is there someone where the E66 does NOT have the audio/video sync problem?
Test:
Record your finger tapping on the table, then check if Video and Audio are in sync
Mine has 1 sec or more afer a few seconds of recording

Furthermore on the site, still frimware from nov last year is advertised as latest!
I will go to a service point, or return the phone to the store.

How to stop the spinning ball/pizza that is stalling repairs to project on imovie 09? on macosx10.5.8 using iomega and superspeed ext h.d. as storage for the events and projects archive of a wedding video that has had audio sync problems on all share formats (iDVD, mp4, and last of all iTunes). The project label now carries signal with yellow triangled exclamation “i tunes out of date”.
To solve the sync problem I’m following advice and detaching sound from all of the 100 or so short clips. This operation has been stalled by the spinning ball. Shut down restart has not helped.

Audio sync problem with videos imported from iPod Touch

I have an iPod Touch 4th Generation that I used to shoot video at a family birthday party. When I imported the footage into iMovie '11, the audio is not in sync with the video (video is about two seconds behind audio) and there is only the left channel of audio. I verified that the video on the iPod plays just fine--no audio sync problem, both left and right channels work. I just upgraded to iOS 5 on the iPod Touch. The iMac is running Snow Leopard 10.6.8.
As a workaround, I can import the video into iPhoto instead. When I play the video in iPhoto, there are no audio sync problems and both channels of audio can be heard. I have imported other iPod Touch videos successfully into iMovie '11 in the past few months, but this has been the first time these problems have occurred. Any help would be appreciated.

Premiere cannot handle clips with variable framerate.
Your converted clips need to have constant framerate.
Otherwise use a converter like Handbrake.

Major "BUG" in Imovie 9 - Audio Sync Problem on Export !

Well I'm a hard-core Apple user from day one, but unfortunately today I'm not to proud about the latest version of Imovie 9.
It seems there has been a "MAJOR audio sync problem on export" in Imovie 9, since July 2009. Apple knows about this bug for a long time now, but didn't release any bugfix yet!
Here's what it's all about:
It seems if you use the (custom /manual) speed-adjustments and not the preset slider speeds, you will experience (after exporting your movie) annoying bursts of audio from clips that had been set to mude. The strange thing is that you will only experience this audio-bug after exporting, you will NOT experience it in the project playback mode!
Here's what you can do:
Find ALL the clips in your Project that are Speed Adjusted.
Instead of using a "Custom Speed" percentage, use any of the "Preset Speeds"
Preset Speeds on the Slider = 12.5%, 25%, 50%, 100%, 200%, 400%, 800%
Then, export your project as usual.
No more sync issues.
Really hope That Apple will come up with a real BUGFIX soon.
It's a shame that a major bug in a otherwise GREAT PRODUCT, hasen't been fixed yet!
What's wrong with Apple?...this is not one of their finest hours.
Still A BIG fan from Imovie HD,...I'll chance to Imovie 9 when the bugs are finaly fixed!

This is TERRIBLE! I have spent so much time working on this project, and I really don't want to adjust the speed settings to the preset levels, BECAUSE I need to motion of the video to match certain musical points. I can't re-film my video, and I needed this project done TODAY. I made a music video with some kids at summer camp, and today is the last day- the day we were supposed to all watch it together, and now, I've got NOTHING!!!! (Because I can't export it without all those glitches!)
I am MAJORLY DISAPPOINTED on this one. I've made movies in windows movie maker before, and purposely used imovie, because you know, everything on macs is supposed to be better. Well, I guess I was wrong.

Premiere CS4 - Audio sync problems, Encoding Problems

Hi,
I've been using Premiere CS3 for encoding 20-25 minute videos to deploy on a Flash Media Streaming server.
Today I upgraded to CS4 and everything that I render to FLV/FV4, H264 or Quicktime format has serious audio sync problems when I use AAC as the audio codec. Unfortunately for me, AAC is the codec that I need to use for the streaming server. The audio is synchronized to begin with, but it gets progressively unsynched as the video progresses.
Has anyone else had this problem? I'm using bitrates of 256 kbps, 512kbps for the video and 24 kbps / 32 kbps for the audio.
Another thing that I've noticed is that many of the options that I used when encoding videos are no longer available!! For instance, I cannot generate hinting tracks for Quicktime, and most of the audio frequencies are gone for Quicktime as well.
What a disappointment:(
-Chris

Seems to be an on going issue with no response from Adobe. Have the same issue with the audio running ahead of the video. (Cool if this was an old Japanese monster video).
Running CS4 PP & AME all updates are current. Nvida Quardro CX (current drivers 4.20.006) used several formats (Elemental h.264 to MPEG-2) same issue.
PC Intel Xeon CPU 3.20GHz 16GB RAM – Prof Win XP x64 Ser Pack 2
Any help from Adobe would be appreciated.

Audio sync problem after scrubbing

I'm trying to piece together some clips from a TV series called Legend of the Seeker. I'm using Premiere CS4 4.0.1, Vista Ultimate 64-bit.
Placing the hour-long video in the Source Editor allows me to play the video fine from beginning to end, but if I start scrubbing through the file, the audio unsyncs itself immediately.
Here's a screenshot of the video in GSpot:
http://img14.imageshack.us/my.php?image=premieresync.jpg
Setting IN and OUT points and then dragging a very small clip into the timeline has the same result.
Any ideas would be very appreciated.

You are actually pretty lucky to just have Audio sync problems, though I do not know why scrubbing would make any difference. With both Xvid and DivX one more often gets no Audio, or no Video.
Agree 100% on the 3rd party conversion, prior to Import into PrPro.

CS4 audio sync problems

Hi all,
sorry if this question is old hat - I've searched the forums and can't seem to get a clear answer (most refer to CS3 and before) so thought I'd ask anew.
My preview in Premiere CS4 is fine, as is the preview in Encore CS4. The video was captured from four tapes (HD as mpeg and SD as Matrox AVI) in Premiere. The final DVD (10 minutes) consists of 21 clips. All but one are OK - this one has the voices well out of sync with the video, even though other clips taken from the same tape are fine.
I also had a major problem recently with an MP4 from youtube, which I guess is the same issue - everything else was fine, but this one clip was well out.
I'm guessing by now this is an old problem. What's the solution, please?
Thanks
Paul.

Newbie to Adobe here ...
Okay, so after spending over 14 hours trying to fix the audio sync problem I fixed mine. After editing my project I selected Sequence > Sequence Settings > Playback Settings > under Realtime Playback make sure the "Desktop Video Display During Playback" box is selected. Next, in "External Device" change the setting from "None" to your next option. Mine reads DV: 29.97 720 X 480i. Next, Under "Export" section in that same window select the in "External Device" select the DV option again. Also, you might want to "Disable video output when in background" ...select that box at the bottom of the screen.
Now, try recording the video to the tape ....my audio now sync's as normal. I hope it works for you.\
One more thing ... you can keep the "Desktop Audio" button selected.

Audio sync problem downloading VHS-C

I've downloaded a straight VHS tape (with no audio sync problems) into final cut pro once I had changed the Camera setting to 32Khz and the capture and sequeence presets to 32khz as well (it was all aout of sync when the settings were 48Khz).
The problem now, which is driving me MAD, is I have 13 hours of VHS-C tapes, which I have put into a VHS cassette converter to download and the audio is out of sync. The capture presets are the same as above (i.e. 32KHZ) . Why is this? I downloaded them initially at 48Khz (settings on the camera 48Khz and FCP at 48Khz in capture and sequence settings), but this was also out of sync.
Why is it different from one VHS tape to a VHS-C tape?
I hope there is a God out there that can help with this one?
Thanks!

Eagleray:
I capture through a ADVC-100.
I use to find the same problem playing VHS tapes with a standard VHS player from time to time and never solved it. The out of sync audio appears when capturing some specific tapes from specific sources:
- All my home tapes recorded in my old VHS recorder shows a audio problem; not specifically out of sync, but some audio "cracks" from time to time, like an electronic noise. No way to find a capture setings that works.
- Some customers VHS tapes that showed the out of sync (no noises) and again, no combination of digitalizer settings made it works. Had to resync the audio editing and stretching in an external audio editor or cutting shorts parts and syncing them with video. The our of sync appears in small captured portions, like 10 min or so.
- Never found a sync or audio problem capturing from VHC-C (the small VHS tapes) playing them with the tape adapter in the player.
I google long hours about this problems and all that I learned is that some old VHS recorders had not a "synchro" signal in the tape.
As I told you, I don't use any pro VHS deck, just my consumer "state of the art" VHS home recorder.
I hope there is a God out there that can help with this one?
I don't think HE visit these forums.

Audio Sync problem iTunes Festival

Audio Sync problem when watching iTunes Festival on Apple TV3. Other video's work fine. Anyone else experiencing the same? Any solutions?

Hi There,
The same problem is happening with me as well. I keep getting the "analysing audio" message and my clips are 24 or 25 frames out of sync.
I am currently working on a mixed format project - DVCAM and HDV capture into a DVCAM sequence. The DVCAM clips are causing the problem. The HDV clips are fine. I wondered whether it might be a mixed format issue - switching between capture codecs within the same project? Is that something either of you guys are doing? What camera was the footage recorded on. The pictures I'm struggling with were recorded on an Ikegami and I'm capturing from a sony deck.
I have found an easy workaround. Put your entire out of sync clip into the timeline. Correct the sync then drag it back to your bin. You'll get two clips with the same name which is a tad confusing but the one you've dragged back will at least be in sync.
I remember having this problem years ago without explanation. It hasn't then happened for years until now.....
I'd be interested to know if you get to the bottom of it.
Good luck,
Richard

Audio Sync Problems With Share YouTube -- OSX not iOS

I've replicated this several times. It's maddening and bizarre. *Share YouTube*
Exporting a FCPX video using the "SHARE" menu and choosing YouTube causes the resulting upload to be out of sync when viewed in Safari or other browsers on iOS
Viewing the same video on the iPad with the built in YouTube app, the video plays in sync
Viewing the same video on AppleTV 2 (with the 5.1 update), the video plays in sync.
If I export using Export Media menu item under the SHARE menu, and then from QuickTime Player choose Export For Web (under the File menu) and manually upload, the video is in sync.
Note, that using
Feel free to try on this short simple and silly video http://www.youtube.com/watch?v=cGTQNMJdPRQ&list=UUiDxioBFJCPC-8OUFifsx8A&index=2 &feature=plcp
Anyone else experience this. Is this a bug or a feature? Rather not go through three steps to upload a simple YouTube video.

We've got the same problem and yep, it's infuriating that are so few posts about it.
It doesn't happen with every video, but the vast majority of files that we've tried to either export directly to YouTube from QTX or export locally and then manually upload to YouTube end up with shockingly bad audio sync (and also some colour issues, but that's another story).
As a small video production company we were chuffed to bits with the improved export speed in QTX and quick to make use of it. But when we realised there was a problem, we had to revert back to using QT7's painfully slow export.
We've run experiments on a brand new iMac and MacBook Pro running the most up-to-date version of OS X and still no joy. Always the same audio sync problems with the same video files.
In the meantime however, we've found that the settings advised on this YouTube help page have given us the best (albeit slow) results at both 25fps and 30fps when exporting from QT7:

FCP: AUDIO SYNC PROBLEM

i have audio sync problem -- of the finished product which didn't have that problem before. does anyone know how this could have happened? in my earlier posting, there was a warning window which i played around w/ and now i have an audio sync problem in my prior projects.
please help me.

The Reels, are indeed the 5 surround channels. I have a feature that is broken up into 8-10 minute sections. I did this because the composer was using a G3 at the time and couldn't handle the whole movie at once. They are 16bit 48khz aif files exported from ProTools. The biggest thing here, is that at one point everything was in sync. I am trashing the preference files now to see how that works.
It's not a playback issue as well. When i scrub one frame at a time, the sync has drifted off later in the clip. It's very strange.
In my previous post I said the one of the Reels was in sync. That was because I recreated it, by making a new project and copying the video from the timeline, and re-importing the 5 audio streams. It didn't work for any other reels though. it is still out of sync in the main project.
Trashing prefs did not work.
Also, I tried a lot of the things in that technical doc, but non of them worked including trashing prefs.
The real weird part is that the Audio file SAYS it is the same length of the video, but the audio ends later. It's in sync in the beginning but not at the end.

TS1363 Audio Sync problem - Audio is late, after a scene people are talking and audio does not relates

All the TV shows purchased and downloaded have AUDIO SYNC problem. This does not happens with any other video I watch from other sites, i.e. ABC, NBC, Showtime, all which I watch with no audio problem.
The audio is always late, people are talking and scenes change and the audio belongs to the past! Please help me to solve this!

hi vcp
welcome to the forum, glad you made the switch ... you won't be sorry (although you might be wondering at the moment!)
1. nothing wring with that
2. no
3. just don't install 3rd party crap you don't need ... and don't install any anti-vrus software
4. no special settings required
what camera did you capture from? did you capture with FCP?
cheers
Andy
