Help please... Audio sync issues going from iMovie to iDVD (iLife '09 packa

I've tried technical support, I've tried looking online but nothing seems to have helped, so here's the problem:
I have a video/movie, that is around 58 minutes long, I share it to iDVD and the other media formats from iMovie. The vid has music, transitions, titles, credits, etc... It plays fine in iMovie while I am editing it. The problem comes when I try to export it to another media format and to iDVD.
There's a section that has major audio sync issues that I have no idea how to even begin to fix. There is audio and music from the 55 minute mark that plays over the 27 minute mark for a good 3 minutes of video and audio.
I've tried some of the suggestions I've come across but nothing seems to work. Does anyone have anything that they can offer this very frustrated guy? Please and thank you in advance.

I don't shoot 12 bit audio (ever) so I'm not an expert on fixing it or converting it back to 16 bit audio. I can only report what others on this forum claim to have worked (in some cases with marginal success).
The ones that comes to mind are:
1. video and audio extraction in an attempt to re sync.
2. exporting back to the camera from iMovie and then re-importing as 16 bit.

IMovie 6 Audio Sync Issues

I have a Canon HV10 HDV camcorder and I am having issues with my video and audio being out of sync in iMovie. I have not attempted to move the movie to iDVD or QuickTime. My movie is a little over 28 minutes. I have the limit scene length setting set to 2 minutes. I am recording in 16 bit audio - not 12. I have made a few very small movies with this camera without issue. This is the longest movie I have imported so far. I have about 66G of hard drive space prior to import and about 48G after.

Kurt,
I have been following this thread and although I have a Sony HC-3 I share your pain. I do not have audio sync problems after importing its only when I add transition between clips that I have sync problems.
The long and the short of it is that there seems to be an issue with any and all HD content with iMovie. From what I can find here and on other forums is that the audio sync issues comes in a couple flavors.
1. Audio sync with 12 bit audio. iMove does not like 12 bit audio stream, find out what kind of audio stream your camera has, many have 12 bit audio to allow for stereo sound with minimal space on the take, 16 bit takes up more and usually is mono sound.
2. Even 16bit Audio streams have issues with HD content. Not so much when you capture its when you perform any editing that involves the transition of audio where iMovie must manipulate the stream in some way.
Now with that out on the table, what is Apple's position on this?
Items they have had me try:
Clear the Cache's and settings, re-install the program (iMovie), and the last thing they told me was, "Well iMovie is not a professional product and it is not going to be perfect".
My opinion is that they have not or will not attempt to research this issue because they do not feel it is a wide spread issue OR they are working to develop the newer version and hope that resolves the problem.
Lastly I have Final Cut Express HD, and I am here to tell you it does not express the same issues as iMovie although it take a little more effort to produce the same results than it does with iMovie.
I am confident that there will eventually a solution for this an other issues, it just takes time and effort on others to resolve. I am grateful to others here in the forums and I know Apple support keeps their ears to the pavement when it comes to the forums, but lets face it unless many. many people contact the Support department with Apple nothing will get done. It's next to impossible for everyone here to experience the same issues you and I are having, so that is why these forums are so useful. People helping people, keep up the good work everyone and I know I am grateful to any and all help that is given here in the forums by others willing to take the time to share their knowledge and expertise.
Thank you!

MP4 Video from Flip Ultra having Audio Sync Issues

All of sudden I've started having audio sync issues with the mp4 footage exported from the The Flip Ultra camera. Ive tryed the mp4 footage in both windows 7 and Mac OS X and i'm having the same audio issue but when I watch in the flip software or in iMovie no issues. Any know why this has just started happening?

Work through all of the steps (ideas) listed at http://ppro.wikia.com/wiki/Troubleshooting

FCP audio sync issue, attempts at fix result in dodgy files - help!

Hello,
I have some Sony EX1 footage here in which 20 out of 500 QT files FCP will play the audio out of sync by either 14 or 19 frames (picture lags) - when shooting no changes were made to settings which were as follows:
1080/25P HQ 16-bit 48Khz
weird thing #1: only FCP will exhibit the out of sync problem, QT or even quickview in the OS X finder will play them back fine ...
weird thing #2: once I export the footage without re-syncing it it will then play fine again in QT/finder and will sync fine in FCP - yay! - no... it will beach ball and/or lag/crash FCP/QT/finder once I attempt any sort of movement/scrubbing in any of the timelines
attempting to work with the original un-synced footage and unlinking the audio (and correctly syncing it) as a workaround has failed as whenever I put on any video effect/transition or whatever the effected part will sync correctly and my smarty pants re-sync therefore makes it out of sync again ! arrrrgh!
Basically, anytime I effect or export it the sync issue goes away, but I am left with crashy/corrupted files ...
Any suggestions ?

the audio clip is the same length as the video clip. it is not a matter of moving the audio over to sync it up. the audio falls behind by the time it gets to the end. it is just fine at the start of the video and out of sync at the end. If I would sync up the end then the front will be out of sync. All I did is capture the footage from my deck to FCP and then placed it in the time line.
Russell
This is not correct but it's easy to arrive at that conclusion. The two clips aree not the same length by your definition: *the audio falls behind by the time it gets to the end*
Mark the place where the audio ends, mark the place where the video ends. They are different and that difference is a simple matter of subtracting one timecode location form the other. This means the audio was shot at a different sampling rate than that with which it was captured. I do not know anything about the DSR400 camera or your deck, my Sonys are different, but you should be able to ascertain the sampling rate of the audio by checking the data display. If, indeed, it's 48k, you have sent the audio to a separate folder than the video and your disk cannot keep up. But that sync difference is not absolute so it's going to be different each time you play it back.

Quicktime audio sync issues

Hello,
I have quicktime version 10 (128). I can't get anything to play in it without there being severe audio sync issues every time. I can't figure out why. Can someone please help me fix this problem?
When I export my movies from imovie to quicktime it will play in quicktime, properly and without sync issues, for a really short period of time - seconds. But after that, the audio no longer matches the video. I know it's an issue in QT because when I upload the video to YouTube there are no audio sync issues whatsoever.
Help?
Thank you so much,
YahYah

I am dissapointed to see that no one has addressed this issue. I have similar issues.
The MP4's play perfectly in the quicktime player but in Premiere they are off by varying degrees sometimes up to a minute even. I had similar problems in the past with files from the same producer. However last time I was able to change the extension before importing and then sync them up manually on the timeline. It worked everytime. This time however when I change the extension Premiere brings it in as an audio only file.

HELP! Strange sync issue

This is by far the strangest problem I have come upon and
can't find anything in any forum discussing it. My site is
www.aloversscent.com. We are trying to put up 4 videos. I am
editing in FCP and compressing in Compressor to H.264 and then
making the files flv files to bring directly into Flash. All of
them are working fine except for our third episode, Operation Fox
Hunt. The audio sync is going off when the title cards come up,
about a 1/3 of the way through the video and only then. I went back
and made new exports where I tried filling in the blank audio
pieces under the cards with Slugs, I tried creating the title in
LiveType and then transfering it over instead of using the FCP
title cards. But neither worked. The strange thing is they work
fine when I play them in Quicktime. It's only when they play in
Flash that they get out of sync. If you scrub through the timeline
they will sometimes match back up again but while playing they
always get out of sync. I have run out of answers and need help
bad. Please let me know if you have any ideas.

Naw, just tell us what your sequence settings are and what your original codecs are or were. It's easy to transcode or to shoot incompatible or wrong audio sampling rates.
Clip: HDV 1080i60, 1440x1080, Upper field first; Linear PCM 24-bit 44.1khz
Sequence setting: all standard easy setup for HDV 1080i60
The difference between 2 and 20 percent is a complete order of magnitude and that kind of discrepancy sends us to totally divergent debugging paths and wildly silly suggested workarounds.
You are right. My initial wrong judgement was based on which selection I thought I was seeing at the time.
If you convert, as Christina suggests, you may still need to alter the speed of your audio track to match the length of the video.
The audio is not the only problem. Even with no audio (just a video track extracted by QT or MpegStreamclip and saved as a self-contained movie) the video stops short; i.e. by minute 10 of a 10' clip material from earlier is still playing, and the rest is missing. All other apps see the video just fine.
I already tried converting the audio to the proper rate in QT and recombining the two. But again, this problem with the video is there with the audio stripped as well.
Oh, and also: the problem is there in the viewer as well, before adding it to the timeline.

Audio Sync Issue on Export

Hello,
I have an issue with an export that I am attempting to do. I have used 50 still photos (psd) and created a slide show in after effects. It is working well. I attempted to create 4 comps made from standard dv footage. 720 x 480 from video cameras in the 1990s. I need to export out eventually to 1920 x 1080 for showing on our TV channel. It would be a .m2t format. When i attempted to do a test export, everything worked fine....the photo comps were good, the only problems were the video clips that had video/audio sync issues.
I am not sure what the problem is exactly. I feel my workflow is not right and that is leading to this issue.
I created the 50 slide comps in AE
I then used the hour long DV clips in PrPRO to make sub clips (about 30 seconds each, total of 8)
I rendered these out to then import into AE
imported into AE and made comps out of them
then render out a test file that would be my finalproject in mpeg format.
I would like to not render the video a second time and would like, basically to take my AE photo comps straight to prmiere pro to insert the DV footage but don't know how exactly to do that.
Is there something that you can recommend.
Thanks,
M

We need to know a lot more to help you. Please provide answers to the questions listed here: "FAQ: What information should I provide when asking a question on this forum?"

So frustrating that nobody knows why. Audio Sync issue.

I have an imovie project of old family footage that was ported over from VHS through a sony dcr pc120e mini dv cam straight through to intel imac via firewire. The imovie project is flawless and the sound is perfectly in sync. ive exported to idvd and when finished the audio is out of sync on the final disk. Now i have been reading about this issue and see that people blame idvd8 but it happens when i make a dvd with my imovie project using toast titanium 9 too. Surely if it plays perfectly as an imovie project there must be a way of transferring to dvd without audio sync issues. If anyone knows a solution or piece of software that will remedy this please please let me know as i have wasted about 12 dvds in various experiments.

camcorder on 16bit, i am using a vhs player attacthed to camera then firewire to imac, ... the imovie project is perfect in everyway. Everything is pal. Yes i did export to QT within IM and this was also out of sync.
thanks for answering some of my Qs ...
there's one thing, I do suspect, which was a 'source' for sync-weirdness for years.. which is the AUDIO connected to some video.
you told us, video is 25fps, and audio is included 16bit (which is good...)
I assume, adding some NON-conform audio could cause trouble... (as a 12bit audio would cause outofsynciness) .. we do know very little about, how iM08 handles audio+video internally, we 'Silverbacks' had long discussions about really weird side effects as a 'zooming' of dvfiles on export etc. I wouldn't be surprised, if adding some non-iTS, non-48kHz-aiff, non-whatever... causes such an effect.
so, please answer my audio Q from above: source, format, bitrate...?
and just for curiosity: how long is your project in total? hh:min:sec?
==edit==
pops into mind: in iM vers3, there was some 'bug', concerning PAL wrong audio and NTSC good audio ... wow < scratching bald head > .. try to contact some wiseguy with better memory..

AME CS6 Audio Sync Issue

I was recently in the process of mass converting all of the old video podcasts I help produce from an old m4v format to a newer mp4 format. Both formats are essentially the same (H.264 & AAC audio), but they vary slightly in frame size and bitrate. The difference is that the the old format was the standard for Apple's earlier devices (such as the original Apple TV), and the new format is used for Apple's later devices, as well as Android devices, and is generally more user friendly.
At any rate, I created a Watch Folder to accomplish this, and let it run overnight. Came in this morning to find that the audio was not in sync with the video on the vast majority of the files. I created my own preset, but while I was attempting to solve the problem, I discovered my preset was exactly the same as the Apple presets.
I've tried several different Apple presets, taking the watch folder out of the situation, and playing the files back in different players (Win Media, QuickTime, and VLC). Doesn't matter what I do, nearly all files with audio/video sync issues ranging from a few frames to several seconds. The only way I've found to stop the sync issue is to put the old file on a Premiere Pro timeline and exporting that sequence. But obviously that ruins the whole purpose of Watch Folders.
Anyone happen to have a similar issue and/or have found a solution?
Specs:
Windows 7 Pro x64
Adobe Media Encoder CS6 v6.0.1.31
AMD FX-8120

I do agree it is the wrong way to go about it, but all of the original projects are FCP 6 projects, and the media has either gone missing, no longer linked correctly to the project, or on DV tape somewhere. On top of this, I no longer have Final Cut installed, and my manager for whatever reason decided not to save DV deck or two when we migrated to XDCAM EX. Premiere Pro does have an FCP XML import feature, but it rarely works perfectly, so even if I did manage to find all the media, I'd have to spend hours correcting the timeline. Essentially more work than it is worth.
BUT, I accomplished exactly what I wanted to do with Handbrake. Does it look bad? Yes, but most people will be watching it on their 4" phone screens anyway.
Regardless, I may have found a bug that should probably be corrected... I'll submit a bug report on the pre-release forums if 6.0.2 doesn't fix it.

Are the audio files being brought into Flash as FLV?
The only audio sync solution I have found is to set the MP3
compression to
anything higher than the default of 16kbps (Publish
Settings).

Severe audio sync issues with DVR and RAI(Italian) channel.

Having severe audio sync issues with the Motorola QIP6416-2 while
watching RAI(Italian) channel. The audio is about 2 seconds behind
the video. This is the only channel it seems to happen with.
I just switched from Cablevision about a week ago and never had a
sync issue with their DVR with the same RAI channel or any channel.
I've tried changing hdmi cables with no success and I also went to
component video cables but the problem remains. Resetting the
box helps but within 15 minutes the sync issues return. Also,
a channel change and back helps briefly,
The only new piece of equipment in the mix is the Motorola DVR,
nothing else has changed. The DVR is connected directly to my
tv.
Any help is greatly appreciated.
Mike

Being a foreign channel, there may be something screwy with the framerate (PAL conversion?). I don't personally subscribe to any foreign languages channels and I doubt too many on this forum do either, so you may have trouble finding someone to replicate the problem on their end here.

Hi to All, My wife still has ios 6 on her ipad (she likes the look). I will do the 7.1 upgrade when it is released. Should there be any issues going from 6 directly to 7.1? Thanks!

Hi to All, My wife still has ios 6 on her ipad (she likes the look). I will do the 7.1 upgrade when it is released. Should there be any issues going from 6 directly to 7.1? Thanks!

There shouldn't be. I went from iOS5.whatever to iOS6.1 with no issues.
Just make sure to back everything up before you do it, just in case all doesn't go as planned.
I always do mine the old fashioned way, download the full OS via iTunes so if you've already got it linked to a computer and been using iTunes to do updates/syncing that's how I'd suggest you do it.

Flv audio sync issues & player 9

Greetings, I've been looking for a solution for weeks, and
thought I'd give the forums a shot.
I have a client site with 6 progressively downloaded flv
clips that play when a button is clicked.
The flv files are encoded with After Effects 6.5, and the swf
files are published in Player 8.
The video clips are made with an alpha channel of a guy
talking and are about 30 sec to 1 minute long each.
The problem is audio sync issues on certain computers during
playback even when the files are completely buffered.
The other problem is that these flv files won't play on
computers that have player 9 loaded.
I'm investigating whether there are audio sync issues when
encoding flv files from AE 6.5, but still really
confused about the player 9 issue. I was wondering if there
are updates to 9 I can recommend to my client
or if adobe knows of any bugs that are currently being looked
into.
Thanks,
Kevin

I may just be talking to myself here, but...
Could there be any difference in the way an flv plays when
you
import the flv to the stage, as opposed to playing it
dynamically
using the NetStream class? Could this cause any audio sync
issues? Does Flash Player 9 have any difficulties displaying
flv files loaded dynamically?
Any ideas from Adobe folks would be great. Thanks.

Audio Sync issues Premiere CC and AJA T-AP

I need to get the audio sync issues resolved in Premiere. Using CC with an AJA T-tap. I downloaded and installed latest firmware and drivers, and plug-ins. Audio is playing back through Mac Pro line output. When the T-tap is turned off the audio plays in sync with the video on the computer screen. When I turn on T-tap and give it a 200 ms offset, it plays back in sync with my external monitor, but the computer screen is out of sync. If I skip around in the sequence quickly and press the playback, sometimes the monitor is out of sync. I need my audio and video to be in sync on all screens all the time. How do I resolve this issue?
Thanks, Scott

Hi team!
cc: petergaraway
Wondering if anyone has any updates on the Premiere CC v AJA T-Tap situation?
I just bought an AJA to go with our new trash can iMac, which has been beasted out so it shouldn't have any performance issues. I have two thunderbolt displays for the edit and a Samsung LED TV on the wall for client monitoring. There is a 10m HDMI cable running to get to the TV, through walls and ceiling, which I just replaced to a cable with a booster in the middle because I thought that distance might be the first cause of the lag.
I guesstimate we are anywhere between 6-12 frames out at times. Also, the vision seems to be buffering, and thus at times jolts on the screen as it tries to catch up (or back) to the audio.
Audio is coming out through the Headphones jack on the mac to a small Behringer mixer, where I have monitor speakers for the edit and then wall speakers for the client. So I have been keeping the Audio output to the Adobe Desktop Audio. If I select AJA T-Tap it sends the audio straight to the TV, even despite going back into the system settings.
In Preferences > Playback, the AJA settings are to Match Sequence and Minimum Buffer. Playing with the m/s frame offsets doesn't seem to make any progress on the issue. And infact if I push it to 500m/s it only worsens the buffering problem I described above.
I went into the AJA control panel and have made sure everything is set to 1080p25 as our timelines will invariably always be 25fps (Australia).
But right now I am pretty stuck, and think our slight sync issue was better before I introduced the AJA T-Tap to our system, when we ran the HDMI straight out of the back of the Mac. Only problem now is I put the HDMI back there and I don't get a signal to the tv!
Would love any other thoughts or suggestions here.
Mike.

I moved from MobileMe to iCloud and all my contacts are lost! The only contacts I now have are from my Exchange account. Any help please. I tried "Import from SIM" but as all my contacts were on MobileMe, they're all gone!!

The only contacts I now have are from my Exchange account. Any help please. I tried "Import from SIM" but as all my contacts were on MobileMe, they're all gone!!

that happens for people who used icloud for everything but contacts. When they updated and went through initial
set up, signing into cloud enabled everything including cloud for contacts. Since they had zero contacts in cloud, cloud cleaned out their contacts, but synced everything else that icloud has, like calendars, reminders etc. If those contacts were never backed up anywhere - they gone. If there is back up in cloud, it needs to be restored.
Contacts sync in the cloud need to be turned off, right after restore.

Help please... Audio sync issues going from iMovie to iDVD (iLife '09 packa
