Audio and Video not synching after export

I've uploaded DV from my camera into iMovie. In iMovie, audio and video are synching perfectly, but when I export to Quicktime they are off by about a second (or two). I've tried several different "expert settings," but still no dice. I've not had this problem occur before, so I'm confused. Anyone?

Make sure none of your clips are using custom slow motion percentages. Only use what the slow motion slider snaps to. I had the same problem and once I changed my percentages to what iMovie wanted everything exported correctly.

Audio and video not synched up....

Hello everyone. I am having a problem with my i-movie and was wondering if anyone here might know what I need to do to solve it.
The problem is that the audio and video are not synchronized when I capture a movie.
Any suggestions?

Hello and thanks for your help. May I pursue this with you further? I think I figured out how to separate the audio and video, by using the imovie help. What i have now is a green bar that appears all along the bottom of the video frames.
I'm having one problem. When i move the audio, and then play back the track, both the new audio position and the old one play, so I get this echo effect. Do you know how I save it without the old position?
Also one other problem I'm having is that when I record video, for some reason whole chunks of the recording are missing. I don't know what is causing this....

Audio and video not synchronized when exporting from Premiere Pro CS6

Hi
We have made a project in Adobe Premiere Pro CS6 that´s intended to be exported to DVD (it´s a weeding). We are working with NTSC DV Widescreen. The exporting is 720x480
We have 2 audio lines activated and sounding on this project.
The question is:
When exporting the entire video (the entire timeline sequece) using Adobe Media Encoder to formats like H.264 (NTSC DV Widescreen)... Quick Tile Movie or AVI without compression (we tested these formats) the 2 audio channels get unsynchronized from the video. The same problem occurs if we get a direct link of the timeline from Premiere to Encore.
And Inside Premiere Preview audio is preety correct.
Does anyone here are getting such problem?
Also..can I ask another question (as I´m not expert on video production)?. What´s the best format for our purpose? Export a video to be played to DVD (we record weedings, birthdays..social events). No problem the time to export. We´d like the best quality for output.
Thank you for the help
Gustavo.

Hi John and techkid123
We have 4 cameras here. 1 is Sony model HD1000 (since it works with Mini-DV cassete we need to capture the image via Firewire). 2 cameras are Sony HD2000 (it generates *.MPEG files if I remember well). And 1 camera is a Panasonic AG-DVC7 (it generates *.MTS files)
We start a new project using the Standard NTSC Widescreen 48Khz format. When we drag to the timeline for example the MTS file...Premiere ask us if we want to Keep and Change timeline to suit the file specification. Anyway we always have 1 or 2 camera files that has a yellow line over timeline.
But I renders correct...no problem to edit...and we had no problem with Premiere CS5.5 :/
We are downloading the latest update of Premiere. I´ll make some test and publish here if the problem persist.
Thank you a lot for the help
Gustavo.

Audio and Video not synched on import

I am trying to import a video shot on a Canon XH-A1 in HDV. WHen I import it into IMovie in HDV it previews at 1/2-real time and the audio is off by 2-4 seconds. When I import it in DV it imports correctly with the sound being synched however I lose the definintion of HDV.... Can anyone help me, is this a Canon issue or an IMovie issue???? Thanks in advance..

Welcome to discussions, Prescottphotog
Have you tried importing the HDV to imovie, then saving, closing and relaunching imovie? It may be that the audio will be in sync once iMovie has had time to cache it properly.
That's a lot of information for it to take in.

Audio and video not synched in FCE

How did this happen, and what do I do?

More details please.
Is audio out of sync in the Browser? The Viewer? Timeline?
Probably what is happening is that your Sequence audio settings don't match your camera settings. In other words, if you recorded your audio at 12Bit 32 K your Sequence has to match that; you probably had an Easy Setup of 48 K which is 16 Bit.
This is all assuming we talking about DV material captured as such. If you are importing video some other way, like from iMovie captures or some other non DV/HDV format, we need to know

Audio and video not in sync. went back to previously finished projects and they too are not in sync. What could be the problem?

Um ... some useful data?
OS/CPU/RAM/GPU/vRAM ... version of PrPro ... and other programs or plugi-ins/3rd-party apps involved ... footage type/codec/wrapper ... such things would be very useful.

Audio and video not in synch after upgrade

I have 12.1.1.4. I'm using this new version for the first time tonight, to watch some Walking Dead episodes, and the audio and video drift out of synch. I can bring them back into synch by pausing then replaying, but it doesn't last. I watched some older videos that I know to be good and had the same issue, so it's not a problem with the episodes.
What I've tried:
Making sure that the Quicktime audio settings match the ones on my sound card.
Uninstalling and reinstalling iTunes.

I also have this problem, and some videos will no longer play in iTunes.
I get a message that this video is not compatible with this version of iTunes. I have to open the video in Quicktime to watch it.
Unacceptable! This hardware and software is too expensive to have these performance issues.

Audio and Video not matching up after compression

I made a video that is 3:18 minutes long and after about 2 minutes, the audio and video don't match up anymore. I have 2 clips in the video that i conformed to 24p in Cinema Tools and i think that they are causing this problem. I noticed that Audio rate of the clips that i conformed, does not match up to the clips which are not. For example, the audio rate of my 59.94 fps clips is 48.0 KHz, and the audio rate of my 24 fps clips is, 19219 KHz. Is there any solution to this problem? I read a post that said i would need to re-digitize the clips, but i don't know how to do this. Can anyone help me?

I still can't figure out how to solve this problem. I tried to resample the audio, but still, same things happening. If you watch the video, the audio goes off about 2 minutes into it. The audio is correctly matched up with the video when i view it in FCP, but every time i compress it, audio goes off in the exact some spot. Here is a link to the video- http://vimeo.com/21619542

Synching audio and video not working

I recorded a separate audio and video clip of an interview, and I marked the start of the clip with a clapperboard and spoke the take number and contents to make life easier, as I usually do. The gear is borrowed from the college, and for some reason the audio that came out of the Canon 5Dmkiii was really low. This could be the reason why, when I put both the video and audio into their own bin and right click and merge clips, (with the syncronisation point as audio, and under audio tab checking the box to remove audio from AV clip) that the clip doesn't seem to recognise the snap of the clapperboard or something maybe? Is there any way I can correct this, or do I need to synch it manually? If so, is there any quick and easy tutorial on youtube or something that is recommended?

I discovered that if I put markers manually on the point where the clapperboard snaps, and select marker instead of audio as the synchronisation point, then it synchs up the clips properly.

Audio and video not in sync when exporting to Quicktime file

I use a digital camera to shoot video, which is in .avi format. I then import the clips into IMovie HD (selecting all the clips and dragging all at the same time into IMovie). If I play the video from beginning to end in IMovie, the audio and video line up fine. But, when I 'share' to Quicktime file, the longer the video is, the more out-of-sync the audio and video become.
I didn't have this problem when I used a mini-DV cam and imported using a firewire cable (in real time).
Any ideas as to how to get the audio to sync up with the video once it's shared as a Quicktime file? I've tried .mp4 and .mov, and I have the same problem.

Anything here help?

Audio and Video option missing from Export Quicktime Movie Include

Today as I was exporting a clip, I noticed that the Audio and Video option was missing from the Include drop down. I only have the options of Left, Center, Right.
I highlight the sequence, control E (or File>Export>Quicktime Movie) and the Save window comes up. The Settings drop down is the same, the Markers: drop down is the same, but the Include: has the options of Left, Center and Right. I thought the Video and Audio dropdowns were always there. I hate to admit it, but I have not paid attention to them in a while. Getting old I guess.
Sequence settings is 720x480 NTSC DV (3:2)

Thanks

Thanks, forgot about that.
For what ever reason it started working correctly a couple of hours later, after I started an SD project. The video came out fine
I had been trying out a couple new applications, so maybe one was causing it. I will see if it happens in the future.

Photo Booth - audio and video not syncing

I was making some videos on Photo Booth and the audio doesn't start playing until 5 seconds after the video starts! Do you know if there is any way to fix this or is it a software issue? I have tried resetting the computer but it didn't help.
Thanks for your help!

In Photo Booth, right-click on the video and either Export or Reveal in Finder. Either way, then open and play it with QuickTime. Is audio and video still out of sync?

IChat Audio and Video not working correctly...

Hi.
I recently upgraded to Snow Leopard. Before upgrading, I was able to video chat with little to no problem with family over iChat. I just tried it again today for the first time since upgrading to Snow Leopard and the audio is barely working (can only make out every few words, if that), and the video is extremely distorted to where you can sometimes not even tell there are people there. It gets all pixelated and weird. I tried doing the chat with Google Talk and then again with Skype, and had just as many problems with those. My family is using a Mac with an older OS, and they can see and hear me perfectly fine. I'm not sure if the problem is with my computer or with theirs, or if it's just a communication problem, but any ideas would be really helpful. Thanks!

After iChat developed missing audio and video pixellation problem post Snow Leopard installation at my mother-in-law's machine (and ours), I tried the usual decrease the bandwidth fix to no avail.
The solution that actually fixed the probem was to turn off port forwarding protocol on her Time Capsule and our Airport Extreme. Things are now working smoothly even at 500 kbps settings on both ends.
An interesting aside... Turning off port forwarding for ssh to her machine doesn't kill the ssh port tunnel from the outside LAN to her mac. It looks like iChat and the Time Capsule keep an incoming ssh tunnel open even if you have disabled port forwarding on the Time Capsule. I suspect this "secret" opening of ports is the magic of why iChat and screen sharing have been so much easier to set up when a Mac is behind an Apple router. 3rd party routers need ports manually forwarded to the Mac. Apple routers just worked ---- and it looks like Apple does it by invisibly opening ports on their routers when a Mac runs iChat.
Pretty nifty, but also silently opens a security hole that you may THINK you closed. SL seems to trip up over this arrangement when you also turn on Port Mapping Protocol and manually assign ports to forward.
At any rate, it wasn't the data rate, it was a new bad interaction between the Apple Router's Port Mapping Protocol and iChat 5. Turn off PMP on the airport and all becomes well once more.

Please help with audio and video not syncing.

I'm using Encore 3, and have already authored a DVD a month ago without a glitch. The following are the same steps I used, but this time around, the video and audio in Encore are not syncing.
Here's what I've done.
1) I export my Final Cut projects to .mov using the following settings (Share > Master File).
Format: Video and Audio
Video codec: H.264
Resolution: 1920x1080
Audio file format: Quicktime Movie (AAC)
Include chapter markers: Unchecked
Roles as: Quicktime Movie
2) I run the .mov file in Compressor using the "Disc Burning" preset.
3) I then import the .ac3 and .m2v files that Compressor created into Encore.
4) In Encore, I select both files and go to New > Timeline.
In the Timeline window, the durations on both are the same. But I don't understand why the audio and video are not synced when I preview or when I burn a test DVD. The audio comes in just a tad late.
Video Clip:
Source In: 00;00;00;00
Duration: 00;02;33;29
In-Point: 00;00;00;00
Out-Point: 00;02;33;29
Audio Clip:
Source In: 00;00;00;00
Duration: 00;02;34;00
In-Point: 00;00;00;00
Out-Point: 00;02;34;00
What's puzzling is that two of the 10 videos I've import to Encore are synced perfectly -- same export settings from FCP, same settings Compressor.
Please help.
Thanks!
Mark

Hi Mark.
Do you have any situations where there is more than one video file in a timeline?
Secondly - why are you using H264 HD files for a DVD? This is using lossy compression to make the H264, which is in turn then scaled & even further bitrate reduced for M2V.
I would give it a try rendering an SD video file for use in Encore - not the H264 - and starting out with Dolby Digital or LPCM audio, not AAC.
As with all DVD authoring programs, Encore works best with DVD compliant assets - which you are most definitely using - but I still think you are over-complicating things by using H264/AAC at all.
Eliminating this may help.

Audio and video not synchronised at Visio

When I play video at my Zen Vision:M, the audio and video is not synchronised. I don't know if it is all of my video, but at least most of it. The video and audio is synchronised when I play them at my PC.
I have the newest American firmware, .4.0 (because of European volume cap), and the problem did maybe come after updating to this.
Does someone else have this problem, or does someone have a solution?Message Edited by trygveaa on 07-05-2006 02:20 PM

the itunes doesnt play the sound but when its on the ipod it plays back fine till the last 20 mins or so.
