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

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.

ITunes movie playback, audio and video not in sync after upgrade to Mountain Lion
After upgrading to Mountain Lion I have problems with iTunes movie playback, and the audio/video at times stalls/delays, or skips a few seconds, or even gets out of sync. I feared this problem was isolated to my machine until I saw an article online: http://reviews.cnet.com/8301-13727_7-57489874-263/sound-stuttering-after-mountai n-lion-installation/. I have 2011 iMac 27" with 16G RAM and am running the latest iTunes and Mac OS X software, and shutting down extra programs doesn't help. Please let me know of any solution.

Audio and Video not matching up
I have a video someone brought me to fix. Their problem is they have video at 48 kHz and audio at 44.1 kHz. What can I do to match the audio to the mouth supposedly making the sound? When I get it matched up in one place, the audio gets progressively farther off as you go along in the video.
Thanks for the help,
EricTheir problem is they have video at 48 kHz and audio at 44.1 kHz<<</div>
Ummm No. Video isn't measured in audio sampling rates. You probably captured video with the preset for DV NTSC 48khz (the 48khz is the audio portion). But your audio was either recorded incorrectly or from another source (CD audio perhaps?).
Use QT Pro to export the 44.1khz audio to 48 khz and import into your project - OR - use SoundTrack Pro to resample at 48khz.

Audio and video not in sync. Went back to previously edited projects and they too are now 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 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 out of sync after exporting sequence
I'm a FCP user since years, but not so common with HD footage. Therefore I have an issue with my finished edited movie after exporting: Video and Audio are out of sync.
My sequence settings are: HDV1080i50, 25fps, 48kHz, 16bit, Stereo. I used File-> Export-> Quicktime Movie -> Current Settings
Sequence has a duration of 61 minutes and 38 sec. I tried to find out where's the problem and exported audio and video seperated. This results in:
Video is 61 minutes and 27 sec long
Audio is 61 minutes and 38 sec long
That means exported video is shorter than original sequence.
What could that be ?I had the same problem with a Panasonic camera, even filming at 30 fps. I was able to fix it; see [this thread|http://discussions.apple.com/thread.jspa?threadID=1783029&tstart=0]. It's a frustating problem, to be sure. You might have to use Easy Setup a couple times before you get things to work properly. Not sure why that's the case.
Good luck!

Audio and video out of sync after capture from Canon
Help for a newbie please? I have a Canon XHA1S and have a problem after capturing HD video. After capturing a 40 minute clip, the audio and video are out of sync. Seems like there is about a 3 second difference. The entire clip is like that in the source window; I made a couple of quick edits and have the same problem in the program window. Tried exiting and re-opening PP, but that didn't help. I'm running PP in CS6 on an iMac 3.4 GHz i7 with 8G of ram. Thanks!
I have NOT used it, but many say to try this for HDV capture http://strony.aster.pl/paviko/hdvsplit.htm

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

Audio and video out of sync after converting to mp4
I've tried 3 converters (ImToo, Xilisoft, and Videora) and for 2 videos I really want on my ipod, the audio and video are offset. Infact, on Xilisoft, one wouldn't even convert (to anything ------as both are WMV and I thought that might be a problem--but I found I had another WMV that had the audio matching the video fine). For the other vid., I tried on Xilisoft making it an AVI first, but that AVI also had messed up audio/video
This is a really broad question, but what can I do and what programs can I try to get the videos to convert properly??
(I've tried uploading the wmvs to itunes to have itunes "convery for ipod", but they wouldn't even upload to itunes)
30gb video ipod Windows XPI have also had similar problems. Unfortunatly i have yet to discover a program that works perfectly. Just keep searching is really all i have to say. However if you do find it, could u please post it

Audio and Video out of Sync after Pro Res export
I´m getting an audio/video sync issue when I´m exporting to Pro Res.
I started off in a HDV1080i50 sequence. Audio sampling rate is 48khz. (16 bit depth)
The sequence is less than 20 minutes long. It plays correctly on the timeline.
When I export the sequence for DVD and view it on a set top it plays absolutely fine.
When I export the video to ProRes (422 HQ - I used Export using Quicktime Conversion) and the audio to AIFF, they quickly go out of sync. This was brought to my attention first by the guys who were making the DigiBeta master, and when I view the exported material in a Pro Res sequence I can see it for myself.
The audio and video clips are of the exact same duration.
Possible issues...
Some of the narration was recorded at 44.1 khz. I didn´t resample it (I´m still a learning novice..).. but if that is the issue should it not have affected the DVD as well? All the other audio in the project is 48khz.
Most of the material is HDV1080i50..but one clip used was originally an NTSC clip and therefore a different frame rate. However I converted it to a 25fps clip and this is reflected in the vid rate column in the browser where it says 25fps.
Final point, the exported AIFF files..when I import them back into the HDV1080i50 sequence and play back, it is perfectly in sync.
Any help would be greatly appreciated.First, yes resample the narration to 48k 16 bit. You will probably be able to reconnect to the resampled files. Usually works for me. That's a simple fix and will probably solve the problem. If it doesn't, you can try to change the codec (compressor) in the sequence settings to prores 422HQ, fully render and see if that solves the problem.
Wait, just reread your original post. Export from fcp using file: export: quicktime movie NOT quicktime conversion with current settings. If that works without synch issues, use compressor to convert to prores. -
Audio and video out of sync after import
I'm trying to bring some H.264 video into a Premiere project. But when I place it in a sequence (a sequence that is created based upon this very clip), the audio and video are about a second out of sync. (It's also odd: no amount of adjustment will bring them in sync. Seemingly the video is running at some variable rate that makes synchronization impossible...?)
As a test, I tried bringing my video into iMovie, and it works just fine there. But I don't want to use iMovie: I want to use Premiere.
Any ideas?Thanks. Here's the output:
