PVC2300 recorded audio is not sync with video

Hi all,
I have a big big problem with my new PVC2300 network camera:
when I recording (from browser interface) the audio of the .avi file is not sync with video... in details in a record of 12-13 minutes the audio ends 8-10 seconds before the video... and I suppose that more lenght is the recorded file and more lenght is the desync between audio and video.
I use MPEG4 video stream at 640x480 30 fps and audio G.711 A-Law in mode "simplex - listen only".
For my usage this is a very big isssue... I hope there is a way to fix it.
Thanks in advice
Robert

I tried for 2 days for all possible configurations, editing: frame rate, quality, resolution. and type of stream (MPEG4 or MJPEG).
The only case that the recorded audio and video is sync is setting the SMB protocol to autorecord to a NAS.
But this mode have a lot of problems (.asf format, large file size and continuos recording without the ability to start and stop the recordings).
I think that the desync is a bug (a very big bug) of yours activex control that makes the recording.
I have find more or less a workaround using the Cisco Client... the program get an error on start (after unintall and install few times, and a lot of test, I understand that the only way to use the Cisco Client is running it as administrator.
Ok finnaly the cisco program works, but using it I found another problems:
after recorded, I tried to export a part of recording for testing the audio-video sync... the program gives me 2 format: AVI (without the ability to choose any other options) and ASF (with quality options). I tried first AVI format... the result sucks: bad video quality, 1,8 GB every 20 minutes and audio desync... no comment! ...then I tried the second export format: ASF...thats OK, the result is good... audio finally is syncronized with video.
My system is Windows Vista SP2 (32bit) and Internet Explorer 8... I tried also from an other pc with Windows 7... same problems recording from browser interface. I have installed on my system the lastest video codecs (for example: divx etc.).
For my usage I can use the Cisco Client but my ideal usage will be recording from browser.
I think these problems are very serious for a product as is this camera.
I hope there is a way to resolve they... maybe with a future firmware update or installing an other software.
Thanks
Robert

ITunes 11.01 on Windows 8 audio will not sync with video

I have a new computer that is running Windows 8, and I have had no issues with iTunes 11.01 thus far on it other than the fact that when playing videos, the audio will not sync up with the video.
With the ineptitude that seems to define Apple as of late, there does not seem to be any actual support for Windows 8, and the "support" channels do no good at all.
Any ideas as how to fix this problem?

I think Microsoft made the Windows 8 incompatible with Apple products on purpose, they want windows users to have to download apps from their paid service which is more expensive than Apple's App/iTunes Store

Audio does not sync with videos

Sometimes when I download videos from iTunes, the audio and the video are not in sync. This has only started to happen since I upgraded to iTunes 7. Is there a way to fix this or is it a problem with the download process?

David, I'm monitoring the audio through the line out of my Mac Pro, using a small pair of powered computer speakers.
It's a system I've been using for years, and haven't had a problem w the audio waveform not matching the audio I hear, until now.
Thanks for your response!

Audio is not synced with video after Exporting QuickTime Movie

I have Canon DSLR footage shot 24p/1080p on the timeline. Timeline settings are the same as the Canon footage settings.
When I Export a QuickTime Movie, the audio is out of sync...
Can someone please help with this issue...
Thanks,

Don't tell me...you edited the files the camera shoots without converting, right? The camera shoots H.264...FCP doesn't like to work with H.264. The problem is that it SEEMS like it will work, but really is rife with issues when trying to work with it. You have encountered one...loss of sync.
The proper workflow is to convert the footage first...
#51 - Canon 5D MkII / Canon 7D footage into FCP
Shane's Stock Answer #51 - how do you bring in footage from the Canon 5D and 7D cameras into FCP to edit?
You need to convert all of the Canon 5D MkII footage from the H.264 format that it records, to ProRes 422 (ProRes HQ is unnecessary...no quality difference) Yes, the file sizes get drastically larger. H.264 is an acquisition and delivery format, not an editing one.
You can use the Canon EOS Log and Transfer plugin that works with the 1D, 5D and 7D cameras. This plugin is great because it brings in the camera's TIME OF DAY as timecode, instead of starting each clip at 00:00:00:00 like Compressor or other conversion software will do.

Here is a tutorial on how to use it:

And the workflow for tapeless ingest into FCP:

But for a quick fix...change your SEQUENCE SETTINGS to ProRes...render, and then export.

Audio not sync with video using photo booth since os moutain lion was installed

Since OS Moutain Lion was installed my photo booth no longer function well, audio is not sync with video, the sound delay is obvious with the video outut wha can I do to correct this?

I've seen that problem in several threads, both here and in the Mountain Lion forum. I tried to replicate the problem but was unable to do so... so it's not a problem effecting all Macs. Try posting here - in the Mountain Lion forum - and see what you get as a search. There's one specific "More Like This" to the right on this thread but there doesn't seem to have been a solution posted.
Good luck,

Audio not synced with video on movie downloads

The audio is not synced with video on movie downloads from the ITunes store. I have downloaded many movies in the past from the same PC with no problem.

Hi Jimmyjoefl,
I understand that you are having playback issues with videos you have purchased from the iTunes Store. After doing some research, I found the following resource that describes your exact symptoms:
Troubleshooting iTunes for Windows Vista or Windows 7 video playback performance issues
http://support.apple.com/kb/TS1718
Here are some things to check if, when viewing a movie in iTunes for Windows Vista or Windows 7, you notice that a video appears distorted, intermittently pauses, or has audio that is out of sync with the image on-screen.
Thanks,

TS1718 Movie audio does not sync with movie

Hi,
The movies I have bought through iTunes store does not work properly. I bought two last week and when trying to play them back over the weekend, the audio is not sync'd with the movie playback. I have a Winodws 8 laptop and enough space for the films to be played. The software is all up to date and can therefore see no problem as to why this should not be working. Does anybody know of any way to resolve this to allow me to watch the films?
Thanks,
G

HT4589 When using compressor voice is not sync with video. What causes this and how to fix it, please?

When using compressor voice is not sync with video. What causes this and how to fix it, please?

Although you say you have let the battery drain, was it for long enough? Since nothing else that you've tried so far has worked, I suggest that you leave the iPod unplugged for at least four days, preferably a week. That way, if something is stopping the iPod from turning the screen on, then whatever it is will drain the battrey. However, since the screen isn't on, that may take longer than if the screen was on.
Then, after that time, plug the iPod into a power source and leave it alone for at least thirty minutes. Only after thirty minutes will it show any signs of life, but you should leave it until it is fully charged before trying to use it.
If you get to this stage, the fact that the battery has drained will cause the iPod to reset when it springs back to life.
Let us know how you get on.

Audio does not fit with video FCPX 10.1.3

Hi, I have a little bit unusual (at least for me) problem. I have old video from camera (maybe 20 years) on my HDD and I would like to edit it. Problem is the audio does not fit with video - when somebody talks it is apparently delayed. Can you give me a hint how to fix it in FCPX? I tried to detach audio and move just audio line but it is not possible.
Thanks

I tried it again from the beginning and now I can move audio to the right. I would just need to move video to the right, so audio stays still.. I need to delay audio so one option is to delete part of beginning of audio track or somehow move video to the right but it is not possible, i guess video track in the beginning cannot be empty....
It is difficult to explain

Audio not syncing with video in itunes

Just upgraded iTunes (to sync wiht my iphone 5C) -- after a few playbacks the audio stopped playing while video would continue (no issues with music or in any other video playback outside of itunes). I turned off the equalizer, which returned the audio track to syncing with the video, except when i expand to full screen viewing -- the audio gets off track again and never catches up. In looking through user comments this seems a frequent problem for iTunes with Windows, but I have OS X 10.8.3.

Voices are not sync with video after upgrade to imovie11

After the upgrade to Imovie11, the voices are not sync with the movie.
I digitaled a lot of Sony Handicam Video 8 (HI8) tapes, also many other tapes.
All the movies, incl. the new ones, has the problem with de voices.

I gather you are using DV files. Here's what you should expect after upgrading to version 9.0.2 of iMovie '11: if you have event-clips that are longer than an hour and half you will have a noticeable lack of synchronization near the end of the clip. The only way I know of reducing the gap between audio and video while still using iMovie '11 is to open the file in QuickTime 7 (not X) and trim the file so that only the footage your tying to fix is left. Save that shortened file and import it into iMovie. It should seem synchronized now. But there is probably a remaining problem: the picture quality is has been lowered by being in iMovie. To check this, open you DV files in MPEG Streamclip. If there is no improvement in quality, you're lucky. When I play my DV files (from Video8--the original analog 8mm video) in MPEG Streamclip the color and tones are much richer. In iMovie '11 (and, I think, iMovie '09), the picture is washed out, lacking color saturation and general subtlety. This makes all makes iMovie '11 (at least) essentially useless for DV files--if my experience is generalizable. What I don't know at this point is whether these two kinds of problems (lack of synchronization and picture degradation) are avoidable by using iMovie '06 or Final Cut Express.

Audio is off sync with videos on Ipod Touch.

My Ipod touch does not want to seem to play the audio in correct sync with my videos anymore. I have not done or changed a thing lately. Does anyone have any ideas? Thanks. I am running firmware 1.1.5

Update My iTouch is downgraded to 1.1.5 successfully. I used a pc that had an un updated version of iTunes installed (7.6) and after 2 attempts using the power off + home combination described in the firmware 1.1.5 post, I was able to successfully "restore" to the latest "1.1.5" iTouch software. When the touch reset, before establishing a sync relationship with the pc, I reattached it to my mac and selected "new ipod" rather than restore from backup. I then synced and tested on of the previously screwed up videos. It plays without any audio sync problems. This processes is more or less what the genius bar instructed me to do. I was reluctant to download any software not coming directly from apple. If anyone knows where the firmware file is stored on iTunes PC version, I would greatly appreciate the location. I want to save the file on my mac now that I know this is a good version. When Apple comes out with 2.1, I want to have a fall back.

Audio not sync with Video

I am using a Sony DVMC-DA1 to convert VHS tapes into Final Cut Express. After I finish capturing is says,
"The audio sample rate of one or more of your captured media files does not match the sample rate on your source tape. This may cause the video and audio of these media files to be out of sync. Make sure the audio sample rate of your capture preset matches the sample rate of your tape."
I have looked in books and feel that I have tried everything. The audio is still not in sync with the video. I am out of ideas. Does anyone know how to fix this?

What is the audio settings of your sequence? It has to match that of the video you're importing
I'm not familiar with the unit you're using to import but basically, if your video is 16 Bit 48K then your sequence, your timeline, as to be the same, say NTSC (or PAL) DV. If the video is being captured at 12 Bit, your sequence should be NTSC (or PAL) 32K.
Having mismatched audio rates in your timeline will usually lead to out of sync audio
