Audio and Video Out Of Sync

[Coat]

I am trying to download this video:

All the audio and video is in sync in the flv file, however when I convert it to any other file type, it 'jumps' over a few frames at about 4 mins 33. After that the whole thing goes out of sync.

Does anyone have any idea what to do?

I am having the same problem. Everything is in sync when in .FLV but jumps out-of-sync when I convert to .WMV form. It is only happening with certain videos I am trying to convert. Never had a problem with this particular video before and not having a problem with other videos I record regularly.

The way I deal with this in the odd occasions when it happens is to adjust the playback speed. I use VLC Media player. After loading the file go to either Tools or Playback for speed adjustment or sync.

I am experiencing the same - audio and video out of sync, but as I need to burn the result as a DVD, this fix doesn't help. Any other suggestions?

I've had this problem, too. I don't convert the video but for some reason the audio and video are out of sync when I play the file in the Applian FLV player and in WinAmp but not in VLC.

Hi,

I'm having a problem with the converted files, avi and mp4 (the only ones I use), since a couple of weeks.
The FLV files I want to convert are OK, sound and picture are completely in sync, but when I converted the FLV files in mp4 or avi files, suddenly the audio is out of sync with the video. Appears something went wrong during the conversion...
I have tried Replay Converter as well, and here too the audio goes out of sync AFTER conversion...

Hopefully someone can help me out with this issue!

Thanks!

I too am having this problem.

Plays fine in sync in the flv player, however as soon as I upload the file up to youtube.com it goes out of sync.

Any suggestions please?

Curious if there are other people having this issue?

Is it possible it could be linked to the newest Flash update? I've been having problems ever since I updated... Or is this just a coincidence?

I don't want to hijack this thread, but I've noticed that webcams downloaded from Cam4.com are always out of sync (without converting). Every webcam starts with the audio/video in sync, but the longer you download a webcam, the more out of sync it gets.

A 5 minute video is often a few seconds out of sync, but a 1 hour video is often 6 minutes out of sync.

If I dowload a webcam from Cam4.com with StreamTransport or with the commandline tool RTMPDump, the audio/video is always in sync, no matter how long the video is.
