Problem with online flv flash video and audio sync

[HELLIAN]

I cannot seem to sync audio / video on a flash correctly. I am trying to imposr avi files into a FLV Flash Video Burner 2.1.9 and exporting them out as flv but the problem is video plays fine but audio is out of sync and running after a long time when a dialogue is already spoken in any movie. So can anyone tell me how to correct FLV audio and video sync problem, so that I can view my original converted file properly. Thank you

I think your FLV file might be lacking metadata which you can add with a program they have on the site called flvplayer.com or it maybe because you are recompressing already compressed data. You need to save your movie out uncompressed before recompressing as an FLV.

First try to load the video into AVI Demux. You have to re-encode the audio

Do everything else the same, but instead of "copy" for the audio sidebar, use "MP3 (LAME)" and press "filters" (under audio) => gain mode => automatic -3db

If that's not loud enough for you choose manual and enter a value .

I think there is a limit of 16,000 frames in flash (per movie ??)

16,000 frames divided by framerate 25/s gives you how much time before the encoder stops
(just over 10 min)

Just guessing for now.

If the "out of sync" issue remains constant all the way through the video (in other words, it's out of sync at the beginning for 1 second and the same at the end), then you can delay the audio by a second or two. Most editors have the ability to do that.

I had to do that for a few videos I put up on
