Toufee Flash Tip: Workaround to fix audio mismatch in the FLV video

If you had ever downloaded? your flash movie that has a background music attached, as a FLV or a AVI video file, you'd have noticed that the audio is out of sync with the video. When the rendering engine converts the raw Flex flash movie to a video file, there always seems to be a differential delay in matching the video to the audio track. The differential delay is caused by various factors such as the current load on the server, pending requests, etc. We are still trying to figure out how to normalize the delay factor so that audio mismatch effectively be nullified.? However, a workaround to the problem, though a bit lengthy, is this:

1) Remove the sound track from the flash movie. The following KB article provides instructions:

2) Download the flash movie as a video file (this renders the video without the sound track)

3) Use a third-party software such as Windows Movie Maker, DubIt to add the sound track back again to the video file. DubIt can be downloaded from the following link:

The following page has tutorials on how to use DubIt to add a sound track:

I hope that helps. We still do apologize for the inconvenience caused by the audio timing mismatch. Our engineers are working to see if there is an alternate fix that they could implement to resolve the problem. Note that the issue happens only when the flash movie has a background music attached to it.
