Sound gets out of sync when exporting video

Tomus

I have a videofile (mp4) with no sound and a soundfile (waw) from an other source. First I have to change the clip speed of the sound file to get it to sync with the video. That doesn't surprise me.

But then (when it is well synced in the editing) I export the video as .avi and plays it with Windows Media player, it gets out of sync as the video plays.

Why and what to do about it?

Export using mp4 instead of AVI. What version of VP is being run? Upgrade to the latest VP version, which may solve the issue.

For licensed users upgrades are free for up to six months from purchase date. After that, VP will continue to fully function but a fee will be required in order to register the newest. Retain your old install file and registration info.
