I used VIRTUAL DUB which you can find with google.com There are instructions which you read, learn and in there is a way to shift the audio track. Sorry, but since all the notes are on the web site, I tend to not duplicate that content.
If you need to convert the video to a supported format, just ask. There are ways, but your post told very little about the format the video is in.
If the movies my camera takes has audio noticeably delayed after the video, what software programs can re-adjust the audio so it is in sync with the pictures? And how much should I expect to pay for them?
