Audio/Video problems

If you’re having problems with your audio or video, making some changes to your video will usually solve the issue.

Audio and video are out of sync

Make sure the duration of your audio and video tracks are the same. For example, if your audio is playing for 40 seconds but your video is playing for 50 seconds, that could be the cause of the problem.

You can use a third party video editor like Windows Movie Maker or iMovie to change the length of your audio and video tracks.
