I'm having some problems syncing my video and audio. Basically I recored my voice with audacity, then the game video and audio with action. Then when I line it up in my time line to the point where I say something that matches up with whats happening in the video, a few seconds later the audio falls behind. whats going on? :/ no cuts were made so I don't understand how it can go fro mbeing in sync to out of sync. Any help?
