There are frames lost or at least portions of frames lost. You may not see them or hear it when watching the video and that is fine if you’re intending on using the on board audio only for your video. Recently I had a 50 minute clip that I had synced perfectly to a soundboard recording track. By the end of the 50 minute the on board audio and the SBD track were just off to the point where you could hear the audio echo. The loss of frames (or portions) is the only thing I can figure would cause this.
