Thanks Eric. Sorry for the confusion. The Zoom recorder doesn’t have frame rates of course. But I have my Sony action cams mounted on my plane. They are all set to 720/30p I then set my FCPX project settings to the same. But once the footage is imported and I analyze it in the FCPX session it shows 29.97. I assume those three frames over the hour of flight footage is shortening the clip and putting the audio behind? This is a recent issue.
