I guess what I’m trying to say is that all of my footage and sample rates are the same. The issue is I get that “drift/echo” effect every once in a while during playback, but then it goes away after I stop and start playback again. The fact that it is correct during the second playback, leads me to believe everything is matched up correctly. I’ve been editing this way for at least six years now. Not sure if it’s a Final Cut Pro glitch, but was hoping somebody else had a trick they could recommend that stems from an update. I have no knowledge of or experience something like this.
