Sorry for the mess of replies, but I think I understand the issue more fully now. As it was explained to me, the FCP playhead sees the beginning of a frame, but when you set an out point the marker is placed at the end of the frame. Therefore, you won’t see the out point marker on the same spot as the playhead but you will see it on the in point marker. I hope this clears up any future confusion, as I found myself scratching my head at some of the previous responses.
