Is it possible in virb edit to do picture in picture? I am trying to merge GoPro video with Fly6 video and sync with my Garmin 1000 to do the overlays.
It's definitely possible if you use 2 Virb cameras that are recording at the same time. When you import the video, Virb Edit recognizes that they were recorded at the same time and offers you a Multi-Camera edit mode (where the PIP option is). I'm pretty sure all of that is based on GPS and Time information that the Virb cameras gather so it's unlikely that you would be able to get the PIP with cameras that don't also supply GPS.
