I get the same thing when I export a reference movie. I’m not sure what FCP is doing but it’s doing something. One thing that I’ve noticed is while it’s doing its thing the viewer, canvas, and timline windows will all be dimmed. Once its done you’ll notice one of the windows will be active and now you can start working again. It usually only takes a minute or two.
