imovie problem - error report
I've spent a couple of hours editing an imovie project (v10.2.2). When I try to export I get an error message "This item cannot be shared while it is still referencing media on the camera." The video sequence I was editing displays the camera logo in the bottom left-hand corner to show it wasn't completely downloaded. There is no "re import" option on my file menu. Any ideas what I should do next??
