Missing media in Final Cut Pro
Hi all! I've just complete a project on Final Cut Pro X 10.2.2, and two large video files on my phone seem to have problems importing.
I've imported files to Final Cut on this computer from various devices/cards/port in the past, including from this iPhone 6, with no problem. Usually, the background task window will show when those imports are in progress and this was the case at first with these two files as well, though it was taking longer than usual; so I kept editing my project for several hours giving it time to process. By the time I finished, it appeared as if the files were imported. Then, when I tried to export the video, I received an error message saying I wouldn't be able to export so long as my project referenced files that were still on a camera--but didn't say which files it was referring to. So I closed Final Cut and restarted it, and realized the missing media files were the two videos on the iPhone. But when I tried re-importing them, I couldn't because it said the camera wasn't attached (it was). I tried just importing it again, but the software doesn't react when I do so, and background tasks do not show any import taking place.
My next troubleshooting step is to delete the files from the library completely and re-import them, but would prefer not to because I think this will cause me to lose edits I've been working on for the last several hours. Anyone have any suggestions or ideas? Thanks so much!
