Reimporting from Camera for footage already in Timeline in FCPX I have created a video using FCPX using media from my GoPro and my Cannon camera, when trying to export the video I receive an error "Project has missing or offline titles, effects or generators".



I have identified the clips which are still used from external sources, however when reimporting clips as instructed nothing happens.



The files aren't imported, I'm stuck on how to export this file. I have tried disconnecting and reconnecting the media (the footage is still able to relink itself) but doesn't import. I have also tried restarting FCPX but that hasn't done the trick either.

UPDATE:
Actual error message when exporting...
The error you are having "Project has missing or offline titles, effects or generators" is kind of self explanatory, the project you are trying to export is missing on of the following from within the project timeline


Title (some text you have put on or used) 
Effect (a fade in or fade out, wipe, etc)
Generator (any one of the build in generators)


so if you watch the project from start to finish you will see the issue, somewhere on the timeline there will be a missing 

If you have not used any of these then there might be something wrong with the project and I would suggest re-doing the whole project again.

I don't think you have any problem with the "media" as such. Normally within FCPX you will see a "red" section where there is a problem.
