Users may find that when working in iMovie and attempting to use videos stored in their Aperture libraries, they are not able to be used. This can be caused if the video files in your Aperture library are referenced files, stored in a location (such as an external hard drive) that is referenced and not managed.
Solving this issue is as simple as changing the referenced files to managed files. You can do this in Aperture, by selecting the offending videos in your Aperture library, then:
From the Aperture menu bar, select File > Consolidate Masters.
In the dialogue box, choose whether you would like to copy the referenced files to your master library location (this keeps a copy of the file in both locations), or if you would like to move the file to the managed library location. Once the video is in the managed location, you will be able to access it in iMovie.
