Q: How do I reconnect media?
A: Go to File > Import > Files and browse for the original media files. If the files are already in the project, they will be reconnected.
There are two caveats: firstly, there is no way to reconnect to a
different file (such as if you were replacing a temp VFX shot with the finished one) and secondly, it will always copy the file to your Final Cut Events folder even if you tell it not to. The latter would appear to be a bug.
My software:
Pro Maintenance Tools - Tools to keep Final Cut Studio, Final Cut Pro X, Avid Media Composer and Adobe Premiere Pro running smoothly and fix problems when they arise
Pro Media Tools - Edit QuickTime chapters and metadata, detect gamma shifts, edit markers, watch renders and more
