The best way to import clips that use a high-end, proprietary codec (eg BRAW, R3D, etc) from Final Cut Pro into Eddie is to:
allow FCP to create h264 proxies on those clips
then drag the clips from FCP to Eddie
Eddie by default looks for a proxy attached to a clip. It will import the h264 proxy. Once you get your edit in Eddie, you can send it back to FCP and the clips will seamlessly relink to the source.
TaDa!
