A new product was literally just released that does this. "PrimariesExporter" will allow you to export individual clips from the timeline from ProRes Proxy to ProRes 4444XD. http://www.fcp.co/final-cut-pro/news/1591-output-batches-of-clips-from-final-cut-pro-x-storylines-with-primariesexporter This is the great thing about FCPX, it's also the great thing about the iPhone. Apple created a solid foundation that developers can build off of and create useful add-ons for the people who need them.
