I'm having trouble exporting quality video from FCPX. I have great, sharp Full HD source footage, but the moment I import it into FCPX 10.2.3 for editing the quality degrades significantly. I don't want to use proxy or optimized media, but FCPX is not giving me an option. Exporting a master file is even worse than the imported footage. How can I just work native and preserve the original quality?
