Hi, I just picked up a new AC90 Panasonic camcorder. Adobe Premiere Pro CC blows through the two hour AVCHD file without so much as a hiccup or a stutter. On there other hand, FCPX (10.1.3) is completely overwhelmed with a constantly spinning pinwheel with the same file. It even has problems with the files with the files I've transcoded to ProRes. My computer should be sufficient. It's a 2010 12-core MP, 64GB RAM and a flashed and modded Radeon 7970 card. All video is on a RAID and not the system drive. Any thoughts?
