Shooting on C300 @ 50Mbps 1920x1080 on fw 1.8. Dumped card on hard drive, imported to FCPX 10.0.8. The image looks flickery and grainy. I then did a test with converting a clip via MPEG Streamclip to Prores and it looked fine in FCPX. When I imported to FCPX there was no option to transcode, only proxy media- unusual. Any ideas?
