We just got a NXCAM from Sony. When I import the clips in FCP 6.0 (using log&transfer) something weird happens to the 1080i50 (pal) format. In 1080P25 no problems. Only with 1080i50. I've put an clip into my public folder to view what happens atfer import Public Folder http://public.me.com/fredinternet/frameproblem.m4v. The clip plays fine on the NXcam screen.
I didn't know where to post this message. But EX has a similar transfer process.
