In QuickTime Pro you can record new movie and import into FCP but you have to, after recording to QT export a movie to Quicktime movie and set output to your Final Cut settings.
For recording go into preferences (not QT Preferences there are 2 ) and click on the recording tab and change quality tab to device native.
