Watch out using XDcam Plugin v1.2, it kills or disturbs all the effect, generators and plugins
I installed Sony's Plugin for XDcam v1.2 in to both my Mac Pro systems containing FCPX v10.0.9 and on both my FCPX software, the effects, generators and 3rd party plugins were killed or disturbed. After installing Sony's plugin for XDcam v1.0, the Effects, generators and all my other plugins were working great again.
