I am having the same problem as Michael. I have downloaded the plugin and Codecs for FCPX I think but when I try to import all my MXF Files My FCPX crashes and it says because of the flamingo_/Sony/RAD plugin, is what makes it crash.
I have both FCPX and Premiere Pro if anyone has a solution or could direct me to a solution to convert my files to a ProRes or an editable file that would be much appreciated.
