FCPX round trip to Motion 5 for stabilisation?

Does anybody know what the appropriate procedure is for using stabilisation in Motion?

This all seems really tatty at the moment and because of that I must assume that I'm doing something wrong.

Firstly, all my media is ingested into FCPX and Transcoded to ProRes - OK, it's in that event library now, nicely grouped by all my keywords.

Now, I want to get that media into Motion - the only way I can see of doing it is to reveal the media in the finder from FCPX, note the file name and then create a project based on that file in Motion.. incidentally I couldn't find a way of changing the project duration in Motion once it has been set. Changing it on the project settings just seems to be ignored and reverts back to the default.

Right, now I add a stabiliser, run through everything and then I have to do what? Do I publish this one off back into FCPX where it is neither nicely confined to a project or a set of events, it lives in a global area where my other effects live and that sounds like it's going to clutter things up when I've done with this project.

I'm sure I've grossly misunderstood the steps needed to use Motion to round trip a clip for stabilisation if anybody has any pointers then I would love to hear them.

Regards,
