Michael sent me an XML last night to check what can be done.
Here’s what you can do.
Download my TitleExchange:
https://www.spherico.com/filmtools/TitleExchange/TitleExchangePro_SL.dmg
Once installed you got several apps inside the TitleExchange folder.
Open TitleExchange and select XML Marker as source and STL Text as target format.
Import the Inscribe XML and save the STL.
Then launch XTI (you may read the help file).
Open the STL and convert to FCPX.
The resulting compound clip can be inserted into your project and merged down to the actual clips.

P.S.
With the above described workflow the apps are all free.
