XTI functions are now nearly completely integrated into TitleExchange.
So you can for example directly import .sbv files to .fcpxml files (was requested here some weeks ago)
This means you can transport more than 40 subtitle formats directly into FCPX using the title template you want or need.
Cause of a user a request I've added a new import format: feet/frames to restore old subtitle lists to modern media.
The interface has changed a bit for the conversion setup to make it easier for users with a small display.
As always most of the functions are free to use with no limitations -- some do have limitations but there are workarounds for the user.
