I’m working on a online FCP7 <-> FCPX XML converter, but the XML was a bit more complicated than i first thought so i might take some time.
The dev. version i work on “kind of works” but the generated (converted) XML are not good enough yet.
The way it works are simply that “user” uploads the XML from FCP7 or FCPX and gets a download dialog for the new XML file. I hope i can have it finished an online during this week.
