I bought Hitfilm 2017
I added MOCHA to a clip in my comp
I tracked an object, a lav mic on a person
I added a clip and it tracked perfectly.
I can't get the finished product out of Mocha and back to Hitfilm.
Export the tracking data in the track tab. How are you trying to export it? Are you using this method? http://www.imagineersystems.com/support/documentation/#ExportingTracks_to_HitFilm
Let me know and I will be happy to help you.
