If any software can somehow help you with glbtablx to ama conversion, it is certainly ArcGIS, the very same software that uses both these files. Maybe it is export of geodatabase data or something similar, maybe animation of tracks saved in .ama files. We have not found any useful information about such export, so if you struggle with it or need further help, it might be best to consult ArcGIS support or perhaps reach out to the online community.
