I know how to export the raw data in various formats, but what I'd like to be able to do is; on an Android phone create a video of just the data-overlay for a particular lap or session. Then, my plan would be to merge that data-overaly video and the actual track video (from an external camera) using an external video editor.
So, is it possible to create a video of just the overlay ?
If so, does it have (GPS) time stamps?
