I use an external battery so I can record very long videos, so today I made three and a quarter hours, but when I checked the overlay data after the two first hours the system lost the data. I tried several times, also replacing the data of the virb XE from the edge 1000, and the same problem occurred. So finally I made two exported videos, one of two hours and the other of one and quarter hour. I would have preferred to have only one video so the tracking of the route appeared completely in the corner.
I suppose it is a limitation of vird edit software, that does not expect so big files.
Please check it, for the next release.
