In the beginning of the video he shows exporting the terrain in LWO (Lightwave) format, which is the only natively supported export format at this time. OBJ format is coming in a future update. While he does later show importing in OBJ, there must be a conversion step left out because the LWO exporter also exports in multiple tiles, as he shows earlier, and the OBJs are single objects. Perhaps it's assumed that you know how to load and merge multiple LWOs into an OBJ.
Unfortunately we did not create these videos, we are using them with permission from Xfrog Software who developed them. So I can't say what specific steps were used to convert from LWO to OBJ, but that would be outside the realm of TG2 anyway and more of an app-specific workflow.
