Want to make video + 2-hour continuous; Can't.

Want to 2-hour + video continuous; Can't. I want to make a video for a long time. Point to the baseball diamond, leave it alone and save the League game shortly together when my grandson is pitching. Clearly there is enough memory (64 GB) and enough battery for 2 or 3 hours, but he stops recording "automatically" after about an hour, and I can't find a way to control that.
