It's all in-camera, Paul. The Gopro Max has "horizon lock" which keeps the image level to what it was when switched on. This works in normal "Hero mode" like here, and also in 360 mode. 360 mode also has "world lock" which seems to keep the field of view in the same orientation as at switch-on. That seems a bit odd, it doesn't 'follow' bends in the road. This was the first test. It had a clip on clear cover to protect the lens, this steamed up inside later on.
Rainy Hardknott footage to follow.....
