It's a nice film, but like most other timelapses of the Northern Lights, the auroras are moving way too fast!
It is totally unnatural and frenetic, and nothing like watching it for real.
In my opinion the northern parts of Norway are better for photographing the auroras.
The coastal areas with the fjords and mountains makes for far more dramatic photos than the flat woodlands in Finland.
However, the chances for a cloud-free clear sky are better in northern Finland. The weather in the coastal areas of Northern Norway are more unstable, but with the right conditions the auroras can give you an awesome experience.
(BTW, this is my first post here, hello to you all. I am a photographer living in Tromsø, North Norway.)
The first 3 photos are from the Lofoten islands in September, the last one from a fjord close to Tromsø.
