Thanks Danang for answering my post.
I think i get what is the problem you said,
During some months in the video, we can't see night time (we see 24 hours of daylight)
That only can be possible if the sun remains visible all day. and appears to be rotating around a pole(regardless of the direction of rotation).And since Tromso is near north it shouldn´t be possible in a south pole centred flat earth, right?
My sincere apologies If I misunderstood what you were trying to show.
