Does anyone know how rumble works?

Serious question. Does Rumble want vertical or landscape mode? Is there a minimum time for a video? Why don’t slow motion videos work on Rumble? Is there a cut off for getting paid on Rumble leaderboard? Why is Rumble posting earnings an hour before folks can still Rumble video?… Have y’all noticed anything else? Or will this video fail to load because I asked a few questions?
