Initial impressions from the video
Aside from the general "It is an ugly crash" feeling, I am noticing a bit of 'roughness' to the fuselage profile in the starboard lower lobe of the fuselage ahead of the tail. There is a lot of pixelation there, but it may also be an effect caused by a heavy vehicle or other cargo hitting that area and penetrating-probably when the starboard wing dropped to 90+ degrees of bank.
It appears that the humidity was fairly high and there appear to be faint vapor effects behind the aircraft including what appears to be a tight vortex behind the rudder just before initial ground contact.
As observed by others, the gear is down.
When the nose rises uncontrollably, the natural reaction is to fight it with all that you have to attempt to push it back down. Some aircraft I have flown had procedures to instead immediately drop a wing to prevent reaching a high nose up attitude when encountering an uncontrollable pitch up. Are such procedures used in the cargo community? Of course, this might not work well in an 'A' manufactured aircraft, but this was a 'B' with an entirely different control philosophy.
