Your video shows the plane landing on its belly almost immediately after the railway embankment. The report notes the entire wreckage path, from first impact with the wires to final rest was 1200 feet.
Did you allow for the additional 380 feet of distance before the second impact (1200ft-820ft)? It appears that would have been enough to put the beginning of the slide beyond the trees in your video. That also makes more sense of some witnesses describing a "cartwheel" and some describing a "bounce", i.e., if the plane were more or less still airborne for that 380 feet.
Cheers,
