There is clearly a missile going upward, left to right then a detonation and we see the aircraft on fire falling right to left. If the reports coming out in US publications now are true, that may have been the second missile launched and why the man was filming, having seen/heard the first missile detonate.
Edit to add: Obviously with the caveat this is an authentic video.
