The video is from the F-16/Su-24 shoot down.
The following is video from the Syrian side. The rescue Mi-8 Hip helicopter was hit by ground fire and abandoned with the crew seeking shelter in a nearby building. The helo was then destroyed by the rebels after the crew was rescued by the Syrians.
The segment at 3:20 (firing at parachutes) is not from this incident but from earlier in the conflict before Russian involvement.
BGM-71 TOW video from your link showing the Mi-8 Hip at 1:40 in the above video being destroyed.
