The two minute video shows some technical similarities to other media releases, the transitions and image slides along with the audio and file vision recording are from an intermediate level production rig.
However the content quickly dissolves any notion or sensibilities, and as Australian Prime Minister, Tony Abbott said, (here)
‘all you need is a knife, an iPhone and a victim‘
The content shows the beheading deaths of four soldiers and the execution of eleven others by gunshot. The pathos moment in the video, as the young man who shows his fear, gratuitously apprehended by the camera along with the blunted knife used by one of the assailants to prolong the pain and extend the dying.
