Of course, it's an edited version of the video with no audio. I wish there was somewhere that kept these online, every time there's a new one released I have to go hunt it down, usually off some gore site filled with weird shit.
EDIT: Full video is 38 minutes, found it here https://videos.files.wordpress.com/TneJgWZZ/isis-ninawa_hd.m...
Drone stuff seems to be towards the end.
