It's real. When the guy realizes what is happening he has quite a realistic panic attack. And you wouldn't hear anything but he had the phone recording audio through the dji 4 app so this is plausible. This wasn't fake...but the question is whether it was set up or not. If you are brave/stupid enough to risk your $1000+ quad on 15 seconds of fame, bravo.
You wouldn't be able to hear the low warning from the drone as it descends. That's a red flag to me.
