Very good production value, true. At least two cameras, excellent editing, sound, music, post-production effects, etc.
Several takes, all cut together cleanly.
At 1:10, just look at that video camera. And they probably used two identical models of these cameras.
That's not what some kid can afford on his own. Someone rented or loaned that equipment for this production. Probably a director, screening and re-screening the shots, to make sure the takes will cut together smoothly.
So 'poet', two camera operators (minimum), director, back-end video editing. Probably a studio session to lipsync of the poem (ala 'music video'), since there is no ambient noise in the video its self.
The camera-in-motion shots are SMOOTH. Really good anti-jitter. If not on a rig. That down-swooping shot would be pretty hard to pull off with the camera held up over your head, walking sideways. A crane would do that way easier.
Yeah, some kid & his friends just knocked this out? No, they got LOTS of help and SOMEONE put CONSIDERABLE time, money and effort into it.
If you think the video will only be seen '1000 times', like this kid claims in the interviews, you shoot with whatever portable digital camera, in a couple of takes, probably with the built-in microphone. We'd hear wind, birds, aircraft, traffic, etc. from the surrounding environment. They show glimpses of the equipment to make it look less 'staged', but the equipment shots are definitely deliberately there, and present/absent, showing multiple, deliberate takes of the action being staged. An amateur would say, 'Crap! I see the reflector! Do another take!' Someone who put the equipment in on purpose would do extra takes to make sure they're framed right.
