Although I'm not one to insist a "stabilized" approach is the only way to go, I agree that this guy started too high (which would only be a no-no if Tower had asked him to arrive "right base" which would imply at normal TPA), then lost altitude too soon when he descended... would've been better off waiting. No glideslope indicator there, it seems- here's a case where it might've helped.
I believe I heard Tower call wind as 030/09 when they gave his landing clearance ; if I heard right, then with the angle of that terrain drop-off, seeing as he was quite low as he got closer to it, he may very well have gotten pulled down by a bit of a downdraft. Surprised the air flowing off that bluff wasn't more turbulent...he was lucky.
Whatever the case, he basically dragged it in, and had that happened to me, I'd have used power to get back up to a normal glideslope, and sooner... There was plenty of time to fix that up, and lots of runway to work with in case his final got too long, but perhaps he was scared to pick up the nose for fear of stalling. Although with plenty of power, she'd rise without much pitch input at all.
As for the flaps, I was always taught that if that last notch is to be used, one should wait until established on final, with a very definite feeling that the runway is "made". I never go past 20 degrees on base. But he sure didn't need more flap on
this approach!
I agree that he's likely pretty green- notice how elated both of them seem to be with that landing (because it was a smooth touchdown?)- or maybe they were just glad to be on the ground in one piece!!

Looks like a pretty place to go flying, though- very nice.
