The only sound is the noise from the rotors and the wind, so turn that way down. The video is full 1080P, but for some reason it only uploaded 720P to Youtube. I'll see if I can fix that later. Make sure the quality is set to 720P (its the little gear in the bottom grey bar).
Near the middle of the video the picture is a little wavy, I guess there is software or hardware to compensate for the harmonic vibrations.
Because it was fairly windy, he didn't come down too low. The altitude is probably about 80' most of the time.
