I cant view at video on my device right now, but by the sounds of it I would first check your ESC calibration and alsalso go trough APM setup wizard again and make sure radio calibration is done correctly and that you so not have any mixing on your radio.

Also check
Motor rotations are correct
Props are CW, CCW, 2 of each and on correct motors
Props are fitted with top (lettering) uppermost
