WOW dont think it is 2 videos coz u can c the net of the hoop react to her passing through and if some1 fillmed it with a basketball through the hoop the ball would go through the hoop at the same time as the girl and therefor it would be very difficult to remove the ball without removing the girl.
besides the ball would be behing the first layer of net so again it would be very difficult to remove the ball without removing the net.
unless it was done professionally and used a blue screen and blue ball and removed all of the blue from that scene and then layered it.
seems a bit too much trouble to go through though lol
