The title of the video is wrong. It's a punch front.
Regardless, you can do the same thing off of a jump (instead of a roller like the vid) to help flip yourself faster.
Stagger your feet, lean back for a sec, and then tuck and pop off of the foot that is further back. The tension in your ski will cause you to pop around faster. Be careful though, if you do it too hard off of too big of a jump, you'll overrotate your frontflip.
Good luck!
