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.
i find for learning fronts, you'd be better off trying them on a jump without a lot of kick, that way you can kinda push into it more. just pop into it, tuck, and rotate. it's not that difficult a trick
Larger jump, preferably into pow (a cat track with a steep in run and landing works perfect. This way you can hit it a ton and get the speed just right). And make sure you stay tucked...grab your knees and hug them to your chest if possible
