Use C-up to change the view in a replay to directly behind the rider (the view you play in). Now use up and down on the D-pad to add a ''fisheye'' effect and zoom in (up) and out (down).
Instead of trying to time this; at the start of the race, as soon as the countdown begins just start tapping up on the Thumbstick quickly. When the race begins you will end up easily getting a fast start and will shoot out in front.
After completing a trick attack in the halfpipe, selcet ''View Replay'' and once it starts move the control stick to ''scratch a record'' in the music.
Do any race in Match Race and race until you are just before the finish line, then hit start to pause the game and select retire, your rider will continue and hit the wall behind the finish line, then get back up and keep riding into the wall. This is best tried on the deadly falls level...
Once the game into begins(with the boarder flying down the hill), simply hit C-up once, and then use the Joystick to move the camera around. If you'd like to go back to the pre programed ''action'' cam, simply tap C-up again.
