I couldn't resit trying out another one - 90-roll illegal (90, lincoln, 90) - I've seen people on here calling the trick an overflip - whatever (click for bigger version):
To capture the video I tried out a whole bunch of programs from download.com and eventually ended up using SnagIt 6. It still runs very
slowly with that program though (hard to get a good jump), even on my 2.56GHz, 512DDR. There are probably better programs out there - have a look around. Best thing might be to record it from your video card's TV out onto a camcorder, then load it back onto your computer for editing, I don't know.
To put it together I used Photoshop of course - I had the level background (ground_001.jpg or something), and used that to line up the frames. Then mask off everything but the skier and tracks in each frame.
Post your work back in here if you make anything.
