Video of jaw-dropping basketball shots

This is stupendous video of some guys sinking a series of jaw-dropping baskets in what looks like a skate-park. The shots are so fantastic that I have to assume there's some trick photography here -- these shots are the kind of amazing that makes you rock with surprised laughter -- but if this is CG or more traditional trick photography, then it's so well executed that we can move our praise on to the effects-wizards. 8.8MB Quicktime Link (Thanks, Christopher!)

Update: Brian sez, "the video is actually from DC shoes."
