There's some videos in here about how to do impact hammer jumps and has videos of jumps in Sandstorm and Suspense.  The videos are from [k1]SensationBlack/Re-Ignite.  There's also a forum over at http://www.vctfheroes.com/ dedicated to teaching tricks.  A lot of k1 members view this site (k1 members are masters of these jumps).
