For the November issue of National Geographic, the magazine filmed incredible slow motion video of cheetahs from the Cincinnati Zoo running at full speed. To accomplish this, the crew built a 410 foot dolly track and mounted a Phantom high-speed camera on it, along with several Canon 1D DSLRs for high-speed photography. The resulting footage is the first time cheetahs have been filmed at high-speed along a track and not from a fixed position. Here's the behind-the-scenes video of how National Geographic shot this footage.
