A year ago, BASE jumper Jeb Corliss defied death by jumping off a mountain in Switzerland wearing only his wing-suit and five GoPro cameras. A few days ago he processed some of his video through Twixtor. The crystal clear results are insane.
Twixtor is an artificial video speed software filter that works in programs like After Effects and Final Cut Pro. It analyses footage, estimating motion and creating new frames as needed out of pure magic, speeding up or slowing down your video. I'm in awe. [YouTube and Twixtor via Petapixel]
