Keywords I used in search include "Ultra slow motion", "Phantom HD" (the state-of-the-art high speed film camera) and "Super Slow motion"
To qualify as "Ultra Slow Motion" they have to be captured at 240 fps or more, and not some cheap video effect of stretching 30fps to 5fps or something. If you find any more similar videos that's not on this list, add the link to a reply and I'll merge it with the existing list. Enjoy!
