Devin Graham shot this beautiful surfing footage using a Canon 7D and a couple lenses (70-200mm and 100-400mm) with a 2x teleconverter, so much of the footage was shot at 800mm. The slow motion is actually “faked” (here’s another faked 7D video) using software:
To get the “super slow motion”, after I filmed at 60fps, I through it into the program “After Effects”. I used an effect that comes with the program called “Time Warp”. This allowed me to make the 60fps, to 1000fps. The way this works is the computer processes/adds frames in between the frames that are already in existence. It took several days for the computer to process the clips into the super slow motion that appears as well, so it does take a lot out of the computer, as far as processing goes.
Using After Effects or Twixtor to create fake slow mo is becoming a pretty popular technique. Beats shelling out big bucks to rent a high speed camera for many purposes.
