Canon 7D Does 1,000 FPS Slow-Motion Surfing Video Thanks to Software Tricks

Devin Graham filmed surfers off Oahu's North Shore with his Canon 7D and a 2X teleconverter (which converts his 70-200mm and 100-400mm lenses to 140-400mm and 200-800mm, respectively). As with other action sports that look great slowed-down, surfing benefits from super slow-mo, and so Dylan used After Effects to take his 60fps clips all the way down to 1,000fps. Here's the result:

Here's Dylan on his slow-mo-ification technique:

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. Another similar program that does something similar to this slow motion effect, is a program called "Twixtor". It's another great program that is very similar, however you have to buy it as a separate plugin, and it is a little expensive, but if you do a lot of slow motion, it's totally worth it :)

And here's a tutorial on using the Timewarp effect (on a surf video, no less) in AE:

This is a great example of how to use the timewarp/tixtor effect.

These time-remapping effects work well on fluid, organic constantly moving BG and FG. It doesn't end up getting all warped in a bad way. Notice the classic morphing and liquidification in the video when the surfer catches air. Pay particular attention around the surfers head here:

When there is strong edge detection between the FG and BG, or self-occlusion between elements of an FG subject (like and arm crossing over itself in front of a body), often, these liquid artifacts occur.

works best

It is a cool effect, but one that is instantly betrayed to a discerning eye very quickly.

It's beautiful, Dylan. Just wondering what's the minimum system spec that you recommend to process this work?

Looks far less warped than my previous attempts with Twixtor. Water, hair, and clothing creases were my worst enemy. I'm going to try out Dylan's technique. :)

The slow motion stuff in your clip looks great but the stuff you have increased the speed on looks gittery as, have you any idea on how to improve this.

Dylan, Your numbers don't add up as far as your comment "Canon 7D and a 2X teleconverter (which converts his 70-200mm and 100-400mm lenses to 140-400mm and 200-800mm, respectively).

If you take the 70 mm - 200mm x 1.6 you get 112mm x 320mm adding the 2X you get 360mm x 640mm.

As far as the 100 mm to 400mm with the 2X that would = 320mm x 1280mm.

Or did is miscalculate something?

Awesome vid man !! :)
I too tried out twixtor! Great plugin! Well if you use it smartly, check out how I came out with NO warping at all!

Rick, when shooting video you don't need to calculate crop factor. Many people don't calculate it at all, as lens mm is what determines them.

I've been wondering . How to make one person moves in normal time while everything goes in slow motion ?
