MISSION

Skaters have been making commitments, pushing their limits farther. But they could not effectively pass on their experience to others without the right tool.

Consequently, traditional skateboarding tutorials always went like this:

  • Flick as hard as possible
  • Jump higher and try to stay in the air longer
  • Pop straight downward, etc

Although they may be correct, none of them could effectively describe what pros truly meant.

Instead, we need objective science behind tricks. By understanding the "WHYs" of tricks, everyone will be able to learn tricks more effectively.

With whythetrick's deep-learning mocap engine, you can enjoy these features:

  • Drag & Drop and the system converts your video into a 3D animation.
  • Change the camera angle and zoom in/out to detail your problem.
  • Show gridlines to see how far you should move.
  • Adjust play speed and make it super-slow if you have to.
  • Change the transparency of objects to see what you could not in the traditional tutorials.

Whythetrick's ultimate purpose is to create an eco-system where the entire human race can systematically store its knowledge and boost its evolution.

Be part of it. We are changing the future together.
