1. Load a student.
2. Position the video so the student is ready to start his/her back motion
(make sure to zoom out enough that the motion stays onscreen throughout the stroke).
3. Click on the Path button.
4. Use the left mouse button and click on the center of the ball (or whatever object you want to capture the path of). This is the starting point of our path. Note: The video will advance one frame every time that you click on the ball.
5. Click the left mouse button on the center of the ball again. The line drawn shows the exact path of the ball.
6. Repeat steps 4 and 5 until you have captured the entire ball path you are interested in seeing.
7. Click the Path button again to turn the button off. Note: You can also right mouse click or simply complete the entire video to turn the button off.
Note: You will notice a difference in color in the Path object. If you draw the path of a student on a horizontal plane (side view), this difference in color will represent the "High Speed Point" of the motion. Note: Any other camera angle other than horizontal will produce incorrect results for the "High Speed Point".
